It is a chemical agent used in water purification, the pH regulation of garden soil, and other commercial or industrial applications. Medically, it is primarily used as a coagulating agent in minor cuts and abrasions as well as deodorant. Aluminum (Al) is ubiquitous and represents the third most common element in the Earth’s crust. It most commonly exists in a combined state with various other elements. Al is found in materials used in the pharmaceutical industry, and in manufactured foodstuffs, cosmetics, and tap water. By overcoming the body barriers, Al may infiltrate into the blood and lead to toxic effects in liver, bone and the central nervous system.|Aluminum Sulfate Anhydrous is an aluminum salt with immune adjuvant activity. This agent adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation.

Toxicity

moderately

Aluminum Sulfate, Hydrated (ACS & FCC): ORAL (LD50): **Acute:** >9000 mg/kg in the ouse [MSDS]. >9000 mg/kg in the rat [MSDS]. **Acute Toxicity** There is little indication that aluminum is acutely toxic by oral exposure despite it is widely found in foods, drinking water, and many antacid preparations. In 1988, a population of about 20 000 citizens of Camelford, England, was exposed to increased levels of aluminum for 5 days. The aluminum was accidentally ingested by the population from a water supply facility using aluminum sulfate for water treatment. Some adverse effects observed were nausea, vomiting, diarrhea, mouth ulcers, skin ulcers, skin rashes, and arthritis-type pain were observed. It was concluded in one study that the adverse effects of aluminum sulfate were primarily mild and transient. No long-lasting effects on health could be attributed to the exposures from aluminum in the drinking water during this period. **Chronic Toxicity** In humans, excess exposure to aluminum via dialysis water (aluminum sulfate) is a known etiological factor in several pathological conditions in patients treated with hemodialysis. Clinical symptoms and signs of aluminum toxicity include hypercalcemia, anemia, vitamin D refractory osteodystrophy, and a dialysis encephalopathy. Bone pain, pathological fractures, and proximal myopathy may occur. Aluminum has also been suggested as an etiology of several neurodegenerative diseases such as Alzheimer senile and pre-senile dementia, as well amyotrophic sclerosis. Despite this, the most recent investigations have failed to confirm this hypothesis. A study in man has verified a number of possible deleterious interactions of aluminum salts with phosphorous metabolism, especially in long-term ingestion of aluminum-containing antacids. It has been suggested that aluminum exposure is a risk factor for the development or acceleration of onset of Alzheimer disease (AD) in humans. The world health organization has completed a meta-analysis of 20 epidemiological studies done to test the hypothesis that aluminum in drinking-water is a risk factor for Alzheimer disease. Six studies on populations in Norway were considered of sufficiently high quality to meet the general criteria for exposure and outcome assessment and the adjustment for at least some confounding variables. Of six studies that examined the relationship between aluminum in drinking- water and dementia, three found a positive relationship, but three did not. However, each of the studies had significant deficiencies in the study design (e.g. ecological exposure assessment; failure to consider aluminum exposure from all sources and to control for important confounders, such as education, socioeconomic status, and family history; the use of surrogate outcome measures for AD; and selection bias). In general, the relative risks determined were less than 2, with large confidence intervals, when the total aluminum concentration in drinking-water was 0.1 mg/L or higher. Due to the pathogenesis of AD and knowledge obtained from studies, it was concluded that the present epidemiological evidence does not support a causal association between AD and aluminum in drinking-water. In addition to the epidemiological studies that examined the relationship between AD and aluminum in drinking-water, two studies studied cognitive dysfunction in elderly populations in relation to the levels of aluminum in drinking water. The results proved conflicting. A study of 800 male subjects, age 80-89, drinking water containing aluminum concentrations up to 98 μg/L found no relationship. The second study used “any evidence of mental impairment” as an outcome measure and found a relative risk of 1.72 at aluminum drinking-water concentrations above 85 μg/L in 250 males. Such data are insufficient to show that aluminum is a cause of cognitive impairment in the elderly. **Note on possible risk of breast cancer** Widespread concern has been raised regarding the exposure to aluminum in deodorant/antiperspirant products, with inconclusive results,,,. Results from a more recent case-control study suggest an association between underarm cosmetic use and aluminum concentration in breast tissue and breast cancer. The observed association of underarm cosmetic use with breast cancer was, however, limited to women who report using the products multiple times a day before age of 30.

... Aluminum was added to the freshwater tanks as aluminum sulfate and the pH of the tank was adjusted slowly as necessary to avoid localization of the acid. The tanks were then allowed to equilibrate and 20 fish /golden shiners/ were placed in each tank. At pH 4.5 and 5.0 + 100 ppm aluminum, all fish died within a few hr. With total aluminum concn of 10 ppm and 100 ppm and pH 4.5 and 5.0, it appeared that the aluminum and the acid had a synergistic effect. Visual inspection of the fish showed that the aluminum interacted with the gills, which may have caused suffocation. It is possible that some chemical forms of aluminum are more toxic than others. Suspended clay (aluminum silicate) does not appear to be toxic, but in acid solution, aluminum ion is released, which may be toxic. ...|Four cultivars of ryegrass (Lolium multiflorum Lam. cvs. Gulf, Marshall, Urbana, and Wilo) were grown in nutrient solution (pH 4.2 at 0 and 74 uM aluminum). Following a 30 min equilibration period after seeds were exposed to aluminum on day 10 after germination, total and monomeric aluminum concn were 78 + or - 6 and 69 + or - 5 um, respectively. Cations were desorbed from the Donnan free space of roots of 15, 23, and 35 day old plants using barium chloride, barium chloride triethanolamine, ammonium acetate, and potassium chloride. (The ability of desorbents to displace cations varied widely for the desorbent effect). Barium chloride triethanolamine showed the greatest ability to displace aluminum cations from the Donnan free space, while NH4+ did not displace detectable amounts of aluminum +3. The amounts of aluminum +3 displaced by barium +2 and potassium +1 from aluminum treated roots were larger in younger than in older roots. Aluminum considerably decr the amount of desorbed divalent cations (calcium +2, magnesium +2) and increased the amount of desorbed potassium +1 and sodium +1. /Aluminum sulfate octadecahydrate/

/BIRDS and MAMMALS/ ... The effects of aluminum or acid on growth-related hormones were compared in mallard ducklings: growth hormone, insulin-like growth factor, and insulin-like growth factor binding proteins (IGFBPs). Birds received two levels of acid: sulfuric acid (0.056 or 0.277 moles sulfate per kg) or aluminum sulfate (0.1 or 0.5% aluminum; 0.056 or 0.277 moles sulfate per kg). Two sodium sulfate (0.056 or 0.277 moles sulfate per kg) treatment groups were added as additional controls, and a group was given control diet ad libitum. Ducklings were fed the test diets for 15 days. In addition, there were pair-fed controls to the acid and aluminum diets. Growth as indicated by body weight, average daily gain, and tibiotarsus length was reduced (p < 0.05) in ducklings on the high aluminum diet compared to those fed control diets.|/AQUATIC SPECIES/ The acute and chronic toxicity of aluminum sulfate to Ceriodaphnia dubia larvae and juveniles were examined in static renewal tests. The live offspring of Ceriodaphnia dubia in seven day test ranged from 34.2 to 8.2 for 0 to 100% effluent, respectively. Delayed brood release and significant reductions in Ceriodaphnia dubia reproduction observed in 100% effluent were likely due to the combined effects of reductions in pH and dissolved oxygen concentration, physical stress due to high levels of suspended solids, and possibly, the presence of aqueous aluminum.|/AQUATIC SPECIES/ ...Freshwater benthic algal populations /were exposed/ to aluminium concentrations of 50, 100 and 500 ug Al/L (as aluminium sulfate) at pH 4.8 in artificial streams. During the 28-day test, aluminium in acidified water inhibited the abundance of diatoms and cyanobacteria (blue-green algae) more than the acidity alone. Aluminium decreased chlorophyll abundance beyond the effects of acidity alone at 500 ug/L.|/AQUATIC SPECIES/ The egg and fry stages of lake trout (Salvelinus namaycush) and brook trout (Salvelinus fontinalis) were exposed to 0, 50, 100, 200, or 300 ug/L aluminum (as aluminum sulfate) in soft water at various pH levels (3.8 to 6.0). For both fry stages of brook trout, survival at pH 4.8 was reduced when 200 ug/L were added and at pH 4.2 survival was lower at all aluminum concentrations compared to controls. Mortality was not confined to the exposure period and often continued after transfer to control water following short term exposure of eggs and fry. In general an additional 15 to 30% of cleavage eggs died following exposure. In another experiment, groups of 10 swim-up fry lake and brook trout were exposed to 0, 100, 300, and 1000 ug/L aluminum for 6, 24, 50, or 120 hr at pH 3.8, 4.0, 4.2, or 4.4. Single episodes of exposure required extreme combinations of pH, aluminum or time to produce significant mortality of fry. At pH 3.8, mortality of brook trout was mostly confined to the post exposure period and addition of aluminum improved survival over that in controls. Aluminum lethality of brook trout was apparent within 50 hr at pH 4.0 and post-exposure mortality was confined to aluminum treatments. For brook trout, addition of 1000 ug/L aluminum produced substantial mortality following 24 hr at pH 4.4 (approx 25% at 24 hr, to 95% at 120 hr).|For more Ecotoxicity Excerpts (Complete) data for ALUMINUM SULFATE (9 total), please visit the HSDB record page.

Drug Information

Solutions containing 5 to 10% aluminum sulfate have been used as local applications to ulcers and to arrest foul discharges from mucous surfaces. Aluminum sulfate is also used in the preparation of aluminum acetate ear drops. It is often purchased over the counter and is available in solid stick or powder form for minor cuts and abrasions after shaving,. Aluminum sulfate is also used as an adjuvant in vaccines.

Aluminum sulfate has an action similar to that of alum but is more stringent. A saturated solution is employed as a mild caustic. Solutions containing 5 to 10% have been used as local applications to ulcers and to arrest foul discharges from mucous surfaces. Aluminium sulfate is also used in the preparation of aluminium acetate ear drops.|Some aluminum compounds are employed therapeutically, eg, aluminum hydroxide is one component of the antacids recommended in the treatment of stomach ulcers and gastritis. Large doses of aluminum hydroxide (in the order of grams) are prescribed for patients who, as a result of renal dysfunction, have high blood phosphate levels. Aluminum acetotartrate in solution is used in the treatment of sores and for other dermatological purposes. The solution inhibits bacteria and has astringent properties. Aluminum chloride hexahydrate is very commonly used in deodorants, and a solution of aluminum sulfate has been tried without significant success against stings of fire ants. /Aluminum and its salts/|/The following aluminum salts are used in the various drug classes./ (1) Antacids: aluminum; dihydroxyaluminum acetate; aluminum carbonate; aluminum oxide; bismuth aluminate; Magaldrate; dihydroxyaluminum aminoacetate; and dihydroxyaluminum sodium carbonate. (2) Internal analgesics (buffered aspirins): aluminum hydroxide and aluminum glycinate. (3) Antidiarrheals: Kaolin; aluminum magnesium silicate; and Attapulgite. (4) Douches: ammonium aluminum sulfate (5- 16%); potassium aluminum sulfate; and Alum (12%). (5) Antiulcerative: aluminum sucrose sufate. /Aluminum salts, from table/|...Batch coagulation treatments of water samples spiked with Qbeta, MS2, T4, and P1 viruses were conducted with four different aluminum coagulants. The total infectious virus concentration in the suspension of floc particles that eventually formed by dosing with coagulant was measured after the floc particles were dissolved by raising the pH with an alkaline beef extract solution. The virus concentrations were extremely reduced after the water samples were dosed with aluminum coagulants. Viruses mixed with and adsorbed onto preformed aluminum hydroxide floc were, however, completely recovered after the floc dissolution. These results indicated that the aluminum coagulation process inactivates viruses.

Aluminum sulfate may be used as a deodorant, as well as an astringent. Aluminum sulfate is also known as an astringent. Astringents are substances that cause contraction or shrinkage of tissues and that dry up secretion. Used as a post-shaving treatment, it can eliminate bleeding from superficial wounds,. It has also shown in vitro anti-microbial activity.

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity. (See all compounds classified as Adjuvants, Immunologic.)

The degree of aluminum absorption depends on a number of factors, such as the aluminum salt ingested, pH (for aluminum speciation and solubility), bioavailability, as well as dietary conditions. These facts should be taken into consideration during tissue dosimetry and response assessment to aluminum sulfate. It can be concluded that the use of currently available animal studies to develop a guideline value is inappropriate at this time due to the above specific toxicokinetic/dynamic factors that may affect results.|Aluminum is excreted predominantly via the kidneys and therefore may accumulate in patients with renal failure. About 2% is excreted in bile.|Aluminium which is absorbed is located primarily in the heart, spleen, and bone.|In mammals GI absorption of ingested aluminum is poor due to transformation of aluminum salts into insoluble aluminum phosphate (AlPO4) in digestive tract, brought about by pH changes and presence of phosphate in diet. At higher doses, such as 200 mg aluminum/kg as aluminum sulfate, intestinal absorption is about 10% in rats ... .|... No increases in urinary excretion of aluminum or in aluminum deposition in organs of rats when twice normal aluminum concentration was given as ... sulfate in food. When concentration was increased to about 15 times normal, both urinary excretion and organ deposition were enhanced.|In rats retention of aluminum in bone, liver, and testes ... increased with large ingested doses such as 200 mg aluminum/kg in the form of aluminum sulfate ...

Excretion is mainly fecal, representing both unabsorbed ... and aluminum excreted into digestive tract from liver via bile.|Spring wheat plants (Triticum aestivum (L.) cvs. Kadt and WW 20299) were grown in culture and exposed to aluminum as aluminum sulfate. Aluminum uptake by roots of 9-day old plants at pH= 4.1 during 2 hr (initial uptake) could be divided into a free diffusible component and a bound fraction which was non-exchangeable with calcium. Two types of aluminum binding sites were identified: one insensitive to low temp (2 °C) and one existing only at 22 °C. At 2 °C and 200 uM aluminum, uptake reached approx 1.2 umol aluminum/g fresh wt within 50 min and remained at this level. At 22 °C, aluminum uptake did not reach equilibrium within 150 min and was characterized by a rapid uptake (0.50 umol aluminum/g fresh wt) for less than 20 min, followed by another phase at 0.19 umol Aluminum/g fresh wt/hr. The initial uptake of aluminum increased under conditions which favored leakage of phosphorus from the roots; uptake of aluminum from 50 uM aluminum was about twice as high in high phosphorus plants compared to low phosphorus plants. With 1X10-4 dinitrophenol present in the external soln, aluminum uptake increased by approx 70% at 150 and 250 uM aluminum and by approx 25% at 50 uM aluminum in both cultivars.|For more Absorption, Distribution and Excretion (Complete) data for ALUMINUM SULFATE (9 total), please visit the HSDB record page.

Numerous studies have actually shown that the rate of aluminum clearance in the blood decreases with time following aluminum ingestion, and therefore a single elimination half-life (t1⁄2) cannot depict the whole-body elimination of aluminum.

When used as a deodorant, the volume of sweat produced is reduced by narrowing sweat ducts. The inhibition of body odor causing bacteria is another important strategy for deodorization. By inhibiting or deactivating odor-producing bacteria, there is little to none metabolism of sweat components thus decreasing the occurrence of body odor. Recent studies suggest that the active binding of alum to the membranes of dendritic cells (DCs) result in alteration of lipid membranes structures as a key process in alum's adjuvant effect in vaccines. As new adjuvants are being developed, alum may remain as an ingredient of adjuvant combinations, or it may eventually be supplemented by other agents that more effectively provide depot and local inflammatory responses to accentuate host immune responses.|...Glioma (C-6) and neuroblastoma (NBP2) cells were utilized to assess early changes in oxidative parameters consequent to a 48-hr exposure to aluminum sulfate. A 500-uM concentration of this salt produced a significant increase in reactive oxygen species (ROS) production and a significant decrease in glutathione (GSH) content in glioma cells. However, the same concentration of the aluminum salt did not lead to any significant changes in the neuroblastoma cells. Mitochondrial respiratory activity in glioma cells was also found to be significantly higher in the aluminum treated cells. As judged by morin-metal complex formation, aluminum can enter glioma cells much more readily than neuroblastoma cells.|... The aim of this work was to assess by in vivo brain microdialysis whether chronic administration of aluminium in the drinking water (2.5% aluminium sulfate) also impairs the glutamate-nitric oxide-cGMP pathway in the cerebellum of rats in vivo. Chronic exposure to aluminium reduced NMDA-induced increase of extracellular cGMP by ca 50%. The increase in extracellular cGMP induced by the nitric oxide generating agent S-nitroso-N-acetylpenicillamine was higher (240%) in rats treated with aluminium than in controls. Immunoblotting experiments showed that aluminium reduced the cerebellar content of calmodulin and nitric oxide synthase by 34 and 15%, respectively. Basal activity of soluble guanylate cyclase was decreased by 66% in aluminium-treated rats, while the activity after stimulation with S-nitroso-N-acetylpenicillamine was similar to controls. Basal cGMP in the cerebellar extracellular space was decreased by 50% in aluminium-treated rats. These results indicate that chronic exposure to aluminium reduces the basal activity of guanylate cyclase and impairs the glutamate-nitric oxide-cGMP pathway in the animal in vivo.|Aluminum salts have been shown to stimulate (3)H-thymidine incorporation in primary cultures of bovine brain microvessel endothelial cells. Aluminum chloride or sulfate salts in concentrations between 0.01 to 100 uM were, in general, most effective in stimulating thymidine uptake by bovine brain microvessel endothelial cells with maximal efects observed after a 24 hr exposure to the metal. Concentration of aluminum salts greater than 100 uM inhibited thymidine incorporation. Cell numbers were not affected by exposure to concentrations of the aluminum salts less than approx 100 uM. Concentrations producing half maximal stimulation of bovine brain misrovessel endothelial cell thymidine incorporation were approx, 0.3 uM and 0.5 uM, for aluminum chloride and aluminum sulfate, respectively. These findings indicate that bovine brain microvessel endothelial cells are sensitive to lower concentrations of aluminum salts than other mammalian cell types. Hydroxyurea completely inhibited thymidine incorporation into bovine brain microvessel endothelial cells in the presence and absence of aluminum suggesting that thymidine incorporation into bovine brain microvessel endothelial cells is representative of DNA synthesis. Endothelial cell growth factor stimulated both measured DNA synthesis and bovine brain microvessel endothelial cell numbers in the primary culture system. Aluminum had only slight effects on DNA synthesis in edothelial cell growth factor stimulated bovine brain microvessel endothelial cells. In contrast to endothelial cell growth factor, aluminum then, appears to provide a stimulus for DNA synthesis but not subsequent mitosis in bovine brain microvessel endothelial cells. Results from this study are consistent with previous studies in other cell types and with current knowkedge of the effects of aluminum on the blood brain barrier in vivo. /Aluminum salts/

/HUMAN EXPOSURE STUDIES/ ...The exposures of workers engaged in the synthesis of the simple aluminum sulfate salt /were reported/. ...Exposures were poorly controlled as a result of start-up problems, and atmospheric exposure concentrations ranged form 0-53 mg/cu m as dusts with 25-30% in the respirable range. The employees manifested nocturnal wheezing and breathlessness characteristic of occupational asthma. This reversible airway obstruction persisted despite 2-5 years of nonexposure (mean=41 months) in 11 of the 19 workers initially affected. The similarity of these cases of reversible obstructive airway disease or occupational asthma cases to those seen in aluminum smelters is noteworthy.

Aluminum sulfate Use and Manufacturing

Methods of Manufacturing

1. Sulfuric acid method is crushing the bauxite to a certain size, then going into reaction kettle to react with sulfuric acid. The reaction solution was settled, and neutralized to neutral or slightly alkaline by adding sulfuric acid. And then it's concentrated to about 115 ℃, after cooling and crushing to produce the finished product.The reaction equation is as follows: It's obtained by the filtering and recrystallization of aluminum hydroxide (or pure kaolin and bauxite) with sulfuric acid. 2. The hydrated aluminium sulfate crystal formed by the crystallization of the acid solution is slowly heated, and the solution is gradually dehydrated. Finally, the temperature rises to 350℃ and anhydrous aluminum sulfate is completely dehydrated.3. With bauxite and sulfuric acid as the main raw material, through the steps of preparation as below:

Uses
