    Inorganic Salts

    Sodium Metabisulfite

    Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na2S2O5. The substance is sometimes referred to as disodium (metabisulfite). It is used as a disinfectant, antioxidant and preservative agent.

    Titanium Dioxide

    Component of porcelain enamels & glazes-eg, as opacifier. Used in paint, ink, plastic, rubber, paper, chemical fiber and other industries. Edible white pigment; compatibilizer. Silica and/or alumina are commonly used as dispersion aids. As a food coloring agent, my country stipulates that it can be used in preserved fruit, the maximum use amount is: 10g/kg; in candy coating, the maximum use amount is 2.0g/kg. White inorganic pigment. It is the strongest kind of white pigments, has excellent hiding power and color fastness, and is suitable for opaque white products. The rutile type is especially suitable for plastic products used outdoors, and can give the products good light stability. Anatase is mainly used for indoor products, but it has a slight blue light, high whiteness, large hiding power, strong coloring power and good dispersion. Titanium dioxide is widely used as a pigment for paint, paper, rubber, plastic, enamel, glass, cosmetics, ink, watercolor and oil paint, and can also be used in the manufacture of metallurgy, radio, ceramics, and welding electrodes. In recent years, it has been discovered that nano-sized titanium dioxide has some special uses, such as sunscreen cosmetics, wood protection, food packaging materials, agricultural plastic films, natural and man-made fibers, transparent exterior durable topcoats and effect pigments, and can also be used as high-efficiency Photocatalysts, adsorbents, solid lubricant additives, etc. Used in paint, plastic, rubber and other industries

    Ammonium sulfate

    manufacture of ammonia alum; in the manufacture of H2SO4 to free it from nitrogen oxides; analytical uses; freezing mixtures, flameproofing fabrics and paper; manufacture of viscose silk; tanning, galvanizing iron; in fractionation of proteins.The commercial grade is used as fertilizer.

    Sodium Tripolyphosphate

    Used as a water softener, also used in the candy industry, etc.; as a high-efficiency water softener for cooling water treatment in power stations, rolling stock, boilers and fertilizer plants. It has strong ability to complex Ca2+, 19.5g calcium per 100g can be complexed, and the normal growth process of calcium phosphate and other crystals is destroyed due to the chelation and adsorption and dispersion of SHMP, preventing the formation of calcium phosphate scale. The dosage is 0.5mg/L to prevent the scaling rate from 95% to 100%. Tissue improvers; emulsifiers; buffers; chelating agents; stabilizers. Mainly used for the tenderization of canned ham; canned broad beans soften the skin of tofu. It can also be used as water softener, pH regulator and thickener. It is used as a soap synergist and to prevent the precipitation and blooming of bar soap grease. It has a strong emulsification effect on lubricating oil and fat, and can be used to adjust the Ph value of buffer soap. Water softener for industrial water. Leather pre-tanning agent. Dyeing auxiliary. Used as a dispersant when preparing suspensions in paint, kaolin, magnesium oxide, calcium carbonate and other industries. Drilling mud dispersant. Used as an anti-greasy agent in the paper industry. Sodium tripolyphosphate is used in detergents, as an auxiliary, soap synergist and to prevent bar soap crystallization and blooming, industrial water softener, leather pretanning agent, dyeing auxiliary, oil well digging control agent, paper making Oil stain preventer, effective dispersant for suspension treatment of paint, kaolin, magnesium oxide, calcium carbonate, etc. Food grade sodium tripolyphosphate can be used as a food improver for various fish and meat products and a clarifier for beverages. As a quality improver, it has the functions of increasing the complex metal ions, pH value, and ionic strength of food, thereby improving the binding force and water holding capacity of food. my country stipulates that it can be used in dairy products, fish products, poultry products, ice cream and instant noodles, with a maximum use amount of 5.0g/kg; in cans, fruit juice (flavor) beverages and vegetable protein drinks, the maximum use amount is 1.0g/kg.

    Sodium Sulfide

    1. Used in sulfur dyes, used as reductant, mordant, floatation agent, depilatory for leather, digestion auxiliary in paper-making, and used in textile, pigment and rubber
    2. It is used for H2S therapy, to study its effect on the prevention of diabetes in animals.

    Sodium Hexametaphosphate

    Sodium hexametaphosphate is used in meat products, fish sausages, ham, etc., can improve water holding capacity, increase cohesiveness, and prevent fat oxidation; used in bean paste and soy sauce can prevent discoloration, increase viscosity, shorten fermentation period, and adjust taste ; Used in fruit drinks and refreshing beverages, can increase the juice yield, increase the viscosity, and inhibit the decomposition of vitamin C; used in ice cream can increase the expansion capacity, increase the volume, enhance the emulsification effect, prevent the destruction of the paste, and improve the taste and color; used in milk Products and beverages prevent gel precipitation; adding to beer can clarify liquor and prevent turbidity; used in beans, canned fruits and vegetables, can stabilize natural pigments, and protect food color. In addition, the aqueous solution of sodium hexametaphosphate is sprayed on the cured meat to improve the corrosion resistance.

    Mono Amonium Phosphate

    It is mainly used to prepare compound fertilizers, and can also be directly applied to farmland; as analytical reagents and buffers; in the food industry as leavening agents, dough regulators, yeast foods, brewing fermentation aids, and buffers. Also used as an animal feed additive. It is a high-efficiency nitrogen and phosphorus compound fertilizer. It can be used as a fire retardant for wood, paper and fabric, a dispersant for fiber processing and dye industry, a glaze for enamel, a compounding agent for fire-resistant coatings, an ember extinguisher for matchsticks and candle wicks, and a dry powder fire extinguishing agent. It is also used in printing plate making and pharmaceutical manufacturing. Used as fertilizer, fire retardant, and also used in printing and plate making, medicine and other industries. Prepare buffer and culture medium, and produce flame retardant and dry powder fire extinguishing agent for phosphate, fluorescent powder, wood, paper and fabric. The analytical standard is used for nitrogen determination by Kjeldahl method. After the first opening and use, it is recommended to store with argon or nitrogen.
