    Specialty Drugs

    Zinc oxide

    Mainly used in rubber or cable industry as a reinforcing agent and activator, as a colorant and filler for white glue, and as a vulcanizing agent in neoprene; used as a fine desulfurization of raw gas in the fertilizer industry; Used as white pigment, rubber vulcanization activator, reinforcing agent, organic synthesis catalyst, desulfurizer, used for electrostatic photocopying, pharmaceuticals, etc.; used for desulfurization of synthetic ammonia, petroleum and natural gas chemical raw materials

    Sodium Nitrite

    Component of heat-transfer salts, chemical in metal treatment & finishing operations, component of detinning solution & multipurpose greases, agent for recovery of tin from scrap.

    Ethylenediaminetetraacetic Acid (EDTA)

    Ethylenediaminetetraacetate (EDTA) is a sequestrant and chelating agent that functions in water but not in fats and oils. It is used to control the reaction of trace metals with some organic and inorganic components to prevent deterioration of color, texture, and development of precipitates, as well as to prevent oxidation which results in rancidity. The reactive sites of the metal ions are blocked, which prevents their normal reactions. The most common interfering metal ions in food products are iron and copper. It can be used in combination with the antioxidants bht and propyl gallate. It is used in margarine, mayonnaise, and spreads to prevent the vegetable oil from going rancid. It is used in canned corn prior to retorting to prevent discoloration caused by trace quantities of copper, iron, and chromium. It also inhibits copper-catalyzed oxidation of ascorbic acid. It occurs as disodium calcium and disodium dihydrogen . Its use is approved in specified foods, with an average usage level being in the range of 100–300 ppm.


    Hydroquinone, also benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C6H4(OH)2. Its chemical structure, shown in the table at right, features two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid. Substituted derivatives of this parent compound are also referred to as hydroquinones. The name "hydroquinone" was coined by Friedrich Wöhler in 1843.

    Trisodium Phosphate

    A water-soluble reagent widely used as a cleaning agent and often used in the formulation of various buffers. As a quality improver, it has the functions of increasing the complex metal ions, pH value, and increasing ionic strength of food, thereby improving the binding force and water holding capacity of food. China stipulates that it can be used for cheese, the maximum use amount is 5g/kg; the maximum use amount is 3.0g/kg in Western-style ham, meat, fish, shrimp and crab; the maximum use amount is 0.5g in canned food, juice, beverages and dairy products /k. Used as analytical reagent and water softener, and also used in the purification of sugar; used as water softener and detergent, boiler scale inhibitor, color fixing agent during printing and dyeing, mercerizing enhancer for fabrics, metal corrosion inhibitor or rust inhibitor . Used as flux and decolorizing agent in enamel industry. It is used as a degreasing agent and degumming agent in the leather industry. Used as water softener, boiler descaling agent, metal rust inhibitor, sugar juice purifier, etc.

    Aluminium Chloride

    Aluminum chloride has extensive commercial applications. It is used primarily in the electrolytic production of aluminum. Another major use involves its catalytic applications in many organic reactions, including Friedel-Crafts alkylation, polymerization, isomerization, hydrocracking, oxidation, decarboxylation, and dehydrogenation. It is also used in the production of rare earth chlorides, electroplating of aluminum and in many metal finishing and metallurgical operations.

    Turpentine Oil

    It has unique chemical activity. It is a chemical raw material for paint, synthetic camphor, terpineol, synthetic fragrance, synthetic resin, medicine, organic chemical industry and so on.

    Sulfur is an essential element for all life, and is widely used in biochemical processes such as metabolic reactions. Elemental sulfur is mainly used as a precursor to other chemicals such as sulfuric acid. Sulfur is increasingly used as a component of fertilizers. It can be used as an ingredient of Pesticide as well.

    Aluminum sulfate

    Aluminum sulfate is mainly used as a purifying agent for turbid water, but also as a precipitant, fixing agent, filler, etc. Used in cosmetics as an antiperspirant cosmetic raw material (astringent). In addition, aluminum sulfate can also be used as a finishing agent in the paper industry (gluing turpentine to make the color attached to the paper surface); leather tanning agent; mordant; water purifier (flocculant, the resulting aluminum hydroxide flocculant can be suspended in water The particles are coated to promote rapid sedimentation and separation); internal retention agent of foam fire extinguishers (external retention agent is sodium bicarbonate, which generates carbon dioxide after reaction); raw materials for alum and aluminum white; petroleum decolorization and deodorant; pharmaceutical raw materials; Used as food curing agent (excipient); used to remove impurities from grease, water, etc.; stabilizer for albumin pasteurization; raw material for lake; sewage treatment agent; raw material for waterproof concrete; raw material for fireproof cloth.
