Properties Suppliers
Salicylic Acid

Salicylic Acid is a monohydroxybenzoic acid, a type of phenolic acid and a beta hydroxy acid. This colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. In addition to being a compound that is chemically similar to but not identical to the active component of aspirin, it is probably best known for its use in anti-acne treatments. The salts and esters of salicylic acid are known as salicylates. As with other beta hydroxy acids, salicylic acid is a key ingredient in many skin-care products for the treatment of acne, psoriasis, calluses, corns, keratosis pilaris, and warts. It is used as a food preservative and as an antiseptic in toothpaste.

Properties Suppliers
Sodium Sorbate

Sodium sorbate is the sodium salt of sorbic acid. It is used as a preservative to inhibit the growth of moulds, yeasts and fungi in the food industry.

Properties Suppliers
Sodium Sulfide

Sodium sulfide is primarily used in pulp and paper industry. It is used in water treatment as an oxygen scavenger agent, in the photographic industry to protect developer solutions from oxidation, in textile industry as a bleaching, as a desulfurising and as a dechlorinating agent and in leather trade for the sulfitisation of tanning extracts. It is used in chemical manufacturing as a sulfonation and sulfomethylation agent. It is used in the production of rubber chemicals, sulfur dyes and other chemical compounds. It is used in other applications including ore flotation, oil recovery, food preservative, making dyes, and detergent.

Properties Suppliers
Sulfur Dioxide

Sulfur dioxide is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide unless the sulfur compounds are removed before burning the fuel. Sulfur dioxide is an intermediate in the production of sulfuric acid. It used as a preservative for dried apricots and other dried fruits owing to its antimicrobial properties. As a preservative, it maintains the appearance of the fruit and prevents rotting. Sulfur dioxide is also a good reductant. In the presence of water, sulfur dioxide is able to decolorize substances. Specifically it is a useful reducing bleach for papers and delicate materials such as clothes. Sulfur dioxide is a versatile inert solvent that has been widely used for dissolving highly oxidizing salts. It is also used occasionally as a source of the sulfonyl group in organic synthesis.

Properties Suppliers
sodium sulfite

Sodium sulfite is a soluble sodium salt of sulfurous acid.It is prepared from sulfur dioxide and sodium carbonate or caustic soda.It is also used as a preservative for fruits,meats.It is also used in pulp and paper industry,photographic industry,in the textile industry as a bleaching, desulfurizing and dechlorinating agent and in the leather trade for the sulfitization of tanning extracts.

Properties Suppliers
Calcium Sorbate

Calcium sorbate is the calcium salt of sorbic acid. It is a polyunsaturated fatty acid salt. It is a commonly-used food preservative.

Properties Suppliers
Calcium Sulfite

Calcium sulfite is a chemical compound which is the calcium salt of sulfurous acid. As a food additive it is used as a preservative. It is commonly used in preserving wine, cider, fruit juice, canned fruit and vegetables. Like other metal sulfites, calcium sulfite reacts with acids to produce a calcium salt, sulfur dioxide gas and water. For this reason, calcium sulfite is not a desirable compound in drywall - when humid, it releases sulfur dioxide and carbon dioxide is absorbed to form calcium carbonate.

Properties Suppliers
Erythorbic Acid

Erythorbic acid, formerly known as isoascorbic acid and D-araboascorbic acid, is a stereoisomer of ascorbic acid (vitamin C). It is a vegetable-derived food additive produced from sucrose. It is widely used as an antioxidant in processed foods. The use of erythorbic acid as a food preservative has increased. It is also used as a preservative in cured meats and frozen vegetables.
