Sodium Perborate

Sodium perborate serves as a source of active oxygen in many detergents, laundry detergents, cleaning products, and laundry bleaches. It is also present in some tooth bleaching formulas. It is used as a bleaching agent for internal bleaching of a non vital root treated tooth.It has antiseptic properties and can act as a disinfectant. It is also used as a "disappearing" preservative in some brands of eye drops.

Sodium Propanoate

Sodium propanoate is the sodium salt of propionic acid. It is used as a food preservative. It is used primarily as a mold inhibitor in bakery products.

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.

Sorbic Acid FOOD GRADE

Sorbic acid and its mineral salts, such as sodium sorbate, potassium sorbate and calcium sorbate, are antimicrobial agents often used as preservatives in food and drinks to prevent the growth of mold, yeast and fungi. In general the salts are preferred over the acid form because they are more soluble in water. 
The optimal pH for the antimicrobial activity is below pH 6.5 and sorbates are generally used at concentrations of 0.025% to 0.10%. Adding sorbate salts to food will however raise the pH of the food slightly so the pH may need to be adjusted to assure safety. 
Application: 
It is used for food, cosmetic, medical health product and anti-mortify for tobacco. As Unsaturated acid, it also used as resin, aromatics and rubber industry.

Sulfite

Sulfites are compounds that contain the sulfite ion SO32-.Sulfite ion is the conjugate base of bisulfite.It occur naturally in all wines.Sulfites are commonly introduced to arrest fermentation at a desired time, and may also be added to wine as preservatives to prevent spoilage and oxidation at several stages of the winemaking.It is also used as preservatives in dried fruits, preserved radish, and dried potato products.Sulfite content in the blood and urine of babies can be caused by molybdenum cofactor deficiency disease which leads to neurological damage and early death.

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.
