Characteristics and Application :

Potassium sorbate is the potassium salt of sorbic acid. Its primary use is as a food preservative.Potassium sorbate is effective in a variety of applications including food, wine, and personal care.

Sorbic Acid (also called chemically 2,4-Hexadienoic acid ), a white crystalline powder or granule form  for dust free, is an unsaturated fatty acid which has two double bonds in conjugation that is, two double bonds separated only by one single bond. It and its salts (potassium sorbate, calcium sorbate ; its salts are used according to differences in solubility.) are used as preservatives in wide range of food products as well as in their packaging materials, since they are characterized by their broad effectiveness to inhibit molds, yeast, and many bacteria growth in food. Potassium sorbate, white to slightly yellow crystalline powder, is the potassium salt of sorbic acid and is much more soluble in water than the acid. Potassium sorbate will releases back sorbic acid if dissolved in water. It is effective up to pH 6.5 but effectiveness increases as the pH decreases. The lower the pH value of the product the lower amount of Sorbic Acid or Potassium Sorbate is needed for preservation.

Potassium Sorbate is used as a mold, bacterial and yeast inhibitor and as a fungistatic agent in foods. It is also used in cosmetics, pharmaceutical, tobacco and flavoring products. In wines, it is to prevent the secondary fermentation of residual sugar. It is used in coating to improve gloss. It is used as an intermediate to manufacture plasticizers and lubricants.. It is used as an additive in rubber industry to improve milling characteristics.

Uses :

Potassium sorbate has reported used in the following product types: facial moisturizer/treatment; moisturizer; anti-aging; body wash/cleanser; facial cleanser; conditioner; shampoo; sunscreen spf 15 and above; styling gel/lotion; around-eye cream.
