GENERAL DESCRIPTION & EXTERNAL LINKS
Fatty Acid Esters are used as raw material of emulsifiers or oiling agents for foods, spin finishes and textiles; lubricants for plastics;  Paint and ink additives; surfactants and base materials for perfumery. They are used as solvents or cosolvents, oil carrier in agricultural industry.

Why is it used in cosmetics and personal care products?: Stearate esters act primarily as lubricants on the skin¡¯s surface, which gives the skin a soft and smooth appearance. Butyl Stearate also decreases the thickness of lipsticks, thereby lessening the drag on lips, and imparts water repelling characteristics to nail polishes. Butyl Stearate and Isopropyl Stearate dry to form a thin coating on the skin. Isocetyl Stearate can also be used to dissolve other substances, usually liquids.

Stearic acid comes from many animal and vegetable fats and oils. It is a waxy solid. Its name comes from the Greek word stéar (genitive: stéatos), which means tallow. Stearic acid is useful as an ingredient in making candles, soaps, plastics, oil pastels and cosmetics, and for softening rubber. Stearic acid is used to harden soaps, particularly those made with vegetable oil. Fatty acids are a carboxylic acid with a long unbranched aliphatic tail (chain), which is either saturated or unsaturated. Fatty acids derived from natural fats and oils may be assumed to have at least 8 carbon atoms. Most of the natural fatty acids have an even number of carbon atoms, because their biosynthesis involves acetyl-CoA, a coenzyme carrying a two-carbon-atom group...
