Stearic acid (trivial name), cetylacetic or n-octadecanoic acid (eng. Octadecanoic acid), monobasic carboxylic acid of the aliphatic series, which at room temperature has the form of colorless crystals, readily soluble in diethyl ether and insoluble in water. Stearic acid is a saturated fatty acid, one of the most abundant fatty acids in nature. It is included in the form of glycerides in lipids, primarily triglycerides (fats) of animal origin, also in most animal fats and, to a lesser extent, in many vegetable oils. The molecular weight is 248.48 g / mol, the density is 0.94 g / ml. The melting point of stearic acid is 69.6 ° C, and the boiling point is 376.1 ° C.

Application

Stearic acid is a part of pharmaceuticals; used as a component of greases.

In cosmetics, stearic acid is used as a mixture stabilizer and emulsifier in the manufacture of cosmetic creams and lotions, as well as in soap making as a thickener, making the soap hard and matte. In the manufacture of soap, stearic acid salt, which has good detergency, is often used.

Stearic acid is used in the food industry as a food additive - emulsifier, foam stabilizer, glazing agent and antifoam with the index “E570 Fatty acids”. Stearic acid is also used in the manufacture of candles and rubber (to give more plasticity and uniformity), greases and in the manufacture of stearin (usually mixed with palmitic and / or oleic acids).
