Optimal crystallization helps sustain beauty

Oleic acid is an important mono-unsaturated fatty acid that occurs in vegetable oils. It is widely used as a moisturizer in cosmetic formulations of creams, bath additives, shampoos, conditioners, lipsticks and hair dyes. The physical properties of oleic acid are influenced by the presence of isomers with different geometry, double bond position and degree of unsaturation. In the pure state, oleic acid is a colorless liquid that readily oxidizes upon exposure to air. One useful property often measured for quality control purposes is the cloud point. This is the temperature at which the oleic acid sample first becomes cloudy. It corresponds to the initial stages of crystallization.
