Phytantriol is an aliphatic alcohol used in cosmetic products and as a food additive.[1][2] At room temperature it is a viscous liquid that is colourless to light yellow and with a sweetish odour.[3][1]
Phytantriol is prepared by oxidizing isophytol in formic acid, hydrolysis of the product with an inorganic base, and isolation.[1]
As a cosmetic ingredient, phytantriol functions to increase moisture retention in skin and hair and helps vitamins and amino acids penetrate.[4] As of 2002 it is found in about 100 cosmetic products, such as hair conditioners, shampoos, and hair tonics, in concentrations from 0.0002% to 1%.[1]
Phytantriol is an amphiphile that is the second most used in making cubosomes.[5]
