About this ingredient
Isopropyl Myristate (IPM) is a synthetic ester of isopropanol and myristic acid (C14). Clear oily non-sticky liquid with a light dry finish.

Provides silky slip, removes the oily afterfeel from creams, speeds product spreading. Often as solvent for retinoids and UV filters. In Spain in Babaria, Eucerin, Bioderma formulas, men's shaving products. Comedogenicity. IPM topped comedogenic ingredient lists after early rabbit ear studies (Fulton 1972). Newer human acne studies (Mills 1992) showed comedogenicity on human skin is lower than rabbit models – but use cautiously in acne-prone patients. On oily skin in some patients it worsens pore clogging and comedonal acne. Safety. CIR rated isopropyl myristate safe at cosmetic concentrations (1982, re-evaluated 2018). EU SCCS has set no restrictions. Irritation and sensitization are rare. Pregnancy and lactation – safe topically. Suitable for dry and normal skin, no restrictions on body. With acne-prone facial skin prefer non-comedogenic emollients (squalane, capric/caprylic triglyceride).
