About this ingredient
Triethylhexanoin is a synthetic ester of glycerol and 2-ethylhexanoic acid. Liquid, odourless, with a light slippery texture. It replaced mineral oil and cyclic silicones in many clean formulas after the 2010s. Mechanism. Ester emollient – fills intercorneocyte spaces, smooths skin, leaves a thin non-greasy finish. Dissolves UV filters well (especially octocrylene and avobenzone) and works as a 'noseyный' carrier in sunscreens. Oxidatively stable – does not degrade with heat and UV. Where applied. Sunscreens (very common in Heliocare 360, Isdin Fotoultra, La Roche-Posay Anthelios Invisible Fluid), foundations, primers, light serums and creams, products for oily skin. Effective at 5-30%. Evidence base. As a functional ingredient. BASF studies (manufacturer of Cetiol 868, the trade name of triethylhexanoin) show improved UV-filter penetration and extended photostability. Doesn't treat the skin but makes the formula work better. Safety. CIR confirmed safety in 2008. Non-sensitising, non-comedogenic (rating 0). Replacement for mineral oil and silicones for clean-positioned brands. Pregnancy and lactation – safe. Usable in sunscreens and creams without restrictions.
