TRIISODECYL TRIMELLITATE ●
TL;DR. This ingredient is primarily a rich emollient, pigment dispersant, and film-forming binder in lip, complexion, and sunscreen products. It adds cushion, gloss, and water resistance while helping powders and colorants spread evenly.
What does TRIISODECYL TRIMELLITATE do in a cosmetic formula?
This ingredient is primarily a rich emollient, pigment dispersant, and film-forming binder in lip, complexion, and sunscreen products. It adds cushion, gloss, and water resistance while helping powders and colorants spread evenly.
Is TRIISODECYL TRIMELLITATE clean?
It has a low skin-sensitization profile and is generally viewed as a low-irritation synthetic emollient. Its clean-standard friction comes from petrochemical sourcing and lack of natural-standard fit, not from common allergen or preservative-restriction issues.
Is TRIISODECYL TRIMELLITATE sustainable?
This material is usually made from petrochemical feedstocks. Its bulky, highly branched structure and very low water solubility mean biodegradation is expected to be slower than for simple plant oils, with limited public biodegradability data.
Is TRIISODECYL TRIMELLITATE COSMOS-approved?
This ingredient is not typically permitted under COSMOS natural or organic standards because it is a fully synthetic ester outside the allowed natural-derived ingredient categories. From a Green Chemistry view, it has good product stability but weaker alignment on renewable feedstocks and end-of-life biodegradability.
How does TRIISODECYL TRIMELLITATE work chemically?
The molecule is a high-molecular-weight aromatic triester with three branched C10 alkyl chains, which gives low volatility, very low water solubility, strong pigment wetting, and a glossy, cushioned skin feel. It is often used around 1–30%, with higher levels in anhydrous color cosmetics, and it is more oxidation-stable than unsaturated natural oils while remaining most hydrolytically stable near neutral pH.
