Trilinolein

What is Trilinolein?

Trilinolein is a triglyceride ester where glycerol binds three linoleic acid chains, a polyunsaturated fatty acid extracted from high-linoleic vegetable oils like safflower or sunflower. It falls under emollients and conditioning agents in cosmetics, commonly featured in oil-based items such as lipsticks, balms, and serums. In formulations, it delivers a silky, non-oily barrier resembling skin lipids, boosting spreadability and slip. It dissolves oil-soluble components as a solvent, stabilizes viscosity for smooth dispensing, and replenishes surface lipids in cleansers to minimize stripping. This multifunctionality supports even texture in diverse product types without heaviness.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Refatting
Replenishes lipids removed during cleansing to improve mildness and reduce tightness, leaving skin or hair feeling less stripped after rinse-off use.
Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.

Benefits

Promotes skin softness and smoothness through emollient action.

Controls viscosity for better product stability and application.

Refats skin post-cleansing to reduce dryness feeling.
