What is Trilaurin?

Trilaurin, also known as glyceryl trilaurate, is a triglyceride formed by esterifying three lauric acid molecules to a glycerol molecule. Sourced mainly from coconut or palm kernel oils, it exists as a white, odorless, waxy solid. In cosmetic formulations like creams, lotions, and balms, it serves primarily as an emollient and skin conditioner. It works by depositing a thin lipid film on the skin's surface, which helps fill in irregularities for a smoother feel and reduces transepidermal water loss. Additionally, its viscosity-modifying action stabilizes emulsions and improves spreadability, while solvent capabilities dissolve lipophilic actives for even distribution. This ingredient integrates well into oil-based and anhydrous products, supporting overall formulation performance and skin comfort.

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.
Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.

Benefits
