Glyceryl Triacetyl Ricinoleate

What is Glyceryl Triacetyl Ricinoleate?

Glyceryl Triacetyl Ricinoleate is a semi-synthetic ester produced from ricinoleic acid, the main fatty acid in castor oil seeds from Ricinus communis. It appears as a pale yellow, viscous liquid and falls into emollient and conditioning categories for cosmetics, especially anhydrous ones like lipsticks, balms, and oil-based foundations. Chemically, it involves acetylating glyceryl ricinoleate, enhancing its solubility and stability. In formulations, it lubricates skin surfaces for better slip and spreadability, mimicking natural oils without greasiness. As a solvent, it disperses pigments, waxes, and fragrances evenly. Its viscosity-modifying action thickens or thins products for optimal texture, preventing settling in multi-phase systems. This supports long-wear makeup and hair styling aids by improving adhesion and flexibility, contributing to glossy finishes and comfortable wear.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

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.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Softens and smooths skin texture through emollient properties.

Supports skin conditioning for maintained flexibility and hydration retention.

Enhances formulation stability and ease of application as a solvent and thickener.
