What is C18-36 Acid Triglycerides?

C18-36 Acid Triglycerides are synthetic emollients derived from triglycerides of C18-36 fatty acids, designed to mimic natural skin lipids. They function as skin-conditioning agents, providing a non-greasy, smooth feel while improving product spreadability and texture in formulations. Commonly used in moisturizers, creams, and lip products for their occlusive properties that help retain moisture.

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.
Refatting
Replenishes lipids removed during cleansing to improve mildness and reduce tightness, leaving skin or hair feeling less stripped after rinse-off use.
Skin protecting
Forms a barrier to protect skin from external irritants.
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.
