C12-18 Acid Triglycerides
What is C12-18 Acid Triglycerides?
C12-18 Acid Triglycerides is a synthetic emollient derived from triglycerides of C12-18 fatty acids, commonly produced by interesterification of vegetable oils or fully hardened vegetable oils. It functions as an occlusive agent and skin conditioner in skincare formulations, helping to soften and smooth the skin by forming a protective barrier that reduces transepidermal water loss. This ingredient is valued for its stability, non-greasy texture, and compatibility in both oil-in-water and water-in-oil emulsions.
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 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.
