Alkyl Benzoate
What is Alkyl Benzoate?
Alkyl Benzoate, most commonly C12-15 Alkyl Benzoate, is an ester derived from benzoic acid and C12-15 alcohols, used as a lightweight emollient and solvent in skincare formulations. It provides a non-greasy, silky feel to products, enhances the spreadability of emulsions, and helps solubilize other ingredients like fragrances and UV filters. Widely utilized in moisturizers, sunscreens, and makeup for its low odor and compatibility with various formulation types.
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.
Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.
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.
