Acetyl Ethylhexyl Polyhydroxystearate
What is Acetyl Ethylhexyl Polyhydroxystearate?
Acetyl Ethylhexyl Polyhydroxystearate is a synthetic emollient and viscosity-increasing agent derived from polyhydroxystearic acid esterified with acetyl and ethylhexyl groups. It functions primarily as a thickener in cosmetic formulations, providing a smooth, non-greasy texture and enhancing the spreadability of products like creams, lotions, and sunscreens. This ingredient helps stabilize emulsions and improves the sensory feel on the skin without adding tackiness.
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.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
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.
