Cetearyl Behenate

What is Cetearyl Behenate?

Cetearyl Behenate is an ester derived from cetearyl alcohol, a blend of cetyl and stearyl alcohols typically sourced from coconut or palm, and behenic acid, a long-chain fatty acid from rapeseed or other vegetable oils. This waxy, white solid appears in oil-in-water emulsions like moisturizers, body creams, and hair conditioners. It functions by melting at skin temperature to lubricate the surface, improving product spreadability and stability. As a co-emulsifier, it helps blend oil and water phases, preventing separation. Its high melting point adds thickness and a creamy feel, while its occlusive nature reduces water evaporation from the skin barrier without clogging pores.
