About
A waxy fatty amide used to thicken formulas and improve texture.
Hexamethylene Sesqui-Hydroxystearamide is a mixture of the mono- and diamides of hexamethylenediamine and Hydroxystearic Acid. Fatty amides are usually used as rheology modifiers and texture agents rather than true actives. Their direct skin hazard is typically low, though they can feel heavy and ingredient-specific human data are often limited.
