What it is
Acetamide MEA is the monoethanolamine amide of acetic acid, a water-soluble ingredient used primarily as a humectant. It draws water to the skin surface and can improve the smoothness and suppleness of a formulation. In sunscreens it supports a moisturized feel and can aid in maintaining hydration of the applied film.
Safety & warnings
Acetamide MEA is used as a conditioning humectant in leave-on and rinse-off products at customary use levels. As an ethanolamine-derived material, it should be formulated to avoid conditions favoring nitrosamine formation, which is a manufacturing and formulation consideration; it is not a recognized fragrance allergen.
Origin & sourcing
Synthetic; produced by reacting acetic acid or its derivatives with monoethanolamine.
