Acetamide Mea

Acetamide MEA is a synthetic compound derived from acetic acid and monoethanolamine. In skincare, it functions as a humectant—meaning it helps attract and bind water to the skin—whilst also serving several cosmetic purposes that improve how a product feels and performs.

Because it can reduce static charge, boost foam stability, and control viscosity, it's often used in cleansers and conditioning products rather than serums or lightweight moisturisers. It appears in approximately 0.1% of skincare formulations, suggesting it's a minor ingredient typically combined with other actives rather than a starring player.

Acetamide MEA works by drawing moisture from the environment and deeper skin layers towards the surface, where it can be retained by the stratum corneum. This humectant action is gentle and supports overall hydration without occlusion.

Its secondary functions—controlling viscosity and stabilising formulations—ensure products perform as intended, which indirectly supports better skin outcomes by allowing other beneficial ingredients to remain stable and effective.

Acetamide MEA is not an ingredient you would select independently; it appears as part of finished formulations. Look for it listed in the INCI declaration if you're checking a product's full composition. Because it's typically a minor ingredient, its presence has little bearing on how you use the product—follow the instructions provided for your specific cleanser or conditioner.
