“Cocamide MEA?”Here!

SurfactantThickenerPlant

Hasn’t appeared in a scanned product yet.

In personal care

A fatty acid amide derived from coconut oil and ethanolamine, used as a thickener and foam enhancer.

Why it’s used

Added to shampoos and cleansers to boost and stabilize foam, and to thicken the product's texture.

What the evidence says

We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.

Look it up yourself

We would rather point you at the shelf than summarize something you can’t check. These are the same places we search:

  • PubChem — what the substance is, chemically — names, synonyms and structure
  • PubMed — every paper indexed by the US National Library of Medicine that names it

These are starting points, not our findings — we haven’t run them for you. A substance whose name is also an ordinary word (“Heart”, “Alanine”, “Water”) will return papers that are not about the ingredient at all.

Context

This is a rinse-off product ingredient in most uses (shampoos, body washes); CIR's nitrosamine-contamination concern depends on formulation conditions, not on the ingredient itself inherently forming them.
