Product: Cocamido Monoethanolamide (CMEA)
Rchem Cocamido Monoethanolamide (CMEA) is a high-purity, non-ionic surfactant derived from the reaction of coconut fatty acids with monoethanolamine. Presented as white to off-white flakes or beads, this versatile ingredient is renowned for its exceptional thickening and foam-boosting properties. As a secondary surfactant and viscosity builder, CMEA is a cornerstone in personal care formulations, where it enhances the luxurious texture, stability, and sensory appeal of shampoos, body washes, and other cleansing products.

Frequently Asked Questions:
How does CMEA thicken a shampoo formula?
CMEA thickens through the formation of viscous, rod-like micelles in the surfactant solution. Its molecules insert themselves among the primary surfactant molecules (like SLES), increasing the size and interaction of the micelles, which dramatically increases the viscosity of the entire system.
The key difference is the number of ethanolamine groups. CMEA is the monoethanolamide, while CDEA is the diethanolamide. CDEA is generally a more powerful foam booster and thickener, but CMEA is often preferred for its milder profile and because it does not contain diethanolamine, a substance that has faced some regulatory scrutiny due to nitrosamine concerns.
What is the difference between CMEA and Cocamide DEA (CDEA)?
CMEA is typically added to the heated water phase (around 70-75°C) of the formulation. It requires heat and agitation to melt and disperse properly. The mixture should be stirred until the CMEA is fully dissolved and clear before proceeding with the cooling and addition of other heat-sensitive ingredients.
What is the correct method to incorporate CMEA into a formulation?
Generally, no. CMEA is an opacifier and will impart a pearlescent or opaque appearance to the final product. If a clear formula is desired, alternative thickeners like salts (e.g., Sodium Chloride) or acrylic polymers should be considered.
Can CMEA be used in transparent formulations?
Yes, as a non-ionic surfactant, CMEA is considered mild. It helps to reduce the irritation potential of the primary anionic surfactant system while providing conditioning benefits, making the final formulation gentler on the skin and scalp.
