Mild vs Harsh Surfactants
I get confused how a surfactant can be mild but harsh on the skin at the same time. I have played with various surfactants for personal use and I aim to make them mild. What does mild mean and what’s harsh?
I have used mild surfactants and have computed the ASM. However, I get reactions like it’s too drying and skin peeling. For instance, I read that Coco Glucoside is a mild surfactant, but it can be harsh on the skin as non-ionics are good degreasers. CMEA thickens surfactants and reduces the irritation level of anionics but is also a penetration enhancer and disrupts the integrity of the skin. When I make formulations with CMEA, my skin peels a lot. Below is my base formula that I use for shampoos and body wash. Is there anything on the ingredients that could be causing skin peeling? Thanks!
ASM - 12
SLES 70% - 10%
CAPB 30% - 10%
CMEA - 2%
Glycerine - 2%
EDTA 10% - 1%
Polyquat 7 - 2%
Fragrance - 1%
EHGP - 1%
