SCI (Sodium Cocoyl Isethionate) is a commonly used anionic, sulfate-free surfactant, loved by syndet makers for it’s mildness and creamy lather. However, due to its poor water solubility it is usually replaced with SLMI (Sodium Lauryl Methyl Isethionate) in liquid products. SCMI (Sodium Cocoyl Methyl …
I love this handy chart from Innospec’s presentation: “Formulating High Performance Sulfate-Free Cleansing Products”. As you can see, surfactants have a working pH range. Some surfactants can hydrolyze at a low pH (SCI, Iselux, Sulfosuccinate). As most surfactants are diluted, we have a handy …
In this article we examine solubilizers, how to use them and review the performance of a selection of “natural” solubilizers. We are frequently asked how solubilizers differ from emulsifiers. Solubilizers and high HLB emulsifiers are both surfactants which help disperse oils in water. Solubilizers are more …
Surfactant Active Matter Calculator Shower gel, shampoo and face cleansers usually contain at least two surfactants to make the formulation milder and more effective. As surfactants sold by ingredient suppliers are diluted it can be challenging to know exactly how much surfactant is in a …
