Sodium Cocoyl Methyl Isethionate
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 Isethionate) is similar to SLMI.
In the video below we are making a sulfate-free shampoo with Innospec’s SCMI and CAPB as the surfactants. 1.4% sodium chloride was included to thicken. As with SLMI, adding a chelator helps clarity.
The video (except the last static shot), was filmed in July 2019 and at that point no DIY suppliers were selling SCMI. Windy Point Soap in Canada have now brought it in. Give it a try and let us know your thoughts!
