  • Sodium Cocoyl Isethionate with Betaine in a cream cleanser

    Posted by Anonymous on June 30, 2020 at 2:53 pm

    Hi there, 

    I hope someone can help me troubleshoot: 
    I absolutely love SCI but I find it extremely notorious to work with. 
    I made a cream cleanser and have 2 issues: 

    1. I melted the SCI in half of my formulae’s water and it turned transparent. But after about 4 minutes, a thin film started forming on this SCI/betaine mix. Is there any reason for this or something I can do to remove the thin film? 

    2. Once the SCI/betaine are melted (with the thin film), I added them into my emulsified cream (my cream was a mix of cocoa butter, olivem1000, almond oil and cetyl alcohol blended in the remaining water). As a result, the cream becomes clumpy and I don’t know why. Are you able to advise? 

    Would it be easier if I added the SCI powder after the cream was made? I could but the last time I did that, I would see white powder traces in the cream. 

    I am looking for some guidance. 

    Regards, 

    Amber

    Hi Amber! I don’t know about the film - maybe add a chelator? As far as the other part goes, I would treat the entire thing as an emulsion. In other words, don’t add the cream, add the water soluble parts; mix the oil parts separately, then add all of them together. Try this and let me know what happens!

    What type of SCI are you working with and what percentages are you using?
