  • Advice shampoo I made. Shall I add solubiliser?

    Posted by Nyatou on September 26, 2024 at 3:48 pm

    Hi everybody,

    I made a clear shampoo with:

    40% sles

    10 % capb

    0.75% PEHG

    0.25% NaBenz

    0.2 % EDTA

    water qs

    0.4 % fragrance

    pH 4,5


    I have been using for months. However I changed the fragrance and now the shampoo is not longer clear. the color is like skimmed milk. I really don’t mind but at the same time I fear stability or efficacy issues.

    @Nyatou you already HAVE solubilizers in your formula. You need to add that fragrance directly into the CAPB first and mix well, then slowly add the pre-mix into the SLES shampoo while warm (40C). If that doesn’t work, add a PEG ester (e.g. PEG-7 glyceryl cocoate, PEG-40 castor oil) to pre-mix with the CAPB & fragrance. Those will not compromise viscosity or foam.
