  • Fragrance in a w/s emulsion

    Posted by NorseMountain on February 5, 2024 at 2:54 pm

    I’m working on an overnight face mask using a Dimethicone/bentonite clay, peg-meadowfoam esters and water, basically (with glucono delta lactone, butylene glycol, phenoxyethanol, sodium chloride, HLA, and some botanicals in glycerine). It doesn’t smell great, but I’m worried about adding an oil based fragrance because I’ve had these creams separate if I mess with them. I’m not very experienced with silicones, so forgive me if this is a stupid question. It doesn’t have any other straight up fats.

    Thanks for any advice for this noob.

    If you are certain this is a w/Si invert emulsion then premix your fragrance oil into an ester carrier that is miscible with cyclomethicone, then add to your batch. There are several that work, C12-15 alkyl benzoate being most prominent.
