  • water soluble powders in oil stick??

    Posted by natiyo123 on July 5, 2022 at 12:49 am

    So im really curious about what happens when you disperse water soluble powders in an oil/wax stick??? for example citric acid, lactic acid, zinc lactate ,etc… 

    are they “Inactivated” ?? meaning because theyre covered with the oils/waxes theyre no longer soluble and therefore no longer active? if the purpose was to use them as antimicrobials on the skin

    @natiyo123, water soluble ingredients are not compatible with oil/wax stick.
    If you want a preservative and a chelator, look at what the major brands are using like Burt’s bee if you are making a lip balm.
    Helianthus annuus (sunflower) seed oil, cocos nucifera (coconut) oil, beeswax, ricinus communis (castor) seed oil, natural flavor, lanolin cucmis salivus (cucmber) fruit extract, menthe piperita (peppermint) oil. Theobroma cacao (cocoa) seed butter, butyrospermum pakii (shea) butter, carthamus tinctorius (safflower) seed oil, glycine soja (soybean) oil, tocopherol, citric acid, rebaudioside A, limonene, linalool

    In this formula they have a some water soluble ingredients like lanolin cucmis salivus (cucmber) fruit extract and citric acid probably solubilized in the extract. It must be at a very low percentage.

    I think that is a typo and there is supposed to be a comma after lanolin, … there is no such ingredient as lanolin cucumis salivus (cucumber) fruit extract.

    All the other variants of this line of products have a comma after lanolin.

    yup! Mark is correct, lanolin is an ingredient by itself that is fat soluble.
