  • Pearling agent for cream?

    Posted by cossci21 on May 15, 2015 at 5:54 am

    Hello everyone
    I am trying to get a cream to pearl and opacify and trying to find out what ingredient to use?

    The formula has stearic acid and cithrom egms (glycol stearate) which i thought would pearl, so far no luck.

    oil phase
    - ceteth 20 1.5%
    - stearic acid 5%
    - cetearyl alcohol 2%
    - glycol stearate 5%
    - olive oil 4%
    - sunflower oil 5%

    The glycol stearate has helped to opacify the product but not pearl. Is there any agents that can make it pearl immediately? or ideas for %?

    Thanks very much

    Try to use mixture of lauric, myristic, palmitic and stearic acid, set the pH above 7 and wait sometime for the effect to set in. Or use a high percentage of stearic acid, say 15% and very minimal oil, neutralize to pH 8 and you would get the effect in sometime.
