    Hello chemists!

    I’m trying to come up with a gentle, yet effective facial cleanser that’s appropriate for normal/oily skin. It needs to be gentle but also be able to completely remove makeup. Previously I’ve tried a combination of  5 % SCI, 5 % DLSS and 2.5 % Cocamidopropyl betaine but it felt too mild and hardly removed any makeup.

    For my next try, I’m thinking about using 20 % DLSS and 10 % Cocamidopropyl betaine. What are your opinions?

    Is that % active in the formula or % of the raw material?  Also, could you clarify what your acronyms stand for?

    SCI = ?
    DLSS = ?

    I think he is ref to the percentage in formula, sci is sodium cocoyl isothinate and the other one is disodium lauryl sulfosuccinate if i m not wrong.

    Sorry for not being clear. @milliachemist is correct, I am refering to the percentage in formula and SCI is indeed sodium cocoyl isethionate and DLSS is disodium laryl sulfosuccinate.

    Ah.  Well, 20% and 10% seem pretty high but not unreasonable.  You might get an even better product if you used a small amount of SLES (sodium laureth sulfate) too.
