Home Cosmetic Science Talk Formulating My Shower Gel Formula

  • My Shower Gel Formula

    Posted by Av3553 on January 10, 2023 at 8:31 pm

    I have come up with this formula for my shower gel however, I feel like I’m using too much SLeS and Cocamidopropyl betaine. I’m wondering if I lower the percentages of SLeS and CAPB, decrease glycerin and increase the water content, will I still be able to achieve a gel form? Also, once I’ve put the formula together, I end up having to add about another 10-15% EXTRA cocamidopropyl betaine to achieve the viscosity I want. At that point, that’s when I adjust the pH. Should I adjust pH before adding certain things to the formula since I know pH can affect viscosity. What pH do y’all prefer on shower gels? Do y’all think I should remove any of the ingredients from the formula or add something to help achieve gel? Here’s what I’m working with so any input would help out. 

    Ingredients Percentage
    Water   30
    SLeS     30
    Cocomydopropyl Betaine   18
    Glycerine   12
    Sodium Cocoamphoacetate   8
    Fragrance   1
    Preservative    1

    @Av3553 For a rinse-off product, you’re better off without glycerin. Remove it, and you’ll be able to reduce SLES and Betaine, and still get that gel phase.

    Perfect, thanks @ketchito! I’ve seen previous comments you’ve left on other people about leaving out the glycerin. So I’ll definitely try that out. One question, I’m definitely going to be increasing water percentage, right?

    @Av3553 Yes indeed, you’ll need to increase water percentage by the same level of the glycerine you replace.
