  • Shower gel clumps and water separates

    Posted by Faa on May 20, 2023 at 6:51 am

    Hi, i am new to formulation and i have prepared a liquid shower gel but i ended up with a product which settles down in the bottom and water floats up. please help me figuring out where i did wrong.

    68.5% Distilled water

    20% Cocamidopropyl betaine

    9% Glycerin

    1% Guar gum

    0.5% Liquid germall plus

    1% Lavendar Essential oil

    a pinch of Mica powder

    First i dissolve guar gum into glycerin and add germall plus, essential oil, mica and distilled water. then i incorporated everything into cocamidopropyl betaine.

    i was fine at that moment but after leaving it for whole night, water separates out leaving thick solution at the bottom.

    First, I’d completelt remove Glycerin (not doing much in rinse-off products, but impair your foam). Then, change your guar gum for a more compatible thickener with surfactant based systems. For hard to thicken systems, I’d try with Crothix Liquid, but there are few more. Also, if you don’t want to use SLES, you could still use another anionic surfactants (the foam of CAPB alone isn’t pleasant). Also, EO are always a concern when it comes to allergenicity, so keep them at very low levels (if at all). And be sure you’re using a broad spectrum preservative system.
