I'm making a shampoo. I know the the surfactants are not supposed to be more than 30 percent of the formula. My question is if I want to use coca betaine as a surfactant and a foam booster how would if it makes my surfactants over 30 percent?
My surfactants are
Lauryl glucoside 10%
Coca Betaine 15%
Sci powder 5% ( sodium cocoyl isethionate)
Decyl glucoside 8%
