It's a mixture of synthetic surfactants and thickeners and so forth. Soap itself is a surfactant: basically a mixture of 'ates' eg sodium palmate, sodium cocoate, sodium olivate, sodium stearate. Most shampoo you find in stores relies on one common synthetic surfactant, sodium lauryl sulfate. Now, I'm old enough to be able to remember using actual shaving soap - came in a tin - and compared with modern shaving gels, well, I don't care for the idea. And I am a bit fed up paying through the nose for these gels. So I just got mine from the bathroom:
Water, Palmitic acid, TEA, Stearic acid, Sunflower oil glyceride, Sorbitol, Aloe vera, fragrance
Now, I love aloe vera and I have to have it, and a soap won't have that, at least not in the 25% I'll put in my mix. Above, it is only about 2% Here's the formula with probable % and possible alternatives:
Water . . . . Q/S to 100% Palmitic acid . . . . . . . . . palm oil, I believe; maybe 7% TEA . . . . . . . . . . . . . . . not quite sure what this is here for, just to adjust final pH to 5.9 probably. You could use NaOH instead. Stearic acid . . . . . . . . . . basic building block easily obtained, perhaps 5% Sunflower oil glyceride . . fractionated sunlower oil, I think I would substitute capric/caprylic triglyceride at say 2% Sorbitol . . . . . . . . . . thickener and hydrating agent, usage say, 2% Aloe vera . . . . . . . . . . . their usage, cheapskates, about 2% tops, mine would be 25% fragrance . . . . . . . . . . . 1% typically, Drax Black from IFF!
In addition I would include Glucamate LT as a thickener and sensorial, and I really am wondering how the h--- that formula works anyway. Where is the emulsifier? I think it is incomplete. Add 5% glycerine monostearate.
