I make one tweaked, so no SLS in mine. I tweaked Susan's one. It is very gentle
ere's what I consider to be the basic recipe for making a shampoo bar...
50 to 65% powdered surfactants I use DLS mild
10 to 26% liquid surfactants mine cocobeataine and bioterge AS-40
2 to 7% bar hardener like stearic acid, cetyl alcohol, or sodium lactate (liquid)Cetyl alcohol
1 to 3% emulsifiers (usually e-wax, but BTMS would double duty here)Bmts-50
2 to 7% conditioning agent like Incroquat CR or BTMS also Bmts-50
2 to 3% butters - shea, mango, cocoa Cocoa or mango I do not like shea butter
1 to 2% hydrolyzed proteins 2% of Oat protein next time I will try silk
1 to 4% silicones - dimethicone at 1 to 2%, cyclomethicone at 1 to 2%
.5 to 2% panthenol
1 to 2% fragrance or essential oils
0.5% to 1% preservative
No scalp itching, hair nice soft and shiny
