20% coco betaine can use another or two together, coco glucoside or decylglucoside and coco betaine, although you may need to adjust the ph.
5% slsa or sodium coco sulfate
4% glycerin or castor, light oils don’t work well
4% cocomide DEA
1% preservative of choice (use preservative guidelines)
1% fragrance oil (If you choose you can add poly 80) if you do subtract that amount from water amount.
Add the 4% glycerin or castor oil to the SLSA and make a paste. Add 1-2 oz water and Stick blend to remove lumps. Add coco betaine and coco DEA to each other and add to slsa or SCS mixture after lumps are out of SLSA or SCS/water mixture, then add that mixture to remaining water. Stir gently by hand to keep bubbles from forming.
