Hi. I am new to formulating and looking to copy a hair conditioner that has the ingredients below but I have some questions: 1) Can these ingredients be considered safe to use as a leave-in conditioner? Labels say "rinse out" but I'm not sure why. 2) The product is too thin, what could I add to thicken it? 3) Since water is the first ingredient can this be considered a "water-based" conditioner?
Ingredients: Water, Cetearyl Alcohol, Isopropyl Palmitate, Brassicamidopropyl Dimethylamine, L-Aspartic acid, Tetrasodium EDTA, Methylisothiazolinone, Methylchloroisothiazolinone.
