Why are STEARYL ALCOHOL, BENZYL ALCOHOL, and EDTA put in beauty products?

Why are these put into hair conditioner:





鈾?stearyl alcohol


鈾?benzyl alcohol


鈾?edta





why do they have to be included in the ingredients? like for example, cetyl alcohol is used in beauty products because it is used as a surfacant.
