wherein the one or more fatty compounds are present in a total amount ranging from 0.5% to 20% by total weight of the composition; the one or more fatty alcohol(s) are present in a total amount ranging from 0.5% to 20% by total weight of the composition; the one or more non-ionic surfactant(s) other than fatty alcohols are present in a total amount ranging from 0.2% to 5% by total weight of the composition; and
wherein the composition is free of a cationic surfactant and an anionic surfactant.
2. The composition according to claim 1 , wherein the ratio between the total amount of fatty alcohols and the total amount of non-ionic surfactants other than fatty alcohols comprised in the second aqueous component ranges from 10:0.5 to 10:3.
