Claim 1

Clear, stable, aqueous or aqueous-alcoholic solutions of a fat-soluble ethereal perfume oil or vitamin, consisting essentially of from 0.5% to 5% by weight, relative to the total weight of the solution, of a hydroxyalkyl ester-ethoxylate intermediary of the formula ##STR18## wherein R 1 and R 2 independently of each other are a member selected from the group consisting of alkyl having 1 to 18 carbon atoms and hydrogen, R 3 is a member selected from the group consisting of alkyl having 1 to 5 carbon atoms and phenyl, and n is an integer from 6 to 40 with the proviso that the total of the carbon atoms of R 1 +R 2 is from 6 to 20, from 0.1% to 1% by weight relative to the total weight of the solution of a fat-soluble ethereal perfume oil or fat-soluble vitamin, wherein the amount of said ester-ethoxylate intermediary is at least four times the amount of said perfume oil or vitamin, from 0 to 10% by weight of a water-miscible alcohol, and the remainder to 100% by weight of the conventional substances used in said solution including water where the amount of water or water and alcohol is from 70% to 99% by weight, relative to the total weight of the solution.
