Abstract
Abstract Stable, aqueous or aqueous-alcoholic solutions of fat-soluble perfume oils, containing hydroxyalkyl ether-ethoxylates of the formula ##STR1## wherein R 1 and/or R 2 are an alkyl group having 1 to 24 carbon atoms or hydrogen, and R 3 and/or R 4 are an alkyl group having 2 to 22 carbon atoms or hydrogen, and x and y independently are integers of from 1 to 16, with the proviso that the total of the carbon atoms of R 1 +R 2 or R 3 +R 4 is from 2 to 26 and the total of the integers x+y is a value of from 2 to 18.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
242 words
Clear, stable, aqueous or aqueous-alcoholic solutions of a fat-soluble ethereal perfume oil, consisting essentially of (1) from 0.5 to 5% by weight, relative to the total weight of the solution, of a hydroxyalkyl ether-ethoxylate intermediary of the formula ##STR7## wherein R 1 and R 2 independently of each other are a member selected from the group consisting of alkyl having 1 to 24 carbon atoms, or R 3 and R 4 independently of each other are a member selected from the group consisting of alkyl having 2 to 22 carbon atoms and hydrogen, and x and y independently of each other are an integer from 1 to 16, with the proviso that the total of the carbon atoms of R 1 +R 2 or R 3 +R 4 is from 2 to 26, and with the further proviso that the total of the integers x+y is from 2 to 18, (2) from 0.1 to 1% by weight relative to the total weight of the solution of a fat-soluble etheral perfume oil, wherein the amount of said ester-ethoxylate intermediary is at least four times the amount of said perfume oil, (3) from 0 to 10% by weight of a water-miscible alcohol, and (4) the remainder to 100% by weight of the conventional substances used in said solutions 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.
Claim 2
Dependent Claim
242 words
Clear, stable, aqueous or aqueous-alcoholic solutions of a fat-soluble ethereal perfume oil, consisting essentially of (1) from 0.5 to 5% by weight, relative to the total weight of the solution, of a hydroxyalkyl ether-ethoxylate intermediary of the formula ##STR7## wherein R 1 and R 2 independently of each other are a member selected from the group consisting of alkyl having 1 to 24 carbon atoms, or R 3 and R 4 independently of each other are a member selected from the group consisting of alkyl having 2 to 22 carbon atoms and hydrogen, and x and y independently of each other are an integer from 1 to 16, with the proviso that the total of the carbon atoms of R 1 +R 2 or R 3 +R 4 is from 2 to 26, and with the further proviso that the total of the integers x+y is from 2 to 18, (2) from 0.1 to 1% by weight relative to the total weight of the solution of a fat-soluble etheral perfume oil, wherein the amount of said ester-ethoxylate intermediary is at least four times the amount of said perfume oil, (3) from 0 to 10% by weight of a water-miscible alcohol, and (4) the remainder to 100% by weight of the conventional substances used in said solutions 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.
Claim 3
Dependent Claim
