Abstract

Freshening composition having at least 70% by weight of the freshening composition of water, a perfume, wherein the perfume includes at least 60% by weight of the perfume, Perfume Raw Materials (“PRMs”) having C log P greater than 1; and at least 0.0015% by weight of the freshening composition of an alkoxylated aromatic.

First claim

wherein a, e individually is a value selected from 1-30; b, f individually is a value selected from 0-15;
wherein the value of a+b, the degree of alkoxylation, is from 3 to 30 when Q is 0, S or NR 3 and R 3 is H or C 1 -C 15 alkyl,
wherein the value of a+b, the degree of alkoxylation, is from 1 to 20 when Q is NR 3 and R 3 is (C 2 H 4 O) e (C 3 H 6 O) f R 4 ;
wherein the value of e+f, the degree of alkoxylation, is from 1 to 20 when Q is NR 3 and R 3 is (C 2 H 4 O) e (C 3 H 6 O) f R 4 ;
wherein R 1 , R 4 is independently selected from H and C 1 -C 4 alkyl;
wherein c is a value selected from 0 to 5;
wherein each R 2 is independently selected from C 1 -C 4 alkyl, C 1 -C 4 alkoxy, and wherein any two vicinal R 2 may combine to make an aliphatic or aromatic fused ring;
wherein when Q is O and R 1 is H, at least one of c or d is greater than 0.

2 . The composition of claim 1 , wherein Q is 0; preferably G is CH 2 when d is 1; when d is 1, the index c is 0, 1 or 2; when d is 0, the index c is 1 or 2; when the index c is 1, R 2 is C 1 alkyl or C 1 alkoxy, and when c is 2, two vicinal groups combine to form a fused C 6 aromatic ring.

3 . The composition of claim 1 , wherein the alkoxylated aromatic is selected from the group consisting of: an ethoxylated aromatic, an ethoxylated-propoxylated aromatic, and combinations thereof, preferably an ethoxylated aromatic.

4 . The composition of claim 3 , wherein the ethoxylate group or the propoxylate group is in any order; preferably the value of a is greater than the value of b, more preferably the value of a is greater than 2.5 times, preferably 5 times, or more preferably 9 times the value of b.

5 . The composition of claim 1 , wherein the alkoxylated aromatic is in an amount of at least 0.0015%, preferably from 0.0015% to 18%, 0.0015% to 7%, more preferably, 0.0015% to 4%, even more preferably 0.0015% to 3%, by weight of the freshening composition.

6 . The composition according to claim 1 , wherein the water is in an amount from 70% to 99.5%, preferably 90% to 99.5%, more preferably 95% to 99.5%, even more preferably 95%, by weight of the freshening composition.

7 . The composition according to claim 1 , further comprising less than 3.5%, preferably from 0.01% to 3%, more preferably from 0.01% to 1%, even more preferably from 0.01% to 0.05% of a surfactant by weight of the freshening composition; preferably the surfactant is selected from the group consisting of: nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and mixtures thereof.
