Abstract

Freshening composition having at least 85% by weight of the freshening composition of water; at least 0.0015% of by weight of the freshening composition of alkoxylated phenol; and a perfume having at least 60% by weight of the perfume, Perfume Raw Materials having ClogP greater than 1.0. The alkoxylated phenol is according to Formula (I):

wherein a is a value selected from 3 to 15; b is a value selected from 0 to 12;
wherein the value of a+b, the degree of alkoxylation is from 3 to 15.

First claim

What is claimed is:

1. A freshening composition comprising:
at least 85% by weight of the freshening composition of water;
a perfume, wherein the perfume comprises perfume raw materials in an amount of at least 60% by weight of the perfume, the perfume raw materials having a ClogP greater than 1.0;
from about 0.1% to about 2% by weight of the freshening composition of polyethyleneimine; and
at least 0.0015% by weight of the freshening composition of an alkoxylated phenol; wherein the alkoxylated phenol is according to Formula (I):

wherein a is a value selected from 3 to 15; b is a value selected from 0 to 12;
wherein the value of a +b, degree of alkoxylation is from 3 to 15.

2. The composition of claim 1 , wherein the alkoxylated phenol is selected from the group consisting of: ethoxylated phenol, ethoxylated-propoxylated phenol, and combinations thereof.

3. The composition of claim 2 , wherein the ethoxylated phenol is according to Formula (II):

wherein an average value of c, degree of ethoxylation is 3≤c≤15.

4. The composition of claim 1 , wherein the alkoxylated phenol is in an amount of from 0.0015% to 9% by weight of the freshening composition.

5. The composition of claim 1 , wherein the water is in an amount from 85% to 99.5% by weight of the freshening composition.

6. The composition according to claim 1 , further comprising less than 3.5% of a surfactant by weight of the freshening composition, wherein the surfactant is selected from the group consisting of: nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and mixtures thereof.

7. The composition according to claim 1 , further comprising less than 10% of a solvent by weight of the freshening composition, wherein the solvent is selected from a group consisting of: an alcohol, a polyol and mixtures thereof.

8. The composition according to claim 7 , wherein the solvent is ethanol, wherein the ethanol is in an amount of less than 10%, and wherein the ethanol and the alkoxylated phenol define a solvent system.

9. The composition according to claim 7 , wherein the composition is substantially free of the solvent.

10. The composition of claim 1 , wherein the perfume is in an amount of at least 0.001% by weight of the freshening composition.

11. The composition according to claim 1 , wherein the perfume raw materials having ClogP greater than 1 are selected from the group consisting of: dihydro myrcenol, isonoyl alcohol, citronellol, tetrahydro linalool, tepinyl acetate, geranyl acetate, phenyl ethyl phenyl acetate, lilial P.T. Bucinal, 4-tert-butylcyclohexyl acetate, diphenyl methane, p-cymene, alpha pinene, benzyl salicylate, d-limonene, cis-hexenyl salicylate, hexyl cinnamic aldehyde, cedryl acetate, ethyl trimethylcyclopentene butanol, hexyl salicylate, ethyl vanillin, undecalactone, ionone gamma methyl, hydroxycitronellal, cyclo galbanate, 2-tert-butylcyclohexyl acetate, linalyl acetate, benzyl acetate, methyl phenyl carbinyl acetate, and mixtures thereof.

12. The composition according to claim 3 , wherein an average value of c, the degree of ethoxylation is from 5 to 7, and wherein at least 80% by weight of the perfume of perfume raw materials have a ClogP greater than 2.0.

13. The composition according to claim 3 , wherein the total weight ratio of the ethoxylated phenol to the perfume is 0.01:1 to 9,000:1.

14. The composition according to claim 1 , wherein the freshening composition comprises a sulfur-containing pro-perfume.

15. The composition according to claim 14 , wherein the sulfur-containing pro-perfume is a C4-C16 thio-damascone.

16. A non-aerosol freshening sprayer product comprising:
a plastic container containing a freshening composition according to claim 1 , wherein the plastic container comprises a material selected from the group consisting of: polypropylene, polyethylene terephthalate, high density polyethylene and combinations thereof.

17. A method of freshening comprising the step of spraying a freshening composition according to claim 1 onto a surface or into air.
