Abstract

A fabric freshening product that includes (a) freshening aqueous liquid composition including a bispyridinium alkane antimicrobial active and a perfume, and (b) a spray device to produce a spray of the composition.

First claim

What is claimed is:

1. A method of freshening and sanitizing a fabric comprising the step of using a fabric freshening product,
wherein the fabric freshening product comprises:
(a) a freshening aqueous liquid composition comprising from about 0.001% to about 1% by weight of the composition of octenidine dihydrochloride,
wherein the composition is an aqueous composition comprising from about 90% to about 99.5% by weight of the composition of water,
the composition further comprising a perfume, and
wherein the composition is a Newtonian fluid; and

(b) a spray device to produce a spray of said composition;

wherein the step of using the product comprises spraying a fabric with the composition.

2. The method according to claim 1 , wherein the octenidine dihydrochloride is the only antimicrobial active present in the composition.

3. The method according to claim 1 , wherein the composition comprises from about 0.0025% to about 0.5% by weight of the composition of the octenidine dihydrochloride.

4. The method according to claim 1 , wherein the composition comprises at least 0.001% by weight of the composition of perfume.

5. The method according to claim 1 , wherein the perfume comprises at least about 60% by weight of the perfume of perfume raw materials having Clog P greater than 1.0.

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

7. The method according to claim 1 , wherein the composition further comprises from about 0.01% to about 5% of a solvent by weight of the composition, wherein the solvent is selected from the group consisting of: an alcohol, a polyol and mixtures thereof.

8. The method according to claim 1 , wherein the composition further comprises an alkoxylated phenol according to Formula (I):

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

9. The method according to claim 1 , wherein the composition further comprises a wetting agent selected from the group consisting of: block co-polymers of ethylene oxide and propylene oxide, block copolymers of silicone, and mixtures thereof.

10. The method according to claim 1 , wherein the composition further comprises a setting polymer.

11. The method according to claim 1 , wherein the composition further comprises an anti-wrinkle agent.

12. The method according to claim 1 , wherein the composition further comprises a malodor counteractant, wherein the malodor counteractant is selected from the group consisting of: polyols, cyclodextrin and derivatives thereof, amine functional polymers, aldehydes, and combinations thereof.

13. The method according to claim 1 , further comprising PRMs having ClogP greater than 1 and selected from the group consisting of: dihydro myrcenol, isonoylalcohol, citronellol, tetrahydro linalool, tepinyl acetate, geranyl acetate, phenyl ethyl phenyl acetate, lilial (P. T. Bucinal), vertenex, diphenyl methane, p′cymene, alpha pinene, benzyl salicylate, d-limonene, cis-hexenyl salicylate, hexyl cinnamic aldehyde, cedryl acetate, habanolide, ethyl trimethylcyclopentene butanol, hexyl salicylate, iso e super, ethyl vanillin, helional, undecalactone, ionone gamma methyl, hydroxycitronellal, cyclo galbanate, pyranol, verdox, linalyl acetate, benzyl acetate, methyl phenyl carbinyl acetate, triplal, and mixtures thereof.

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

15. The method according to claim 1 , wherein the composition further comprises C4-C16 thio-damascone.

16. The method according to claim 1 , wherein the spray device is made of plastic, wherein the plastic is selected from the group consisting of: polypropylene, polyethylene terephthalate, high density polyethylene, and combinations thereof.
