Abstract

A solid dissolvable composition comprising a crystallizing agent, water, and a freshness benefit agent.

Claims (32)

1 . A solid dissolvable composition comprising:

crystallizing agent;

water;

and freshness benefit agent;

wherein the crystallizing agent is the sodium salt of saturated fatty acids having from 8 to about 12 methylene groups;

wherein the freshness benefit agent is at least one of a neat perfume, pro-perfume, or a malodor counteractant; and

wherein the sodium salt of saturated fatty acids of the crystallizing agent comprises from 50 wt. % to 70 wt. % C12, 15 wt. % to 25 wt. % C10, and 15 wt. % to 25 wt. % C8.

2 . The solid dissolvable composition of claim 1 , wherein the sodium salt of saturated fatty acids comprises between 30% and 80% percent slow crystallizing agent (% slow CA).

3 . The solid dissolvable composition of claim 1 , wherein the crystalizing agent is in the form of a fiber as determined by the FIBER TEST METHOD.

4 . The solid dissolvable composition of claim 1 , wherein the amount of water is less than 50 wt. % of the final solid dissolvable composition as determined by the MOISTURE TEST METHOD.

5 . The solid dissolvable composition of claim 1 , wherein the solid dissolvable composition has a dissolution rate of solubility percent greater than 5% at 37° C., as determined by the DISSOLUTION TEST METHOD.

6 . The solid dissolvable composition of claim 1 , where the pro-perfume comprises at least one of Michael adducts, amines, alkylidenes, silicones, aromatic imines, non-aromatic imines, oxazolidines, beta-keto esters, or orthoesters.

7 . The solid dissolvable composition of claim 1 , where the pro-perfume comprises at least one of beta-oxy carbonyl or beta-thio carbonyl.

8 . The solid dissolvable composition of claim 7 , where the pro-perfume comprises at least one of alpha-unsaturated ketone, beta-unsaturated ketone, aldehyde or carboxylic ester.

9 . The solid dissolvable composition of claim 1 , where the pro-perfume comprises at least one of silicic acid esters, polysilicic acid esters, or silicone polymers.

10 . The solid dissolvable composition of claim 1 , where the pro-perfume comprises aminosilicone.

11 . The solid dissolvable composition of claim 1 , where the pro-perfume comprises a polymeric amine.

12 . The solid dissolvable composition of claim 8 , where the pro-perfume comprises at least one of polyalkylimine or aminosilicone.

13 . The solid dissolvable composition of claim 12 , where the pro-perfume comprises at least one of polyethyleneimine (PEI) or polyvinylamine (PVAm).

14 . The solid dissolvable composition of claim 1 , where the pro-perfume comprises monomeric amine.

15 . The solid dissolvable composition of claim 14 , where the pro-perfume comprises at least one of hydroxyl amines or aromatic amines.

16 . The solid dissolvable composition of claim 7 , where the pro-perfume comprises an alkylidene-containing compound according to formula (I):

wherein: A is a hydrocarbon residue of an aldehyde-containing perfume raw material (e.g., A-CHO), wherein the hydrocarbon residue may optionally contain one or more heteroatom(s) selected from the group consisting of oxygen, nitrogen, sulfur, silicon, and mixtures thereof; and

X and Y are independently selected from the group consisting of a nitrile group (—CN), a keto group (—C(O)R), and an ester group (—C(O)OR′), wherein R and R′ are independently alkyl groups having from one to ten carbon atoms, preferably alkyl groups independently selected from methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, iso-butyl, and pentyl groups.

17 . The solid dissolvable composition of claim 6 , where the pro-perfume comprises an alkylidene-containing compound according to formula (II):

wherein: A is a hydrocarbon residue of an aldehyde-containing perfume raw material (e.g., A-CHO), wherein the hydrocarbon residue may optionally contain one or more heteroatom(s) selected from the group consisting of oxygen, nitrogen, sulfur, silicon, and mixtures thereof.

18 . The solid dissolvable composition of claim 1 wherein the sodium salt is at least one of sodium C8, sodium C10, or sodium C12.

19 . A method of producing a solid dissolvable composition comprising:

a) providing at least one of a neat perfume, pro-perfume, or a malodor counteractant;

b) mixing a solid dissolvable composition mixture, by solubilizing a crystallizing agent in water;

c) forming, by converting and maintaining the solid dissolvable composition mixture into the desire shape and size by at least one of crystallization, partial drying, salt addition or viscosity build from liquid crystal formation; and

d) drying, by removing water to produce a solid dissolvable composition.
