Abstract

Active agent-containing articles, for example dryer-added articles and/or washing machine-added articles and/or hair care articles, and more particularly to consumable, single use, water-insoluble articles containing one or more active agents and optionally, one or more auxiliary ingredients, methods for making same, and methods for using same are provided.

First claim

What is claimed is:

1 . A consumable, single use, water-insoluble article comprising:
a. one or more active agents; and b. one or more auxiliary ingredients; wherein the article exhibits an Article Density of less than about 0.80 g/cm 3 as measured according to the Density Test Method; and wherein the article exhibits a Free Melt Flow of more than about 20% as measured according to the Free Melt Flow Test Method.

2 . The article according to claim 1 wherein the article comprises greater than 90% by weight of the one or more active agents.

3 . The article according to claim 1 wherein at least one of the one or more active agents comprises a fabric conditioning active agent.

4 . The article according to claim 3 wherein the fabric conditioning active agent is selected from the group consisting of: fatty acids, fatty acid derivatives, sulfonic acid derivatives, quaternary ammonium compounds, tertiary amines and salts thereof, nonionic surfactants, fatty alcohols, and mixtures thereof.

5 . The article according to claim 4 wherein the fabric conditioning active agent comprises a fatty acid selected from the group consisting of: myristic acid, stearic acid, isostearic acid, cetearic acid, dodecanoic acid, linoleic acid, oleic acid, palmitic acid, lauric acid, and mixtures thereof.

6 . The article according to claim 4 wherein the fabric conditioning active agent comprises a quaternary ammonium compound selected from the group consisting of: di(tallowyloxyethyl)hydroxyethylmethylammoniummethylsulfate, dimethyl bis(stearoyl oxyethyl)ammonium chloride, dimethyl bis(tallowyloxyethyl)ammonium chloride, dimethyl bis(tallowyloxyisopropyl)ammonium methylsulfate, and mixtures thereof.

7 . The article according to claim 4 wherein the fabric conditioning active agent comprises a fatty alcohol selected from the group consisting of: cetyl alcohol, stearyl alcohol, behenyl alcohol, lauryl alcohol, myristic alcohol, isostearyl alcohol, arachidyl alcohol, and mixtures thereof.

8 . The article according to claim 4 wherein the fabric conditioning active agent comprises a fatty alcohol and a quaternary ammonium compound.

9 . The article according to claim 8 wherein the fatty alcohol and quaternary ammonium compound are present in the article at a weight ratio of greater than 1:1.

10 . The article according to claim 4 wherein the fabric conditioning active agent comprises a fatty acid and a quaternary ammonium compound.

11 . The article according to claim 10 wherein the fatty acid and quaternary ammonium compound are present in the article at a weight ratio of greater than 1:1.

12 . The article according to claim 1 wherein at least one of the one or more active agents is selected from the group consisting of: fabric care active agents, dishwashing active agents, carpet care active agents, surface care active agents, hair care active agents, air care active agents, oral care active agents, dryer added active agents, and mixtures thereof.

13 . The article according to claim 12 wherein at least one of the one or more active agents is selected from the group consisting of: perfumes, builders, chelants, antioxidants, brighteners, sun fade inhibiting agents, UV absorbing agents, insect repellants, scents, bleaching agents, enzymes, antimicrobials, antibacterials, antifungals, perfume delivery systems, perfume microcapsules, dye transfer inhibiting agents, hueing dyes, soil release agents, colorants, preservatives, opacifiers, stabilizers, anti-shrinkage agents, anti-wrinkle agents, fabric crisping agents, reductive agents, spotting agents, germicides, fungicides, anti-corrosion agents, and mixtures thereof.

14 . The article according to claim 1 wherein at least one of the one or more auxiliary ingredients comprises a structurant.

15 . The article according to claim 1 wherein at least one of the one or more auxiliary ingredients is dispersed throughout the one or more active agents.

16 . The article according to claim 1 wherein the article transfers at least a portion of its mass to clothes in an automatic clothes dryer during use.

17 . The article according to claim 1 wherein the article comprises one or more fibrous elements.

18 . The article according to claim 1 wherein the article exhibits one or more of the following characteristics:
a. a width from about 1 cm to about 15 cm;
b. a length from about 1 cm to about 23 cm;
c. a height from about 0.01 mm to about 50 mm;
d. a mass from about 0.10 g to about 10 g;
e. a volume from about 0.25 cm 3 to about 60.00 cm 3 ; and
f. a density from about 0.05 g/cm 3 to about 0.80 g/cm 3 .

19 . The article according to claim 1 wherein the article exhibits a lamellar structure response as measured according to the Lamellar Structure Test Method.

20 . The article according to claim 1 wherein the article exhibits a lamellar structure response in a wet state but does not exhibit a lamellar structure response in a dry state as measured according to the Lamellar Structure Test Method.
