Abstract

A personal care composition includes a structured cleansing phase; a benefit phase including triglycerides, a cationic deposition polymer, and anionic microcapsules; and a carrier; and methods relating thereto.

First claim

What is claimed is:

1 . A personal care composition comprising:
a structured cleansing phase comprising about 2% to about 50% of an anionic surfactant; a benefit phase comprising triglycerides; from about 0.01% to about 2% of a first cationic deposition polymer; a plurality of anionic microcapsules; and a carrier.

2 . The personal care composition of claim 1 , wherein said triglycerides comprise at least one triglyceride oil.

3 . The personal care composition of claim 2 , wherein said triglyceride oil is selected from the group consisting of olive oil, sunflower oil, soybean oil, peanut oil, rapeseed oil, almond oil, palm oil, coconut oil, palm kernel oil, and mixtures thereof.

4 . The personal care composition of claim 1 , wherein said cationic deposition polymer and said plurality of anionic microcapsules are added to the personal cleansing composition as a premix.

5 . The personal care composition of claim 1 , wherein the structured cleansing phase and the benefit phase are in physical contact with each other.

6 . The personal care composition of claim 1 , wherein the anionic surfactant is selected from the group consisting of ammonium lauryl sulfate, ammonium laureth sulfate, sodium lauryl sulfate, sodium laureth sulfate, potassium laureth sulfate, sodium lauryl sarcosinate, sodium lauroyl sarcosinate, lauryl sarcosine, cocoyl sarcosine, ammonium cocoyl sulfate, potassium lauryl sulfate, and combinations thereof.

7 . The personal care composition of claim 1 , wherein the structured aqueous phase further comprises a second cationic deposition polymer.

8 . The personal care composition of claim 7 , wherein the cationic deposition polymer is selected from the group consisting of starches, guar, cellulose, Cassia, locust bean, Konjac, Tara, galactomannan, and tapioca.

9 . The personal care composition of claim 1 , wherein the anionic surfactant comprises sodium laureth(n) sulfate.

10 . The personal care composition of claim 1 , wherein the microcapsules comprise a core material and a wall material, the wall material selected from the group consisting of those formed from melamine-formaldehyde or urea-formaldehyde condensates, melamine-resorcinol or urea-resorcinol condensates, aminoplasts, gelatin, polyurethane, polyamide, polyolefin, polysaccharide, protein, silicone, lipid, modified cellulose, gums, polyacrylate, polyphosphate, polystyrene, and polyesters, or combinations thereof.

11 . A personal care composition comprising:
a structured cleansing phase comprising 2% to 30%, by weight of the composition, of an anionic surfactant; a benefit phase comprising triglycerides; from 0.05% to 5%, by weight of the composition, of a microcapsule premix comprising a first cationic deposition polymer and anionic microcapsules; and a carrier.

12 . The personal care composition of claim 11 , wherein the first cationic deposition polymer has a molecular weight of 300,000 Da to 2,000,000 Da.

13 . The personal care composition of claim 12 , wherein the first cationic deposition polymer comprises polyvinyl formamide.

14 . The personal care composition of claim 13 , wherein the anionic microcapsules comprise a shell comprising polyacrylate, melamine formaldehyde, or a combination thereof.

15 . The personal care composition of claim 14 , wherein the anionic microcapsules comprise a core comprising perfume.

16 . The personal care composition of claim 11 , wherein the blending ratio of the structured cleansing phase to the benefit phase is 50:50.

17 . A method of making a personal cleansing composition, the method comprising:
adding a microcapsule premix, said premix comprising a plurality of anionic microcapsules and a cationic deposition polymer to a mixture comprising a structured cleansing phase comprising about 2% to about 30% of an anionic surfactant; a benefit phase comprising triglycerides; and a carrier; to form a personal cleansing composition.

18 . The method of claim 17 , wherein said triglycerides comprise at least one triglyceride oil.

19 . The method of claim 18 , wherein said triglyceride oil is selected from the group consisting of olive oil, sunflower oil, soybean oil, peanut oil, rapeseed oil, almond oil, palm oil, coconut oil, palm kernel oil, and mixtures thereof.

20 . The method of claim 19 , wherein the cationic deposition polymer comprises polyvinyl formamide.
