Abstract

A personal care composition comprising a surfactant system consisting essentially of an anionic surfactant and a zwitterionic surfactant; a preservative; a pH modifier; and a rheology modifier, wherein the ratio of anionic surfactant to zwitterionic surfactant is about 1:1 to about 2.2:1 of the total composition by weight.

First claim

What is claimed is:

1. A personal care composition comprising:
a surfactant system consisting essentially of an anionic surfactant sodium laureth sulfate and a zwitterionic surfactant cocoamidopropyl betaine;
a preservative the comprises sodium benzoate;
a pH modifier that comprises lactic acid; and
a rheology modifier that comprises sodium chloride,
wherein the rheology modifier is present in a total amount of 0.01 wt % to 10 wt % of the personal care composition, and
wherein the weight ratio of sodium laureth sulfate to cocamidopropyl betaine is from about 1:6 to about 1:8.

2. The personal care composition of claim 1 , wherein the composition is free of other anionic surfactants.

3. The personal care composition of claim 1 , wherein the composition is free of other zwitterionic surfactants.

4. The personal care composition of claim 1 , wherein the composition is free of other surfactants.

5. The personal care composition of claim 1 , wherein the pH modifier further comprises a compound selected from citric acid, hydrochloric acid, glycolic acid, sodium hydroxide, potassium chloride, monosodium citrate, disodium citrate, monosodium malate, sodium carbonate, bicarbonates, sesquicarbonates, borates, silicates, monosodium phosphate, trisodium phosphate, pyrophosphate salts, imidazole, and a combination of two or more thereof.

6. The personal care composition of claim 1 , wherein the preservative further comprises a compound selected from sodium salicylate; benzalkonium chloride; benzethonium chloride; 5-bromo-5-nitro-1,3-dioxane; 2-bromo-2-nitropropane-1,3-diol; alkyl trimethyl ammonium bromide; N-(hydroxymethyl)-N-(1,3-dihydroxy methyl-2,5-dioxo-4-imidaxolidinyl-N-(hydroxy methyl)urea; 1-3-dimethyol-5,5-dimethyl hydantoin; formaldehyde; iodopropynyl butyl carbamate, butyl paraben; ethyl paraben; methyl paraben; propyl paraben, methyl isothiazolinone, methyl-chloroisothiazoline; phenoxyethanol; tris-hydroxyethyl-hexahydrotriazine; methylisothiazolinone; 5-chloro-2-methyl-4-isothiazolin-3-one; 1,2-dibromo-2,4-dicyanobutane; 1-(3-chloroalkyl)-3,5,7-triaza-azoniaadamantane chloride; organic acids; or combinations thereof.

7. The personal care composition of claim 1 , wherein the surfactant system comprises about 5 wt % to about 15 wt % of the personal care composition.

8. The personal care composition of claim 1 , wherein the composition is in a form selected from a liquid hand soap, a shower gel, a body wash, a shampoo, a liquid face soap, a dish soap, a body wash, a dermal cream, and a liquid detergent.

9. The personal care composition of claim 1 , further comprising one or more optional ingredients selected from a fragrance; a skin conditioning agent; a moisturizing agent; a dye; a pigment; a chelating agent; a sunscreen active ingredient; an antiaging compound; an antioxidant; a vitamin; an essential oil; and a combination of two or more thereof.

10. A method of cleansing skin comprising applying to the skin a composition according to claim 1 .
