Abstract

A shampoo composition comprising an anionic phosphoric acid ester, ethylenediamine tetraacetic acid or alkali metal salt thereof and an anionic, nonionic or amphoteric surface active agent effective for shampooing hair.

Claims

1. A shampoo composition, consisting essentially of:

A. from 0.8 to 20% by weight of at least one anionic phosphoric acid ester having the formula ##STR11## wherein A is ##STR12## R is alkyl having an average carbon atom number of 10 to 18 alkenyl having an average carbon atom number of 10 to 18;

R₁ is hydrogen or methyl;

m is from 0 to 6;

n is from 1 to 6;

B is --OX₂ or --A; and

X₁ and X₂, which can be the same or different, are hydrogen, alkali metal, alkyl (C₁ -C₃)-substituted ammonium or hydroxyalkyl (C₁ -C₃)-substituted ammonium;

B. from 0.01 to 1.5% by weight of ethylenediamine tetraacetic acid or alkali metal salt thereof;

C. from 1 to 30% by weight of at least one member selected from the group consisting of water-soluble anionic organic surfactant effective for washing hair and different from said anionic phosphoric acid ester, water-soluble nonionic organic surfactant effective for washing hair and water-soluble amphoteric organic surfactant effective for washing hair; and

D. the balance is essentially water.

2. A shampoo composition as set forth in claim 1 wherein component C is at least one member selected from the group consisting of linear alkyl sulfates having an average carbon number of 10 to 14, alkylethoxy sulfates containing an alkyl group having an average carbon number of 8 to 20 and also containing 0.5 to 8 moles on the average of ethylene oxide units, fatty acid mono- and di-ethanolamides containing an alkyl group having an average carbon number of 10 to 14, alkylamine oxide amphoteric surface active agents, alkylbetaine amphoteric surface active agents and imidazoline amphoteric surface active agents.

3. A shampoo composition as set forth in claim 1 wherein component A is a monoalkyl anionic phosphoric acid ester.

4. A shampoo composition as set forth in claim 1 wherein component A is a monopolyoxyethylene-alkyl anionic phosphoric acid ester.

5. A shampoo composition as set forth in claim 1 wherein the amount of component A is 1 to 5% by weight and the amount of component B is 0.05 to 0.5% by weight.

6. A shampoo composition, consisting essentially of:

A. from 0.8 to 20% by weight of at least one anionic phosphoric ester selected from the group consisting of sodium monoalkyl and monoalkenyl phosphates having 12 to 18 carbon atoms in the alkyl and alkenyl groups, triethanolamine monoalkyl and monoalkenyl phosphates having 12 to 18 carbon atoms in the alkyl and alkenyl groups, sodium and triethanolamine salts of polyoxyethylene (p=1.0-3.0) monoalkyl and monoalkenyl phosphates having 12 to 18 carbon atoms in the alkyl and alkenyl groups, sodium and triethanolamine salts of sesquialkyl and sesquialkenyl phosphates having 12 to 14 carbon atoms in the alkyl and alkenyl groups, and sodium and triethanolamine salts of polyoxyethylene (p=1.0-3.0) sesquialkyl and sesquialkenyl phosphates having 12 to 14 carbon atoms in the alkyl and alkenyl groups;

B. from 0.01 to 1.5% by weight of ethylenediamine tetraacetic acid or alkali metal salt thereof;

C. from 1 to 30% by weight of at least one member selected from the group consisting of water-soluble anionic organic surfactant effective for washing hair and different from said anionic phosphoric acid ester, water-soluble nonionic organic surfactant effective for washing hair and water-soluble amphoteric organic surfactant effective for washing hair; and

D. the balance is essentially water.

7. A shampoo composition as set forth in claim 6 in which component B is disodium ethylenediamine tetraacetate.
