Abstract
A hair care composition that removes calcium fatty carboxylate salts from the hair and scalp is provided. The hair care composition includes a calcium chelant, an anionic surfactant, a hydrotrope, a carrier, and optionally a zwitterionic surfactant.
Claims20
A hair care composition comprising:
- (a) from about 0.2% to about 10% of a calcium chelant by weight of the hair care composition, wherein the calcium chelant is selected from the group consisting of diethylenetriaminepentaacetic acid (DTPA), hydroxyethyl ethylenediamine triacetic acid (HEDTA), methylglycinediacetic acid (MGDA), N-(2-acetamido)iminodiacetic acid (ADA), N-(2-hydroxyethylimino)diacetic acid (HIDA), etidronic acid, pyrophosphoric acid, neridronic acid, aledronic acid, diethylenetriamine penta(methylene phosphonic acid) (DTPMP), 2-pyridinol-1-oxide (HPNO) hinokitiol, octopirox, and mixtures thereof;
- (b) from about 5% to about 40% of an anionic surfactant by weight of the hair care composition;
- (c) from about 0.1% to about 5% of a hydrotrope by weight of the hair care composition;
- and
- (d) from about 45% to about 95% of a carrier by weight of the hair care composition, wherein the pH of the hair care composition is from about 4 to about 7.

- (ii) from about 5% to about 40% of an anionic surfactant by weight of the hair care composition;
- (iii) from about 0.1% to about 5% of a hydrotrope by weight of the hair care composition;
- and
- (iv) from about 45% to about 95% of a carrier by weight of the hair care composition;
- wherein the pH of the hair care composition is from about 4 to about 7;
- and
- (b) rinsing the hair care composition from the hair.

A hair care composition comprising:
- (a) from about 0.5% to about 2% of a calcium chelant by weight of the hair care composition, wherein the calcium chelant is selected from the group consisting of diethylenetriaminepentaacetic acid (DTPA), hydroxyethyl ethylenediamine triacetic acid (HEDTA), N-(2-acetamido)iminodiacetic acid (ADA), N-(2-hydroxyethylimino)diacetic acid (HIDA), etidronic acid pyrophosphoric acid, neridronic acid, aledronic acid, 2-pyridinol-1-oxide (HPNO), hinokitiol, and mixtures thereof;
- (b) from about 5% to about 20% of an anionic surfactant by weight of the hair care composition;
- (c) from about 0.1% to about 3% of sodium xylenesulfonate by weight of the hair care composition;
- (d) from about 0.75% to about 2% of a zwitterionic surfactant by weight of the hair care composition;
- and
- (e) from about 45% to about 95% of a carrier by weight of the hair care composition, wherein the pH of the hair care composition is from about 4 to about 7.
