Hair care compositions for calcium chelation

A method for removing calcium fatty carboxylates salts from hair comprising:

• a. applying a shampoo composition to the hair comprising:
• i. from about 0.5% to about 2% of a calcium chelant by weight of the shampoo 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;
• ii. a surfactant system consisting of:
• 1. from about 5% to about 20% of an anionic surfactant by weight of the shampoo composition, wherein the anionic surfactant is selected from the group consisting of ammonium lauryl sulfate, ammonium laureth sulfate, triethylamine lauryl sulfate, triethylamine laureth sulfate, triethanolamine lauryl sulfate, triethanolamine laureth sulfate, monoethanolamine lauryl sulfate, monoethanolamine laureth sulfate, diethanolamine lauryl sulfate, diethanolamine laureth sulfate, lauric monoglyceride sodium sulfate, sodium lauryl sulfate, sodium laureth sulfate, potassium lauryl sulfate, potassium laureth sulfate, sodium lauryl sarcosinate, sodium lauroyl sarcosinate, lauryl sarcosine, cocoyl sarcosine, ammonium cocoyl sulfate, ammonium lauroyl sulfate, sodium cocoyl sulfate, sodium lauroyl sulfate, potassium cocoyl sulfate, potassium lauryl sulfate, triethanolamine lauryl sulfate, triethanolamine lauryl sulfate, monoethanolamine cocoyl sulfate, monoethanolamine lauryl sulfate, sodium cocoyl isethionate and combinations thereof;
• 2. from about 0.75% to about 2% of a zwitterionic surfactant by weight of the shampoo composition, wherein the zwitterionic surfactant is selected from the group consisting of cocamidoethyl betaine, cocamidopropylamine oxide, cocamidopropyl betaine, cocamidopropyl dimethylaminohydroxypropyl hydrolyzed collagen, cocamidopropyldimonium hydroxypropyl hydrolyzed collagen, cocamidopropyl hydroxysultaine, cocobetaineamido amphopropionate, coco-betaine, coco-hydroxysultaine, coco/oleamidopropyl betaine, coco-sultaine, lauramidopropyl betaine, lauryl betaine, lauryl hydroxysultaine, lauryl sultaine, and mixtures thereof;
• iii. from about 0.1% to about 3% of sodium xylenesulfonate by weight of the shampoo composition;
• iv. from about 45% to about 95% of a carrier by weight of the shampoo composition;
• wherein the pH of the shampoo composition is from about 4 to about 7.
• b. rinsing the shampoo composition from the hair thereby removing the calcium fatty carboxylate salts from the hair.

A method for removing calcium fatty carboxylates salts from hair comprising:

• a. applying a shampoo composition to the hair comprising:
• i. from about 0.5% to about 1.5% etidronic acid, by weight;
• ii. a surfactant system consisting of:
• 1. from about 5% to about 20% sodium laureth sulfate, by weight of the shampoo composition;
• 2.optionally from about 1% to about 12% of a zwitterionic surfactant, by weight of the shampoo composition, wherein the zwitterionic surfactant is selected from the group consisting of cocamidoethyl betaine, cocamidopropylamine oxide, cocamidopropyl betaine, cocamidopropyl dimethylaminohydroxypropyl hydrolyzed collagen, cocamidopropyldimonium hydroxypropyl hydrolyzed collagen, cocamidopropyl hydroxysultaine, cocobetaineamido amphopropionate, coco-betaine, coco-hydroxysultaine, coco/oleamidopropyl betaine, coco-sultaine, lauramidopropyl betaine, lauryl betaine, lauryl hydroxysultaine, lauryl sultaine, and mixtures thereof;
• iii. from about 0.1% to about 3% of xylene sulfonic acid by weight of the shampoo composition;
• iv. from about 45% to about 95% of water, by weight of the shampoo composition'
• wherein the pH of the shampoo composition is from about 5 to about 7;
• b. rinsing the shampoo composition from the hair thereby removing the calcium fatty carboxylate salts from the hair.
