Abstract
A process for permanently deforming keratin fibers is provided wherein the fiber is treated with 1) a keratin-reducing substance, 2) a physiologically compatible salt of an organic or inorganic acid anion and a divalent cation or Al.sup.3+, and 3) a compound selected from the group consisting of Vitamin C, Vitamin B.sub.5, derivatives thereof and mixtures thereof. The salt 2) and compound 3) can be applied in the form of a wave lotion or an intermediate treatment formulation. Also provided are wave lotions and hair treatment formulations comprising the salt 2) and the compound 3).
Claims18
A process for permanently deforming keratin fibers, comprising:
- a. mechanically deforming a keratin fiber;
- b. treating the fiber with 1) a keratin-reducing substance, 2) a physiologically compatible salt of an organic or inorganic acid anion and a divalent cation or Al.sup.3+, and 3) a compound selected from the group consisting of vitamin C, vitamin B.sub.5, derivatives thereof, and mixtures thereof;
- c. fixing said treated and deformed fiber with an aqueous oxidizing agent;
- and
- d. rinsing the oxidizing agent from the fiber.
A wave lotion comprising:
- a. a keratin-reducing mercaptan;
- b. a physiologically compatible salt of an organic or inorganic acid anion and a divalent cation or Al.sup.3+ ;
- and
- c. a compound selected from the group consisting of Vitamin C, Vitamin B.sub.5, derivatives thereof, and mixtures thereof.
A wave lotion having a pH of 5 to 10 comprising:
- a. 0.5 to 1.0 moles/kg of a keratin-reducing mercaptan;
- b. 0.1% to 10% by weight of a physiologically compatible salt of an organic or inorganic acid anion and a divalent cation or Al.sup.3+ ;
- and
- c. 0.1% to 10% by weight of a compound selected from the group consisting of Vitamin C, Vitamin B.sub.5, derivatives thereof, and mixtures thereof.
A hair treatment formulation comprising:
- a. 0.1% to 10% by weight of a physiologically compatible salt of an organic or inorganic acid anion and a divalent cation or Al.sup.3+ ;
