A neutralizer for permanently waving hair containing water, an oxidant and about 0.05 to about 5 weight percent of a hydrolyzed animal protein derivative having quaternary nitrogen groups bonded to the protein amino groups, and a pH value of about 2 to 11. The hydrolyzed animal protein derivative has an isoionic point of at least 9.0 and a viscosity at 10 weight percent solids in water at 25.degree. C. of about 5 to about 40 centipoises.

The second lotion used for permanent wave process by two lotions method comprising a hydrogen peroxide solution having a pH value in excess of 4.5, but not exceeding 7.5 and a hydrogen peroxide concentration of 0.3 wt % or lower, and a process for permanent waving of hair using the said hydrogen peroxide solution as the second lotion. In the process for permanent waving of hair according to the invention, treating with the second lotions preferably carried out at a temperature of 37.degree..about. 40.degree. C. Use of the permanent waving lotion of the present invention can prevent damage of the hair due to the decline of modulus of the hair after repeated permanent waving process.
Methods of permanent shaping and volumizing hair that are gentle and prevent overcurling are described. In one method using curlers to curl the hair, an alkaline permanent shaping composition having a pH of 7.6 to 11 and including a hair keratin-reducing substance is applied to the hair and allowed to act on the hair for 5 to 30 minutes at room temperature or for 2 to 20 minutes at an elevated temperature. Then the hair is optionally rinsed with water and subsequently with an acidic aqueous intermediate rinse, which has a pH of 2 to 6.5 and includes an aliphatic organic acid. Next the hair is wound onto curlers, after which the hair is allowed to rest for 30 minutes at room temperature or 20 minutes at an elevated temperature. After the resting period the hair is treated with an oxidant-based fixative, which can be a solution of hydrogen peroxide, and the curlers are removed. The hair is subsequently rinsed with water or washed with a shampoo to remove the fixative and combed into a hair style. For methods of uncurling hair the method is similar, but the step of winding on curlers is replaced by a step of combing the hair out and the acidic aqueous intermediate treating agent is in the form of a gel, cream or paste.
Keratinous material, such as human hair, in which disulfide linkages have been ruptured to form sulfhydryl groups can be permanently set using transition metal oxide compounds.
A leave-on oxidizing solution useful for permanent waving of hair containing water, an oxidant which is capable of being left on the hair and dried on the hair without damage to the hair, and an acidic agent to provide the solution with a pH value of less than about 7. The use of the leave-on oxidizing solution decreases the amount of time required for carrying out a permanent waving of hair process.
The present invention relates to a process for the production of marine invertebrate type V telopeptide containing collagen preparations from marine invertebrates, compositions containing preparations, and methods of using these preparations. The collagen preparation includes telopeptide containing and optionally invertebrate atelopeptide containing, type V fibrillar collagen. The present collagen preparations may be employed in a variety of products including for example, cosmetic, pharmacological, dental, and cell culture products.
