DE1492169B - Preparations for setting hair, containing protein hydrolysis products - Google Patents

Description

Substances that are applied to the hair in a sprayable form or as a solution and after vaporization The solvent leaves a firming film on the hair, a number of must of requirements that are made by practice. The setting film should adhere well to the hair and resistant to mechanical stress - e.g. B. Combing or brushing · - the hair being. If the film comes off in the form of dust or even flakes, it cannot be used. That sets a certain flexibility of the film, which on the other hand ensure sufficient firmness got to. In high humidity, the film must not become sticky, but should be treated with commercially available Let the shampoo wash out without difficulty. Other desirable properties of the film are sufficient Transparency and a glossy effect.

Both natural and synthetic setting substances only meet these requirements partly. So far, shellac, zein, gelatin, karaja gum and alginates have been used for this purpose. These natural products should not be brought into solution in the concentrations that are sufficient Ensure consolidation and, on the other hand, absorb so much moisture due to their water solubility from the air that the film becomes sticky and no longer flexible enough to set the hairstyle.

Surprisingly, it has now been found that a excellent hairstyle stabilization while improving shine and elasticity can be determined when the hair is treated with a spray or a solution of protein hydrolysis products Molecular weight is treated. The production of these protein hydrolysis products is for example in German patents 1000 388, 695 940 and 694 294.

An important prerequisite for good setting properties is the correct molecular size of the Peptides. Substances with a formula number from 5 to 18 are preferably suitable. You get this Substances in the form of mixtures, in that the degradation process is interrupted as soon as the reaction solution is reached has a form number of this range.

These peptides were previously used as skin-friendly additives to shampoos, cold waves and foam baths used. Their physiological harmlessness is therefore assured .. Due to their structural similarity with the keratin of human hair, the effects according to the invention Fixes a healthy and natural look to the hair.

The elasticity and hardness of the setting film can be determined by combining the protein hydrolysis products with Plasticizers such as polyglycols of various molecular weights, ethylene glycols, diethylene glycols and glucose can vary as desired within wide limits. Customary additives such as perfume, dye etc. be included. The solvents used are water or lower aliphatic alcohols such as Ethyl and isopropyl alcohol with a proportion of about 50% water is used. The remedy can be in different Procedures are applied. When using the hair set in spray form have the commercially available halogenated hydrocarbons such as trichloromonofluoromethane etc. as Propellant proved suitable. Depending on the desired spray properties, the various Propellants are combined. This setting hairspray is applied to dry hair - most of the time on the finished hairstyle - applied.

Another method is an aqueous or aqueous alcoholic solution of the protein hydrolyzate distributed in damp hair before it is placed in the desired hairstyle shape to dry or is rolled up.

The agent according to the invention is explained below with reference to the examples, but which extend the scope of the Not intended to limit the invention. Rather, the scope of the invention is indicated by the above Claims determined and limited.
