Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to agents for reduction or oxidation steps in the permanent processing of hair.

In conventional permanent hair treatments, hair is first treated with an aqueous solution of reducing compounds, especially mercapto compounds, especially thioglycolates in alkaline systems or sulfites in weakly acidic or neutral systems. be done. This breaks the disulfide crosslinks in hair keratin through a chemical reaction, allowing the hair to be easily permanentized.

There are generally two methods used to permanently process human hair. In the first method, the hair is first washed and dried with a towel, then divided into several strands, each of which is moistened with a portion of the permanent solution and wound into curlers. After winding, moisten the hair with the remaining permanent treatment solution. In the second method, the hair is first similarly washed, dried with a towel, and then divided into several bundles, but then wound into curlers without being pre-moistened with a permanent solution. . After the winding is completed, the entire required amount of permanent finishing agent liquid is applied to the hair. By the way, in these cases, a curler with a diameter of about 5 to 13 mm is used for permanent waving, and a curler with a diameter of about 13 mm is used for wave removal.
Curlers with a diameter of a millimeter or more are used.

The action of the permanent processing agent on the hair is selected depending on the properties of the hair and the desired degree of processing, but it is generally about 30 minutes for both permanent wave processing and wave removal processing. . By heating, for example by using a heat radiator or a food dryer, the working time can be shortened.

After allowing the permanent finishing agent to act for a predetermined period of time, the hair is thoroughly washed with water while still wrapped in curlers.

In a second step, the hair is treated with an oxidizing agent, preferably a bromate solution or a hydrogen peroxide solution, to achieve shape fixation. This causes the disulfide crosslinks of the hair keratin that were previously cut to be recombined in a new form. The action time of the fixative on the hair is generally about 10 to 15
It's a minute.

Next, remove the curlers and wash your hair thoroughly with water.

However, in the case of the above-mentioned permanent hair processing method, there are many difficulties in working with a permanent processing agent solution and a fixative solution. Even if the work is carried out with particular care, it is difficult to avoid the processing liquid from adhering to the scalp or hands of the barber, resulting in problems such as skin damage. In other cases, the permanent processing solution or fixative solution may run down from the hair, making it impossible to achieve the processing objective.

Therefore, attempts have been made to thicken permanent finishing agents and fixatives to make them gel-like or cream-like.

However, for various reasons, we have not yet reached the stage where thickened permanent finishing agents or fixatives are actually used. In particular, since these preparations contain thickeners, they cannot penetrate into the inside of curly hair sufficiently, and furthermore, in the case of the above-mentioned permanent processing method, the operation is rather difficult. That is, when the thickening permanent finishing agents that have been provided so far are used, the hair becomes smoother, so that the hair coated with this agent can be wound in curlers.

In addition, most of the thickening permanent finishing agents or fixatives that have been provided so far have the disadvantage that they are difficult to remove from the hair even after washing.

Furthermore, alkaline thickening permanent finishing agents, such as those containing gelatin as a thickening additive, have poor storage stability. Moreover, the addition of gelatin reduces the processing capacity of the processing agent.

However, here, A) (1) cationically activated cellulose and/or polytrimethylammonium methyl methacrylate, or (1) polyacrylic acid, polymethacrylic acid, carboxymethylcellulose and/or alginic acid, is added to 0. B) 0.1 to 3.0 ethanolamides and/or isopropanolamides of one or more saturated and/or unsaturated fatty acids containing 12 to 18 carbon atoms; Weight%-C) The following general formula (1) or (II)
D) 0.05 to 0.8% by weight of an amphoteric surfactant comprised of D) 0.05 to 0.8% by weight of dimethylammonium betaine, a fatty acid having 12 to 18 carbon atoms in the fatty acid residue; Permanent processing fluids for reduction or oxidation processes, characterized in that they contain 1.5% to 1.5% by weight in combination, do not exhibit the above-mentioned drawbacks,
It has been found that it is possible to easily provide a thickened permanent processing fluid.

The pH of the permanent finishing agent according to the present invention is adjusted within the range of weakly acidic to neutral to alkaline. Patent, ammonia, monoethanolamine.

It is desirable to adjust the pH value to 5 to 10 using ammonium carbonate and/or ammonium hydrogen carbonate.

The amounts of reducing compounds contained in the permanent treatment agents described herein are those commonly employed in hair treatment. For example, in the case of ammonium salts of thiochlorocholic acid or thiolactic acid, Ln (12% by weight)

The oxidizing agent can be used in combination with other known additives.

It goes without saying that the treatment agents according to the invention may contain the usual additives contained in permanent treatment agents or fixatives, such as hair conditioning agents, hair protectants, dyes, perfume oils, and the like. These additives may be added in amounts that do not substantially impair the effectiveness of the processing agent.

The aqueous permanent finishing agent for the reduction or oxidation process in the permanent finishing of hair according to the present invention comprises:
It penetrates well into the inside of curled hair, does not run off from the hair, and can be easily washed away. Furthermore, when using the treatment agent for the reduction step in permanent treatment according to the invention, the hair does not become too slippery. Furthermore, it goes without saying that the processing ability of the processing agent is inhibited by the presence of the thickening components A to D. However, the feature of the permanent processing agent or fixative according to the present invention is that the components A to D It can only be obtained by using within the percentage range. For example, if component A is used at a concentration above a certain weight percent, the degree of penetration into the inside of curled hair will definitely decrease. When component B is used in concentrations above a certain weight percent, it causes skin damage. Components C and D have the function of further increasing the viscosity of the processing agent,
In this case, the same components act synergistically, and component C or component D alone cannot exert sufficient effects. Components C and D
In addition to the above-mentioned functions, it also functions as a wetting agent, thereby ensuring sufficient permeability of the processing agent.
