TECHNICAL FIELD OF THE INVENTION
The present invention relates to a first agent for permanent waving which can be used for human hair and animal body hair, and more specifically, a first agent for transparent gel-like permanent waving which can be used as a straightening agent for straightening hair and the like. About.
[0002]
Problems to be solved by the prior art and the invention
A commonly used permanent wave agent is prepared by adding an alkaline agent such as ammonia, monoethanolamine or triethanolamine to an aqueous solution mainly containing a reducing agent such as thioglycolic acid and adjusting the pH to 6 to 10. An aqueous solution of an oxidizing agent such as sodium bromate or hydrogen peroxide was used as a second agent.
[0003]
It is important that the agent for permanent wave first adheres easily and evenly to the hair, and in particular, the first agent for straightening hair forms a hair bundle in order to prevent curling at the time of application, Since it is essential to be in a straight state, the dosage form of the first permanent wave preparation has conventionally been cream type.
[0004]
However, the first agent of the cream type permanent wave agent had good usability such as finger rubbing at the time of rinsing after application, but the oily feeling remained even after rinsing, and the touch surface after rinsing was often unsatisfactory.
[0005]
Therefore, in recent years, a gel type product having improved ease of rinsing has appeared on the market. However, when rinsing after application, the feeling of use such as finger passing is poor, and the feeling such as squeaking of hair is heavy.
[0006]
In addition, it is difficult to arbitrarily control the viscosity when preparing the gel type permanent wave agent 1st agent. For example, it is difficult to secure the dosage form with a general thickener, Even if a dosage form can be ensured by incorporating a thickener, the feel becomes poor, such as heavy elongation and stickiness. As for the stability over time, the thickener causes agglomeration, hardening, and in some cases, separation. Thus, the gel type was very difficult to stabilize the dosage form as compared with the cream type.
[0007]
On the other hand, the first gel type permanent wave agent, which is mostly opaque in appearance, has little discrimination and is expected to develop a product which gives a user a visually satisfactory impression. Had been rare.
[0008]
[Means for Solving the Problems]
In view of the above circumstances, the present inventors have studied a suitable gelling agent in the first permanent wave preparation containing thioglycolic acid and / or a salt thereof as a reducing agent. The first agent for permanent wave preferably has an appropriate thixotropic viscous property. In order to impart such viscous properties, a means of blending a water-swellable clay mineral is conceivable. However, in the case of the gel-like permanent wave agent 1 only containing thioglycolic acid and / or a salt thereof and a water-swellable clay mineral, an extreme decrease in viscosity and separation occurred in a short time.
[0009]
Therefore, the present inventors have conducted further intensive studies, and as a result, by blending a polycarboxylate-based polymer surfactant with a composition containing thioglycolic acid and / or a salt thereof and a water-swellable clay mineral, The present inventors have solved the problem of the stability of the dosage form, found that a first agent for a transparent gel permanent wave agent having excellent usability and feeling of use and having a sufficient permanent effect can be obtained, thereby completing the present invention.
[0010]
That is, claim 1 of the present invention provides (A) one or more kinds selected from the group consisting of thioglycolic acid and its salts, dithioglycolic acid and its salts, (B) a water-swellable clay mineral, and ( C) A transparent gel-like permanent wave agent first agent comprising a polycarboxylate-based polymer surfactant.
