Description

  The present invention relates to a reducing composition for subjecting hair or the like to a hair deformation treatment such as permanent wave or straight permanent. More specifically, the present invention relates to a reducing composition capable of exerting a hair deforming (hair thinning or straight hairing) action while suppressing damage such as offensive odor and hair.

As a method of deforming the shape of the hair, a method of applying a permanent wave or a straight permanent is generally known.
As a treatment method, first, one agent containing a reducing agent, an alkali and the like is applied to the hair to cut hydrogen bonds, ionic bonds, and disulfide bonds of proteins in the hair. Thereafter, the hair can be formed into a desired shape, and the hair and the straightness can be formed by re-forming a cut bond with two agents containing an oxidizing agent.

  Ammonium thioglycollate is widely used as a reducing agent used in the first agent, but it is highly damaging to the hair due to its high reducibility, and the odor caused by thioglycolic acid causes the practitioner, the practitioner, etc. There is a problem of making you feel uncomfortable.

  On the other hand, as a treatment method for simultaneously performing permanent treatment and dyeing treatment of hair, a method of adding a color former to a permanent solution (Patent Document 1), and an oxidation dye instead of an oxidizing agent used for permanent wave or straight permanent A method using a coloring agent is known (Patent Document 2).

[Hair treatment method]
The method of treating the hair using the reducing composition of the present invention includes the steps of applying the reducing composition to the hair, leaving it for 5 minutes or more, and washing out the reducing composition. It is a method.

The step of applying the reducing composition to the hair comprises wetting or drying the reducing composition containing the (A) polyphenol and (B) 0.1 to 2.5% by mass of ammonium thioglycolate. It is a process of applying to the hair using a comb or the like.
When it is desired to make the hair straight, combing may be performed so that the hair becomes straight, or a process of stretching the hair with an iron or the like may be performed. On the other hand, when it is desired to curl or wave the hair, the hair may be wound around a rod or the like to form a gentle shape.

  The step of leaving for 5 minutes or longer is to apply the above-mentioned reducing composition to the hair and then leave it at room temperature or in a heated state. In general, treatment at a temperature above room temperature makes it easier to change the shape of the hair. The room temperature in the treatment method of the present invention indicates a temperature in the range of 20 ° C. ± 15 ° C., and the heating state indicates a range of 35 to 45 ° C.

  The step of washing away the reducing composition is a step of washing the reducing composition applied to the hair with tap water, purified water, carbonated water or the like. By using carbonated water or the like, it is possible to obtain a massage effect on the scalp at the same time as washing off.

  Furthermore, as a method of treating hair, in addition to the above-mentioned method of treating hair, a step of treating the hair with an oxidizing composition may be included. The oxidizing composition is a composition containing a keratin oxidizing substance, and is for recombining a disulfide bond cleaved by the reducing composition. Examples of the oxidizing composition include a second agent of an oxidative hair dye composition, a second agent of a hair decolorizing agent, and a second agent of a perming agent. In the case of treatment with an oxidizing composition, it is also possible to carry out the subsequent treatment without washing away the above-mentioned reducing composition.

Moreover, it can confirm that it is inferior to the damage suppression property of hair, and the odor suppression effect of Comparative Example 4 which contains 3 mass% of ammonium thioglycollate although what contains polyphenol.

  It is understood from Table 2 that Comparative Example 6 using ascorbic acid having no phenolic hydroxyl group and Comparative Example 7 using vanillin having two or more phenolic hydroxyl groups are inferior in straightness. it can. On the other hand, while the reducing composition of the Example containing a polyphenol can suppress the damage and odor of hair, it can exhibit the outstanding straightness.

  When the hair dyeing property, the color changing property and the lightness evaluation of the examples and the comparative examples were confirmed, it is difficult for the reducing composition using the coloring acid as polyphenol to affect the hair dyeing property and the like. I understand.

  The reducing composition of the present invention can be used as a permanent waving agent or a straight permanent agent in a beauty salon, a barber shop or the like.

  In addition, the hair treatment method using the reducing composition of the present invention can be used for permanent wave treatment of hair, straight permanent treatment, etc. in a beauty salon or a barber room.
