Description

In the present invention, the powdered or fibrous pseudo-hair material sprinkled and fixed on the scalp or hair to hide the thinned part of the hair, or further fixed to the head by a spray for fixing the pseudo-hair material. The present invention relates to a pseudo-hair material remover for removing a pseudo-hair material.

Conventionally, pseudo-hair material has been used for the purpose of temporarily covering thin hair and gray hair.
Pseudo-hair material is a fiber or powder that is formed from vegetable fibers such as rayon fibers and cellulosic fibers, pigments such as mica, dimethicone, and zinc oxide, and resembles hair, and is sprinkled on the hair or scalp that you want to apply. To use.

Since these pseudo-hair materials are manufactured so as not to be easily removed by rain or impact in daily life (Patent Document 1), a hair cleaning agent whose main function is to remove stains on hair and scalp is a pseudo-hair material. There is a problem that the hair cannot be sufficiently removed and the hair needs to be washed again, causing damage to the hair.
Further, for the purpose of improving the adhesiveness and durability, a fixing spray containing a film-forming agent or the like may be used after applying the pseudo-hair material. Therefore, there is a demand for a pseudo-hair material removing agent that has a sufficient pseudo-hair material removing effect even when a fixing spray is used.

JP-A-2018-172313

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pseudo-hair material removing agent having an excellent pseudo-hair material removing effect.

〔式（１）中、ＡＯはエチレンオキシ基またはプロピレンオキシ基であり、Ｒ¹、Ｒ²及びＲ³は水素または−ＣＯ−Ｒ⁴で表される基であり、Ｒ⁴は炭素数７〜１７の炭化水素基であり、ｌ＋ｍ＋ｎの平均値は６〜８である。〕 As a result of research, the present inventor has made a pseudo-hair material containing at least one selected from the group consisting of (A) fatty acid polyglyceryl and a compound represented by the following general formula (1), and (B) polyhydric alcohol. It has been found that the remover achieves the above objectives.

Wherein (1), AO is an ethyleneoxy group or propyleneoxy group, R ^1, R ² and R ³ is a group represented by hydrogen or -CO-R ^4, R ⁴ is 7 carbon atoms There are 17 hydrocarbon groups, and the average value of l + m + n is 6 to 8. ]

Further, a pseudo-hair material removing agent containing (C) an anionic surfactant and (D) amphoteric surfactant, and at least one polymer selected from (E) cationized polymer and (F) amphoteric polymer is the above object. Found to achieve.

According to the present invention, it is possible to provide a pseudo-hair material removing agent having an excellent effect of removing the pseudo-hair material, and further having excellent foaming during washing and finger passage after the hair is dried.
Hair cleaning agents (shampoos) that are generally used when washing hair are for removing sebum stains and stains that adhere to daily life such as dust, dust, and sweat.
On the other hand, pseudo-hair is a pseudo-hair material because it is made of colored vegetable fibers such as rayon and cellulose as described above, and powdered inorganic pigments such as zinc oxide and mica. The removing agent needs to have an action of washing away all these components, which is difficult to achieve with a hair cleaning agent.

Further, the pseudo-hair sometimes has a fixing component contained in the fixing spray, and a general fixing spray includes an acrylic resin alkanolamine solution (for example, (alkyl acrylate / diacetone acrylamide) copolymer AMP). Since the film-forming polymer of No. 1 is contained as a fixing component, it is necessary to wash and remove these components as well.
That is, the present invention relates to a removing agent that is particularly suitable for removing pseudo-hair material that is completely different from the hair to be washed, has an excellent effect of removing the pseudo-hair material, and has good foaming during washing.
