Traditionally, acidic dyes were used as the dyes contained in hair dye compositions, but with the relaxation of cosmetic regulations in 2001, it became possible to use basic dyes and HC (hair color) dyes. . When using oxidative dyes and acid dyes, which have been used in the past in addition to the above dyes, for hair dyeing, various studies have been conducted to improve dyeability and usability.
For example, Patent Document 1 describes a cationic surfactant (A) having methosulfate ion as a counterion, a cationic polymer (B), and one type selected from basic dyes (C1) and HC dyes (C2). A hair dye composition containing the above dye (C) is described, and it is described that it can have excellent hair dyeing properties, operability, and storage stability.
Furthermore, Patent Document 2 describes a hair dye composition containing the following components: (A) a direct dye, (B) a sulfonated polysaccharide, and (C-1) a cationic polymer having a charge density of 3 meq/g or more and 24 meq/g or less. It is described that it has good dyeability and color fastness, has an excellent effect on improving the feel after treatment, maintains an excellent feel even after repeated shampoo washing, and is stable in hair dyeing without producing any precipitates. It is described that it is a drug composition. Specifically, a diallyl quaternary ammonium salt polymer is used as the cationic polymer.
本発明の目的は、染色性を向上させることが可能な新規な毛髪処理剤を提供することにある。また、本発明の別の目的としては、染毛時の褪色抑制効果を有する毛髪処理剤を提供することにある。 An object of the present invention is to provide a novel hair treatment agent that can improve dyeing properties. Another object of the present invention is to provide a hair treatment agent that has an effect of inhibiting fading during hair dyeing.
本発明者らは、上記のような問題点に鑑み検討を行い、ポリアルキレンイミン含有毛髪処理剤が、染毛時の褪色抑制効果に優れることを見出し、本発明を完成させた。 The present inventors conducted studies in view of the above-mentioned problems and found that a hair treatment agent containing polyalkyleneimine has an excellent effect of suppressing fading during hair dyeing, and completed the present invention.

[Example 1]
Creating dyed hair bundles:
At 25℃, 3g of oxidized hair dye (Ordeve Ash 9-10 (manufactured by Milbon)) was evenly applied to 1g of dried yak hair strands, left at 45℃ for 15 minutes, and then washed with tap water. The hair was thoroughly rinsed for 1 minute, towel-dried, and then dried with a hair dryer to obtain a dyed hair bundle. The L1* value, a1* value, and b1* value of this dyed hair bundle were directly measured using a spectrophotometer CM-5 manufactured by Konica Minolta.
Creating washed hair bundles:
The dyed hair bundles were treated with polyethyleneimine (weight average molecular weight 350,000, amine value 18 (mmol/g.solid), amine grade ratio (primary/secondary/ Amphitol 55AB (cocamidopropyl betaine, manufactured by Kao Corporation) was added to a 3.3% by mass aqueous solution (adjusted to pH = 5 using succinic acid) at 40°C. After soaking for 30 minutes, the hair was thoroughly rinsed with tap water for 1 minute, towel-dried, and then dried with a hair dryer to obtain a washed hair bundle. The L2* value, a2* value, and b2* value of this washed hair bundle were directly measured using a spectrophotometer CM-5 manufactured by Konica Minolta.
The color difference (color difference at first washing) (ΔE) between the dyed hair bundle and the washed hair bundle was calculated as follows. The results are listed in Table 1.
