JP6927487B2 - Anti-fading agent for dyed hair and hair composition containing it - Google Patents

Description

The present invention relates to a fading inhibitor having an excellent inhibitory effect on the fading of dyed hair, particularly the acceleration of fading caused by free residual chlorine contained in tap water, and a composition for hair containing the same.

In recent years, coloring that changes the color of hair to various colors to make the hair look beautiful has been performed regardless of age or sex, and consumers' interest in dyeing hair such as gray hair dyeing and fashionable dyeing tends to increase. Furthermore, the dyeing technology for hair is being improved every day. However, the colored dyed hair should maintain the color like the finish after coloring due to the problem of discoloration, pigment disappearance, pigment elution and other fading due to exposure to ultraviolet rays such as sunlight and repeated hair washing treatment in daily life. Has a difficult problem (Patent Document 1).

In order to maintain the color of dyed hair after coloring, a technique using a carboxybetaine type amphoteric tenside agent and a sugar-based non-surfactant (Patent Document 2), ether carboxylic acid and its salt, alkyl glucoside, sterol A technique using a derivative (Patent Document 3) and a technique using an amide betaine type amphoteric surfactant and an anionic surfactant (Patent Document 4) have been reported. However, these were insufficient in that the fading of the dyed hair could not be sufficiently suppressed in the hair washing treatment and that the pigment elution from the dyed hair was insufficiently suppressed.

Elimination of free residual chlorine by a fading inhibitor 1. Outline of the test The free residual chlorine scavenging action of the fading inhibitor of the present invention was evaluated.

2. Experimental method 10 μL of the fading inhibitor of the present invention diluted with purified water and 890 μL of tap water were mixed in a test tube. Then, 100 μL of Rapid DPD reagent (Kanto Chemical Co., Inc.) prepared at 100 mg / mL was added, mixed well, and then the absorbance at 510 nm was measured with a microplate reader and calculated as the elimination rate.
As a fading inhibitor, peach leaf extract (trade name: peach extract BG), Shinanoki extract (trade name: Shinanoki extract BG-J), Jio extract (trade name: Gio extract BG-J), manufactured by Maruzen Pharmaceutical Co., Ltd., Chimpi extract (trade name: chimpi extract BG), parsley extract (trade name: parsley extract BG-J), senkyu extract (trade name: senkyu extract BG), yukinoshita extract (trade name: yukinoshita extract BG), mussel extract (Product name: Gaio extract BG) and Enmeisou extract (Enmeisou extract BG) were used.

3. 3. Results The results are shown in Table 1. By adding 0.1% of any of the fading inhibitors of the present invention, 50% or more of free residual chlorine scavenging activity was exhibited.

Inhibitory effect of peach leaf extract on fading due to free residual chlorine in dyed hair 1. Outline of the test The fading inhibitory effect of peach leaf extract on the fading of dyed hair by free residual chlorine was evaluated.

2. Experimental method The bleached hair bundle was dyed using a commercially available oxidative hair dye (red) according to the attached instructions. The dyed hair was immersed in purified water as an untreated control and in purified water to which 10% hypochlorous acid was added as free residual chlorine. With these as basic conditions, conditions for the presence or absence of addition of 1% peach leaf extract (trade name: peach extract BG, Maruzen Pharmaceuticals Co., Ltd.) were prepared. The dyed hair is immersed in each solution, shaken for 2 hours, dried with shampoo and a dryer, repeated for 3 cycles, dried, and then the color tone of the dyed hair is measured with a color difference meter (CR-). 13. Konica Minolta HD) was used for measurement. The red index a ^* was evaluated as a color index.

3. 3. Results In purified water, no difference in color was observed with or without peach leaf extract. On the other hand, in the hypochlorous acid-containing solution, a significant decrease in color was observed as compared with purified water, confirming the acceleration of fading due to free residual chlorine. On the other hand, no change in color was observed by adding 1% of peach leaf extract. From the above, it was clarified that the peach leaf extract has a remarkable effect of suppressing fading on the fading of dyed hair due to repeated exposure to free residual chlorine.
