Description

  The present invention is a shampoo for dyeing hair which has an effect of preventing discoloration when washed hair dyed by treatment with a hair dye composition, has a low irritation, is excellent in feeling of use, and has an excellent pearly luster. Relates to the composition.

  In recent years, with the increase of middle-aged and older people and the increase of young people who suffer from gray hair, there is an increasing demand for hair coloring of natural white hair. In addition, for young people, there is a growing demand for black hair to have a maroon or brown shade for fashion reasons. For this reason, many products such as hair color, color rinse, color treatment, and color mousse are commercially available. Such products use the principle of changing the color tone of hair by adsorbing direct dyes such as oxidative dyes and acid dyes to the hair, so that the detachment and discoloration of the dyes occur due to daily hair washing, and hair dyeing There is a disadvantage that the color just after does not last long.

  In order to solve such problems, many attempts have been made to maintain the color by blending a dye into a shampoo and leaving the dye in the hair during hair washing (see Patent Document 1, Patent Document 2, Patent Document 3, etc.). However, none of these proposals pay attention to prevention of detachment or discoloration of dyes already adsorbed to the dyed hair, and the detergent composition is excellent in color fading prevention effect focusing on these. There are few proposals for.

  Patent Document 4 discloses a surfactant having a carboxylic acid residue as a detergent composition for hair subjected to hair dyeing treatment capable of preventing color fading when washing hair dyed by treatment with the hair dye composition. And a hair-cleaning composition with a hair dyeing treatment having a pH of 3.0 to 7.0 has been proposed. Specific examples of surfactants having a carboxylic acid group include sulfosuccinic acid surfactants, acyl glutamic acid surfactants, carboxybetaine surfactants, and acylated peptide surfactants. However, the color fading prevention effect of these disclosed techniques is not sufficient, and further improvement has been desired.

  In addition, for the purpose of increasing the added value of shampoo, body shampoo, rinse, etc., these appearances are made pearly. Conventionally, as a method for making the appearance pearly, a method of crystallizing crystals such as ethylene glycol fatty acid ester has been taken. A liquid detergent composition containing a surfactant having a carboxylic acid group according to Patent Document 4, particularly an N-acylamino acid surfactant such as an N-acylglutamic acid surfactant and an acylated peptide surfactant, It was difficult to make pearl luster appear by blending solid ethylene glycol fatty acid ester or the like at room temperature.

On the other hand, in Patent Document 5, by blending an inorganic salt, a liquid detergent composition containing an N-acylamino acid-based surfactant is blended with a solid ethylene glycol fatty acid ester or the like at room temperature so that pearl luster appears. Although the technology has been disclosed, there has been a possibility that problems may arise in compatibility with high-molecular compounds that are frequently used as conditioning agents and setting agents in recent years and in low-temperature stability.

  Sample preparation and performance evaluation were performed according to Table 1 and Table 2 below.

Each sample is placed in a container equipped with a stirrer in the proportions listed in the table, stirred and heated to 80 ° C, aged for 10 minutes, and then cooled to 40 ° C while giving the same stirring speed to each sample. A sample was used.
Various samples were evaluated for appearance test, low-temperature stability, viscosity measurement, and color fading prevention effect for various samples by the following methods.

Appearance test About 20 g of each sample is taken in a petri dish having a diameter of 8 cm, and the state of the solution is observed.

  The surface is glossy, and when the sample is stirred with a glass rod, it is judged that the stripes are observed due to the orientation of the crystal that causes the gloss to appear along the locus of the glass rod, and the streaks due to the orientation cannot be seen. The thing or the thing which is not clear was judged as a cloudy state.

Low-temperature stability— The properties after storage at 5 ° C. for 1 week were measured and observed.

Viscosity was measured with a B-type viscometer (Toki Sangyo Co., Ltd., TV-10 viscometer, measured at 25 ° C.).

Anti-fading effect White hair bundle (BM-W, manufactured by Beaulux Co., Ltd., 10cm in length, 1g in weight) with a 2% aqueous solution of POE (3) sodium lauryl ether sulfate (Eoal 20C, manufactured by Kao Corporation) After thoroughly washing, it was dried with a hair dryer. After drying the hair bundle with a commercially available hair dye (made by Shiseido Co., Ltd., trade name: masheri lasting hair color, color: sheer ash or stylish red) It was washed with water and dried with a hair dryer. A solution obtained by diluting 2.5 g of each shampoo to 100 ml with distilled water was poured into a sample bottle with a capacity of 100 ml, and the dyed hair bundle after drying was packed, sealed with a lid, and shaken at room temperature for 7 days. After the shaking, the lid was opened, the dyed hair bundle in the sample bottle was taken out, washed thoroughly with water and dried with a hair dryer. The color difference (ΔE) of the dyed hair bundle after drying was measured with a color difference meter (Nippon Denshoku Industries Co., Ltd., Spectrophotometer SE 2000). It is determined that the smaller the ΔE value, the higher the color fading prevention effect.

  Table 1 contains the same amount of the fatty acid glycol ester, which is the third component of the present invention, and the hydroxyalkyl polyhydric alcohol ether compound, which is the fourth component, and the types and amounts of anions and amphoteric surfactants that are the main ingredients of the cleaning component. This is a result of changing. The pearl state is confirmed in all samples, and it can be seen that the combination of the fatty acid glycol ester and the hydroxyalkyl polyhydric alcohol ether compound tends to be in the pearl state. The color fading prevention effect is excellent when the combination of an N-acylamino acid and a specific amidoamine-type amphoteric is excellent, but the mixing ratio of the specific amidoamine-type amphoteric and N-acylamino acid is in the range of 9/1 to 5/5. Particularly excellent color fading prevention effect can be obtained.

  Table 2 shows that the combination of the N-acylamino acid having the most excellent anti-fading effect in the experimental group of Table 1 and the specific amidoamine-type amphoteric combination is constant at a weight ratio of 0.22: 0.78 to form pearly luster. It is the result of blending a certain amount of fatty acid glycol ester and changing the type and amount of nonionic surfactant. The anti-fading function is maintained by both changes of nonion, and both are excellent, but nonionic surfactants with suitable viscosity as shampoo, pearly luster and excellent low-temperature stability are specified by the present invention. It can be seen that this is only the hydroxyalkyl polyhydric alcohol ether compound.

  The shampoo composition for dyed hair of the present invention is useful because it is in a good pearl state, exhibits an appropriate viscosity, is excellent in low-temperature stability, and is excellent in color fading of a hair dye.
