Description

  The present invention relates to a hair dyeing composition using henna, and more particularly to a composition capable of developing a stable finished color after hair dyeing.

  Synthetic dyes such as p-phenylenediamine-based and aminophenol-based oxidative dyes have been widely used as dye components because the hair-dyeing composition has excellent hair dyeing power and can express various color tones. However, it has been pointed out that this type of oxidation dye is concerned about skin damage, is an environmental hormone that adversely affects the ecosystem, and is concerned about carcinogenicity and allergenicity.

  On the other hand, direct dyes such as HC dyes and basic dyes that are considered to be highly safe are also used. Hair dyes using direct dyes can be dyed in the neutral range, so there is no damage to the hair due to alkali, and no oxidants such as hydrogen peroxide are needed. There is no fear of an accident caused by entering the hair dye, and it is a relatively safe hair dye compared to a hair dye using an oxidative dye.

  For example, since HC dyes and basic dyes are dyed on the hair without causing a chemical reaction, even if the hair is repeatedly dyed, there is little damage to the hair. However, the dyeing effect is poor in sustainability, and color fading easily occurs by repeating shampooing.

  Recently, henna has attracted attention as a dye. Henna contains 2-hydroxy-1,4-naphthoquinone as an active ingredient, and is a natural orange-brown system that is obtained by drying and pulverizing the leaves of Lawsoniainermis, which is a shrub of the family Lamiaceae produced in tropical regions such as India and Iran. It is a dye.

  For example, a creamy hair dye composition containing 1 to 40% by weight of henna powder and / or henna extract and containing moisture, oil, activator, treatment agent, HC dye, and basic dye is proposed. (Patent Document 1).

  In addition, a hair dye is proposed in which 20 to 90% by weight of henna powder and 80 to 20% by weight of dry powder of Indian indigo leaves are mixed and kneaded with water to be used as a paste (patent). Reference 2).

JP 2010-1278 A Japanese Patent Laid-Open No. 2003-300845

  For hair dyes based on henna powder, apply a hair dye paste to the hair and heat it at a temperature of about 30 ° C. to 35 ° C. for about 10 to 30 minutes, or cover it with a cap to remove moisture. After holding for about 1 hour while preventing evaporation, it is shampooed and dried with a dryer. However, it takes time until stable color development, and a stable finished color cannot be confirmed until several days have passed after hair dyeing.

  In view of such problems, an object of the present invention is to provide a hair dyeing composition capable of developing a stable finished color immediately after hair dyeing in a hair dye using henna.

  Therefore, the hair dye composition according to the present invention was blended with 0.0075 parts by weight to 0.015 parts by weight of titanium dioxide powder having calcium phosphate fine particles and silk fine particles adsorbed on the surface to 100 parts by weight of henna powder. It is characterized by.

  One of the characteristics of the present invention is that titanium dioxide powder having calcium phosphate fine particles and silk fine particles adsorbed on the surface is mixed with henna powder.

  Titanium dioxide powder with adsorbed calcium phosphate fine particles and silk fine particles exhibits a photocatalytic reaction with visible light, particularly light with a wavelength of 450 nm or more. (Very strong hydrophilicity) can be imparted. Polyphenols, which are the main components of henna, penetrate rapidly into the hair due to the superhydrophilicity of the hair surface and bind to the hair tissue and exhibit a finished color, so that a stable finished color can be developed immediately after dyeing. it can.

  The amount of calcium phosphate fine particles is 1 to 25 parts by weight with respect to 100 parts by weight of titanium dioxide, and the amount of silk fine particles is within the range of 0.1 to 2.5 parts by weight with respect to 100 parts by weight of titanium dioxide. And Silk fine particles are said to have a function of promoting adsorption of calcium phosphate while crystallizing on the surface of titanium dioxide.

  Here, with respect to 100 parts by mass of henna powder, the titanium dioxide powder having calcium phosphate fine particles and silk fine particles adsorbed on the surface was made 0.0075 parts by weight to 0.015 parts by weight. This is because it is not sufficiently imparted, and even if it exceeds 0.015 part by weight, the hydrophilicity is not increased any more and is wasted.

  The hair dye composition according to the present invention has dyes for developing various colors, such as natural indigo, turmeric, walnut shell, tea leaves, roses, persimmon leaves, coffee seeds, lemon peels, HC dyes, or two of them. The above may be used, and a stable finished color can be developed immediately after hair dyeing. These dyes are considered to be fixed to the hair by polyphenols, which are the main components of henna, to stabilize the color development and make it difficult to lose color.

  Furthermore, cetyl PG hydroxyethyl palmitamide may be added to increase the water retention of hair, and hydrolyzed keratin may be added to increase the affinity for hair dyes.

  When the hair dye composition according to the present invention is used, an appropriate amount of water or warm water of about 70 ° C. is added and kneaded into a paste, the paste is applied to the hair, and the hair surface temperature is 35 ° C. to 40 ° C. The hair can be dyed by heating it to the extent that it is maintained for 10 to 20 minutes, washing the hair to wash away the excess paste adhering to the hair, and drying the hair.

  Moreover, after drying hair, you may make it press-process with the iron press controlled to surface temperature 150-200 degreeC to hair. The iron press can stabilize the dye component in the henna for processing at high temperature and high pressure, and there is almost no discoloration even after repeated shampooing.

  Hereinafter, the hair dye composition according to the present invention will be described in detail based on examples.

Hair dye by blending 1000g of henna powder (made by Modern Chemical Co., Ltd., trade name: Akiraki Henna) with 150g titanium dioxide powder (trade name: Trinity made by Environmental Conservation Laboratories, Inc.) with calcium phosphate fine particles and silk fine particles adsorbed on the surface. A composition was prepared.
This hair dyeing composition is kneaded into a paste with warm water (or water) at around 70 ° C., and the paste cooled to room temperature is applied to the hair (white hair) so that the hair surface temperature is 35 ° C. to 40 ° C. After warming up and holding for 10 to 20 minutes, washing the hair to wash away the excess paste attached to the hair and drying the hair, the whole white hair is finished in natural orange color I was able to dye my hair. Moreover, even after repeated shampooing after dyeing, color fading hardly occurred.

  A hair coloring composition was prepared in the same manner as in Example 1 except that 100 g of titanium dioxide powder on which calcium phosphate fine particles and silk fine particles were adsorbed on the surface, and this composition was kneaded into a paste with water or warm water to make white hair After dyeing the hair, it was possible to dye it in a natural orange color, and this finished color was stable.

  A hair dye composition was prepared in the same manner as in Example 1 except that 75 g of titanium dioxide powder having calcium phosphate fine particles and silk fine particles adsorbed on the surface thereof, and this composition was kneaded into a paste with water or warm water. When the hair was applied, the entire gray hair was dyed to a natural orange color.

  A hair dyeing composition was prepared in the same manner as in Example 1 except that 0.1 g of hydrolyzed keratin and 0.1 g of cetyl PG hydroxyethyl palmitamide were further blended, and this composition was made into a paste with water or warm water As a result of kneading and dyeing, not only was it possible to stably dye the entire gray hair to the natural orange color that was the finished color, but the entire hair was moist and moisturized, and the volume of the hair could be increased.

The composition for hair dyeing described in Examples 1 to 3 was added to the leafhopper leaf, tea leaf, bushoke flower, anmacros fruit, acacia consina fruit, hydrolyzed keratin, cetyl PG hydroxyethyl palmitamide, HC blue 2, HC yellow 4 An appropriate amount of HC Red 3 was blended to prepare a hair dye composition.
When this hair dyeing composition was kneaded into a paste with water or warm water and dyed with the paste, it was chocolate brown, olive brown, cherry red, apricot (however, in this case HC blue 2 was not used).
