Description

Hair care composition

The present invention relates to a hair care composition, which is a composition for utilizing light energy and having hair dyeing and hair care functions, comprising: a hair care base, 0.3% by weight to 5.0% by weight of a silver salt (excluding Silver halide), 0.2% to 20.0% by weight of amino acid, and/or 0.2% to 20.0% by weight of aminosulfonic acid, and/or 0.2 to 30.0% by weight of polyol bitter tea extract, And a surfactant of 0.2 to 5.0 wt.%, the surfactant is selected from the group consisting of an amino acid type surfactant or a saccharide-modified oxoxane type surfactant or a mixture thereof, and wherein the amino acid is not reduced Amino acid and thiol acid. The hair care composition formulation according to the present invention can achieve the advantages of a hair care composition which does not damage the skin and hair and which has a hair dyeing effect.

In general, dyeing materials include not only acid dyes, but also hair dyes made of silver salts. The silver salt-containing hair dye is prepared by using the first liquid of the sodium sulfide aqueous solution and the second liquid containing the silver nitrate aqueous solution, or the first liquid containing the potassium sulfide alcohol solution and the second liquid containing the silver nitrate aqueous solution. Made of. When using, first wet the hair with a brush on the first liquid, then apply the second liquid to the hair with another brush, and attach the black silver sulfide to the keratin on the surface of the hair to blacken the hair. . However, when such a hair dye prepared by using the silver-containing salt is dyed, a stench (hydrogen sulfide) such as a spoiled egg adheres to the hair, and although the malodor can be removed by washing with water, it is obviously not a user. The preferred hair dye will be selected.

There are various additives such as silver halide and color developing agent as hair dye preparations. The dyeing materials of the added components are prepared in a two-dose form and a single-dose form, and a reducing substance is used as a color developing agent, such as an amino acid such as glycine.

There are also single-agent hair dyes which are prepared by emulsifying a water-soluble component such as propylene glycol, methylparaben or purified water with a surfactant such as polyoxyethylene stearyl ether in liquid paraffin, and further mixing boric acid. The beeswax is formed into an emulsion, and an aqueous solution of any one of the ligand ions of silver lactate, silver nitrate, silver fluoride, and silver is added thereto to prepare a single-dose hair dye of the emulsion. After the hair dye is applied to the hair, it is shampooed after being exposed to sunlight in a normal living environment for a day, and the color on the hair will be an unnatural color of copper brown, and then, even after shampooing every day, after 20 days No changes in hair coloring conditions were observed.

The characteristics of the above-mentioned hair dye base are as follows: a general hair conditioner such as a hair conditioner or a hair rinse is used in a large amount of stearyltrimethylammonium chloride and docosane. A cationic surfactant having a long-chain alkyl chain such as trimethylammonium chloride, and exhibiting its properties. The above cationic surfactant may also be added in a small amount in a hair dye which is commercially available using light energy. It is possible to add 1 wt% or less of the above cationic surfactant to a general hair cream, and by adding these cationic surfactants to a hair cream and mixing with a higher alcohol, the oil phase can be reduced. Ingredients to provide a product that has the advantage of plasticity (the advantage of force does not make the hair sticky and uncomfortable. However, when using a single-dose type of hair dye containing silver salts, it may be used together with the above formula. This is because the silver-containing salt in the base composition of the hair dye paste reacts with the chloride ion as the counter ion of the cationic surfactant to produce silver chloride, which is extremely light like the photosensitive material used for photography. Sensitive, so when silver-containing salts slowly penetrate into the hair from the cream, and before the reduction and fixed color development, it will be quickly reduced in the cream phase as silver or silver oxide, etc. as black particles. Therefore, although the hair Appearance The hair is blackened, but since these black particles can be washed away by shampoo and hardly remain on the hair, they are not suitable for use in a single-dose hair dye base. Therefore, when a cationic surfactant such as an alkyltrimethyl chloride-based cationic surfactant such as a chloride ion (further ion) is used as a counter ion, the amount of addition is significant in order not to reduce the dyeing power of the dyeing material. restricted. When such an amount of addition is limited, there is a possibility that the performance cannot be sufficiently exerted in terms of softness or moldability against hair. The appearance of black particles of silver occurs not only when an alkyltrimethylammonium chloride-based cationic surfactant is used but also in the presence of a halogen ion. Further, this phenomenon occurs more quickly when the silver-containing salt used is easily soluble in water.

Further, it is generally known that a substance as a reducing agent is not suitable for addition to a single-dose hair dye using light-containing energy using a silver-containing salt. This is because if the silver-containing salt is coexisted with a strong reducing substance such as sulfur-containing reducing amino acid such as ascorbic acid, sulfite or cysteine in the hair dye, the silver-containing salt is instantly reduced. The black silver particles are precipitated, so that their hair dyeing ability is significantly reduced. If a reducing substance having a weak reducing power coexists with a silver salt, the degree of change will vary depending on the amount of addition and the state of storage, but the state of the hair dye will also change over time. Variety. Thus, since the hair dyeing effect of the hair dye is lowered with the passage of time, even if a weakly reducing substance is added, it is not preferable to adding it to a single-dose hair dye base using light energy using a silver salt. in. Further, when a single-dose hair dye to which a sulfur-containing amino acid such as methionine is added is applied to the hair, an unpleasant odor of sulfur is generated, which causes a user to feel uncomfortable. Further, the hair dye to which the thiol-containing acid was added was not able to form silver sulfide on the hair, and it was not found to have an effect of dyeing the hair to a brown to black gray color which is the object of the present invention.

Since the single coloring power of commercially available hair dyes is weak, it is necessary to repeat the application a plurality of times, which is very troublesome for the user. In view of the above disadvantages of hair dyes, the present invention is a hair care composition. The most important thing is to increase the hair dyeing effect by adding a silver salt (excluding silver halide) to the hair care cream base, and using an amino acid, and by using an amino acid (excluding the reducing amino acid and the methyl amide) Different combinations of acid and other sulphur-containing amino acids and addition ratios, so that the color tone and hue have a certain range, and the special surfactant is used to enhance the dyeing strength and the leveling property, and the bitter tea oil extract of the polyol is used as the Hair care ingredients, combined with hair dye and hair care.

Further, the hair care composition of the present invention is easy to handle, and further, the present invention has the advantage that the silver-containing salt can be firmly attached after being applied to the hair by direct sunlight for 30 minutes or more. On the hair, the color is maintained for a long time (about 2 months to 3 months), even if it is compared with permanent hair dye, it can dye white hair into a natural color suitable for white hair - from brown to grayish black. When a specific surfactant is added to the hair cream composition of the present invention, the stability of the hair dye can be further improved, and the hair care product of the present invention is quite industrially useful.

Chromatic aberration, and the results are recorded in Table 3.

CIB LAB is based on the theory that a color cannot be both green and red, and not both blue and yellow. Therefore, a single value can be used to describe the red/green, yellow/blue features. The CIB LAB tolerance formula is centered on the standard and then given individual L*a*b* values, positive and negative (+/-) error ranges.

△L*=L* sample-L* standard (lightness difference, + shallow)

△a*=a* sample-a* standard (+ reddish, - greenish)

△b*=b* sample-b* standard (+ yellowish, - bluish) One of the important indicators for dye dyeing performance evaluation is the dyeing depth. The Kubelka-Munk staining depth equation establishes a certain functional relationship between the absorption coefficient K and the scattering coefficient S of the measured object and the concentration C of the colored substance in the solid sample. The larger the K/S value obtained by calculation, the deeper the surface color of the solid sample, that is, the higher the concentration of the colored substance, the better the dyeing performance of the dye. The color change (before and after the weathering test) is the ΔE (DE) value. DE is calculated using the following equation, based on the L, a and b values (reflected values) of the CIE system: [(ΔL) ² + (Δa) ² + (Δb) ² ] ^1/2 = △ E (DE) . The following sample K/S values were calculated from the instrument, where K = absorption, S = scattering, R = reflection in the case of minimal reflection: K / S = (1-R) ² /2R in the sample instrument, The K/S value is measured at the minimum reflection wavelength. The instrument conditions are: CIE lab, D65 source, 10 degree observation angle, including spectral composition (SCI), small area observation (SAV), scanning wavelength = 400 ~ 700nm. The higher the K/S value, the deeper the chromaticity. dE*(ab) shows the dyeing property. The smaller the value, the smaller the color difference, the better the uniformity, and the better the dyeing effect.
