Description

[Detailed description of the invention] Industrial applications The present invention relates to hair colorant compositions.

Conventional technology and its problems Conventionally, when applying colorants to hair, etc., first, an applicator such as a brush is moistened with the colorant stored in a container, and the applicator is pulled out from the container and then applied. There was a need. Therefore, the application work is extremely troublesome, and when the applicator is pulled out of the container, the edge of the applicator cannot be avoided from touching the container mouth wall, which causes the colorant to adhere to the outer wall of the container and stain the container. Furthermore, there were problems such as the coloring agent scattering.

Recently, in order to make the work easier, a brush or the like is attached to the tip of a colorant storage container with a built-in valve device, and a knock operation opens the valve port to supply colorant to the tip. A structured applicator has been devised.

However, the inconvenience of the knocking operation still remains, and furthermore, there is a risk that an excessive amount of coloring material may be supplied to the tip and drip or scatter due to excessive knocking.

Therefore, in order to solve the above problem, a fiber bundle core is provided at the tip of a colorant storage container, one end of the fiber bundle core is immersed in the colorant in the container, and the fiber bundle core is removed by capillary action. Containers have been devised that guide and apply colorants to the tip (applying portion) (Utility Model Application Publication No. 1-154830, Utility Model Application Publication No. 1999).
-154831). By using this fiber bundle core container, the coating operation becomes easier and the scattering of the colorant from the coated area can be effectively suppressed, but at the same time new problems arise. In other words, conventional hair colorants are
Because it uses a volatile solvent and dries quickly, if you remove the cap and leave the fiber bundle core exposed to air when using the above container, the colorant will evaporate due to evaporation of the solvent in the colorant. Other components such as pigments and resins continue to dry and solidify. Therefore, there arises a problem that the flow of the internal solution at the application area is obstructed, causing fading of the coating film or failure to flow out.

In order to solve the above problem, there is a method of using slow-drying solvents for colorants with low vapor pressure, but this method significantly deteriorates the performance of the colorant, such as decreasing the drying properties of the paint film and increasing viscosity. Unfortunately, the current situation is that no suitable hair colorant has been developed.

Means for Solving the Problems The present invention solves the above problems, suppresses deterioration in drying properties of colored parts and stability of pigment dispersion, and has an excellent texture.
It is an object of the present invention to provide a hair coloring composition that effectively suppresses drying and solidification at the application area, especially when used in a fiber bundle core type container.

That is, the present invention provides a hair coloring composition containing a pigment, a resin, and an organic solvent, wherein the composition contains (a) -form % formula % (1) [wherein R1 and R2 are the same - or Differently, it represents hydrogen or a stearoyl group. However, this does not apply when both are hydrogen. Monoglycerol stearate represented by (b)-formula [wherein R1 to R5 are the same or different and represent hydrogen or a stearoyl group. However, this excludes the case where all of R1-R5 are hydrogen. a represents 0 or an integer of 1-13. ] Polyglyceryl stearate ester, (c)-formula [wherein R1-R3 are the same as above. However, the case where all of R and -R3 are hydrogen is excluded. ] Sorbitan stearate, (d)-form ( ) [wherein R1-R3 are the same as above, except when R and -R3 are all hydrogen (.

e represents an integer from 1 to 10. ] Polyoxyethylene sorbitan stearate ester, (e)-form [wherein R5 represents a stearoyl group] b+c+d is 1
Indicates an integer between ~10. ] Or in the general formula, R, ~R3 and b+4C+d are 1 to . Indicates an integer of 10. However, this excludes the case where all of R1-R3 are hydrogen. ] Polyoxyethylene sorbitol stearate represented by (f) general formula % formula % ) () [wherein R6 is the same as above. f+g represents an integer from 1 to 10. ] Polyoxyethylene glycerin stearate represented by the following, and (g) general formula [wherein R6 is the same as above. ] This relates to a hair coloring composition characterized in that it contains at least one selected from the group consisting of propylene glycol stearic acid and ester represented by the following.

As a result of intensive research to achieve the above object, the present inventor has discovered that at least one specific compound selected from the above (a> to (f)) is added to the pigment, resin, and organic solvent as a drying inhibitor. When the hair coloring agent obtained by the method is used in the above-mentioned fiber bundle core type container, even if the container is left with the cap removed for a long time, the coloring agent will not dry and solidify, and the initial state will be maintained during subsequent use. without losing performance
We discovered that it can be reused. The present invention was completed based on these findings.

In the composition of the present invention, as a drying inhibitor, (a) monoglycerol stearate represented by general formula (I), (b) polyglycerol stearate represented by general formula (II), (C ) Sorbitan stearate represented by general formula (I[r), (d) polyoxyethylene sorbitan stearate represented by general formula (TV) or (■'), (e) general formula (
V) polyoxyethylene sorbitol stearate represented by, (f) polyoxyethylene glycerin stearate represented by general formula (Vl), and (g) propylene glycol stearate represented by general formula (■). It is essential to use at least one selected type. The purity of these esters, which are drying inhibitors, is not particularly important. For example, even if the fatty acid composition in the ester contains palmitic acid, myristic acid, etc. in addition to stearic acid, the purity If the proportion is about 50% or less, it can be included as a drying inhibitor in the present invention.

The amount of the drying inhibitor used in the composition is 0.05~
About 3.0% by weight, preferably 0.15-1.0% by weight
It is recommended that the range be within the range of .

By controlling the amount used within the above range, drying of the colorant composition can be effectively suppressed without impairing the excellent properties inherent in the hair colorant such as abrasion resistance and hair finish. This drying inhibitory effect is caused by the interaction between the moisture absorbed from the air by the drying inhibitor contained in the colorant composition and the solvent in the colorant composition when the colorant composition is left in the air. This is thought to be due to the action of forming a soft, thin gel-like stable layer on the surface of the colorant composition. This gel layer effectively suppresses evaporation of the solvent and maintains the composition of the colorant composition constant. Furthermore, since the blending ratio of the drying inhibitor is small, the drying rate of the coated film after application is not reduced.

In the present invention, in addition to the above-mentioned drying inhibitor, dyes (pigments), resins, and organic solvents are used as raw materials.

As these pigments, resins, and organic solvents, known substances used as raw materials for hair colorants can be used as they are.

In addition, in the present invention, known additives conventionally used in hair coloring agents such as water, fragrances, acids, alkalis, viscosity modifiers, plasticizers, and dispersants can also be used as necessary. .

The production of the composition of the present invention is no different from the conventional method used for producing hair colorants, except that the drying inhibitor is added to the conventional raw materials. What is necessary is just to mix and adjust a coloring agent composition.

Next, when actually commercializing the composition of the present invention, containers (applicators) used to store the composition of the present invention include, for example, those disclosed in Japanese Utility Model Application Publication No. 1-154830 and Japanese Utility Model Application Publication No. 1-154831.
