Problems solved by technology
In this way, the decoloring agent or hair dye of the type in which the mixed solution is discharged in a foam form from a non-aerosol foaming container is completely different from the physical properties required in conventionally known liquid or cream-like decoloring agents or hair dyes. , so the formulations used in these previous formulations cannot be used directly
For example, in order to improve the touch after decolorization or dyeing, a large amount of ingredients such as silicone or higher alcohol will be contained in liquid or cream dosage forms, but even if such a formula is converted to a non-aerosol foaming container alone, it cannot spit a good lather

[0094] The first dose with the compounding composition (mass %) shown in Table 1 and the second dose with the following prescription were prepared and put into containers respectively. With the mixing ratio (mass ratio) of the first agent and the second agent as 1:1.5, in a squeeze container (Daiwa Can Seiko Co., Ltd., volume 210mL, mesh size: 150 mesh in the mixing chamber, 200 mesh in the front end, air introduction The total opening area of the narrowest part of the road is 0.27mm 2 , the inner diameter of the suction tube is φ1.6mm) and mix in it, and spit it out in the form of foam.
[0095] The low-temperature stability was evaluated using the first agent, and the foam of the mixture of the first agent and the second agent discharged from the container was used to evaluate "appearance", "hair dyeing property", "touch", "level dyeing property", "Ease of coating" was evaluated. The viscosities of the mixed liquids in...

Abstract
A two-part hair dye comprising a first preparation containing an alkali agent, a second preparation containing hydrogen peroxide, and a non-aerosol foamer container, wherein the first preparation contains the components (A) to (C) mentioned below, the ratio of the mass of the component (A) to the mass of the component (B) (i.e., an (A) / (B) ratio) in the first preparation is 0.3 or less, and the viscosity of the mixed solution is 1 to 300 mPa·s or more. (A): 0.9 to 1.7 mass% of resorcin. (B): a polyoxyalkylene-type nonionic surfactant. (C): a polymer or copolymer having a molar fraction of a diallyl dimethyl quaternary ammonium salt monomer of 70% or more.
Description
technical field [0001] The present invention relates to a two-component hair dye. Background technique [0002] Conventionally, liquid or cream forms have been widely used as two-component hair decolorizers or hair dyes. But for the unskilled, it is difficult to apply them evenly on the hair. This is because the viscosity of the mixture applied to the hair should be adjusted up to about 1,000-10,000 mPa·s to prevent dripping when left to stand, but this makes it difficult for the agent to spread evenly, and in addition, it is difficult for the agent to fully diffuse to the root of the hair. In addition, when applying to the roots and back of the hair, techniques such as blocking and double-mirror comparison are required, and it takes a lot of time. [0003] In contrast, there is known a method in which a mixed solution of a two-component hair decoloring agent or a two-component hair dye is discharged in a foam form from a non-aerosol foaming container (Patent Document 1). ...
