Abstract

In a hair cosmetic composition having a foamy dosage form using a non-aerosol foamer, it contains an alkali agent, (A) an amino acid-based amphoteric surfactant, and (B) a cationic surfactant. In this case, it is possible to provide a hair cosmetic composition that is capable of forming high-quality foam that does not defoam and that is excellent in applicability and does not sag even at high temperatures.

Description

  The present invention relates to a hair cosmetic composition for use in a foamy dosage form by a non-aerosol foamer. More specifically, the present invention relates to a hair cosmetic composition used as a foam hair dye, foam decolorant or foam decolorizer.

It is known that hair cosmetics such as hair dyes and hair decoloring / decoloring agents are used in the form of foams at the time of use. When these hair cosmetics are used in the form of a foam, they can be uniformly applied to the hair. Furthermore, it is not necessary to increase the viscosity of the hair cosmetic in order to prevent dripping at the time of applying the hair.
In addition, when applying gel-like or cream-like hair cosmetics that are widely used to hair, the hair cosmetics are applied after dividing the hair into a plurality of blocks with clips or the like in order to apply uniformly. . In the foam-form hair cosmetic, the operation of dividing these hairs can be omitted.

  Hair cosmetics used in foamy dosage forms can be classified into aerosol type and non-aerosol type. Aerosol-type hair cosmetics are made into a foamy dosage form by forming bubbles using a propellant such as liquefied gas. In non-aerosol type hair cosmetics, without using a propellant, a non-aerosol former is used to take in air from the outside to form bubbles, thereby forming a foamy dosage form.

The foam-like hair cosmetic formed by a non-aerosol foamer has a problem that it is easy to defoam over time. And the technique that both form a complex and improve foaminess by using a cationic surfactant and an anionic surfactant with respect to this subject is known (patent document 1).
However, foam-like hair cosmetics using a non-aerosol foamer have a problem in that this complex causes ejection failure and high-quality foam cannot be obtained.

  Furthermore, it is known that the ejection failure due to this complex is improved by adding 10% by mass or more of a nonionic surfactant (Patent Document 2).

JP 2011-93820 A JP 2012-31072 A

In addition, a high-quality foam that does not disappear even when left at high temperature is obtained. Furthermore, it is possible to provide a hair cosmetic composition that is excellent in applicability to hair and does not sag even at high temperatures.

Furthermore, the hair cosmetic composition of the present invention may be a two-component type in which a first agent containing an alkaline agent and a second agent containing an oxidizing agent are mixed and used.
Thereby, the hair cosmetic composition which can be easily prepared at the time of use can be provided.

Furthermore, the hair cosmetic composition of the present invention may be used as an oxidative hair dye, a hair decoloring agent, or a hair decoloring agent.
Accordingly, it is possible to provide an oxidative hair dye, a hair decoloring agent, and a hair decoloring agent that are well foamed even at high temperatures, excellent in foam stability, and suppressed from dripping when applied to hair.

[How to use hair cosmetic composition]
The method of using the hair cosmetic composition according to the present invention is a method in which the above-described hair cosmetic composition is made into a foamy dosage form with a non-aerosol foamer and applied to the hair.

  The non-aerosol former is not limited as long as it has a function capable of foaming and discharging non-aerosol type to the hair cosmetic composition. Preferably, foaming can be performed using a non-aerosol former described later.

[Hair cosmetic supplies]
A hair cosmetic product comprises the above-described hair cosmetic composition of the present invention and a non-aerosol foamer for making the hair cosmetic composition into a foamy dosage form.

Typical examples of non-aerosol formers include pump formers and squeeze formers.
The pump former is a device that presses the pump head part to discharge the contained liquid (for example, the first agent / second agent mixed solution of hair cosmetics) in the form of foam. A foam discharger that mixes the stored liquid with air and discharges it in the form of bubbles is attached to the mouth of the container body. A pump former is disclosed in Japanese Patent Application Laid-Open No. 2007-275777 and the like, and is well known.
The squeeze former introduces the liquid and air into the gas-liquid mixing chamber of the foam dispenser by squeezing the soft synthetic resin container body with fingers (repeating compression and decompression operations on the container). And the bubbles formed by the bubble discharger are discharged from the nozzle. The squeeze former is described in Japanese Patent Application Laid-Open No. 2008-291024 and the document “New Trends in Hair Color Technology (Development of Foamed Hair Color Technology)” published in the June 2009 issue of the magazine “Fragrance Journal” It is known.

  The non-aerosol foamer has one or more porous membranes for forming homogeneous bubbles. Examples of the material for the porous membrane include nylon, polyester, polyethylene, and polypropylene. As a mesh of a porous membrane, 50-300 mesh is preferable, for example.

Next, the embodiment will be described more specifically with reference to examples and comparative examples.

Each evaluation of defoaming suppression, foaming, and dripping at high temperatures However, good results were not obtained. On the other hand, in Examples 1 to 4, by containing these components, extremely excellent effects were observed in defoaming suppression, foaming, and dripping at high temperatures.

Further, in Comparative Example 3, a part of the surfactant of Comparative Example 2 was changed to an anionic surfactant (1.1 mass% with respect to the one-agent / two-agent mixture). As a result, although not shown in the table, compared to Comparative Example 2, Comparative Example 3 containing an anionic surfactant was found to have decreased feel and hair dyeability.
In addition, the evaluation method of touch and hair dyeing property evaluated as follows using the oxidation hair dye of the comparative examples 2 and 3 for the hair. The foamed oxidative hair dyes of Comparative Examples 2 and 3 were applied to the hair, allowed to stand for 30 minutes, and then washed well. After the hair was thoroughly dried, the hair dyeing states of the hairs using Comparative Examples 2 and 3 were compared by visual observation. In addition, the feel of hair using Comparative Examples 2 and 3 was evaluated by comparing the fingering of the hair after washing and after drying.
