Description

  The present invention relates to a hair conditioning composition for a non-gas former, and more particularly, to a hair conditioning composition for use in a non-gas former container that is discharged in the form of a foam without using a propellant (gas). The present invention relates to a hair conditioning composition for a non-gas former that is extremely excellent in foamability, fineness of foam, and sustainability of foam, and has a smooth use feeling and an excellent conditioning effect.

Hair conditioning agent is a hair cosmetic used for the purpose of moisturizing the hair after drying by using it after washing the hair, making it smooth, or improving combing, etc., usually as a conditioning component, Silicones, cationic surfactants, cationic polymers and the like are blended.
In order to maximize the functions of “moisturizing hair”, “smoothing”, and “improves combing”, it is necessary for the hair conditioning agent to spread sufficiently to the hair and to adsorb quickly and evenly. is there. However, since many normal hair conditioning agents have a relatively high viscosity, such as an emulsion to a cream, they do not always have a good spread, and the conditioning component is efficiently applied to each hair tip. It is difficult to adsorb to Therefore, in such a milky to creamy form, it may be difficult to fully extract the function of the conditioning component.

As one means for solving this problem, a method of discharging the hair conditioning composition in the form of foam to increase the gas-liquid interface and efficiently adsorbing the conditioning agent on the hair can be considered.
There are two types of foaming methods: aerosol type that encloses a propellant and non-gas type that does not use a propellant (gas). In addition, it is necessary to consider the smell of the propellant, the corrosion of the container, the increase in the internal pressure of the container due to the increase in room temperature, etc. Also, the non-gas type that does not use the propellant tends to be preferred recently from the viewpoint of cost and environment. . And several methods have already been proposed.

For example, a foam cosmetic composition containing polyoxyethylene polyoxypropylene decyl ether (see, for example, Patent Document 1), or a foam-forming composition containing an appropriate amount of a nonionic surfactant and a polyhydric alcohol (for example, Patent Document 2), hair rinses containing amphoteric surfactants, cationic surfactants and higher alcohols (for example, see Patent Document 3).
JP 2003-277230 A JP 2004-277365 A JP 2006-104149 A

However, when blended with polyoxyethylene polyoxypropylene decyl ether, there is a smooth and supple feeling of use, but it is poor in foaming properties, and fine foam quality cannot be obtained. Difficult to apply. When a nonionic surfactant and a polyhydric alcohol were blended, foaming properties, foam persistence, and smoothness during use were not sufficient. In addition, when an amphoteric surfactant, a cationic surfactant and a higher alcohol are blended, although it has a conditioning effect, it is still not sufficient in terms of foaming properties and foam persistence, and it has a smoothness during use. There wasn't.
Therefore, the foam-like conditioning composition has a high foaming property, the discharged foam is fine, can maintain the foam state, and does not liquefy or sag before applying to the hair. It has been desired to develop a hair conditioning composition for a non-gas former that can apply a conditioning component uniformly with a gentle and smooth feel, and that can provide a sufficient conditioning effect.

  In view of such a situation, the present inventor, in order to solve the above-mentioned problem, pays special attention to preventing the destruction of bubbles, and by making fine bubbles last, the liquefaction and dripping immediately at the time of use. We thought that it was possible to apply evenly to the tip of each hair with a gentle and smooth feel, and as a result, a high conditioning effect was obtained. As a result, a non-cationic polymer, a long-chain acylamino acid salt and / or an alkyl glycol acetate having a specific amount of at least vinylpyrrolidone as a constituent unit in a specific amount of a cationic surfactant or cationic conditioning polymer In combination with a non-gas former container and discharged in the form of foam, it is excellent in foaming properties, fine texture of foam, and prevents destruction and coalescence of the liquid film constituting the foam. The present inventors have found that a hair conditioning composition for non-gas formers that is excellent in sustainability and has a smooth use feeling and an excellent conditioning effect can be obtained, thereby completing the present invention.

That is, the present invention comprises the following components (a) to (d);

As is clear from the results in Table 1, all of the hair conditioners filled in the non-gas former containers of Examples 1 to 10 were compared with those of Comparative Examples 1 to 9, and foamability, fineness of foam, It can be seen that the foam has excellent persistence, excellent feel (smoothness) during use, and excellent conditioning effect. In particular, since it has excellent foam persistence, it can be applied evenly to the tip of the hair with a gentle and smooth feel while the hair is wrapped in soft foam without any dripping in use, and a sufficient conditioning effect is efficient It was a hair conditioner that can be given to.
On the other hand, Comparative Example 1 having a large amount of component (a) is a basic function as a hair conditioning agent because the foam after use, the fineness of foam, and the persistence of foam can be obtained, but the hair after use becomes hard. The conditioning effect was not felt.
In Comparative Example 2 in which the component (b) is not blended, the hair is squeezed at the time of use and there is no conditioning effect after use. In Comparative Example 3 in which the amount of the component (b) is large, the feeling of use is sluggish. The hair became stiff and inferior in conditioning effect.
Comparative Examples 4 and 5 in which other film-forming resins were blended in place of component (c) lacked foaming properties, and accompanying this, neither fineness nor durability of the foams were found. Further, Comparative Example 6 with a small amount of component (c) lacks the sustainability of bubbles that immediately break up, and Comparative Example 7 with a large amount of component (c) has no foaming properties. It was inferior in texture, smoothness during use, and conditioning effect after use.
Further, Comparative Example 8 in which component (d) is not blended lacks foaming properties, so there is no fineness or durability of foam, and Comparative Example 9 in which the amount of component (d) is large is foaming properties and foam texture. Although fineness and foam persistence are excellent and smoothness at the time of use can be obtained, the conditioning component is washed away, so that the conditioning effect after use, which is a basic function as a hair conditioning agent, is lacking.
