Description

Cream-based composition {CREAMY COMPOSITION}

The present invention relates to a creamy phase composition suitable for use as a conditioning agent.

Background Art Conventionally, as a conditioner for setting a hair, a solid, pure feed such as wax has been widely used because of its excellent reverberation and flexibility to hair. However, it is difficult to uniformly apply the solid cleaner to the hair.

With respect to the above problem, an aerosol spray correcting composition which can easily uniformly apply a correcting agent to the entire hair has been developed (see Japanese Patent Application Laid-Open No. 2007-099683). However, it is sometimes difficult to dissolve an oily component of a solid, which is a component for maintaining the repulsive force, in a solvent in a crude solution for cleaning preparation at room temperature. In addition, oily components are precipitated, so that they may not be sprayed sufficiently.

On the other hand, it is also conceivable that the formulation of the correcting agent is made into a cream phase. The cream phase stabilizer is easier to spread on the palm of the hand than the wax-like formulation and is uniformly applied to the hair, and the viscosity of the oily component is small, but the viscosity may change due to the temperature change. This change in viscosity means that the stability of the hand stretch accompanying the temperature change is impaired, and the user may be anxious about quality deterioration.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a cream-like composition which is preferable to be used as a stabilizer by reducing viscosity change with temperature change.

According to an aspect of the present invention,

[A] hydroxy acid ester, [B] cationic surfactant, [C] higher alcohol and [D] water,

Wherein the [A] hydroxy acid ester is an ester of lactic acid and a monohydric alcohol and / or a diester of malic acid and a monohydric alcohol.

The number of carbon atoms of the monohydric alcohol may be 6 or more and 24 or less.

The amount of the [A] hydroxy acid ester in the cream phase composition is preferably 0.5% by mass or more and 5% by mass or less. By setting the content to 0.5% by mass or more, it is particularly suitable for reducing the change in viscosity with temperature change. When the content is 5% by mass or less, the viscosity at room temperature can be prevented from becoming extremely high.

The cream phase composition according to the present invention may be used as a stabilizer. A creamy composition comprising a [B] cationic surfactant, [C] higher alcohol and [D] water is widely used as a stabilizer, and a creamy composition according to the present invention can also be used as a stabilizer. When used as a corrective agent, for example, it is possible to suppress the pressure required for discharging from the pump container or the force required for unfolding with the palm to fluctuate due to the temperature change.

Since the cream phase composition according to the present invention is prepared by mixing the [A] hydroxy acid ester with the [B] cationic surfactant, [C] higher alcohol and [D] water, .

<Viscosity characteristics>

As described above, the creamy phase composition has a small temperature dependence of the viscosity, as compared with the case where the [A] hydroxy acid ester is not blended. This is because, for example, when the closed transparent container containing the creamy composition containing the [A] hydroxy acid ester is allowed to have a fluidity when the composition is tilted after heating [A] without the hydroxy acid ester It can be confirmed from lowering.

The viscosity of the creamy phase composition measured using a B-type viscometer at 25 占 폚 is usually not less than 6,000 mPa 占 퐏 and not more than 40,000 mPa 占 퐏, preferably not less than 7,000 mPa 占 퐏 and not more than 30,000 mPa 占 퐏.

<Precision agent>

As a method of using the creamy composition as a stabilizer, the hair to be treated can be styled by applying the creamy composition to wet or dried hair. The target hair may be hair having a history of perming treatment, coloring treatment, or bleaching treatment, or hair having no hysteresis.

Example

Hereinafter, the present invention will be described in more detail with reference to the creamy phase composition of the examples which can be used as a stabilizer, but the present invention is not limited thereto. The compounding amount of each component in the creamy phase composition is expressed in% in terms of the total amount of the components so that the total amount is 100%. In Table 1, the indication of the% is omitted, and only the numerical value indicating the compounding amount is indicated.

<Evaluation method>

The evaluation methods performed in Examples and Comparative Examples will be described.

(Viscosity change with temperature change)

A closed transparent container (cylindrical container having a diameter of 3 cm) containing the cream-like composition of the example or comparative example was allowed to stand in a thermostatic chamber at 45 캜 or 50 캜 for 3 hours or more. Thereafter, the sealed transparent container taken out from the thermostatic chamber was tilted, and the fluidity of the cream-like composition was visually confirmed. In addition, evaluation was made according to the following evaluation criteria.

Standard: Comparative Example 2

○: There is no liquidity than standard

X: More fluid than standard

&Lt; Examples 1 to 4 and Comparative Examples 1 to 4 >

The cream phase compositions of Examples 1 to 4 and Comparative Examples 1 to 4 were prepared in the compositions shown in Table 1. The creamy compositions of Examples 1 to 4 and Comparative Examples 1 to 4 after preparation had a creamy O / W type emulsion.

Means that the total amount of the ingredients other than the purified water constituting the cream phase composition is added to the total amount of purified water to 100% by mass.

The composition in the form of a cream in Examples had a decrease in viscosity change with temperature change as compared with the comparative example. This is clearly shown in Examples 2 to 4 of Table 1. In other words, the viscosities at 25 占 폚 were lower than those of Comparative Examples 1 to 4 in Examples 2 to 4, but the viscosity changes in Examples 2 to 4 were higher than those of Comparative Examples 1 to 4.

Fig. 1 is a photograph of a sealed transparent container containing the cream-like compositions of Example 1 and Comparative Example 2 left in a thermostatic chamber at 50 캜 for 3 hours or more after being tilted from the left. It can be seen that the slope of the cream phase composition according to Example 1 is steeply curved (low fluidity) compared with that of Comparative Example 2. [ 2 is a photograph of a closed transparent container containing the cream-like compositions of Comparative Example 1, Example 1, Comparative Example 4 and Comparative Example 3 left from the left side in a thermostatic chamber at 45 캜 for 3 hours or more and then tilted to be. It can be seen that the slanting surface of the cream phase composition according to Example 1 has a steep slope (low fluidity) compared with that of the comparative example.
