Description

{POWDER SKIN CLEANSER}

The present invention relates to a powdery or granular skin cleansing agent.

Conventionally, the powdery skin cleansing material is prepared by mixing and grinding an inorganic powder or an organic powder to be a cleaning agent with a builder. In the case of using a granular skin cleansing agent, (Granulation). Since the powdery or granular skin cleanser is free of moisture as compared with the liquid or gel phase, it is possible to provide a product with higher safety without blending a preservative or a bactericide. However, the powdery or granular skin cleanser is not uniformly dissolved when it is dissolved in water by a palm, a sponge, or the like, and there are disadvantages that are called " pellets " or " lumps ". Further, the foamability (foaming property) is also inferior to that of the liquid phase or the gel phase. In particular, N-acylglutamate is weakly acidic and has little irritation to the skin. Therefore, it is often used as a highly safe cleansing ingredient, but it is not easily dissolved in water and has a drawback that the foamability deteriorates when it is used as a powder washing detergent. The applicant of the present invention has found that when the cationic dextran is formulated in the formulation, the safety is improved, the solubility at the time of use is improved, the foam property is excellent, and even when the foam is caused by the palm of the hand, (Patent Document 1: Japanese Patent Application Laid-Open No. 2002-338994). In addition, Japanese Patent Application Laid-Open No. 2009-196971 proposes a detergent composition having excellent foaming properties by combining N-acylglutamate or higher fatty acid salt, polyamino acid and neutral amino acid. However, an additional performance improvement is required.

[Example]

Each of the ingredients shown in Table 1 was compounded in N- (coconut oil fatty acid / palm oil fatty acid / sunflower oil preservative acid) sodium acylglutamate at a concentration of 0.5, 1, 3 and 5% by mass, 12 were prepared. The foam quality and foaming property of the prepared powdery skin cleansing materials were evaluated by the following criteria.

Evaluation of the quality of foam

To 10 professional panelists, take 0.6 g of the prepared sample into the palm of your hand, add about 2 to 3 mL of tap water, rub your hands for about 30 seconds, then let the air bubble into the bubble, .

(Coconut oil fatty acid / palm oil fatty acid / sunflower oil preservative dispersion) The foam quality of the powdery skin cleansing agent solely sodium sodium acyl glutamate was used as a standard and evaluated according to the following criteria.

4 points: Remarkably resilient, fine texture.

3 points: There is elasticity, texture is fine.

2 points: It does not change.

1 point: Less resilience, rough texture.

0 point: Significantly less elasticity, rough texture.

The average values of 10 evaluation points are shown in Table 1.

Bubble castle  A rating

10 panelists were asked to evaluate the quality of foam and the foaming properties at the same time.

(Palm oil fatty acid / palm oil fatty acid / sunflower oil retention spread) The foaming property of the powdery skin cleansing agent alone of sodium acyl glutamate was evaluated as a standard according to the following criteria.

4 points: The bubbles rise remarkably quickly.

3 points: The bubble bursts quickly.

2 points: It does not change.

1 point: The bubbles rise late.

Score 0: Significant bubbles rise late.

The average values of 10 evaluation points are shown in Table 1.

Comprehensive evaluation

The average value of the evaluation of the quality of the foam and the average value of the evaluation of the foaming property were added together and evaluated according to the following criteria.

◎: 6 points or more and 8 points or less
