  • Preparation Example 4 was found to be very excellent in moldability similar to Comparative Preparation Example 1 using the talc without using talc.
  • Comparative Production Examples 1-3 and 5 containing no acrylic polymer showed very poor moldability.
  • the comparative evaluation was made by using the cosmetics of Preparation Examples 1-4 and Comparative Preparation Examples 1-5 for 20 women in their 20s to 30s through a consumer panel test, specifically, the shrinkage rate is about 15 hours at about 50 °C
  • the degree of shrinkage in the molding plate when dried, the blowing out of the powder when brushing 10 times with a brush, the degree of cracking stability when the drop was dropped above 20 cm, the degree of cracking of the raw material functionality, and transparent pores were evaluated.
  • the larger the shrinkage rate and powder blowing 5 points out of 1 to 5 points, cracking stability, the higher the raw material functionality was evaluated to 5 points out of 1 to 5 points.
  • Table 5 The results are shown in Table 5 below as an average value.
  • Preparation Examples 1, 2 and 4 except for Preparation Example 3 containing a very small amount of the acrylic polymer in the production examples of the present invention shows a very low shrinkage and powder blowing, high cracking stability and raw material functionality It can be seen that it will show excellent stability even in the preparation of the fact.
  • Preparation Example 4 like Comparative Preparation Example 1 using talc, had excellent cracking stability, but because Talc was not used, Comparative Preparation Example 1 had very low functionality of raw materials, that is, the pore cover function of the powder was reduced. The cover function was also very good.
  • Comparative Preparation Examples 2-4 which do not contain an acrylic polymer, were all severe in shrinkage rate and dusting, and were also cracked, and thus, they could not be manufactured in fact.

Abstract

La présente invention porte sur une composition cosmétique comprenant un polymère à base acrylique, permettant d'y combiner de façon stable un constituant en poudre et ainsi d'obtenir une excellente aptitude au moulage. Plus précisément, la composition cosmétique selon la présente invention permet d'inclure de façon stable une grande quantité d'un constituant en poudre tel qu'une poudre sphérique et, de plus, elle permet d'obtenir une excellente aptitude au moulage puisque la forme sphérique peut être conservée en raison de l'excellente élasticité que le polymère à base acrylique possède même si une pression est appliquée pendant la transformation de la composition cosmétique en une forme compacte.
