  • a 0.7 g cluster was placed in a cylindrical cell with a diameter of 13 mm, compressed to make a tablet with a thickness of 5 mm, the tablet was separated from the cell to manufacture a primary tablet, and this was heat-treated in an oven at about 80° C. for 2 hours to manufacture a solid cosmetic.
  • the porosity below 200 ⁇ m (Ss/St) and the porosity above 200 ⁇ m (Sb/St) were calculated based on 200 ⁇ m, and the porosity ratio (Ss/Sb) was calculated.
  • Ta Measurement of water penetration time: Place a tablet in the center of a cylindrical container with an inner diameter of 28 mm and a height of 13 mm, and place a 100 g weight on the tablet. Add 2 ml of water to the cylindrical container so that the weight and tablet do not come into direct contact with the water, and measure the time it takes for the weight to move.
  • Tablet dissolution evaluation The tablet was placed in contact with 5 ml of water for 30 seconds and rubbed with both hands to check whether the tablet was completely dissolved within 30 seconds.
  • Comparative Example 1 is a case where the size of the solid particles is 50 ⁇ m or less and the solid particles do not form clusters
  • Comparative Example 2 is a case where the size of the solid particles is 74 ⁇ m or less and the solid particles do not form clusters
  • Comparative Example 3 is a case where the size of the solid particles is 1000 ⁇ m or less and the solid particles form clusters of 4000 ⁇ m or less.
  • Example 1 is when the size of the solid particles is 50 ⁇ m or less and the solid particles form clusters of 150 ⁇ m or less
  • Example 2 is when the size of the solid particles is 74 ⁇ m or less and the solid particles form clusters of 300 ⁇ m or less
  • Example 3 is when the size of the solid particles is 74 ⁇ m or less and the solid particles form clusters of 1000 ⁇ m or less
  • Example 4 is when the size of the solid particles is 300 ⁇ m or less and the solid particles form clusters of 2000 ⁇ m or less
  • Example 5 is when the size of the solid particles is 500 ⁇ m or less and the solid particles form clusters of 2000 ⁇ m or less
  • Example 6 is when the size of the solid particles is 850 ⁇ m or less and the solid particles form clusters of 3000 ⁇ m or less.
  • the number of solid particles and the number of clusters included in the solid cosmetic decrease.
  • the porosity ratio (Ss/Sb) is preferably ⁇ 2. If (Ss/Sb) > 2, it is judged that the non-exhausted air is generated during the process of absorbing water into the solid cosmetic by capillary action, which partially interrupts the function process or causes the bubbles to escape slowly and be absorbed, which is the factor that causes Ta to exceed 30 seconds.
  • FIG. 5 is a micrograph showing a solid cosmetic surface according to an embodiment of the present invention.
  • the present invention relates to a solid cosmetic and has industrial applicability.

Abstract

La présente invention concerne des particules solides comprenant un composant liquide, des particules en grappe et un produit cosmétique solide les comprenant, et leur procédé de fabrication. Un produit cosmétique solide selon un mode de réalisation de la présente invention comprend : la canalisation de pores pour alimenter rapidement et uniformément l'intérieur avec de l'eau, une solution aqueuse, ou un liquide hydrophile depuis l'extérieur; une pluralité d'agrégats formés de particules solides contenant un principe actif liquide ayant une solubilité dans l'eau; et un principe actif adhésif pour faire adhérer ou lier la pluralité d'agrégats les uns aux autres, les pores de canalisation étant formés par l'adhérence ou la liaison entre la pluralité d'agrégats.
