  • Comparative Example 1 in which the component (a) of the present invention is not blended is not stable because the emulsified state is poor, and Comparative Example 3 in which the amount of the component (b) is large has a feeling of water break.
  • Comparative Example 4 in which the amount of component (c) is small satisfactory characteristics cannot be obtained.
  • Comparative Example 5 in which the component (e) is replaced with high-viscosity silicone is not preferable in stability, and Comparative Examples 6 and 7 in which the IOB value is replaced with an oil outside the range of 0.1 to 0.4 are used for stability and use It is not preferable in terms of feeling.
  • the trace amount (b) component has contributed to stability improvement from the comparative example 2.

Abstract

L'invention concerne un matériau cosmétique libérant de l'eau qui présente une excellente stabilité même lorsqu'un absorbant d'ultraviolets est fortement mélangé, dont l'état émulsionné est rompu en douceur lors de l'application, ce qui permet d'obtenir un bon étalement, et qui offre une excellente sensation d'utilisation. Le matériau cosmétique libérant de l'eau comprend une émulsion de type eau dans huile contenant : (a) 0,1 à 4 % en masse d'au moins un composé choisi parmi une silicone à modification polyéther partiellement réticulée et une silicone à modification polyglycérol partiellement réticulée; (b) 0,05 à 1,5 % en masse d'un agent actif de silicone non réticulé; (c) 30 % en masse ou plus d'un composant aqueux; (d) 3,5 à 20 % en masse d'un absorbant d'ultraviolets; et (e) 3 à 45 % en masse d'au moins un élément choisi parmi une huile de silicone ayant une viscosité de 1 à 20 mm2/s à 25 °C et une huile d'ester ayant une valeur d'IOB (balance inorganique/ organique) de 0,1 à 0,4.
