Description

  The present invention relates to oily cosmetics such as makeup cosmetics, eyelash or eyebrow cosmetics, oil-in-water base cosmetics, and sunscreen cosmetics.

  Oily cosmetics such as lipstick, lip balm, lip gloss, blusher, foundation, foundation cosmetic, mascara, eyebrow have good adhesion to the skin, eyelashes or eyebrows for the purpose of improving makeup. Solid oils such as beeswax, carnauba wax, candelilla wax and paraffin wax, which can impart water resistance and sebum resistance by application to the skin, eyelashes or eyebrows, are blended. However, when the blending amount of the solid oil agent is too large, the coating film becomes cloudy and has a matte texture, resulting in a problem that glossiness cannot be obtained and spreadability is deteriorated.

  In addition, sunscreen cosmetics that protect the skin from ultraviolet rays generally contain an ultraviolet protective agent such as an ultraviolet absorber or an ultraviolet scattering agent and a liquid oil agent (see Patent Documents 1 to 3). These UV protection agents are prone to agglomerate, and if an amount for obtaining a sufficient UV protection effect is blended, there is a problem that when the UV protection agent agglomerates and is applied, white floating occurs or spreadability deteriorates. It was. Moreover, after application | coating, there also existed a problem that the squeak and the skin became thick with progress of time.
