Definitions

  • This specification describes a cosmetic composition for controlling sebum.
  • Sebum is a secretion from the sebaceous glands of the skin and is composed of cholesterol, fatty acids, and ester compounds. Sebum works to prevent dryness on the surface of the skin, but it can cause grease or makeup stains on the face. Therefore, in the case of sunscreens or makeup compositions, products that can control the amount of skin sebum have been studied in order to maintain a smooth and smooth application throughout the day. In order to control the amount of skin sebum, non-porous powder or porous spherical powder is mainly used.
  • Non-porous spherical powder has poor oil absorption, and porous powder particles have a high penetrating volume, so sebum absorption is excellent, but the surface area is too high, so the possibility of elution of stabilized components in the particle matrix is high, and mechanical properties are not Compared to the porous particles, there is a problem that the particles may be broken in the mixing process (homomixing, high pressure emulsifier, etc.).
