  • Occlusive agents such as hydrocarbon oils
  • Such high occlusivity is desired as it enhances the penetration into the skin of skin care actives contained in the skin care products.

  • occlusive agents renders skin care products to have a negative skin sensory, e.g., a greasy, sticky feeling, and is thus disliked by users.
  • users prefer skin care products that provide a pleasing skin sensory, like a fresh feel or lower draginess after application.
  • Volatile oils such as low viscosity cyclic silicone oils are commonly used in skin care products to deliver a fresh feel on contact with the skin due to their quick evaporation after being applied onto the skin.
  • volatile oils typically leads to a significant decrease in occlusivity due to a diluted level of occlusive agents and thus a poor penetration of skin care actives.
