  • Patent number: 11229586
    Abstract: A surfactant-free cosmetic composition is disclosed. The composition is a stable water in silicone oil (W/S) formulation containing a silicone oil phase portion and an aqueous phase portion, wherein the silicone oil phase portion contains an emollient having a pyrrolidone carboxylic acid group, oil-absorbing powder and silicone oil, and the aqueous phase portion contains 50 wt.% or more of water based on the total weight of the surfactant-free cosmetic composition. The composition may further contain a high content of vitamin C or a vitamin C derivative and has improved long term storage stability.

  • Publication number: 20200397671
    Abstract: The present invention relates to a cosmetic composition of a multiple emulsion formulation having a lamellar liquid crystal structure, and a method for preparing the same. More particularly, the cosmetic composition is prepared using different single emulsification type emulsions, i.e. a W/O type emulsion and an O/W type emulsion which has a lamellar liquid crystal structure, or using a mixture having constituent ingredients thereof. Thus, the present invention has effects of stably maintaining effective ingredients of the cosmetic composition, and enhancing the feeling of use.

  • Publication number: 20080268004
    Abstract: The present invention relates to a water-in-oil-in-water multiple emulsion system and a method for preparation thereof, characterized by hydrodynamically stabilizing the multiple emulsion system by using hydrodynamic dual stabilization (HDS) technology. The HDS technology hydrophobizes water molecules in the internal aqueous phase by using a hydrogen bonding inhibitor and by improving the aggregating force between water molecules in the internal aqueous phase by using a water molecule aggregating agent.
