Problems solved by technology

However, although such amphiphilic anisotropic powders show high applicability, methods for the large-scale production of amphiphilic anisotropic powders have not been developed so far
Moreover, it is difficult to uniformly produce amphiphilic anisotropic powders in large quantities on an industrial scale, which leads to impractical application

[0140] The ingredients used in Preparation Examples 1 to 4 are shown below.

[0141] [Table 1]

[0142]

[0143] MeOH: methanol (co-solvent)

[0144] KPS: potassium persulfate (initiator)

[0145] SVBS: sodium vinylbenzene sulfonate (stabilizer)

[0146] PS: polystyrene (polymer beads)

[0147] CS: Coated first polymer spheres with core-shell structure

[0148] DB: Amphiphilic anisotropic powder

[0149] TMSPA: Trimethoxysilylpropyl acrylate (functional group)

[0150] AIBN: azobisisobutyronitrile (polymerization initiator)

preparation example 1

[0151] Preparation Example 1. Preparation of Polystyrene (PS) First Polymer Spheroids

[0152] First, 50 g of styrene as a monomer, 1.0 g of sodium 4-vinylbenzenesulfonate as a stabilizer, and 0.5 g of azobisisobutyronitrile (AIBN) as a polymerization initiator were mixed in an aqueous phase, and It was allowed to react at 75°C for 8 hours. The reaction was carried out by stirring the reaction mixture at a speed of 200 rpm in a cylindrical reactor having a diameter of 11 cm and a height of 17 cm and made of glass.

preparation example 2

[0153] Preparation Example 2. Preparation of Coated First Polymer Spheroids with Core-Shell (CS) Structure

[0154] First, 300 g of polystyrene (PS) first polymer spherical particles obtained as described above were mixed with 50 g of styrene as a monomer, 6 g of 3-(trimethoxysilyl)propyl acrylate (TMSPA) and 0.2 g Azobisisobutyronitrile (AIBN) as a polymerization initiator was mixed, and the reaction mixture was reacted at 75° C. for 8 hours. The reaction is carried out by stirring the reaction mixture in a cylindrical reactor.

Abstract

The present specification relates to an oil-in-water type emulsion cosmetic composition containing an amphiphilic anisotropic powder and ceramide, wherein the amphiphilic anisotropic powder contains afirst polymer spheroid which is hydrophilic and a second polymer spheroid which is hydrophobic, wherein the first polymer spheroid and the second polymer spheroid bind by at least partially penetrating the other polymer spheroid, wherein the first polymer spheroid has a core-shell structure, wherein the shell contains a functional group, and wherein the ceramide contains oil phase ceramide included in oil phase and ceramide particles included in water phase.

Description

technical field [0001] The present disclosure relates to an emulsion-type cosmetic composition comprising ceramide and a method for preparing the same. Background technique [0002] Intercellular lipids give the skin its physicochemical barrier function. The intercellular lipid mainly includes ceramide, fatty acid, cholesterol, cholesteryl ester, etc., and the proportion of ceramide reaches about 40 to 60%. Ceramides play a very important role in forming lipid structures and providing barrier function. Ceramides have the characteristic that they are difficult to handle in cosmetic formulations due to the van der Waals attraction between the nonpolar tails and the intermolecular hydrogen bonding that occurs in the amino-carbonyl and hydroxyl groups of the polar headgroup . Pseudoceramides also have unique thermal behavior due to their geometry and hydrogen bonding of the head group, and thus pose difficulties in designing formulations and controlling the manufacturing proc...
