Abstract:
본 발명은 화산송이 분말과 다공성 고분자의 복합분체에 관한 것으로, 보다 상세하게는 고분자를 용해시킨 용액에 화산송이 분말을 분산시킨 분산액을 단일공정(One-step)으로 분무하여 제조되는 화산송이 분말 입자가 다공성 고분자의 표면 및 내부에 고르게 함침(Impregnation)된 복합분체(Scoria sphere), 이를 함유하는 화장료 조성물 및 이의 제조방법에 관한 것이다. 본 발명의 화산송이 분말 입자를 다공성 고분자에 고르게 함침시킨 화산송이 함침 분체를 화장료 조성물로서 제형화시키면, 마이크로 사이즈로 미세화된 화산송이의 피지 흡유 성능을 다공성 고분자가 보완하여 피지 흡착력이 크게 향상된다.
Abstract:
The present invention relates to an inorganic powder coated with a biocompatible polymer and a cosmetic composition containing the same, and more specifically, to an inorganic-organic hybrid powder having improved dispersibility and tactile sensation by treating a rough surface of an inorganic powder with a biocompatible polymer, and to a cosmetic composition having improved tactile sensation and adhesiveness when applied to the skin by containing the hybrid powder.
Abstract:
PURPOSE: Organic and inorganic composite powder for blocking UV rays and a cosmetic composition containing the same are provided to ensure excellent UV protection ability, dispersion property, softness, and a moisturizing effect. CONSTITUTION: Organic and/or inorganic composite powder for blocking UV rays is prepared by surface-treating inorganic powder with one or more phospholipids selected from 2-methacryloyloxyethyl phosphorylcholine and 2-methacryloyloxyethyl phosphatidylcholine. The inorganic powder is selected among titanium oxide and zinc oxide. The inorganic powder contains 0.1-8% of phospholipid. A cosmetic composition for blocking UV rays contains 0.1-25wt% of organic and inorganic composite powder.

Abstract:
PURPOSE: A cosmetic composition containing nanoparticles is provided to ensure colloid stability and to enable safe biodegradation in vivo. CONSTITUTION: A nanopaticle is prepared by impregnating physiologically active ingredients into amphiphilic polymers of a sterostructure comprising a core part with a plurality of branches formed of hydrophobic polymers and an arm part formed of hydrophilic polymers. The hydrophobic polymers are is a copolymer formed of poly-carprolactone, poly-L-lactic acid, poly-D,L-lactic acid, poly-D-lactic acid-co-glycolic acid, poly-L-lactic acid-co-glycolic acid, poly-D,L-lactic acid-co-glycolic acid, or monomer thereof. A cosmetic composition contains the nanoparticles as an active ingredient.
