Biocompatible nanoparticles containing block copolymers and production thereof

All Rights Reserved. Biocompatible nanoparticles containing block copolymers and production thereof. Tsujimoto, Hiroyuki; Hara, Kaori (Hosokawa Powder Engineering Research Institute, Japan). Jpn. Kokai Tokkyo Koho JP 2006321763 A 30 Nov 2006, 24pp. (Japanese). (Japan). CODEN: JKXXAF. APPLICATION: JP 2005-147664 20 May 2005. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) The invention relates to biocompatible nanoparticles consisting of a block copolymer having a core-shell structure with biocompatible hydrophobic polymer block (core) and a biocompatible hydrophilic polymer block (shell), wherein a hydrophilic active component is encapsulated in the hydrophilic block. The hydrophobic and hydrophilic core-shell structure can be opposite order, and a hydrophobic active component can be encapsulated in the hydrophobic block. The nanoparticle shows higher encapsulation rate regardless of the hydrophilicity of the active component. 108910-78-7 and 183476-82-6 are also in the experiment. A method for prodn. of the nanoparticles is also disclosed. For example, a block copolymer of polyethylene glycol and lactic acid-glycolic acid copolymer 4 g was dissolved in acetone 80 mL, mixed with caffeine 1g/water 5 mL, and dropped in polyvinyl alc. soln. to obtain a caffeine-encapsulated nanoparticles. .

Composition for accelerating collagen synthesis

CODEN: CPXXEB. APPLICATION: CA 2005-2508094 20 May 2005. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 63 The present invention has as an object to provide a collagen synthesis accelerator. By employing at least one compd. selected from the group consisting of ascorbic acid, ascorbic acid derivs. and salts thereof together with a low mol. wt.In this article, certain chemicals are used. Some of their cas registry numbers are 183476-82-6 and 82486-89-3 betaine, the effect on accelerating collagen synthesis is enhanced, whereby the amt. of collagen synthesis is significantly increased. Therefore, an excellent compn. for accelerating collagen synthesis or collagen synthesis accelerator can be provided. Thus, a sunscreen compn. contained ascorbyl tetra-2-hexyldecanoate 0.1, trimethylglycine 1.0, 2-ethylhexyl-p-methoxycinnamate 10.0, decamethyl cyclopentasiloxane 20.0, octyl palmitate 10.0, polyoxyethylene/methylpolysiloxane copolymer 3.0, zinc oxide treated with Me hydrogen polysiloxane 15.0, alkyl polyacrylate 5.0, glycerol 5.0, ethanol 5.0, 1,3-butylene glycol 3.0, panthenol 0.1, perfume 0.1, phytic acid 0.05, and water to 100%, resp. .
