粉末化粧料の光学·機械的·薬剤放出特性向上

摘要

中部地域の産官連携により，合成シーズと評価シーズ，化粧品ニーズの融合と，独自製品·感性研究の速成に成功した。液中平均表面間距離と表面凝縮·体積凝縮の制御により，複合粒子·中空体·薬剤内包顆粒を作製し，UV遮蔽性向上や，光学的メリハリの改善，薬剤徐放速度制御ができた。一面せん断試験と官能評価の系統的検証により，定性的な官能指標と物理的特性との関連付けと，評価法の標準化を促進した。%Through collaboration between industry and government in the Chubu region, we succeeded in blending synthetic seeds, evaluation seeds, cosmetics needs and quickly establishing original products and sensibility studies. By controlling the average intersurface distance in the liquid and the surface/volume precipitation in the droplet, it was possible to prepare the composite particle, hollow granule and drug-encapsulating granule. These microstructure controls enabled us to improve the UV shielding property, improve the optical sharpness, and obtain a controlled release rate of the drug. Systematic verification of direct shear testing method and organoleptic evaluation promoted the association between qualitative sensory parameters and physical properties; furthermore, enabling the standardization of the evaluation method.
