摘要:
The invention relates to a method for the production of biosourced aliphatic polyester powder having a volume median diameter of less than 30 μm, comprising: a step consisting in supplying an aliphatic polyester having an inherent viscosity of less than 0.5 dl/g; and a step consisting in grinding the polyester, so as to obtain a polyester powder having a volume median diameter of less than 30 μm. The invention also relates to a powder in which the particles have a volume median diameter of less than 30 μm and are impregnated with a compound selected from among polyols and/or carboxylic acids. The invention further relates to the use of the powder for the production of cosmetic, pharmaceutical and perfume products.
摘要(中):
本发明涉及一种生产体积中值粒径小于30μm的生物质脂族聚酯粉末的方法,包括:提供特性粘度小于0.5dl / g的脂族聚酯的步骤; 以及包括研磨聚酯的步骤,以获得体积中值粒径小于30μm的聚酯粉末。 本发明还涉及其中颗粒的体积中值直径小于30μm并用选自多元醇和/或羧酸的化合物浸渍的粉末。 本发明还涉及粉末用于生产化妆品,药物和香料产品的用途。
