METHOD FOR THE DISPERSION OF WATER-SOLUBLE OR HYDROPHILIC SUBSTANCES IN A SUPERCRITICALLY PRESSURIZED FLUID |
| 摘要 |
<p>Process for dispersing water-soluble or hydrophilic substances (I) in a fluid (II) at supercritical pressure by adding a surfactant (III) that is a block copolymer comprising a CO-2-philic block (B1) and a nonionic hydrophilic block (B2). Independent claims are also included for the following: (1) method for encapsulating an active agent that includes the new dispersion process; and (2) block copolymer that comprises B1 and a biocompatible B2.</p> |
