| 摘要 |
The invention relates to small expanded polymer powder particles, and uses thereof. The expanded powder particles are formed by a non-melt process, resulting in individual expanded particles in the 5 to 100 micron range. The expanded powder particles are especially useful in cosmetic applications, as they provide a softer feel than a powder, and have a much higher surface area, making them highly absorbent for removing liquids and oils, as well as for use as excellent carriers and release agents for active ingredients. |
