| abstract |
The present invention relates to the field of gel-based delivery systems for compounds of interest such as drugs or cosmetic agents. Providing a gel comprising at least one non-polymeric gelling agent and at least one polymer, the polymer content of the gel is greater than 5 weight percent (wt%), preferably at least greater than 10 wt% More preferably at least 20 wt%. Further provided are methods for preparing the gel and use of the gel in a controlled delivery system (eg, a pH sensitive drug delivery system). |
