I'm curious about any suggestions you may have on the best methods for extracting fragrance from various cosmetic bases (shampoos, lotions, condtioners, etc.). Currently, I am using a pentane extraction method and a simple distillation method. My GC runs are hit-and-miss. So, I'm wondering if there is something else I should be doing. Any suggestions would be greatly appreciated.
1. Try Hexane instead of Pentane, extract and run through GC.
2. Try DMSO (Dimethyl sulfoxide), extract and run through GC.
3. Check EPA methods.
Note: It may be necessary to acidify the solution prior to extraction.
