Thickeners - High Polarity Formulations
I would love to hear suggestions or opinions regarding the selection of thickeners in formulations with highly polar actives (typically anywhere from 1-5%). More specifically, I am looking for a thickener that has the following characteristics:
- Functions at pH 3-7 (roughly)
- Compatible with skin
- Can handle highly polar actives
- Med-High electrolyte tolerance (optional)
- Nice feel (optional - also ideal)
In addition to a single thickener, I am also open to options regarding the use of multiple thickening agents to accomplish the same task. These could include starches, gums, polyacrylates, ect.
Any suggestions would of course be highly appreciated. I look forward to your comments and advice.
