Carbomer gel in Polyethylene glycol
Hello everyone!
I am working on a non-aqueous PEG 400-based carbomer gel, and struggling with how to make it quickly. I’m using Carbopol 974P and it swells very slowly in PEG-400.
Here is what I did:
- Dispersed Carbopol 974P in PEG-400 using a homogenizer speed 7000 rpm x 10 minutes.
- Heat the mixture to 70 degrees celsius and kept it there for nearly one hour.
- Then I left the mixture overnight at room temperature.
The next morning it hadn’t completely swollen and formed a gel.
If you guys have any recommendations, please let me know.
Thank you so much!
