What is Carbopol 940 made of?
Carbomer 940 is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent. Carbomer 940 is cross linked with ethers of pentaerythritol, and is used primarily in systems where sparkling clarity or a sharp viscosity response is required.
How do you make chemical gel?
Start with about 5 to 7 g (1 to 1.25 teaspoons) of salt, then add more as needed. Keep adding salt and stirring until the gel turns back to water. Use a glass stirring rod or stick for this.
How do you neutralize Carbopol 940?
Items that can be used to neutralize Carbomer 940 (in ratio): • TEA (Triethanolamine)99%: Begin with 99% pure Triethanolamine, and create a 50% solution with distilled water. Of this solution, you would generally use 4 parts TEA to every 1 part Carbomer 940.
