What is Carbomer 940?
Carbomer 940 is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent.
What is Carbomer 940 used for?
Carbomer 940 is used primarily in systems where clarity or viscosity is required, such as in gel-creams, hair gels, lotions, and creams.
What is the typical use level of Carbomer 940?
The typical use level of Carbomer 940 is 0.1-0.5%, depending on the desired viscosity of the formulation.
How is Carbomer 940 neutralized?
Carbomer 940 can be neutralized with inorganic bases such as NaOH or KOH, triethanolamine (TEA), Tetrasodium EDTA, or Suttocide A.
What is the pH range required to achieve gel structure with Carbomer 940?
The pH needs to be raised to >6.0 to achieve a gel structure with Carbomer 940.
What are the benefits of Carbomer 940?
Carbomer 940 acts as a powerful, pH-sensitive gelling thickener that is useful for making clear gels and stabilizing emulsions.
How does Carbomer 940 compare to standard surfactant thickeners in terms of fragrance and essential oil incorporation?
Carbomer 940 has better viscosity and can withstand the incorporation of different fragrance and essential oils compared to standard surfactant thickeners.
Can Carbomer 940 suspend heavy particles?
Yes, Carbomer 940 is excellent at suspending heavy particles and can create a network that effectively traps and suspends beads.
What is the recommended neutralizing agent for Carbomer 940?
Tetrasodium EDTA or Suttocide A are recommended as neutralizing agents for Carbomer 940.
How should Carbomer 940 be added to formulations?
Carbomer 940 should be added to room temperature liquid only.
