Carbomer 940 VS 941: What should you know?
If you are in the business of distributing products such as lotions, gels, creams and disinfectants, you have probably heard of Carbomer 940 and Carbomer 941. But because the two are relatively similar, you may be confused by the differences between the two. Although they have similarities, they are quite different and have different effects on the product. Check the information below to learn more about the comparison between Carbomer 940 and Carbomer 941.
What is carbomer?
Carbomer is an important material that every formulator should be familiar with. They are acrylic cross-linked polymers with high molecular weights up to 4 billion daltons. If there is no crosslinking, the polymer will be a series of linear polymer chains that are physically connected to each other but not chemically bonded. Carbomer is polymerized into ethyl acetate, cyclohexane, pentaerythritol polyallyl ether and polyallyl sucrose are widely used crosslinking agents. ,
What is Carbomer 940
Carbomer940, used to increase viscosity. It is also a gelling agent or suspending agent, a polyvinyl carboxyl polymer. Carbomer 940 is cross-linked with pentaerythritol ether and is mainly used in systems that require shiny transparency or sharp viscosity response. When applied to formulations, it has excellent softness and slip properties comparable to ethylene glycol.
Carbomer 940 powder can also be used to thicken surfactant systems and make suspension products. It is excellent when you need to suspend heavy particles. In fact, viscosity has little to do with the ability to suspend objects. A gel with the same consistency as jelly will cause the suspended particles to rise or fall. This is because Carbomer forms a network that can easily suspend these particles.
What is Carbomer 941?
The polymer Carbomer 941 is a white powder polymer cross-linked with polyacrylic acid. It is designed to suspend, stabilize and improve the appearance of low-viscosity personal care products. It provides excellent low viscosity emulsion and suspension stability. It is recommended for a range of personal care applications, including clear gels, hydroalcoholic gels and lotions. Here are some of its advantages:
1. Excellent freeze-thaw and high temperature stability in low-concentration oil-in-water emulsions
2. The gel made with this polymer has excellent transparency.
3. Long rheology, high yield value
4. Medium plasma tolerance and poor shear tolerance
Carbomer 940 and 941
Now that you know the difference between the two carbomers, it is easier to understand why carbomer 940 and carbomer 941 are often confused. Both have their own characteristics and affect the parameters of the product in various ways. Desheng is a professional manufacturer of Carbomer 940.
