Do you know that these differences between Carbomer 940 and 941 are still difficult to choose?

Descripción del producto

If you are familiar with products such as lotions, gels, creams and disinfectants, you may have heard of Carbomer **0 and Carbomer **1. However, due to the high similarity between the two, you may be confused about the differences between each other.
 
Although they have similarities, they are very different and have different effects on the product. Check out the information below to learn more about the comparison between Carbomer **0 and Carbomer **1.

What is carbomer?
Carbomer is an important material, and every formulator should be familiar with it. They are high molecular weight acrylic cross-linked polymers with a molecular weight of up to 4 billion daltons. Without crosslinking, the polymer will be a series of linear polymer chains that are physically connected to each other but not chemically bonded. Carbomer polymerization into ethyl acetate, cyclohexane, pentaerythritol polyallyl ether and polyallyl sucrose are widely used crosslinking agents.
 
What is Carbomer **0?
Carbomer **0 is used to increase viscosity. It is also a gelling agent or suspending agent, a polyvinyl carboxyl polymer. Carbomer **0 is cross-linked with pentaerythritol ether and is mainly used in systems that require foaming transparency or sharp viscosity response. Carbomer **0 powder can also be used to thicken surfactant systems and make suspension products. It is excellent when you need to suspend heavy particles. When applied to formulations, it has excellent softness and slip properties compared to ethylene glycol.
 
advantage:
1. Stable oil-in-water emulsification system, suitable for emulsions and creams
2. (Jelly type) Very short rheology
3. The produced gel has excellent transparency and high viscosity.
4. Low ion resistance, low shear resistance, high yield value (suspension ability)
 
What is Carbomer **1?
The polymer Carbomer **1 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 has excellent low viscosity emulsion and suspension stability. It is recommended for various applications in personal care, including clear gels, hydroalcoholic gels and lotions.
 
advantage:
1. Low-concentration oil-in-water emulsion has excellent freeze-thaw and high temperature stability
2. The gel made of this polymer has excellent transparency.
3. Long stream quality
4. Relative viscosity difference and yield value increase
5. Medium tolerance to ions, poor tolerance to shear
 
It is not difficult to understand why Carbomer **0 and Carbomer **1 are often confused. However, both have personalities that affect the product in various ways. As long as you understand the difference between them, it will be helpful for you to use or purchase.
