Product Description

Carbomer resin is a high molecular polymer with a certain degree of cross-linking and network structure. It is a special functional material with strong water absorption capacity and has been widely used in the pharmaceutical industry, daily chemical industry and other related industrial fields. However, Carbomer 940 generally has the problem of strong absorption of pure water and insufficient salt water resistance, which limits the application of carbomer resin in the field of daily cosmetics. When the water contains salt, its viscosity drops to the original 2 after absorbing water. %-10%, limiting its application promotion. To solve the problem fundamentally, we first need to understand what can affect the salt tolerance of Carbomer?
 
1. The effect of monomer ratio on the viscosity and salt resistance of carbomer resin
When the salt-tolerant non-ionic group of SMA increases, the resin is less affected by salt, and the viscosity retention rate of the finished carbomer product μ (the larger the μ indicates the stronger the salt-tolerant ability of the thickener) increases, when the amount of SAM increases Although the salt tolerance of carbomer has been improved, it does not swell in water, so the amount of SMA is not easy to be too large, and it is generally controlled below 5% according to needs.
 
2. The effect of polymerization temperature on the salt tolerance of carbomer
When the reaction temperature increases, the viscosity of the synthesized product decreases. The main reason is that when the temperature increases, the free radicals generated during the reaction increase, resulting in the smaller the molecular weight of the polymerization, the lower the viscosity of the carbomer, but the resistance to salt Less affected.
 
3. The influence of the amount of initiator on the salt tolerance of carbomer
When the amount of initiator is increased, the free radicals generated during the polymerization process increase, resulting in a decrease in the relative molecular weight of the polymerization. The lower the viscosity of the carbomer, the less impact on the salt resistance.
 
4. The influence of the amount of crosslinking agent on the salt tolerance of carbomer
When the crosslinking agent used in the synthesis of salt-resistant carbomer resin is below 1.0%, the more the amount of crosslinking agent is, the viscosity retention rate μ will increase accordingly. When the crosslinking agent increases, the resin will form a tighter shrinkage cross Connected grid, water absorption and salt tolerance are reduced.
 
Summary:
The change of initiator and temperature has little effect on the viscosity retention rate μ, that is, salt resistance; when the monomer concentration increases, the viscosity retention rate IV of the finished carbomer will increase, but when the SMA/AA exceeds 5% , Carbomer resin does not swell in water, so it is better to choose monomer ratio of 5%. When the crosslinking agent used in the synthesis of salt-resistant carbomer resin is less than 1.0%, the more the amount of crosslinking agent, the viscosity retention rate μ will increase. When the crosslinking agent increases, the resin will form a tighter shrinkage. Cross-linked grid reduces water absorption and salt tolerance.
