Carbomer Factory raw materials are available from stock, transparency> 95%
Carbomer 940 is a white and loose powder. It has high permeability and thickening performance, high transparency, high viscosity, strong suspension capacity, rheological and thixotropy of segments, and low ion shear resistance. Its main characteristics are swelling and slightly acidic. It is widely used in transparent gel, essence and cream products, especially suitable for high transparency products.
 
Functions and uses:
Carbomer 940 has the characteristics of short rheology, high viscosity, high definition, low ion resistance and shear resistance. Its function in the product is mainly reflected in three aspects: thickening, suspension and emulsification. Carbo 940 can produce high viscosity at very low content (conventional dosage 0.25-0.5%). Kappa resin can be used as an excellent suspending agent to suspend the insoluble components in the system. It can also be used as emulsifier to emulsify and stabilize the oil-water phase. In addition, it is also a transparent matrix for cosmetics and an effective water-soluble thickener.
Technical indicators: appearance: loose white, slightly acidic powder
 

 
The dissolution method of carbomer 940 was as follows:
Due to the special structure of carbomer resin, it causes water to expand easily, so it is necessary to set aside time for it to dissolve in water adequately, otherwise the gel produced is easy to join.
First, add the proportioned carbomer 940 (generally about 0.3-0.5%) into the beaker, then moisten it with a little alcohol, and then soak it in water at 80 ℃. Even if it is not stirred for 4-6 hours, it is almost completely dissolved.
Carbomer 940 solution was prepared, and then other components were mixed with carbomer 940 solution, and then neutralized with tea to pH value of 6-7. Because it is not easy to master the amount of triethanolamine, if the amount is too large, the system will become thinner. Therefore, it is recommended to dilute tea into 10% aqueous solution and add it with a dropper. When adding and stirring, you can see that the system becomes more and more transparent and the state is more and more dense, then measure the pH value, which is basically within this range.
 
Use note: after carbomer neutralization, long-term stirring or high shear stirring will cause viscosity loss. The existence of electrolyte will lower the thickening efficiency of carbomer resin, and long-time ultraviolet radiation will reduce the viscosity of carbomer resin.
 
Warm tips: the dispersion time of various types of carbo in water is related to water temperature and water quality. It is recommended to use deionized water. After dissolving, add other ingredients., 940,941, 934, 981 need to be soaked for about 8 hours, and carbo 2020 U10 U20 needs to be soaked for about 4 hours. The specific dissolution time depends on the amount of dissolution.
