Carbomer 940 is a cross-linked polyacrylate polymer, which can produce high viscosity and can form a transparent gel. It has important uses such as thickening and suspension. It has a short process (no drip). Simple, good stability, widely used in transparent gel, essence and cream products, especially suitable for highly transparent products.

Description:
Carbo 940 has the characteristics of short rheology, high viscosity, high clarity, low ion resistance and shear resistance. Its role in the product is mainly reflected in three aspects: thickening, suspension and emulsification. Carbo 940 can not produce higher viscosity when the content is very low (normal dosage is 0.25-0.5%). Carbo resin can be used as an excellent suspending agent to suspend insoluble components in the system; it can also be used as an emulsifier to emulsify and stabilize in the oil/water phase. In addition, it is also a transparent base for cosmetics. It is also an effective water-soluble thickener
There are still many specification carbomer product, like carbomer 941, carbomer 934, carbomer 980, carbopl 2020 etc.
1. Carbomer is a cross-linked acrylic polymer, which swells in water and adds a small amount of neutralizing agent (
Such as: in the case of neutralizer and neutralizer 2), a highly transparent gel is formed. Carbomer has different models.
The table has different viscosity, short rheology or long rheology. For example: Carbomer 940 has short rheological properties, and the viscosity reaches 63000MPA.S at 0.5%. It is suitable for products with high viscosity. Carbomer 941 has long rheology. Performance, at 0.5% viscosity up to 7500MPA.S is suitable for low-viscosity products, carbomer corresponding models have ion-resistant and ion-resistant performance, daily chemical industrial products.
2. Method of dissolving carbomer:
A: Pre-soaking method: 24 hours in advance, the carbomer should be added in the removal according to actual production requirements
Dissolve in the sub-water without stirring. After the carbomer naturally absorbs water, there is no whiteness on the surface.
Color powder, the solution does not see white agglomerates, whichever is the case, stir evenly, and then add the neutralizer (card
Wave: Neutralizer = 1: 1, Carbo: 5% Neutralizer solution = 1.4.5) Adjust the PH value to about 7 to reach the thickening state, use a circular tool or a disperser, and stir evenly at low speed.
B: The homogenizer is added to the homogenizer according to the actual production ratio, and no white masses can be seen in the homogenizer, add
After the neutralizer has formed a gel, use a vacuum emulsifying pot to remove the air from the gel.
If you use common methods to dissolve carbomer and add it to water, you can't stir it. For example, adding and stirring will make carbomer form a white water ball. The surface has absorbed water but no water can be absorbed inside. After neutralization, you can see a lot of water. The water has white spots and a large number of bubbles are formed. The carbomer viscosity is high, and the bubbles are difficult to eliminate by themselves. Even if the defoamer is added, it is difficult to eliminate the air bubbles.
