Differences between carbomer 940 and carbomer 2020

As we all know, Carbomer belongs to acrylic resin. As a kind of high-quality thickener raw material for cosmetics, it has the remarkable characteristics of thickening, suspension, emulsification and pseudothixotropy. According to the customer's search needs, Carbomer 940 and carbomer 2020 are the most popular thickeners. Desheng technology, as a professional manufacturer of carbomer series products, has a professional R & D team and mature production technology. The following is a brief summary of the differences in performance characteristics between carbomer 940 and carbomer 2020.

First of all, let's understand some common features of Carbopol resin

1. Swelling: Kaposi resin is hydrophilic in acidic form and easy to swell in water and polar organic solvents.

 

2. Weak acidity: Kaposi resin is an acrylic polymer containing polyether crosslinking. Because of 56% - 68% carboxylic acid group in the molecule, these resins are weakly acidic. Although they are weaker than acetic acid, they are easy to react with inorganic bases and organic bases to form salts.

 

3. Functions and uses: Carbopol resin can be used as excellent suspending agent, stabilizer, emulsifier, transparent matrix of high-grade cosmetics and pharmaceutical excipient matrix, and is also the most effective water-soluble thickener.

 

Performance characteristics of carbomer 2020:

Carbomer 2020 is an easily wettable hydrophobically modified acrylic (ester) cross-linked polymer. As a water-soluble rheological modifier, it not only has the functions of thickening and suspension, but also has a short wetting time in water, which is better than carbomer 940 and more convenient to use. In addition, it has excellent salt resistance and is compatible with surfactants It can be used in the formula containing electrolyte, but carbomer 940 is not ion resistant and cannot exist in the strong electrolyte system. Applications: skin care emulsion, cream, alcohol based transparent gel products, transparent skin care gel, hair styling gel, shampoo, shower gel.

 

Features of the carbomer 940:

Carbomer 940 is a white loose powder with strong hygroscopicity. The pH of 1% aqueous dispersion is 2.5-3.0. Gel can be neutralized by alkaline substances.

 

After carboxy group is ionized by carbomer neutralization, the molecular chain is dispersed and extended due to mutual repulsion of negative charges, showing a state of great expansion and viscosity. The effective thickening range of the hydrogel system is within PH5-10. Application: Carbopol 940 can be used as excellent suspending agent, stabilizer and emulsifier. Carbopol resin can be used as transparent matrix of high-grade cosmetics and pharmaceutical excipient matrix. Carbopol resin is also the most effective water-soluble thickener.

 

In cosmetic gel, water must be soaked or taken for a long time, because carbomer 940 has a swelling process with water, and the time is too short to dissolve the ball. Secondly, we need to see if other components in the system contain electrolytes. Many natural plant components basically have electrolytes, such as flower water, extract, plant extract and so on. When there is electrolyte, it is necessary to select ion resistant thickener carbomer 2020; if there is no electrolyte problem in the system, Carbomer 940 can be selected.

Therefore, in the cosmetic configuration, Carbomer 940 and carbomer 2020 are widely used as thickening agents. General cream (no strong electrolyte) is mainly used in carbomer 940, while carbomer 2020 is mainly used in skin care emulsion, cream, alcoholic transparent gel products, transparent skin care gel, hair styling gel, shampoo and Shower Gel.

 

Desheng technology is a professional manufacturer of cabom, with advanced production equipment and mature production technology, with an average daily output of tons. The carbomer powder produced by the company is whiter and more fluffy than that on the market, with better transparency after dissolution. According to the customer response, the effect of product use is good, can support free application sample trial, welcome to inquire and order!
