The Difference Between Carbomer 980 and 940
Latest company news about The Difference Between Carbomer 980 and 940

Carbomer 980 and 940 are another polymerized acrylate material newly developed by the company after acrylate separation gel. Because of its good thickening, emulsifying, suspending and good transparency, it is widely used in skin care milk In cosmetics such as cream, hand-washing gel, sunscreen, non-alcohol perfume, hair conditioner, etc.

 

Carbomer is a white loose powder, slightly acidic, soluble in water to form a gel, and can produce a high-efficiency thickening effect at a very low dosage (conventional dosage 0.2-1%), thus preparing a very good emulsions, creams, gels and transdermal preparations with a wide viscosity range and different rheological properties; the pH is usually 2.5-4.0 according to the concentration, and it is usually necessary to add a neutralizing agent to adjust the pH to near neutral. Different carbomers have slightly different properties. Compared with 940, carbomer 980 has larger polymer molecules. Under different conditions such as concentration, temperature, pH, etc., its viscosity changes and rheological changes behave differently, each of them has different ionic resistance and shear resistance.

 

 

In addition to the above physical and chemical differences, Carbomer 980 and 940 also have differences in application, such as in skin care lotions or gels:

1. Carbomer 980 behaves in addition to elasticity under dynamic vibration of stress, carbomer 940 is worse but easier to apply evenly.

2. When the presence or concentration of ions increases, the transparency of carbomer 980 and 940 is very small, but the resistance of carbomer 980 to ions is higher than that of carbomer 940, so carbomer 980 can provide a relatively higher viscosity and yield value when the ions increase.

3. The skin feel caused by different carbomers is different. Carbomer 980 has a slight elasticity when it is initially applied and the skin feels moisturized and smooth. It is suitable for medium or partial formulas that feel rich, and it is not sticky after use; It feels clear and suitable for refreshing formula.

 

Desheng Technology has 15 years of experience in the research and development and production of raw materials for acrylic polymer systems. The supply of carbomers 980 and 940 is increasing with each passing day, and the blood collection tube separation gel is also exported to many overseas countries. The rich experience in biochemical reagent synthesis research and development has made its own contribution to the process of replacing imported reagents with excellent domestic reagents.
