Do you know the precautions for using carbomer
 
Carbomer is generally affected by temperature, electrolyte, ultraviolet light, and other factors.
 
The effect of temperature on carbomer is as follows: when the temperature rises, the movement between molecules intensifies and the molecular kinetic energy increases. Due to the difference in the volume of the gel molecule and the water molecule, the movement frequency of the two is inconsistent. In this case, as the temperature rises, the hydrogen bond between the gel molecule and the water molecule is broken, resulting in carbomer condensation. The glue viscosity is reduced.
 
The influence of electrolyte on the carbomer gel is as follows: ions will have a great impact on the viscosity of the carbomer gel, and subtle changes in ion concentration can directly cause a drastic change in the concentration of the carbomer gel, which further affects the entire card. Rheology of Pomm Gel. The greater the concentration of electrolyte, the viscosity of carbomer gel will drop significantly.

Common problems in the use of carbomer
1. Carbomer dissolves into agglomerates: This is because carbomer has strong hydrophilicity. The powdered carbomer has very strong hygroscopicity. Like other hygroscopic powders, when used improperly, put it into In water or other polar solvents, it is easy to form agglomerates or incompletely wet. The other powders will eventually decrease and dissolve after forming agglomerates, but the carbomer is not easy to dissolve after forming agglomerates, because once the outer layer of the agglomerates is completely infiltrated, the water will not easily penetrate into the internal dry part, and finally agglomeration will appear.
 
2. Carbomer gel transparency is reduced: This is because in some gels, ethanol is often added as an additive in order to increase permeability, antiseptic and solubilization, such as disinfection and disposable gel, in which ethanol is the main component and content Or it can be as high as about *5%. Carbomer gel is essentially a polymer solution. The reason why the polymer solution is stable is that there is a hydration film on the surface of the particle. The addition of a strong hydrophilic non-electrolyte (such as ethanol) will cause the polymer solution to flocculate. Carbomer ethanol gel is prepared by different operating processes, and the ethanol concentration of the finished product is different. When the ethanol concentration is too high, the finished gel will produce a little opalescence and reduce the transparency of the gel.
