Do you
know the precautions for using carbomer
Â
Carbomer is
generally affected by temperature, electrolyte, ultraviolet light,
and other factors.
Â
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.
Â
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.
Â
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.
