Because of its
very good thickening and suspending properties, carbomer is usually
made into gel and used in various daily chemical products,
biochemical experiments and pharmaceutical excipients. In high-end
skin care products or pharmaceutical excipients, carbomer gel is
required to be sterile, and it cannot promote bacterial growth or
sterilization, so it needs to be sterilized.
Carbomer
Irradiation Sterilization
Sterilization by
Co*0 irradiation is a common sterilization method. However, because
the carbomer is irradiated, the structure will change and the
viscosity will decrease to varying degrees. Before irradiating the
carbomer solution for sterilization, add A proper amount of
glycerin can prevent the structure of carbomer from being
destroyed, thus greatly improving the wide application of
carbomer.
Â
Carbomer
moist heat sterilization
Carbomer is
treated by moist heat sterilization, that is, carbomer powder is
usually made into carbomer solution and then sterilized. However,
carbomer powder is easy to form a high-viscosity gel in water, and
when it is scattered in vigorously stirred water, it hydrates
slowly and tends to form a lumpy shape. When it is sterilized by
moist heat, it cannot achieve good results due to uneven heat
dispersion. Sterilization effect. In addition, after turning into a
gel, the carbomer solution has a high viscosity and poor fluidity,
and it cannot be sterilized by microporous membrane filtration or
sterilized by Co *0 irradiation.

Carbomer
alkali metal salt sterilization
Adding alkali
metal salt and/or alkaline earth metal salt to the carbomer
solution can prepare a carbomer solution with qualified
microorganisms and good fluidity, and control the environmental
microbial load during the preparation process, which is widely used
in the preparation of sterile preparations . The alkali metal salt
is an inorganic salt of an alkali metal, such as one or more of
alkali metal nitrate, alkali metal sulfate and alkali metal
chloride. The available options are sodium nitrate, sodium sulfate,
sodium chloride, potassium nitrate, Potassium sulfate, potassium
chloride, etc.; alkaline earth metal salts are selected from one or
more of magnesium nitrate, magnesium chloride, calcium nitrate,
calcium chloride, barium nitrate and barium chloride. First, the
alkali metal salt solution is filtered through a 0.***0.*5μm filter
element to effectively remove pathogenic microorganisms. Carbomer
is added to dissolve it and sterilized at ******0 degrees for *5=*0
minutes.
Â
The above-mentioned different carbomer
sterilization methods have their own characteristics, and the
sterilization method can be selected according to the different
uses of carbomer. Desheng has rich experience in the synthesis and
production of acrylic polymers, and can provide high-transparency
and high-quality carbomer raw materials.
