Study of rheological properties of carbomer gels
Original language description
As the optimal basis should be easily applied to the oral mucosa, does not spread and possess medium fluidity, for further studies, we have chosen a carbomer with concentration of 1%. In order to study the strength of the carbomer gel structure as well as to determine the flow type and the thixotropic properties we constructed a rheogram of studied base, showing the dependence of the shear stress tau from velocity gradient Dr. In the investigation of dependence of the structural viscosity on the shear velocity gradient can be seen that the structural viscosity of the studied gel base gradually decreased with increasing shear rate gradient. A result of researchers found that the most active carbomer swelling process occurs between 25 to 30 minutes. Themaximum viscosity observed during the swelling within 30 min. Then, over the entire range of the gel swelling time rheological characteristics are virtually unchanged. Discussions: Was determined the optimal concentration of studied gelli
