    摘要: Methods for making granules containing a carbomer whereby the carbomer is mixed with a hot-melt binder that does not lower the glass transition temperature of the carbomer more than 20° C., the binder is subjected to a temperature at which the hot-melt binder melts or becomes tacky, thus binding the carbomer to form an agglomerated powder, and permitting granules to form from the agglomerated powder. This subjecting of the binder to the temperature may be after the binder is mixed with the carbomer or the carbomer may be mixed with the binder at a time when the binder is at a temperature at which it will melt or become tacky. The granules may contain a biologically active substance either intragranularly or extragranularly and may be used to make personal care products or pharmaceutical dosage forms, such as controlled release dosage forms which may have bioadhesive properties.
