Literatures about gels around recent years were consulted and combined with practical experimental experiences to sort and summarize literatures about studies and applications of novel excipient carbomer in gel preparations

then detailed introduction structure characteristics

physical and chemical properties

thickening mechanism

preparation methods

formulation design and clinical applications of carbomer

this study will provide theoretical basis for promotion and application of carbomer in industrial production.At the same time

carbomer would be a promising and novel pharmaceutical excipient

with introduction of new technologies and methods

it would give more dosage forms and inspirations to topical preparations of traditional Chinese medicine.
