This article is an attempt to compare six surfactants for injection

such as polysorbate 80

polyoxyethylene castor oil derivatives

poloxamer188

lecithin

Solutol HS 15

cyclodextrins

from various countries’ standards of pharmacopoeias and respectively gives an overview of their chemical compositions

physical appearance

incompatibility of medicines and safety

which provides reference data for new drug research and clinical study of injections.As for the surfactants for injection that are not recorded in the chinese pharmacopoeia（2005）

we suggest that we introduce those foreign surfactants and make corresponding quality standards by referring to foreign standards.
