Description of Poloxamer 407
Poloxamer 407 is a synthetic block copolymer of ethylene oxide and propylene oxide. It is available in several types. This kind of surfactant were firstly developed by America.They have almost no toxicity, little irritation on the skin and the mucosa. They are widely used as emulsifier, solubilizing agent, hydrophilic substrate of ointments and suppositories,artificial blood, artificial tear and artifical skin etc.
