Overview
Polidocanol is a synthetic nonionic surfactant and local anesthetic with sclerosing properties. It is widely used in medical applications, particularly for treating varicose veins through sclerotherapy. The compound is also employed in cosmetic procedures and pharmaceutical formulations due to its ability to disrupt cell membranes and induce fibrosis. First introduced in the 1960s, polidocanol has gained recognition for its efficacy and safety profile when administered by trained professionals. Its dual functionality as an anesthetic and sclerosing agent makes it a versatile tool in minimally invasive treatments.
Physical and Chemical Properties
Polidocanol is a viscous liquid at room temperature, typically colorless to pale yellow. It is soluble in water, alcohol, and ether, which facilitates its formulation in injectable solutions. The compound's molecular structure includes a long hydrocarbon chain with multiple ethoxy groups, contributing to its surfactant properties. As a nonionic surfactant, polidocanol reduces surface tension and disrupts lipid membranes, which is critical for its sclerosing effects. Its stability under normal storage conditions makes it suitable for pharmaceutical use, though prolonged exposure to heat or light should be avoided.
Main Applications
The primary use of polidocanol is in sclerotherapy, where it is injected into varicose veins to collapse and seal them. This minimally invasive procedure is favored for its high success rate and low complication risk. The compound's anesthetic properties also minimize discomfort during treatment. Beyond sclerotherapy, polidocanol is used in cosmetic dermatology for treating vascular lesions and in pharmaceutical formulations as a stabilizer or emulsifier. Its versatility and safety profile have led to ongoing research into additional medical applications.
Safety and Storage
Polidocanol should be handled with care, as improper use can lead to allergic reactions or tissue irritation. Medical-grade formulations must meet strict purity standards, and administration should only be performed by qualified professionals. Proper storage in a cool, dry environment is essential to maintain stability. Safety data sheets (SDS) and certificates of analysis (COA) should be reviewed before procurement. In case of accidental exposure, rinse affected areas thoroughly and seek medical advice if symptoms persist.
B2B Procurement Guide
When sourcing polidocanol, buyers should prioritize suppliers with pharmaceutical-grade certifications and transparent documentation. Key considerations include CAS number verification, purity levels (typically 95-99%), and compliance with regional regulatory standards such as USP or EP. Bulk procurement may offer cost advantages, but storage capacity and shelf life should be factored in. Request samples for quality testing and ensure suppliers provide batch-specific COAs. Pricing varies based on quantity and supplier reputation, so compare options carefully.
