introduction | nonoxynyl alcohol ether, also known as Lele ether, is a non-ionic surfactant and is currently the most commonly used external spermaticide. The main function is to reduce the surface tension of the sperm lipid membrane, change the osmotic pressure of the sperm and kill the sperm or cause the sperm to be unable to swim, lose the ability to move, so that the sperm cannot enter the cervix, and the egg cannot be fertilized to achieve the purpose of contraception. |
Pharmacological effects | Nonoxynol ether is a non-ionic surfactant. Its main function is to reduce the surface tension of the sperm lipid membrane and change the osmotic pressure of the sperm. Sperm or cause the sperm to be unable to swim, so that the sperm cannot enter the cervix, cannot fertilize the egg, and achieve the purpose of contraception. The nonoxynol ether contraceptive film is dissolved into gel (about 5min) after being placed deep in the vagina, and the effect is maintained for about 1-2h. The suppository took effect for 10min and the effect was maintained for 2-10h. |
use | nonylphenol polyoxyethylene ether (NPEOn) is the most widely used alkylphenol polyoxyethylene ether, accounting for about 80% of its output. it is the second largest nonionic surfactant after fatty alcohol polyoxyethylene ether (APE). Emulsion polymerization and polymer stabilizers in plastics and synthetic rubbers, textile processing, agricultural chemicals, pulp and paper processes, metal and mineral processing, latex coatings, wetting agents and emulsifiers, foaming agents, inks, Adhesives and medicines, as well as commercial laundry detergents, apartment cleaning products and vehicle cleaning agents. |
Biological activity | 4-Nonylphenol polyethoxylate is a surfactant, often used as a spermicide in contraceptives. |
