Major Application
In cosmetics: T-20 is mainly used as a solubilizer, penetrant and dispersant for pharmaceuticals and cosmetics in daily chemicals. Emulsifiers can improve the structure of crystalline substances, stabilize bubbles and aeration; reduce the surface tension of liquids and solids, so that liquids quickly diffuse to all surfaces, and are effective lubricants; demulsification and defoaming; improve the stability of emulsions .
In medicine: it is a non-ionic surfactant with strong hydrophilicity and chemical non-dissociation, and it has a good solubilizing effect on drugs. It is often added in pharmaceutical preparations to increase the amount of active ingredients. Solubility; on the other hand, Tween 20 can inhibit the automatic polymerization of macromolecular protein drugs and improve the stability of drugs.
