SA NanoGel uses a supramolecular structure formed by a poloxamer segment copolymer to achieve the encapsulation of salicylic acid. Poloxamer gel improves the solubility of salicylic acid, and the sustained- release effect reduces the irritation of salicylic acid. Poloxamer non-ionic block polymer structure can improve the permeability to the skin. S alicylic acid 30% is commonly used to remove warts, corns, calluses and hyperkeratosis, not for daily skin care.
The encapsulation is mainly achieved through the molecular entanglement of temperature- sensitive nonionic surfactants,without the formation of new compounds.
