Cat. No.: HY-Y0850U5
CAS No.: 9002-89-5
Synonyms: Polyvinyl alcohol (Mw 27000, 98-99% hydrolyzed, ~600 polymerization); Poly(Ethenol) (Mw 27000, 98-99% hydrolyzed, ~600 polymerization)
PVA (Polyvinyl alcohol) (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) is a nonionic ethanol homopolymer with hydrophilicity, water solubility and biodegradability. PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) exhibits biocompatibility, non-toxicity and non-carcinogenicity, as well as antibacterial activity against Gram-positive bacteria, Gram-negative bacteria and fungal strains. PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) can serve as a solubilizer, stabilizer, mucoadhesive agent and sustained-release agent, and has a synergistic solubilizing effect on voriconazole/sulfobutyl ether β-cyclodextrin complexes. By stabilizing such complexes, PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) forms freeze-thaw hydrogels with high mucoadhesion, sustained drug release and ex vivo corneal permeability. When compounded with hyaluronic acid hydrogels, PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) supports chondrocyte growth in vitro, and also forms complexes with Cu 2+, Co 2+, Ni 2+ and Zn 2+ ions. PVA (Mw 27000, 98-99% hydrolyzed, ~600 polymerization) can be used in studies related to fungal keratitis, bacterial infections and fungal infections .

Cetylamine (Hexadecylamine) is an amphipathic hexadecyl alkylamine. Cetylamine enhances phase separation of aqueous PVA solutions, promotes the formation of PVA crystalline domains while remaining amorphous itself, and enables the preparation of surfactant-free, solvent-free, and crosslinker-free PVA hydrogels via freeze-thaw blending. Cetylamine can serve as the cationic surfactant component in ion-crosslinked micelles, which can load hydrophobic drugs and deliver them to breast cancer cells. Cetylamine is applicable to breast cancer-related research .

PVA (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization)
PVA (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization)
0 Images
Cat. No.: HY-Y0850U2
CAS No.: 9002-89-5
Synonyms: Polyvinyl alcohol (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization); Poly(Ethenol) (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization)
PVA (Polyvinyl alcohol; Poly(Ethenol)) (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization) is a non-toxic, biodegradable, and highly biocompatible semicrystalline synthetic polymer. PVA (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization) acts as a coating agent to improve tableting performance, and can be cross-linked with sodium trimetaphosphate to prepare tubular vascular grafts or form hydrogels for use as artificial articular cartilage and sustained-release matrices for growth factors. PVA (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization) enhances the redox cycle of iron species in photo-assisted Fenton reactions to simultaneously generate hydrogen peroxide and degrade pollutants, enabling integrated sustainable waste management and water treatment. PVA (Mw 130000, 87-89% hydrolyzed, ~2700 polymerization) is used in the manufacture of biodegradable films and in studies of dry or minimally invasive ex vivo wounds, but cannot form freeze-thaw cross-linked solid sheets for wound dressings .
