Cas No. :62386-95-2
Quantity: 2000Metric Tons Specs:Cosmetic Grade 1.Poly(Methylvinylether/Maleic Acid) Mixed Salts Copolymer INCI Name:Calcium/Sodium PVM/MA Copolymer CAS NO.:62386-95-2 Properties:The copolymer supplied in powder form, is slowly soluble in water resulting in amber-colored solutions with high viscosity and adhesivity. It is used as a bioadhesive in denture adhesives, and as mucoadhesive for drug delivery to mucous membranes.And the Calcium salt bridges enhance cohesive properties.It's excellent Wet adhesive strength,Long-lasting Hold,Mucoadhesive that enables delivery to mucous membranes. Applications:The copolymer can be used directly in the formulation of a denture adhesive. In denture adhesives the salts provide excellent wet adhesive strength and duration of hold.It's an outstanding oral mucosal adhesive,suitable for denture adhesive formulations.The ionic bridges inside the copolymer molecule results in both adhesive and cohesive adhension to generate long lasting and durable denture adhesive systems.It acts as an adhesive cushion between the denture and gums to strong adhere to the gums and reduce the likehood for irritation due to a loose fitting denture.This copolymer is an essential component in the denture adhesive,such ingredient can help people abtain natural and comfortable feeling from their dentures. 2.Poly(Methylvinylether/Maleic Acid)Copolymer INCI Name:PVM/MA Copolymer CAS NO.:25153-40-6 Properties:These polymers are free acid form of the copolymer of Methylvinyl ether and Maleic Anhdride,in liquid form and powder form.Avalilable in a range of Molecular weights with tunable rheological properties.Those polymers soluble in water,serve as excellent film formers and bioadhesive/mucosal adhesives. Applications:These Copolymers are available for use in hair care and oral care products.In toothpaste and mouths rinses,it helps control formation and growth of tartar,prtects enamel from dietary acid and retains active ingredients.The strong bioadhesive founction of the polymer retains antimicrobical agents,flavors,coolants,breath fresheners,medicants and other insoluble actives in the mouth. 3.Poly(Methylvinylether/Maleic Anhydride)Copolymer INCI Name:PVM/MA Copolymer CAS NO.:9011-16-9 Properties: Insoluble in water , soluble in THF , Acetone , etc.Hydrolysis happens in water under proper condition.For production of di-acid products and half ester products. Applications:The polymer series serves as a base polymer for making bioadhesives in denture adhesive applications. The polymers are not directly usable in a denture adhesive formulation. 4.Poly(MethylvinyletherMaleic Acid) Half Esters Copolymer INCI Name:Ethyl Esters of PVM/MA Copolymer,Butyl Ester of PVM/MA Copolymer CAS #:25087-06-3,25119-68-0 Properties:Both types are the copolymers of Monoalkyl ester of poly (methyl vinyl ether/maleic acid),the products forms tough, clear glossy films. Films exhibit tack-free adhesion, have excellent substantivity, and moisture resistance. Soluble in alcohols, esters, ketones and glycol ethers and have good compatibility with aerosol propellants. Applications:Both Products can be used in aerosol and pump hairsprays,gels,mousses,styling lotions/creams,styling sprays(non-aerosol)and novelty stylers.They can also be used in both low and high VOC formulations. It provides excellent shine, good style retention and humidity resistant. It also aids pigment dispersion and emulsion stabilization. |
