Denture adhesive raw material Calcium/Sodium PVM/MA Copolymer mixed salts

Details:

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.

Benefits:

Gives long-lasting hold for efficacy.

Not made with Zinc.

Swells in water or saliva to produce a tacky,high viscosity,elastic mass that gives excellent wet adhesive strength.

Crosslinks through ion bridges to increase its cohesive strength and viscoelasticity.

Applications:Oral Care/Denture Adhesives,Wound Care

This polymer 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.

Recommended Dosages:25~40% denture adhesive cream,20~80% denture adhesive powder,5~10% starting point for ostomy applications.

Temperature/mixing conditions:For denture adhesive creams,add at 65~75 ℃ under dry conditions.For powder formulations,add at room temperature under dry condistions.

Adding Time:For denture adhesive creams,add it after dispersing Cellulose gum in petrolatum and mineral oil base.For ostomy adhesvies,it is suggested addition take place together with the Hydrocolloids in the fomulation.

Tips:For Denture adhesive cream,use a mechanical mixer to disperse powders into a petrolatum and mineral oil base at a temperature 65~75 ℃,Mix the cream at leaset 30 minutes to achieve uniform dispersion of powders in the base followed by cooling to 20~30 ℃.
