LUVISKOL VA 73 W is a water-based copolymer dispersion primarily composed of vinylpyrrolidone (VP) and vinyl acetate (VA).
LUVISKOL VA 73 W is widely used in cosmetic and personal care formulations as a film-forming and hair-fixing polymer.
LUVISKOL VA 73 W provides strong hold, flexibility, and improved styling performance while maintaining a natural feel.
LUVISKOL VA 73 W forms transparent, flexible films on hair surfaces, delivering long-lasting fixation without excessive stiffness or flaking.
Due to its balanced VP/VA ratio, LUVISKOL VA 73 W offers good humidity resistance and compatibility with a broad range of formulation systems.
LUVISKOL VA 73 W is typically supplied as an aqueous dispersion, making it easy to incorporate into alcohol-free or low-alcohol hair styling products.
LUVISKOL VA 73 W is commonly used in hair sprays, styling gels, mousses, setting lotions, and other hairstyling preparations where durable hold and gloss enhancement are required.
LUVISKOL VA 73 W resin is a 50% solution of a copolymer of vinylpyrrolidone and vinylacetate in water.
LUVISKOL VA 73 W is a film-forming agents and fixatives in hair care, particularly in aerosol sprays, pump sprays, liquid products, mouses and gels.
LUVISKOL VA 73 W is an easy-to-use aqueous solution that is compatible with carbomers, and is particularly suitable for alcohol-free formulations, forming a clear solution in water.
LUVISKOL VA 73 W has a K-Value (1% in ethanol) of 24.0-32.0, a solids content of 48.0-52.0%, and a water content of approx. 50%.
LUVISKOL VA 73 W is a film-forming and binding polymer containing PVP/VA (Polyvinylpyrrolidone/Vinyl Acetate) copolymer.
Because its VA ratio is higher than VA 64 W, LUVISKOL VA 73 W provides stronger hold and a more durable film structure.
LUVISKOL VA 73 W is particularly preferred in hair styling cosmetic products.
LUVISKOL VA 73 W is a film-forming agents and fixatives in hair care, particularly in aerosol sprays, pump sprays, liquid products, mousses and gels.
LUVISKOL VA 73 W is an easy-to-use aqueous solution that is compatible with carbomers, and is particularly suitable for formulations without alcohol, forming a clear solution in water.
Applications of LUVISKOL VA 73 W:
The LUVISKOL VA grades are used in hair care and styling preparations as fixatives and film-forming agents.
They possess excellent properties both for aerosol sprays and for non-aerosol products.
The VA 37 and VA 55 grades are particularly suitable for hairsprays.
For liquid setting lotions, gels and mousses, we can recommend the VA 64 and VA 73 grades.
With increasing vinylpyrrolidone content, the LUVISKOL VA grades become more hygroscopic.
This gives them stronger adhesion to the hair, but their washing-out and combing-out properties remain excellent because of the nonionic nature of the polymer.
