Request SDS →VP/VA copolymer (INCI: VP/VA Copolymer; also called PVP/VA copolymer; CAS 25086-89-9) is a film-forming copolymer of N-vinylpyrrolidone (VP) and vinyl acetate (VA) used mainly as a hair-fixative and styling resin. The VP:VA ratio is the lever that tunes the dried film: more VP gives easier wash-out and a softer feel but greater humidity sensitivity, while more VA gives a stiffer, more humidity-resistant, harder-hold film that is less water-soluble.
Applications by sector
VP/VA copolymer earns its place across formulations because a single resin delivers clear film, adjustable hold, and gloss without a separate plasticizer in many systems. The same VP-to-VA chemistry that sets hold on hair also governs how a film behaves on skin or as a binder.
Hair styling — gels, sprays, mousses, pomades
This is the workhorse use. The polymer dries to a continuous film that welds hair fibers at contact points, holding the style while staying flexible enough to resist flaking. In aerosol and pump hairsprays, mid-range grades (roughly a 60/40 VP:VA balance) give firm hold with good propellant compatibility and curl retention in humidity. Gels and mousses use it for build and gloss; pomades and creams use lower-VP, higher-VA grades where a stiffer, more moisture-resistant film matters. The practical reason formulators reach for it: hold strength is dialed by grade selection, not by overloading the formula.
Conditioners and leave-ins
At lower use levels the resin deposits a light film that adds slip, body, and shine and helps anchor other actives on the fiber. Higher-VP grades are preferred here because they rinse and re-wet more readily, avoiding the heavy build a high-VA grade would leave.
Skin, sun, and color cosmetics
As a film former it improves wear and transfer resistance in mascara, eyeliner, foundation, and sunscreen, and helps hold pigment and UV filters in place on the skin. Grade choice trades a more durable, water-resistant film (higher VA) against an easier-to-remove one (higher VP).
Pharmaceutical and industrial binder / film former
The same film-forming and binding behavior is used as a tablet binder and granulation aid and in coatings and adhesives, where it contributes adhesion and a clear, cohesive film. Confirm the appropriate grade and documentation for regulated uses.
How the VP:VA ratio changes performance
The single most useful thing to understand about this material is the ratio trade-off. The figures below are the generic, directional relationships across the VP:VA range — specific values are grade-dependent and confirmed on the Certificate of Analysis.
| VP:VA ratio | Hold strength | Film flexibility | Humidity resistance | Water solubility |
|---|---|---|---|---|
| High VP (e.g. 70/30) | Lower / softer hold | Higher (more flexible) | Lower (more humidity-sensitive) | Higher (easier wash-out) |
| Balanced (e.g. 60/40) | Firm, all-purpose hold | Moderate | Moderate | Moderate, still water-removable |
| High VA (e.g. 30/70) | Higher / stiffer hold | Lower (firmer film) | Higher (more humidity-resistant) | Lower (more water-resistant) |
Mechanism in one line: VP units are hydrophilic and VA units are hydrophobic, so raising VA lowers the film’s affinity for water — better hold in humid air, harder to rinse out — while raising VP does the reverse.
Forms and grades
VP/VA copolymer is supplied as a free-flowing powder or as a solution (commonly in ethanol or water). It dissolves in both water and alcohol, which is why it drops cleanly into aqueous gels and alcohol-based aerosol sprays alike. Available VP:VA ratios and the exact form, solids content, and K-value are grade-specific; request the CoA for the grade you intend to use so the ratio and solubility match your process.
Handling and documentation
Store sealed and dry — powder grades are hygroscopic and will cake if exposed to moisture. Always work from the current Safety Data Sheet for the specific grade; the SDS governs handling, PPE, storage, and disposal. Request the SDS and CoA with your quote.

Frequently Asked Questions
What is VP/VA copolymer used for?
VP/VA copolymer (CAS 25086-89-9) is a copolymer of N-vinylpyrrolidone and vinyl acetate used as a film former and binder. It is best known as a fixative and styling resin in hair-care products (gels, sprays, mousses, pomades) and is also used in skin and color cosmetics, sunscreens, pharmaceutical binders, and coatings and adhesives.
Is VP/VA copolymer good for hair?
Yes — it is one of the most widely used hair-fixative resins. It dries to a clear, flexible film that holds the style while resisting flaking, and the VP:VA ratio lets formulators dial hold strength and humidity resistance. Higher-VA grades give firmer, more humidity-resistant hold; higher-VP grades wash out more easily.
Is VP/VA copolymer water soluble?
It is soluble in both water and alcohol, which is why it works in aqueous gels and in alcohol-based aerosol sprays. Water solubility falls as VA content rises: high-VP grades wash out readily, while high-VA grades form a more water-resistant film. The exact solubility is grade-dependent and confirmed on the Certificate of Analysis.
What does the VP/VA ratio mean?
The ratio is the proportion of vinylpyrrolidone (VP) to vinyl acetate (VA) in the copolymer, for example 70/30, 60/40, or 30/70. VP is hydrophilic and VA is hydrophobic, so a higher VP fraction gives a softer, more flexible, more water-soluble film that is more humidity-sensitive, while a higher VA fraction gives a stiffer, harder-hold, more humidity- and water-resistant film. The ~60/40 grade is a common all-purpose balance.
Is VP/VA copolymer a plastic?
VP/VA copolymer is a synthetic polymer (a copolymer of N-vinylpyrrolidone and vinyl acetate) supplied in primary form, classified under HS 3905.91. It functions as a film-forming resin rather than a molded plastic, forming thin films when dried in a formulation.
What grades or VP:VA ratios are available?
VP/VA copolymers are produced in different VP:VA ratios and in solution or powder forms, which control film stiffness, moisture resistance, and solubility. The specific grade, ratio, solids content, and form are confirmed on the Certificate of Analysis; request the CoA and SDS for the grade you need.
How is bulk VP/VA copolymer packaged and priced?
It ships in bulk as powder or solution in drums, pails, and supersacks for personal-care, cosmetic, pharmaceutical, and coatings manufacturers. Packaging, MOQ, and pricing are volume- and grade-dependent; submit a bulk RFQ.
