VP/VA Copolymers
VP/VA Copolymers produce transparent, flexible, oxygen permeable films which adhere to glass, plastics and metals. Vinylpyrrolidone/Vinyl acetate (VP/VA) resins are linear, random copolymers produced by the free-radical polymerization of the monomers in diferrent ratios.VP/VA Copolymers are available as white powders or clear solutions in ethanol and water. VP/VA copolymers are widely used as film formers because of their film flexibility, good adhesion, luster, water remoistenability and hardness. These properties make PVP/VA copolymers suitable for a variety of industrial, personal care and pharmaceutical products.

Polyquaternium-7
Polyquaternium-7 is a quaternary ammonium compound used as an antistatic agent,fim former and hair fixative,in cosmetics and personal care products,the quaternary nitrogen atom in Polyquaternium-7 always carries cationic charge regardless of the pH of the system.At high pH,the presence of hydroxyl groups may reduce the normally high water solubility of quaternary ammonium compounds.The positive charge on the quats attracts them to the slightly negatively charged skin and hair proteins.Polyquaternium-7 prevents or inhibits the buildup of static electricity and dries to form a thin coating that is absorbed onto the hair shaft. Polyquaternium-7 also helps hair hold its style by inhibiting the hair’s ability to absorb moisture.

Polyquaternium-10
Polyquaternium-10 is a kind of cationic hydroxyethyl cellulose. This polymer has excellent solubility, conditioning ability, adsorption and repairing ability to hair and skin. With its linear polymer structure with positive charges along the backbone, Polyquaternium-10 is a mild conditioner that is compatible with different kinds of surfactants. The unique ability to repair damaged protein substrates make Polyquaternium-10 can be widely used in hair care,hair styling, facial cleanser, body wash and skin care fields. Nowadays, Polyquaternium-10 is still treated as most popular cationic conditioner polymer among all polyquaternium family.

Polyquaternium-11
Polyquaternium-11 is a quaternized copolymer of vinylpyrrolidone and dimethyl aminoethylmethacrylate,
acts as a fixative,film-forming and conditioning agent. It provides excellent lubricity on wet hair and ease of combing and detangling on dry hair. It forms clear, non-tacky, continuous films and helps build body to hair while leaving it manageable. It improves skin feel, provides smoothness during application and skin conditioning. Polyquaternium-11 is suggested for use in mousses, gels, styling sprays , novelty stylers, leave-in conditioning lotions, body care, color cosmetics, and facial care applications. -
Polyquaternium-22
Polyquaternium-22 is a Copolymer of dimethyldiallyl ammonium chloride and acrylic acid.
Polyquaternium-22 is a highly charged cationic co-polymer that is capable of demonstrating both anionic and cationic characteristics.This co-polymer demonstrates excellent pH stability and is ideal for using as conditioning polymers in hair and skin care products.The copolymers are recommended to improve wet and dry properties of hair care products, and to enhance feel in skin care products.Polyquaternium-22 contributes slip, lubricity and richness to form. Improves wet combability in shampoo formulations and also improves the overall manageability of hair. Imparts smooth, velvety feel to the skin and provides excellent moisturization. Exhibits excellent after-bath skin feel and it reduces tightness after drying skin. Bath foam products acquire richer foam with improved stability.
Polyquaternium-22 is used in shampoos, conditioners, bleaches, hair dyes, permanent waves, styling products, moisturizing creams, lotions, bath products, shaving products and soaps. -
Polyquaternium-28
Polyquaternium-28 forms clear, glossy films that are flexible and tack-free. It is water soluble, stable to hydrolysis at low or high pH (3-12), and compatible with anionic surfactants, as well as nonionic and amphoteric. Its cationic nature gives substantivity to hair and skin, providing conditioning and manageabiliy with minimum build-up. Polyquaternium-28 improves wet combability of hair and has good curl retention performance for styling products.
-
Polyquaternium-39
Polyquaternium 39 is a liquid polymer that is compatible with anionic and amphoteric surfactants. When used in hair care products if contributes luster and a soft, silky feel. It will provide sheen when the hair has dried and will reduce static. It provides excellent moisturisation and adds improved stability to the richer, thicker foam of cleansing products.
