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-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.
-
Polyquaternium-47
Polyquaternium-47 is an aqueous solution of an amphoteric terpolymer consisting of acrylic acid, methacrylamidopropyl trimethyl ammonium chloride and methyl acrylate. It is compatible with most anionic and amphoteric surfactants. In hair care products, it offers conditioning, detangling, wet reduces tightness after drying skin. Provides excellent moisturization and lubricity. Liquid cleansing products acquire richer, thicker foam with improved stability. Contains sodium benzoate as a preservative.

Guar Hydroxypropyltrimonium Chloride
Guar Hydroxypropyl Trimonium Chloride is a kind og cationic guar gum. Guar Hydroxypropyl Trimonium Chloride is a water-soluble quaternary ammonium derivative of native guar gum. It gives conditioning properties to shampoos and after-shampoo hair care products. The effects of the cationic charge density, guar concentration in aqueous solution, and treatment time on hair have been studied. YR Chemspec Guar Hydroxypropyl Trimonium Chloride is able to improve the ease of combing significantly, and delivers an outstanding softness, rich sensorial hair feel to customers.

Hydroxyethyl Cellulose
Hydroxyethyl cellulose (HEC) polymer is a hydroxyethyl ether of cellulose, obtained by treating cellulose with Sodium Hydroxide and reacting with ethylene oxide. HEC polymers are largely used as water-binder and thickening agent in many industry applications, that is, personal care products, pharmaceutical formulations, building materials, adhesives, etc., and as stabilizer for liquid soaps. They are available as white free-flowing granular powders that easily dissolve in cold and hot water to give transparent solutions with varying viscosities depending on polymer concentration, type and temperature.
