Product Details

TNJ Chemical is top cosmetic pharmaceutical grade PVP K90 PVP K30 suppliers (factory as well as K15 K17 K25 K60 K120) in China since from 2001. If you want to buy PVP K90 in powder or solution, please feel free to contact us. As a top PVP K90 suppliers, we guarantee good quality and competitive price.

PVP K90 powder has two obvious characters: high viscosity and high hygroscopicity. This two characters make PVP K90 powder an excellent materials for cosmetics. PVP K90 powder exists in white powder or aqueous solution. PVP readily dissolves in water, alcohol, amine and halohydrocarbon, but is not dissolved in acetone and aether etc.. It has good solubility, biocompatibility, and physiologically inert, film-forming character, colloid protect ability and compound ability to many organic or inorganic compounds. It is also steady to acid, salt and heat, so it is widely used.

Application

In Pharmaceutical Industry

PVP-K possess excellent adhesive,film-forming,dispersing and thickening properties,and are widely used in the pharmaceutical industry.

Low molecular weight PVP-K, often used as a solubilizing agent, crystallization inhibitor and suspension stabilizer in injection and ophthalmic formulations such as PVP K12,K15,K17.

Medium Molecular PVP-K, often used as binder in tablets,capsules and granules, as a stabilizer for oral suspensions,film-forming agent,solubilizing agent, dispersant for pigments, as an enzyme stabilizer and to improve bioavailability such as PVP K25,K30.

High molecular PVP-K, as highly effective binder, often used as stabilizer in oral and topical suspension, as a thickener, hydropylizing agent such as PVP K90.

In Cosmetic Industry

PVP-K are used widely in a wide range in hair care, skin care & oral care products.The products are particularly suitable for formulations where viscosity modification and film forming properties are required. PVP-K products are particularly suited to hair styling products. The medium molecular weights such as PVP K30 are preferred where viscosity is critical in applications, for example, spray. The higher molecular weight products such as PVP K90 are the best choice where high viscosity are required in applications. PVP-K is widely used in cosmetics as followings

*Hair Gels

*Hair mousses

*Liquid hair setting preparations

*Pump Sprays

Industrial Application

* Suspensant, disperser and emulsifier

* Glass fiber

* Detergent

* Plastics and resin
