Povidone K90 Pharmaceutical Grade is a pharmaceutical-grade white powder with excellent water solubility, film-forming properties, and adhesiveness. It is commonly used for binding tablets and capsules, thickening and stabilizing liquid formulations, and meets USP/EP/BP standards. It is a key excipient in pharmaceutical formulations.
Premium Povidone K90 Pharmaceutical Grade Details
High Molecular Weight & Viscosity: K90 is a high molecular weight grade with high viscosity, effectively improving the adhesion and film-forming properties of formulations, making it suitable for formulation systems requiring high structural strength.
Excellent Solubility & Compatibility: Easily soluble in water and many common pharmaceutical solvents, it exhibits good compatibility with various active ingredients and excipients, offering high formulation flexibility.
Reliable Binding & Film-Forming Performance: Widely used as a tablet binder, film coating, and stabilizer, it helps improve tablet hardness, reduce powdering, and improve appearance consistency.
Pharmaceutical Grade Quality: Meets mainstream pharmacopoeia standards, possessing high purity, strict impurity control, and good batch stability, making it suitable for pharmaceutical and high-requirement medical applications.
Tablet adhesive
As a highly efficient binder, it is widely used in wet and dry granulation processes, significantly improving tablet hardness and forming stability, and reducing tablet cracking and powdering.
Film Coating & Film Former
Used in pharmaceutical film coating systems, it produces uniform film with strong adhesion, helping to improve appearance, increase mechanical strength, and protect active ingredients.
Solubilizer & Stabilizer
Used as a solubilizer and stabilizer in liquid or semi-solid formulations, it helps improve the solubility of poorly soluble active ingredients and formulation stability.
Suspension & Topical Formulations
Suitable for oral suspensions, topical formulations, and topically administered products, acting as a thickener, stabilizer, and improve the feel of the tablet.
FAQ
Q: What are the core advantages of K90 compared to K30 and K60?
A: K90 has a higher molecular weight and greater viscosity, resulting in stronger adhesion and film-forming abilities. It can achieve better structural stability and mechanical strength at the same or lower addition levels.
Q: Does it meet the requirements of mainstream pharmacopoeias and export markets?
A: Pharmaceutical-grade Povidone K90 typically meets the standards of mainstream pharmacopoeias such as USP, EP, and ChP. Impurities and residues are strictly controlled, making it suitable for international pharmaceutical and export projects.
Q: Is it easy to operate during production?
A: It has good water solubility and strong dispersibility, high compatibility with common APIs and excipients, and a wide process window, which helps improve production stability and batch consistency.
Q: Is it suitable for long-term stable supply and large-scale procurement?
A: The product has good batch stability and mature quality control, making it suitable for continuous production and long-term, large-scale procurement by medium to large-sized pharmaceutical companies.
