Breif Introduction Of PVP K12
PVP K12 is a powder with CAS 9003-39-8, odorless or slightly characteristic odor. It is easily soluble in water, alcohol, amines and halogenated hydrocarbons, but insoluble in acetone, ether, etc. It has excellent solubility, biocompatibility, physiological inertness, film-forming properties.
PVP K12, as a low value in PVPK series, has many properties.
Solubility: Rapidly dissolves in water and organic solvents, with clear and transparent solutions.
Adhesive property: Weak adhesive force, suitable for scenarios requiring low viscosity.
Film-forming property:Forms extremely thin and flexible transparent films.
Safety: physiologically inert, low-toxic, and non-irritating to the skin/mucous membranes.
Compatibility: coexists stably with most inorganic/organic compounds.
Stability: Good heat resistance and acid and alkali resistance.
Due to its small molecular weight, excellent water solubility, mild film-forming property and good biocompatibility, the application of K12 is mainly concentrated in scenarios where “low viscosity and high permeability” are required:
Pharmaceuticals and medical devices
As a binder for tablets/granules: Due to its small molecular weight, it can reduce the viscosity of the material and is suitable for preparing easily disintegrating preparations.
Combined with iodine to form povidone-iodine (PVP-I) : The low molecular weight characteristic of K12 can enhance the dispersibility of iodine and is used for skin and mucous membrane disinfection (such as wound wash, oral mouthwash).
As a drug carrier: assists in the dissolution of small molecule drugs and enhances bioavailability.
Cosmetics and personal care
For water-based solutions, essences, masks and other products: Adjust viscosity (low molecular weight makes it less likely to thicken), enhance skin moisture retention, and form a light and thin film that is not tight.
Contact lens care solution: As a lubricant, it reduces the friction between the lenses and the cornea, enhancing the wearing comfort.
Ceramic processing: As a low-temperature adhesive, it assists in the shaping of ceramic powder and is easy to decompose without residue during high-temperature firing.
Coatings and inks: As a dispersant, it helps pigments disperse evenly and improves the stability of the system;
Textile industry: Used for fiber processing to enhance antistatic properties and hand feel.
Other fields
Food industry: As a clarifying agent (such as in beer and juice filtration) or stabilizer, it improves the texture of products;
PVP K12, with its low molecular weight, high dissolution rate and weak adhesiveness , is irreplaceable in fast-release drugs, light cosmetic formulations and precision industrial processing. When making a selection, the model should be precisely matched based on the viscosity requirements of the application scenario, dissolution speed and regulatory requirements.
