What is excipient?

An excipient is a substance formulated alongside the active ingredient of a medication, included for the purpose of long-term stabilization, bulking up solid formulations that contain potent active ingredients in small amounts, or to confer a therapeutic enhancement on the active ingredient in the final dosage form, such as facilitating drug absorption, reducing viscosity, or enhancing solubility.

Physical properties:

Solubility

Easily soluble in water and solvents containing halogenated hydrocarbons, alcohols, amines, nitroalkanes and low molecular fatty acids, etc., but insoluble in a few solvents such as acetone, ether, turpentine, aliphatic hydrocarbons and alicyclic hydrocarbons. Compatible with most inorganic salts and various resins.

Crosslinked homopolymer of pure vinylpyrrolidone. It has the ability of polyvinylpyrrolidone (PVP) to complex with a variety of substances (such as various glutinous substances that cause the discoloration of beverages such as wine). And because of its insolubility, it is easy to remove after filtration.

Application:

1.Textile dyeing and finishing industry

PVP has a strong affinity with many organic dyes, mainly because the amide structure in the PVP molecule is combined with organic functional groups such as hydroxyl and amino groups in the dye. It can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon, and fibrous materials to greatly improve their dyeing strength and hydrophilicity. PVP can also be used as an anti-staining agent for fabrics, a stripping agent, a fast reducing agent for dyes, and a buffer and dispersing agent for pigments. After the graft copolymerization of PVP and nylon, the fabrics produced have improved wet wrinkle resistance and moisture resistance, and in the presence of PVP, most dyes become easily soluble in water, which increases the dyeing ability of dyes and makes dyeing and finishing. The fibers are bright and long-lasting.
