polyvinylpyrrolidone function
Polyvinylpyrrolidone (PVP) is a multifunctional polymer with many unique properties and uses. Here are the details:
In the cosmetics industry, PVP is widely used as an additive, moisturizer and thickener because of its extremely low toxicity and physiological inertia, and no irritation to the skin and eyes. For example, adding PVP to a mask can reduce the greasy feel and provide a soft and smooth feeling; PVP can also accelerate the penetration of mask ingredients, extend their retention time on the skin, in hair care products, PVP can form a transparent film, prevent hair moisture absorption, help shape, and reduce hair damage.
In the pharmaceutical industry, PVP is used as pharmaceutical excipients, drug carriers, sustained-release agents and drug synthesis intermediates to improve the taste, efficacy and stability of drugs, for example, PVP can be used to make adhesives, thickeners and stabilizers in oral liquids or tablets, and as a sustained-release agent for certain drugs.
In food processing, PVP is used as a clarifying agent and stabilizer for beer, juice, wine and other foods because of its non-carcinogenic, good food safety and complexation ability with specific polyphenols.
In detergents, PVP has anti-fouling reprecipitation properties, and can be used to prepare transparent liquid or heavy detergent to prevent the stimulation of synthetic detergent on the skin.
In the textile printing and dyeing industry, PVP has a good affinity with many organic dyes and can be used to improve dyeing power and hydrophilicity.
In the coatings and pigments industry, PVP coated coatings and coatings are transparent, do not affect the original color, can improve the gloss and dispersion of coatings and pigments.
In textile printing and dyeing, PVP has a good affinity with many organic dyes, and it can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials to improve dyeing power and hydrophilicity.
PVP is also used in polymer technology, agriculture, environmental protection and other fields.
