POLYVINYL ALCOHOL (PVA)

Description

Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer derived from polyvinyl acetate. It is known for its film-forming properties, biodegradability, and ability to form strong, flexible films. It is commonly used in products that require controlled release or film formation.

INCI :

• Polyvinyl Alcohol (often listed as PVA)

CAS Number:

• 9002-89-5

Applications:

Polyvinyl alcohol is used in a variety of industries, including:

• Cosmetics & Personal Care: As a film-forming agent, binder, emulsifier, and stabilizer. It is often found in products such as shampoos, conditioners, moisturizers, facial masks, and sunscreens.
• Pharmaceuticals: Used as a binder in tablet formulations and controlled-release drug delivery systems.
• Textiles: In textile coatings and finishing processes.
• Packaging: As a biodegradable alternative to plastics.
• Adhesives: Commonly used in water-based adhesives and glues.
• Paper Coatings: Used as a coating agent in paper and cardboard products.

Appearance:

•  white  powder

Usage Rate:

• In cosmetics, PVA is typically used at concentrations ranging from 1% to 10% depending on the specific application.
• In pharmaceutical or textile applications, concentrations can vary widely, from 1% to 20% or more, depending on the desired properties.

Origin:

• Polyvinyl alcohol is a synthetic polymer, and its origin lies in the chemical polymerization of vinyl acetate, which is then hydrolyzed (saponified) to produce polyvinyl alcohol.
