Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH2CH(OH)]n. It is used in papermaking, textiles, and a variety of coatings. It is white (colourless) and odorless. It is supplied as beads or as solutions in water.

Poly(vinyl alcohol) or Poly vinyl alcohol BP Ph Eur Grade Specifications
Ph Eur

Poly(vinyl alcohol) is obtained by polymerisation of vinyl acetate, followed by partial or almost complete hydrolysis of poly(vinyl acetate) in the presence of catalytic amounts of alkali or mineral acids.
Poly(vinyl alcohol) polymers comply with the following indices:
The mean relative molecular mass lies between 20 000 and 150 000. The viscosity is 3 to 70
mPa·s. The ester value which characterises the degree of hydrolysis is not greater than 280.

CHARACTERS
Appearance: Yellowish-white powder or translucent granules.
Solubility: Soluble in water, slightly soluble in ethanol, practically insoluble in acetone.
Various grades of poly(vinyl alcohol) are available. They differ in their degree of polymerisation and their degree of hydrolysis which determine the physical properties of the different grades. They are characterised by the viscosity and the ester value of the substance.

IDENTIFICATION
A. Infrared absorption spectrophotometry: To pass the test.
PreparationıDiscs; in some cases, the sample has to be milled, after cooling if necessary, before preparing the discs.
The spectrum obtained shows absorption maxima corresponding to poly(vinyl alcohol) at 2940 cm-1 and 2920 cm-1.
B. It complies with the test for viscosity (see Tests).

TESTS
Solution S: Heat on a water-bath 250 ml of water R in a borosilicate round-bottomed flask attached to a reflux condenser with stirrer, add 10.0 g of the substance to be examined and continue heating for 30 min with continuous stirring. Remove the flask from the water-bath and continue stirring until room temperature is reached.
Appearance of solution: Solution S is clear and not more intensely coloured than reference solution.
pH: 4.5 to 6.5 for solution S.
Viscosity: 85 per cent to 115 per cent of the value stated on the label.
Determine the viscosity using a falling ball viscometer immediately after preparation of solution S at 20 ± 0.1 °C.
Acid value: Maximum 3.0.
Ester value: 90 per cent to 110 per cent of the value stated on the label.
Heavy metals: Maximum 10 ppm.
Loss on drying: Maximum 5.0 per cent, determined on 1.000 g by drying in an oven at 105 °C for 3 h.
Sulphated ash: Maximum 1.0 per cent, determined on 1.0 g.

LABELLING
The label states:
the viscosity for a 40 g/l solution;
the ester value.

Emergency and First Aid Procedures:
Eyes - Flush with water for at least 15 minutes, raising and lowering eyelids occasionally. Get medical attention if irritation persists.
Skin - Thoroughly wash exposed area for at least 15 minutes. Remove contaminated clothing. Launder contaminated clothing before reuse. Get medical attention if irritation persists.
Ingestion - If Polyvinyl Alcohol is swallowed, if conscious, give plenty of water. Immediately call a physician. Never give anything by mouth to an unconscious person.
Inhalation - Remove to fresh air. Give oxygen if breathing is difficult; give artificial respiration if breathing has stopped. Get medical attention.

Extinguisher Media: Use media suitable to extinguish surrounding fire. Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
Flammable Limits in Air % by Volume: N/A
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Contain spilled material. Do not let the product enter drains. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow evacuating as per law.

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents, strong acids, and bases.

Respiratory Protection (Specify Type): None needed under normal conditions of use with adequate ventilation. NIOSH approved equipment should be worn if PELs are exceeded.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
