	Cellulose acetate - Wikipedia, the free encyclopedia
		Cellulose acetate is used as a film base in photography, and as a component in some adhesives; it is also used as a synthetic fiber.
		Cellulose acetate (triacetate) photographic film was introduced in 1934 as a replacement for the unstable and highly flammable cellulose nitrate film stock that had previously been standard.
		Cellulose acetate or acetate rayon fiber (1924) is one of the earliest synthetic fibers and is based on cotton or tree pulp cellulose ("biopolymers").

	Acetate - Wikipedia, the free encyclopedia
		Acetate, or ethanoate, is the anion of a salt or ester of acetic acid.
		The acetate ion has the formula CH, and is the conjugate base of acetic acid.
		Acetate can also refer to cellulose acetate, especially fibers or other derived products such as the acetate disc used in audio record production.

	ATSDR - ToxFAQs™: Vinyl Acetate
		Vinyl acetate is an industrial chemical that is produced in large amounts in the United States.
		Vinyl acetate is also used as a coating in plastic films for food packaging and as a modifier of food starch.
		Vinyl acetate breaks down very quickly in the body to substances that are normally found in the body; thus, measurement of these break down products is not useful for determining whether you have been exposed to vinyl acetate.

	Isopropyl Acetate
		Containers of isopropyl acetate may explode in the heat of the fire and should be moved from the fire area if it is possible to do so safely.
		Before a worker is placed in a job with a potential for exposure to isopropyl acetate, a licensed health care professional should evaluate and document the worker's baseline health status with thorough medical, environmental, and occupational histories, a physical examination, and physiologic and laboratory tests appropriate for the anticipated occupational risks.
		Keep isopropyl acetate out of a confined space, such as a sewer, because of the possibility of an explosion, unless the sewer is designed to prevent the build-up of explosive concentrations.

	Cellulose Acetate
		Although cellulose acetate was first prepared in 1865 by the French chemist Paul Schützenberger, it was not until 1894 that the first industrial process for its manufacture was patented in the UK by Charles Cross and Edward Bevan.
		Cellulose acetate (CA) in combination with plasticizers, such as diethyl and dimethyl phthalate, produces a plastics material which can be heat softened and forced under pressure into a cool mould.
		Despite being much less flammable than cellulose nitrate, acetate film did not become established for photographic use until after World War II because of the technical excellence of celluloid and the vested interests of film manufacturers.

	Vinyl Acetate (Site not responding. Last check: 2007-11-07)
		Vinyl acetate is used in the production of a wide range of polymers, including polyvinyl acetate, polyvinyl alcohol, polyvinyl acetals, ethylene-vinyl acetate copolymers and polyvinyl chloride-vinyl acetate copolymers, which are widely used in the production of adhesives, paints and food packaging.
		Vinyl acetate is rapidly metabolized by esterases in human blood and animal tissues to acetaldehyde and acetic acid.
		Oral administration of vinyl acetate to rats during pregnancy did not result in maternal or developmental toxicity, whereas exposure by inhalation induced maternal toxicity, retarded embryonic growth and minor skeletal alterations at the highest dose tested.
