The early type of interior which was known as ' vac-formed ', was produced by stretching a thin sheet of acetate over a mould by means of a vacuum, and lasted for three years until being replaced by the crisper, more detailed injection-moulded type first seen in the Thames ' Airborne ' caravan ( 420 ) in February 1962.

The damage to the edge of this test acetate shows that the underlying material is aluminium, rather than the vinyl of a record sold at retail. An acetate disc, also known as a test acetate, ( a term from Jamaican reggae culture, now also applied to individually recorded discs of solid plastic ), lacquer ( a technically correct term preferred by engineers in the recording industry ), transcription disc ( a special recording intended for, or made from, a radio broadcast ) or instantaneous disc ( because it can be played immediately after recording without any further processing ), is a type of gramophone record, a mechanical sound storage medium, widely used from the 1930s to the late 1950s for recording and broadcast purposes and still in limited use today.

The instrumental track for " The Surfer Moon " ( Brian's first known use of strings ) was recorded ( as " The Summer Moon ") in early May for an extra-BB act he was recording, Bob & Vikki, but this version was never released, although an acetate exists.

Since GISP2 ( 1990 – 1993 ) the US Polar Program has utilized a single-component fluid system, n-butyl acetate, but the toxicology, flammability, aggressive solvent nature, and longterm liabilities of n-butyl acetate raises serious questions about its continued application.

Traditionally the plate was copper, but now acetate, zinc, or plexiglas are also commonly used.

As it was intended for amateur use, 16 mm film was one of the first formats to use acetate safety film as a film base, and Kodak never manufactured nitrate film for the format due to the high flammability of the nitrate base.

Zinc acetate therapy initially made its appearance in the Netherlands, where physicians Schouwink and Hoogenraad used it in 1961 and in the 1970s, respectively, but it was further developed later by Brewer and colleagues at the University of Michigan.

Commercial production started in 1891, but the result was flammable and more expensive than acetate or cuprammonium rayon.

The biodegradability of fibers in soil burial and sewage sludge was evaluated by Korean researchers who found that biodegradability decreased in the following order: rayon, cotton, acetate ( meaning rayon decays more readily than cotton ).

The first popular Beatles bootleg was Kum Back, available around September 1969 in a plain white sleeve with no mention of a record company ; the vinyl bootleg was based on an acetate of one of the early rough mixes by Glyn Johns of the Get Back album ( which would later become Let It Be ).

Intraperitoneal injection of sodium acetate ( 20 or 60 mg per kg body mass ) was found to induce headache in sensitized rats, and it has been proposed that acetate resulting from oxidation of ethanol is a major factor in causing hangovers.

Increased serum acetate levels lead to accumulation of adenosine in many tissues including the brain, and administration of the adenosine receptor antagonist caffeine to rats after ethanol was found to decrease nociceptive behavior.
