	Chromogenic solution for immunoassay - Patent 4824784
		The N-N diethylhydroxylamine retards degradation of the solution of the chromogen in solvent and is particularly effective in retarding discoloration of a chromogen-solvent solution placed in storage over an extended period of time.
		Diethylhydroxylamine was added to the TMB/solvent solution to a concentration of 1 part by volume N,N-diethylhydroxylamine to 100,000 parts by volume of the TMB/solvent solution.
		A clear colorless or faintly tan solution resulted which could be stored for at least 1 year at 4 to 25 C, in a brown bottle without affecting its usefulness in an enzyme immunoassay.

	Reusing water bottles - Wikipedia, the free encyclopedia
		In 2003, a chain email was widely circulated making claims about the leaching of chemicals from plastic bottles from repeated washing, rinsing or heating.
		The email mentioned the chemical DEHA, which is also known as di(2-ethylhexyl) adipate, however the email incorrectly named it diethylhydroxylamine.
		When asked by Choice magazine, both the Australasian Bottled Water Institute and Australian Soft Drinks Association say DEHA isn't used in PET bottles in Australia, nor is diethylhydroxylamine.

		The Rejection Under 35 U.S.C. The rejection under 35 U.S.C. 103 is based upon the examiner's determination that the Abstract discloses unit dosages of diethylhydroxylamine in water for the treatment of cancer in mice, which unit dosages correspond to the unit dosages encompassed by the rejected claims.
		Assuming, arguendo, the increased longevity was due directly or indirectly to the administration of diethylhydroxylamine, there is insufficient evidence upon which to conclude that the increased longevity resulted from a retardation of the aging process caused by diethylhydroxylamine.
		Appellant has not advanced any cogent reasoning or proffered evidence to support the conclusion that the results obtained with mice can reasonably be extrapolated to the other animals encompassed by the appealed claims, such as cattle, or to the other compounds encompassed by claims 1 through 5, 7, 8, 10 through 17 and 19.

		Diethylhydroxylamine (DEHA) has been utilized as an oxygen scavenger in boiler systems in many industries for the past 20 years.
		However, sodium sulfite contributes solids to the boiler water and hydrazine was found to be toxic.
		These factors led to the introduction of alternative oxygen scavengers including diethylhydroxylamine (DEHA).

		Karen Chiarelli, a secretary in the health center, was unaware of these findings, "I wash my bottle in the dishwasher," she said.
		One of the toxins that frequently appeared in water samples from the reused water bottles was DEHA (diethylhydroxylamine), a carcinogen regulated in drinking water because it has been found to cause weight loss, liver problems, or possible reproductive difficulties.
		Von Braun said she was surprised to discover how widespread the reuse was and how long some people would hold on to a single bottle.

		The FSAI has received a number of queries about statements which indicate that the plastic used to manufacture drinks bottles (a material called polyethylene terephthalate or PET) contains a potentially carcinogenic cancer-causing element, diethylhydroxylamine or DEHA.
		It has also been stated that repeated rinsing and reuse of such bottles can cause the plastic to break down, resulting in release of the DEHA into the liquid contained in the bottle.
		Diethylhydroxylamine is not used as a plastics additive and it appears that there is confusion between this chemical and a chemical called diethylhexyl adipate, also abbreviated to DEHA.
