In addition to being an allergen, it is a formaldehyde releaser, since it generates formaldehyde slowly as it degrades. Although the formaldehyde acts as a bactericidal preservative, it is a known carcinogen. In 2005–06, it was the 14th-most-prevalent allergen in patch tests (3.7%). [4]
A 1988 Canadian study of houses with urea-formaldehyde foam insulation found that formaldehyde levels as low as 0.046 ppm were positively correlated with eye and nasal irritation. [72] A 2009 review of studies has shown a strong association between exposure to formaldehyde and the development of childhood asthma. [73]
To the average consumer, formaldehyde may be best known as an embalming agent. But this naturally occurring chemical is a major industrial staple, used in many consumer goods, including cleaning ...
The American Cancer Society states that although quaternium-15 releases formaldehyde, a known carcinogen in laboratory test animals at relatively high doses, because the amount of formaldehyde released from these products is low, it is unclear that avoiding quaternium-15 in cosmetics provides any health benefits.

IARC group 1 Carcinogens are substances, chemical mixtures, and exposure circumstances which have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC). [1] This category is used when there is sufficient evidence of carcinogenicity in humans.
Because, basically it tells us there are known carcinogens in our food supply,” said Muncke. Many plastics, including food packaging and other kitchenware, contain chemicals that leach into food.
Formaldehyde is a known carcinogen, for instance being associated with nasopharyngeal cancer and leukemia. [14] [20] [39] This compound also occurs in small amounts as a contaminant in alcoholic beverages, and is chemically similar to the carcinogenic ethanol (alcohol) metabolite acetaldehyde.
The trucks were carrying about 25,000 liters of pesticides and 76 tons of sulfuric acid, according to the National Agency for Water and Basic Sanitation, raising concerns about environmental damage.
