A formaldehyde releaser, formaldehyde donor or formaldehyde-releasing preservative is a chemical compound that slowly releases formaldehyde. Formaldehyde-releasers are added to prevent microbial growth and extend shelf life.[1] The intent of these compounds is that they release formaldehyde at levels that suppress microbial growth but sufficiently low to not threaten humans. The use of these chemicals in cosmetics has elicited controversy.
