Leather tanned with the use of aldehydes, such as Formaldehyde. Aldehydes react with the proteins in a hide to form insoluble, stable compounds that are resistant to putrefaction. The use of formaldehyde is a standard tanning method for washable skins from sheep or lamb. It produces a strong, white, pliable, leather that is resistant to water (Kuhn 1986).
