New formaldehyde base disinfectants.

Preparations of formaldehyde in various organic liquids-ethylene glycol, glycerol, and propylene glycol-serve as effective disinfectants towards microbial vegetative cells and spores. This disinfection is a temperature-dependent process and is manifest when these formaldehyde base disinfectants are dissolved in water. The irritating vapors associated with formaldehyde disinfection are not present in either of these new formaldehyde base disinfectants or in aqueous solutions of them.
