Occupational regulation removes aldehydes from high-level disinfection
Glutaraldehyde and ortho-phthalaldehyde remain clinically effective and are disappearing from hospitals regardless, because tightened occupational exposure limits and a history of staff sensitisation have made them a liability to keep. European and Australian regulators moved earliest, with Asian occupational authorities following. Peracetic acid and hydrogen peroxide formulations take the displaced volume at higher unit prices and with better material compatibility profiles. Aldehyde chemistry now covers about 11% of high-level disinfection volume, down from a position of clear dominance fifteen years ago. Occupational timetables, not clinical guidelines, decide when each market converts.
