Priority Existing Chemical assessments

A priority existing chemical (PEC) is an industrial chemical that has been identified as requiring an assessment because there are reasonable grounds for believing that manufacturing, handling, storing, using or disposing of the chemical could be a risk to health and/or the environment.

Following a chemical assessment by NICNAS, there could be changes in circumstances that would later require particular aspects of a chemical to be re-assessed. This process is called secondary notification and assessment.

Most PEC assessments are accompanied by an easy-to-understand fact sheet which summarises key recommendations for a non-scientific audience.

Formaldehyde - PEC28 [WORD 5.4 MB]

CAS number(s): 50-00-0

Published 1 November 2006

Formaldehyde was declared a priority existing chemical for full assessment on 5 March 2002 (PEC/28) in response to occupational and public health concerns. Formaldehyde is mainly used for the manufacture of formaldehyde-based resins, which are widely used in a variety of industries, such as the wood industry. Formaldehyde is also used directly or in formulations in a number of industries including medicine-related industries (such as forensic/hospital mortuaries and pathology laboratories), embalming in funeral homes, film processing, textile treatments, leather tanning, and a wide range of personal care and consumer products.

For a summary of the assessment read the Formaldehyde fact sheet.
