A survey of formaldehyde in shampoos and skin creams on the Danish market.

To evaluate the exposure of the general population to formaldehyde from the use of cosmetic products, as well as to monitor whether cosmetic products comply with national regulations, 285 shampoos, creams, etc., were analysed for formaldehyde. Identification and determination of formaldehyde was performed by the EEC method for the analysis of formaldehyde in cosmetic products. It was shown that 29.5% of the products investigated contained 0.001%-0.147% total formaldehyde. In 10 of the products (3.5%), total formaldehyde content was > 0.05%. 8 of these products contained > 0.05% free formaldehyde. None of these products was labelled 'contains formaldehyde'. 17 of the products investigated were declared to contain specific formaldehyde-releasers. Formaldehyde could not be detected (detection limit 0.001%) in cosmetic products that were declared to contain Bronidox/Bronopol.
