Methylene glycol (CAS no 463-57-0; EC no 207-339-5) or hydrated formaldehyde, is formed upon dissolution of formaldehyde in water and exists in equilibrium with formaldehyde in aqueous solutions.

Ireland sent information on the use of methylene glycol in hair straightening products to the Commission. This use was considered as unsafe due to the release of formaldehyde during normal and foreseeable use conditions of such products. By RAPEX several Member States notified the presence of the same or similar products on their markets.

The Irish Authorities analysed 21 products using the testing method for the determination of free formaldehyde according to Commission Directive 90/207/EEC (5. Determination in the presence of formaldehyde donors), and determined the following formaldehyde contents:
• 7 products had a content < 0.04% of formaldehyde
• 2 products had content from 0.1% to 0.9% of formaldehyde
• 10 products had content from 1.6% to 2.8%
• 2 products …
