Caution

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A formaldehyde-amine condensation product used in industrial applications, acting as a formaldehyde releaser with sensitisation potential.

This compound is a Mannich-base formaldehyde releaser, structurally similar to other cosmetic preservatives like DMDM hydantoin. It releases formaldehyde at room temperature and in solution. Formaldehyde releasers are restricted in the EU under Annex V (preservatives) or Annex III, and must be declared on the ingredient list. The 1:4 ratio of DIPA to formaldehyde suggests significant formaldehyde release potential.
