Does azelaic acid require special handling?

In pure powder form azelaic acid is a mild skin and eye irritant, so standard laboratory handling practices apply. According to the classification limits in its REACH registration dossier, finished products containing up to 15% by weight of azelaic acid are not classified as irritant. Azelaic acid has no CMR (carcinogenic, mutagenic or reprotoxic) properties. Always refer to the current safety data sheet for handling guidance.
