faster than HCl but odourless

Method: At 68 °C, 35 ml of Acid are added to 215 ml of a suspensionof CaCO3 (0,1 mol/l). The time until all of the CaCO3 is dissolved is measured.

Toxicity & Environmental Aspects

Methanesulfonic AcidToxicity & Environmental Aspects

MSA is readily biodegradable (OECD 301 A)- Carbonate and sulphate are formed as the

ultimate decompositon products

MSA is halogen-free and nitrogen-free

LD 50 (oral, rat): approx. 1000 mg/kg
