11. Toxological Information
Draize test, rabbit, skin: 50 mg/24H Severe
Oral, rat: LD50 = 273 mg/kg
CAS# 1310-58-3
Not listed by ACGIH, IARC, NIOSH, NTP, or OSHA
Not listed by ACGIH, IARC, NIOSH, NTP, or OSHA
Potassium Hydroxide Solution is a severe eye, mucus membrane, and skin irritant.
12. Ecological Information
Completely soluble in water
Will degrade by reaction with carbon dioxide from the atmosphere to produce a
non-hazardous product.
Information not available. No long
term effects expected due to degradation. The
preparation is already in dilute solution and adverse aquatic effects are not expected
