Potassium Hydroxide Solution
Synonyms: Caustic Potash; Lye; Potassium Hydrate
Chemical Name: Potassium Hydroxide (KOH)
Potassium Hydroxide is an odorless, white or slightly yellow, flakey or lumpy solid which is often in a water solution. It is used in making soap, as an electrolyte in alkaline batteries and in electroplating, lithography, and paint and varnish removers. Liquid contain 45 to 49% of Potassium Hydroxide
CAS Number: 1310-58-3
RTK Substance Number: 1571
DOT Number: UN 1813
Potassium Hydroxide can affect you when inhaled and by passing through the skin.
Potassium Hydroxide is a HIGHLY CORROSIVE CHEMICAL and contact can severely irritate and burn the skin and eyes leading to eye damage.
Contact can irritate the nose and throat.
Inhaling Potassium Hydroxide can irritate the lungs. Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency.
Exposure to Potassium Hydroxide can cause headache, dizziness, nausea and vomiting.
Potassium Hydroxide may cause a skin allergy.
