What Is Sodium Hydroxide?
Sodium Hydroxide (NaOH) is white and odorless solid. It is a common ingredient in cleaning supplies, and perhaps most notably appears in drain and oven cleaning chemicals. Sodium hydroxide causes skin to burn upon contact and will cause irrevocable damage if ingested. (See our safety sheet on Sodium Hydroxide.) However, sodium hydroxide is FDA approved and is “generally recognized as safe” (GRAS). Used across a multitude of industries, some applications of sodium hydroxide include textiles, soap and cleaning products, paper, aluminum processing, petroleum, and bleach production.
