Lye is a hydroxide, either sodium hydroxide or potassium hydroxide. The word lye most accurately refers to sodium hydroxide (NaOH), [ citation needed ] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Otherwise, the lye itself will absorb water and actually create a mass itself, exacerbating the clog issue. [4] Liquid formulations of corrosive alkaline drain cleaners can contain sodium hypochlorite and lye (sodium hydroxide or potassium hydroxide) in concentrations up to 50 percent. Other corrosive mixtures come as two-part cleaners that are ...
Originally, it was simply a liquid lye (sodium hydroxide). In the late 1970s, the product was reformulated as a combination of liquid lye and sodium hypochlorite . Sodium hypochlorite is used in low (5%) concentration as laundry bleach and in higher concentrations as a swimming pool disinfectant.
Safety considerations are similar to those of sodium hydroxide. The caustic effects arise from being highly alkaline, but if potassium hydroxide is neutralised with a non-toxic acid then it becomes a non-toxic potassium salt. It is approved as a food additive under the code E525.

Ok, I see. The problem is the first scentence "Lye is a corrosive alkaline substance, specifically, sodium hydroxide ." Pokeman 17:19, 14 May 2008 (UTC) I feel the opening sentence is still ambiguous. Could it be rephrased "Lye is any corrosive alkaline substance"? Or "a lye is a member of a family of corrosive alkaline substances"?
A much older form of portable toilet chemical is lye. Lye was used during the old "wooden outhouse days" to prevent odors. After a person is done using the portable toilet they would sprinkle a bit of lye into the holding tank. [citation needed] Lye can be dangerously corrosive to skin, and is rarely used today.
