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).
Potassium hydroxide is used for industrial water treatment and is the precursor of potassium carbonate, several forms of potassium phosphate, many other potassic chemicals, and soap manufacturing. Potassium carbonate is used to produce animal feed supplements, cement , fire extinguishers , food products, photographic chemicals , and textiles.
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.
Preshave products and some shave creams contain potassium hydroxide to force open the hair cuticle and to act as a hygroscopic agent to attract and force water into the hair shaft, causing further damage to the hair. In this weakened state, the hair is more easily cut by a razor blade. Potassium hydroxide is used to identify some species of ...
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 ...
After the war, the Olins acquired the Mathieson Chemical Corporation—also founded in 1892. [7] [8] [9] Long before its association with Olin, Mathieson Alkali Works began business in Saltville, Virginia, and a year later acquired its neighbor, the Holston Salt and Plaster Corp. Saltville became a quintessential company town, where they produced chlorine and caustic soda, and in the process ...
To make hominy, field corn (maize) grain is dried, and then it is treated by soaking and cooking the mature (hard) grain in a dilute solution of lye (potassium hydroxide) (which can be produced from water and wood ash) or slaked lime (calcium hydroxide from limestone). The maize is then washed thoroughly to remove the bitter flavor of the lye ...
Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4.Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).
