A corrosive alkaline salt used in drain cleaners and oven cleaners and responsible for their hazardous properties. Not particularly harmful to the environment if diluted or neutralized with an acid. Lye is used in the manufacture of soap, but in that process the lye reacts chemically and loses its hazardous properties.*corrisive. Eye, skin, and respiratory irritant. When highly concentrated as used in some drain openers and oven cleaners, it can burn eyes, skin, and internal organs. Can be fatal if swallowed. Used in a wide range of household cleaners.
a caustic, high pH by-product produced by the most common types of salt chlorine generators. Neutralized as part of the routine maintenance of the pH, presenting no handling hazards. Also known as lye or caustic soda.
chemical formula NaOH, sodium hydroxide was at one time used to develop positive photoresist but has fallen out of favor due to sodium contamination concerns. Sodium hydroxide is a strong base and is commonly sold as a 50% solution and has a density of 1.53Kg/L. Sodium hydroxide will burn skin or eyes.
caustic soda lye synthetic Sodium hydroxideâ€™s main use is in the formation of soap, when it is usually combined with palm oil or coconut oil. It is also a pH controller, helping to adjust the acid-base balance in products such as Elderflower Hand Softener.
A caustic alkali used in making hard soaps. It is now produced by processing salt water but was earlier obtained from the ashes of a particular kind of seaweed. (see How Is Soap Made? and The Chemistry of Soap) Used in Chandler's Soaps products.
NaOH, lye, caustic soda (Red Devil Drain Cleaner). A metallic base. Strongly alkaline and extremely corrosive. Mixing with fluids usually causes heat, and can create enough heat to ignite flammables (such as methanol), so add slowly. For biodiesel, this is one of the main reactants. Make sure you are purchasing "anhydrous sodium hydroxide." Anhydrous means it's dry, and water turns biodiesel into soap. Store this product in an airtight container to prevent NaOH from absorbing water and CO from the air. Store separately.
(also lye, caustic soda, white caustic, soda lye) Sodium hydroxide is derived from the electrolysis of brine sea water as a co-product of chlorine. It is a strong, caustic substance and causes severe corrosive damage to eyes, skin and mucous membranes, as well as the mouth, throat, esophagus and stomach. Injury can be immediate. Blindness is reported in animals exposed to as little as 2% dilution for just one minute. Skin is typically damaged by 0.12% dilutions for a period of one hour. Tests with healthy volunteers exposed to the chemical in spray from oven cleaners showed that respiratory tract irritation developed in 2 to 15 minutes. Sodium hydroxide is included as a toxic chemical on the EPA's Community Right-to-Know list. It is also a controlled substance in the workplace, and OSHA has set limitations on concentrations in the air. Found in: Conventional oven cleaners, drain cleaners
A strong alkaline compound used as a regenerant for anion exchange resin in deionization systems and for the pH modification of low pH (acid) water. Sodium hydroxide is also called caustic, caustic soda, or lye.
Sodium hydroxide (NaOH), also known as lye or caustic soda, is a caustic metallic base. An alkali, caustic soda is widely used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, and detergents. Worldwide production in 1998 was around 45 million tonnes.
