(1) Sodium hydroxide, NaOH, also known as lye and caustic soda, is one of the most important of all industrial chemicals.(2) One member created an alternative cement for the concrete floor of our sauna, using fly ash (from coal burning plants, not waste dumps!), citric acid, lye , and borax.(3) Technically detergents are called u251cu00f6u251cu00e7u251cu2510Synthetic Detergentsu251cu00f6u251cu00e7u251cu00fb as they are not made from fats and lye from which soap is made.(4) Because soap is made primarily from a caustic blend of boiled animal fat, lye and soda, it is highly alkaline.(5) From the age of 15 or so, I would have my hair straightened with such hair-loving products as lye and perm solution.(6) In oven cleaners, lye and sodium hydroxide can burn skin, eyes, and the respiratory tract.(7) For example, sodium oxide dissolved in water yields sodium hydroxide, or lye .(8) Other household items carried by the stores on wheels included washing powder, liniments, salve, and lye used for making soap.(9) The catalyst is usually a base, either lye (which is NaOH) or potassium hydroxide.(10) Most conventional whitening toothpastes use sodium or potassium hydroxides, also known as lye , which is considered a poison by the Food and Drug Administration.(11) To make the Biodiesel, we heated the oil, then mixed in a measured solution of methanol and lye .(12) If more alkalinity was needed, then borax, sodium metaborate, sodium carbonate, or even lye were used.(13) When you mix ten parts oil with one part of methanol and a pinch of lye (the catalyst), the mixture settles out into about ten parts biodiesel and one part glycerine.(14) Make soap using lye (from hardwood ash) and animal fat.(15) Chemistry fans take note: lye is also called caustic soda and sodium hydroxide, but most people just call it lye .(16) It's important to avoid conventional oven cleaners; they contain lye and ammonia, which can damage your respiratory tract if inhaled.
