Also known as Allura Red AC, Red Dye No. 40 is often combined with aluminum to create Red 40 Lake, a non-water-soluble form ideal for products like chewing gum. Is Red Dye 40 safe?
Allura Red AC, also known as FD&C Red 40 or E129, is a red azo dye commonly used in food. It was developed in 1971 by the Allied Chemical Corporation, who gave the substance its name. [1] [2] It is usually supplied as its red sodium salt but can also be used as the calcium and potassium salts. These salts are soluble in water.
Red dye 40, also known as Allura Red, is a different chemical than red dye 3. It was first registered with the FDA in the 1970s and, like red dye 3, it’s synthesized from petroleum.
AC power plugs are also commonly circular, for example, Schuko plugs and IEC 60309. NMEA 2000 cabling using M12 connectors The M12 connector , specified in IEC 61076-2-101, is a circular electrical plug/receptacle pair with 12mm OD mating threads, used in NMEA 2000 , DeviceNet , IO-Link , some kinds of Industrial Ethernet , etc. [ 16 ] [ 17 ]
The splice of the copper pigtail to the existing aluminum wire can be accomplished with special crimp connectors, special miniature lug-type connectors, or approved twist-on connectors (with special installation procedures). Pig-tailing generally saves time and money, and is possible as long as the wiring itself is not damaged.
Ponceau 4R is a strawberry red azo dye which can be used in a variety of food products, and is usually synthesized from aromatic hydrocarbons; it is stable to light, heat, and acid but fades in the presence of ascorbic acid. [1]: 460
Sodium bis(2-methoxyethoxy)aluminium hydride (SMEAH; [1] trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis.
Due to the concentrations of fluorides and cyanides in spent potlining, and the tendency to leach in contact with water, the US Environmental Protection Agency (USEPA) listed the materials on 13 September 1988 (53 Fed.
