Ethylene glycol may also be one of the minor ingredients in screen cleaning solutions, along with the main ingredient isopropyl alcohol. Ethylene glycol is commonly used as a preservative for biological specimens, especially in secondary schools during dissection as a safer alternative to formaldehyde. It is also used as part of the water-based ...
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
R' = H or alkyl C7 or less; or OR' consisting of carboxylic acid ester, sulfate, phosphate, nitrate, or sulfonate. Polymers are excluded from the glycol category, as well as surfactant alcohol ethoxylates (where R is an alkyl C8 or greater) and their derivatives, and ethylene glycol monobutyl ether (CAS 111-76-2).
Technical Guidance WM2: Hazardous Waste: Interpretation of the definition and classification of hazardous waste [1] is a guidance document developed and jointly published by the English Environment Agency, Natural Resources Wales, Scottish Environment Protection Agency and the Northern Ireland Environment Agency to provide guidance on the assessment and classification of hazardous waste based ...
The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a ...
One U.S. FAA-approved deicing fluid (Kilfrost DF Sustain) is 1,3-propanediol, a fermentation product of corn, as a freezing point depressant instead of ethylene glycol or propylene glycol. [ 19 ] Benzotriazole (and tolyltriazoles), although not highly toxic, is not readily degradable and has a limited sorption tendency.
[1] [2] As such, they serve the same purpose as the well-known R-phrases, which they are intended to replace. Hazard statements are one of the key elements for the labelling of containers under the GHS, along with: [3] an identification of the product; one or more hazard pictograms (where necessary)
