Polyethylene glycol–polyvinyl alcohol (PEG-PVA) brand name Kollicoat IR is a multifunctional excipient [1] used as a pill binder as well as a wet binder. A typical formulation is composed of 25% polyethylene glycol (PEG) and 75% polyvinyl alcohol (PVA); where the vinyl alcohol moieties are grafted on a polyethylene glycol backbone.
Ethylene vinyl alcohol (EVOH) is a formal copolymer of ethylene and vinyl alcohol. Because the latter monomer mainly exists as its tautomer acetaldehyde , the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis.
The Ziegler alcohol synthesis involves oligomerization of ethylene using triethylaluminium followed by oxidation. [2] The triethylaluminium is produced by action of aluminium, ethylene, and hydrogen gas. In the production process, two-thirds of the triethylaluminium produced is recycled back into the reactor, and only one-third is used to ...
Triton X-100 is a commonly used detergent in laboratories. [5] Triton X-100 is widely used to lyse cells to extract protein or organelles, or to permeabilize the membranes of living cells. [6] Some applications include: Inactivation of lipid-enveloped viruses (e.g. HIV, HBV, HCV) in manufacturing of biopharmaceuticals; Industrial purpose ...
3. Polar columns (like DB-WAX or HP-FFAP): These are polyethylene glycol (PEG) columns. They are more suited for polar compounds, but Lauryl Alcohol Ethoxylates may still need derivatization. The DB-5 or HP-5 column is often preferred for surfactants like ethoxylates due to its moderate polarity, providing good separation of ethoxylation products.
Also used in cosmetics and skin care products. Azodicarbonamide – flour bleaching agent. Also used in the production of foamed plastics and the manufacture of gaskets. Banned as a food additive in Australia and Europe. Azorubine – color (red) (FDA: Ext D&C Red #10)
Potentially Hazardous Food has been redefined by the US Food and Drug Administration in the 2013 FDA Food Code to Time/Temperature Control for Safety Food. [1] Pages 22 and 23 (pdf pages 54 and 55), state the following: PHF table A 2013 FDA Food Code. PHF table B 2013 FDA Food Code.
Polyethylene is a very common polymer used in many everyday plastic products, such as water bottles, grocery bags, and drain pipes. However, its high molecular weight hinders the ability for microorganisms to naturally degrade the material.
