Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
Wash bottles may be filled with a range of common laboratory solvents and reagents, according to the work to be undertaken. These include deionized water, detergent solutions and rinse solvents such as acetone, isopropanol or ethanol. In biological labs it is common to keep sodium hypochlorite solution in a wash bottle to disinfect unneeded ...
Although the original process involves water, a green solvent itself, sc-CO 2 allows less waste materials. [57] In deep eutectic solvents, observations report that the higher the solvent's hydrophobicity, the higher the extraction efficiency of neonicotinoids from aqueous solutions, although the exact trend has not been established yet.

Braskem is the world leader in the production of biopolymer, with the Green Polyethylene "I'm green™", a thermoplastic resin produced from ethylene made from sugarcane ethanol, a 100% renewable raw material which helps reduce greenhouse gas emissions. The production started in 2010 and is located in Triunfo, South of Brazil.
After a long period in storage, the dense paint pigment and filler settles out over time and it can lose some of its solvent due to evaporation, becoming so thick and viscous that it does not flow properly when used. By the addition of more solvent, it can be diluted or re-dissolved to restore the paint to an appropriate consistency for use.
The most pervasive is the application of non-toxic cosolvents with water to produce formulations that can dissolve hydrophobic molecules while maintaining cohesion with biological systems. Common cosolvents for this purpose are ethanol, propylene glycol, glycerine, glycofural, and polyethylene glycols. [7]
