Ethoxylation is commonly practiced, albeit on a much smaller scale, in the biotechnology and pharmaceutical industries to increase water solubility and, in the case of pharmaceuticals, circulatory half-life of non-polar organic compounds.
Polysorbate 20 (common commercial brand names include Kolliphor PS 20, [2] Scattics, Alkest TW 20, Tween 20, and Kotilen-20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan monolaurate.
[32] [33] The ethoxylation process makes the cleansing agents, such as sodium laureth sulfate and ammonium laureth sulfate, less abrasive and offers enhanced foaming characteristics. 1,4-Dioxane is found in small amounts in some cosmetics, a yet unregulated substance used in cosmetics in both China and the U.S. [34] Research has found the ...
Narrow-range ethoxylates (NREs) in chemistry are fatty alcohol polyglycol ethers with a narrow homolog distribution and are known nonionic surfactants.They can be produced industrially, for example, by the addition of ethylene oxide onto fatty alcohols in the presence of suitable catalysts (layer compounds which have been calcined or hydrophobized with fatty acids).
Separately, studies show that exercise is linked to improved mental health, thanks to a process that unfolds during physical activity wherein your brain releases endorphins, a hormone that boosts ...
The dress code for the 2025 Met Gala has been announced, and this year menswear is taking center stage.. In conjunction with the upcoming exhibit at the Metropolitan Museum of Art's Costume ...
Ethylene oxide is widely used to generate detergents and surfactants by ethoxylation. Its hydrolysis affords ethylene glycol. It is also used for sterilisation of medical instruments and materials. The reaction of epoxides with amines is the basis for the formation of epoxy glues and structural materials.
We found the best technology for adults over 65 at CES this year. From AI aids to ‘aging in place’ smart home solutions, the annual tech show kept older users in mind.
