All modern vapor anesthetics are capable of carbon monoxide (CO) production as a result of interaction with desiccated strong base containing carbon dioxide absorbents. In desiccated absorbents, desflurane produces the highest concentrations of CO. Sevoflurane is known to produce the nephrotoxic compound A (CA) independently from water content of the carbon dioxide absorbent. The purpose of thi...

In order to improve the outdoor exposure performance of laminated bamboo, boric acid/borax and UV absorbents, including triazole (UV1130), nano–TiO2, nano–SiO2, were used modify waterborne polyurethane (WPU) coatings, respectively. The physical chemical properties coatings with without modification evaluated by adhesion strength, contact angle, wear, temperature-resistance experiments. antimild...

Alkyl derivatives of MEA are used in the production of surfactants, dyes, in the manufacture of drugs as a buffer substance and for the stabilization of emulsions, in the manufacture of herbicides, cosmetics, antihistamines, are also of practical interest [1]. It is widely known also as useful “acid” gases (H2S, CO2, SO2, etc.) as absorbents in the process of cleaning process for gases in oil r...

Itaconic acid, also known as methylene succinic is a colorless, crystalline substance that found in nature. Due to its two functional carboxylic acid forms and - unsaturated bond, it can be used variety of sectors (plastics, super-absorbents, biopolymers, anti-scaling agents, etc.). produced via thermally decarboxylating citric catalysing the condensation derivatives with formaldehyde, aconitic...

The Cosmetic Ingredient Review (CIR) Expert Panel (Panel) reviewed the safety of 6 simple carbonate salts which function as absorbents, bulking agents, opacifying agents, pH adjusters, buffering agents, abrasives, and oral care agents in cosmetic products. The Panel reviewed relevant data relating to the safety of these ingredients, and concluded that the simple carbonate salts are safe in the ...

Carbon monoxide can be formed when volatile anaesthetic agents such as desflurane and sevoflurane are used with anaesthetic breathing systems containing carbon dioxide absorbents. This review describes the possible chemical processes involved and summarises the experimental and clinical evidence for the generation of carbon monoxide. We emphasise the different conditions that were used in the e...
