According to the National Institutes of Health, phenol is toxic and people who are hypersensitive to it could experience death or serious side effects at very low exposures. -. Phenol Red (PR) also known as phenol sulfonaphthalein is a pH indicator and frequently used in cell biological laboratories for determining kidney function, is toxic in nature. Robert van Lith, Guillermo A. Ameer, in Oxidative Stress and Biomaterials, 2016. Phenol reacts with red blood cells, causing their destruction, preventing the transfer of molecular oxygen to the brain cells. Less-toxic phenols, such as n -hexylresorcinol, have supplanted phenol itself in cough drops and other antiseptic applications. On contact with eye and skin, it causes irritation and if inhaled, it is harmful for respiratory tract and digestive system. Phenol-Formaldehyde on green roofs might be an environmental concern. Toxic Phenol Ingredient in Vaccines. Kacenauskaite L, Gabrielaitis D, Bærentsen N, Martinez KL, Vosch T, Laursen BW. Results indicated that the phenol red adsorbed and delivered into cells by CBs was responsible for the toxicity to Hela cells in the medium without serum. 2. Mineral wool is an excellent material for increased retention capacity and the resilience of extensive vegetated roofs. Nano Lett. See Phenol (solid). Phenol is considered to be corrosive to the skin and it is known to be a protoplasmic poison: i.e. Science. NIH The size-dependent cytotoxicity of CBs was found to closely correlate to adsorption of phenol red, cellular uptake of phenol red-CB complexes and the amount of phenol red delivered into the cells by CBs. This paper reports a comparative photo-catalytic degradation of phenol red in aqueous … Toxic properties of phenol are expressed as follows: After deformation of red blood cells resulting decay products cannot be filtered from … The use of phenol in vaccine preparations introduces a poisonous and caustic substance into the body. Phenol red is 3H-2,1-Benzoxathiole 1,1-dioxide in which both of the hydrogens at position 3 have been substituted by 4-hydroxyphenyl groups. Phenol evaporates more slowly than water, and a moderate … A pH indicator changing colour from yellow below pH 6.8 to bright pink above pH 8.2, it is commonly used as an indicator in cell cultures and in home swimming pool test kits.
