Nonylphenols are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail. Nonylphenols can come in numerous structures, all of which may be considered alkylphenols . They are used in manufacturing antioxidants , lubricating oil additives, laundry and dish detergents , emulsifiers , and solubilizers . [ 2 ]
A methylene blue active substances assay, or MBAS assay, is a colorimetric analysis test method that uses methylene blue to detect the presence of anionic surfactants (such as a detergent or foaming agent) in a sample of water. An anionic surfactant detected by the color reaction is called a methylene blue active substance (MBAS). [1]
Alkylphenols are xenoestrogens. [3] Long chain Alkylphenols have the most potent estrogenic activity. [3] The European Union has implemented sales and use restrictions on certain applications in which nonylphenols are used because of their alleged "toxicity, persistence, and the liability to bioaccumulate" but the United States EPA has taken a slower approach to make sure that action is based ...
The related nonylphenols with branched nonyl groups are commercially important detergents. It is used with mixed-metals stabilizers for heat stabilization of plastic and is a starting material for producing phenol resins. It's insoluble in water, but soluble in organic compounds like benzene and heptane. [1]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
"Usually, you can treat food poisoning at home by replacing the fluids lost via vomiting or diarrhea by drinking water, diluted juice, clear broths, sports drinks with electrolytes for adults and ...
