Effect of Surfactant HLB Value on Enzymatic Hydrolysis of Chitosan
ChemEngineering, 2022 Nonionic surfactants are reported as being able to enhance enzyme stability and increase the conversion of enzymatic reactions. Surfactant-assisted enzymatic hydrolysis conversion is affected by surfactant HLB values. This work investigated the influence

Interaction of nonionic surfactant AEO9 with ionic surfactants [PDF]
Journal of Zhejiang University-SCIENCE B, 2005 The interaction in two mixtures of a nonionic surfactant AEO9 (C12H25O(CH2CH2O)9H) and different ionic surfactants was investigated. The two mixtures were AEO9/sodium dodecyl sulfate (SDS) and AEO9/cetyltrimethylammonium bromide (CTAB) at molar fraction of AEO9, alpha(AEO9) The surface properties of the surfactants, critical micelle concentration (CMC),

A conductometric investigation of hydroxypropylmethyl cellulose/sodium dodecyl sulfate/nonionic surfactant systems [PDF]
Journal of the Serbian Chemical Society, 2014 Surfactant mixtures are very often used in various cosmetic and pharmaceutical products because they commonly act in synergism and provide more favorable properties than the single surfactants.

Toxicity of nonionic surfactants [PDF]
WIT Transactions on Ecology and the Environment, 2008 Nonionic surfactants are amphilic chemicals that enhance desorption and bioavailability by increasing solubility and dispersion of poorly soluble hydrocarbons and oils. This study was conducted to determine the toxicity of commercial nonionic surfactants by using the Microtox Acute Toxicity test which is a rapid, simple test for toxicity. The test uses

Studies on the Detergency of Nonionic Surfactant. V.
Journal of Japan Oil Chemists' Society, 1963 To investigate the detergency of nonionic surfactant, following two parts of experiments were carried out for the polyoxyethylene nonylphenyl ether EO 10mole (PEG-N) by using Launder-O-meter and artificial standard soiled cotton cloth.1) The effects of inorganic builders on soft and hard water.The concentration of PEG-N aqueous solutions was from 0.05g/
