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

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.

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),

Nonionic polymer surfactants [PDF]
Journal of Polymer Science: Polymer Chemistry Edition, 1982 AbstractNonionic water‐soluble polymeric surfactants have been prepared by addition of long‐chain n‐alkyl epoxides to nonionic cellulose ethers. The polymers exhibit properties which can be explained by interchain association. The relationship between hydrocarbon‐modifier carbon number and the onset of association follows a linear relation analogous to

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
