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),

Ionic behavior assessment of surface-active compounds from corn steep liquor by exchange resins [PDF]
, 2016 Depending on their ionic nature, biosurfactants can be classified as nonionic, anionic, cationic, or amphoteric. The ionic behavior of biosurfactants is an important characteristic that dictates their use in industrial applications.
