Graft polymer surfactants provide very good colloidal stability because of strong steric repulsions between adsorbed surfactant films. The elastic and adhesion properties of adsorbed hydrophobically modified inulin polymer surfactant (INUTEC NRA) hav

Film thickness and disjoining pressure in emulsion films formed between two oil droplets in aqueous solutions of two ABA poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) triblock copolymers of the Pluronic series, F108 and P104, we

Oil-in-water emulsion films stabilized by hydrophobically modified inulin polymeric surfactants with different degree of substitution, DS, of alkyl chains on the inulin backbone, were studied. Four different graft co-polymers with increasing DS were

The rheological behaviour of Na + -montmorillonite suspensions in the presence of non-ionic polymers has been systematically investigated. Two different series of non-ionic polymers were studied. The first consisted of ABA block copolymers of polyeth

Microemulsions formed with water, isopropyl myristate, PHS−PEO−PHS polymeric surfactant, and alkanediol have been investigated using small-angle X-ray scattering (SAXS) and conductivity at 25 °C. I...

The present experimental investigation relates the adsorption of non-ionic surfactants onto Na+-montmorillonite clay with the rheological behaviour of the concentrated clay suspensions. The non-ionic surfactants used were the commercially available n

Phase diagrams of the ternary system water/poly(12-hydroxystearic acid)−poly(ethylene oxide)−poly(12-hydroxystearic acid) (PHS−PEO−PHS)/isopropyl myristate and the quaternary system water/PHS−PEO−PHS/1,2-alkanediol/isopropyl myristate wer

Formation of O/W nano-emulsions has been studied in water/C12Ē4/oil systems by the phase inversion temperature emulsification method. Emulsification was carried out at the corresponding HLB (hydrophilic−lipophilic balance) temperature, and then th

The adsorption of polyvinyl alcohol and Synperonic NP8 (nonyl phenol ethoxylate with an average of eight ethylene oxide groups per molecule) on fumed silica has been studied at various pH values. This was followed by an investigation of the competiti

The viscoelastic properties of concentrated microlatex dispersions were investigated using oscillatory measurements. The latices were prepared by polymerisation of styrene-in-water microemulsions using UV and azobiisobutyronitrile initiator. The comp
