Cellulose nanocrystals mimicking micron sized fibers to assess the deposition of latex particles on cotton
Evdokia K. Oikonomou, Konstantin Golemanov, Pierre-Emmanuel Dufils +4
We report the interactions of cationic latex particles synthesized by RAFT/MADIX-mediated emulsion polymerization with anionic cellulose nanocrystals (CNCs) and cotton fabrics. Lat…
Silicone incorporation into an esterquat based fabric softener in presence of guar polymers
Evdokia K. Oikonomou, Camille Grandisson, Konstantin Golemanov +2
Fabric softeners are widely used to make clothes soft and impart nice smell. Household conditioners are water-based formulations consisting of quaternary ammonium surfactants assem…
Origin of the extremely high elasticity of bulk emulsions, stabilized by Yucca Schidigera saponins
Sonya Tsibranska, Slavka Tcholakova, Konstantin Golemanov +4
We found experimentally that the elasticity of sunflower oil-in-water emulsions (SFO-in-W) stabilized by Yucca Schidigera Roezl saponin extract, is by more than 50 times higher as…
Role of interfacial elasticity for the rheological properties of saponin-stabilized emulsions
Sonya Tsibranska, Slavka Tcholakova, Konstantin Golemanov +3
Hypothesis Saponins are natural surfactants which can provide highly viscoelastic interfaces. This property can be used to quantify precisely the effect of interfacial dilatational…
Foamability of aqueous solutions: Role of surfactant type and concentration
B. Petkova, S. Tcholakova, M. Chenkova +4
In this paper we study the main surface characteristics which control the foamability of solutions of various surfactants. Experiments with anionic, cationic and nonionic surfactan…
Theoretical model of viscous friction inside steadily sheared foams and concentrated emulsions
S. Tcholakova, N. D. Denkov, K. Golemanov +2
In a recent letter (Denkov et al., Phys. Rev. Lett., vol. 100 (2008) p. 138301) we calculated theoretically the macroscopic viscous stress of steadily sheared foam/emulsion from th…
