The measurements of surface tension, density and viscosity of aqueous solutions of n-octyl-β-d-glucopyranoside (OGP) and rhamnolipid (RL) were performed at constant concentration of OGP or RL. The measured values of the surface tension were compared to those calculated from the Joos equation as well as to the hypothetical one. The obtained results were analyzed with regard to adsorption at the water-air...
The contact angle measurements of the aqueous solutions of p-(1,1,3,3-tetramethylbutyl)phenoxypoly(ethylene glycol) (TX-100) and cetyltrimethylammonium bromide (CTAB) mixture with ethanol on nylon-6 were made in the range of the total concentration of CTAB and TX-100 mixture from 1 × 10−6 to 1 × 10−3 M and ethanol from 0 to 17.13 M. In the CTAB and TX-100 mixture the mole fraction of TX-100 was equal...
