WebSep 26, 2014 · The surface tension measurements showed that the cocobetaine is surface active in all aqueous solutions and depends on the salts concentration. The results obtained, presented in Table 1 indicate that in the case of using water as the solvent, the surface concentration at the saturated interface Γ ∞ is higher in comparison to the solution ... WebRelease point (Rp) is the surface tension of a detergent solution when oily soil just separates from fibre surfaces. This technique for quantifying soil release is based on thermodynamic considerations which state that the work of adhesion (the quantity (γ F/O − γ F/D) must be overcome by the detergent for oily soil to separate from a solid surface). chunhyang full movie https://newlakestechnologies.com
