  • Will amount of NACL to achieve maximum viscosity change when percentage of surfactant in formula cha

    10% SLES reaches its maximum viscosity when 5.5% NACL is added to system. Now does it mean if we have 5% or 15% SLES in formula, the maximum viscosity will still be achieved with 5.5% NACL or salt curve will change?

    The viscosity/salt relationship changes with surfactant composition

    @Perry you mean if a formula has only 10% SLES and another formula has only 5% SLES, salt response will be different between these two formulas?

    I mean that whenever you change any aspect of the composition of a surfactant system (e.g. concentration, surfactant type, etc), the viscosity response to salt addition will change.
