These are the CMC of SLS & SLES. It means this amount of surfactant will be free in surface between air & water and above that would form micceles. Now if we have both SLES and SLS in formula, will there be 356 mg/L total free surfactant or any other amount?
If 365 mg/L surfactant is free then when we have several surfactants, doesn't it make it more irritating to have a lot more free surfactants?
If it will have any different amount, how to determine and find that amount?
SLS 185 (mg/L)
SLES 171 (mg/L)
