CMC of mixed surfactants compared to one surfactant alone
According to Stepan, cmc of ALPHA-STEP® PC-48(Sodium methyl 2-sulfolaurate (and) Disodium
2-sulfolaurate) is 177 and CMC of LATHANOL® LAL Powder(Sodium lauryl sulfoacetate) is 131. But CMC of STEPAN-MILD® PCL( blend of Sodium methyl 2-sulfolaurate (and) Disodium2-sulfolaurate (and) Sodium lauryl sulfoacetate) is 65, that is a big decrease in CMC of mixture.My questions are1. If we combine two surfactants A+B, will CMC be equal to CMC of A+B or different?2. CMC of SLS is 185 and CMC of SLES is 171. If we use a 1:1 blend of SLS: SLES, will the CMC be 178 or anything else?3. Do you know what is the CMC of SLS: SLES blend, specially 1:1 blend?
