Will cocamide MEA decrease micelle chare
In a simple cleansing formula with 7% SLS and 7% SLES active surfactants, will adding 2% cocamide MEA decrease micelle chare?

Increases micelle formation.

@chemicalmatt thank
What is the effect on micelle chare?

As @chemicalmatt mentioned, CDEA will increase micelle formation. This will reduce charge density of your micelles, but only because you’ll have CDEA molecules between SLES molecules (mixed micelles) and larger micelle structures compared to SLES alone. To reduce charge itself, you could either use a more ethoxylated SLES (inductive effect), a lower solution pH to protonate your anionic, electrolytes, and a co-surfactant or any other molecule that could form hydrogen bonds with your sulfate.
