Highest SCI % while maintaining clear formula
It’s my understanding that too much sodium cocoyl isethionate in a formula will cause it to become cloudy. I have successfully made a completely clear batch of shampoo with 5% SCI (as a co-surfactant) but I would like to increase this amount as much as possible. I am hoping you guys can spare me unnecessary test batches and tell me from your experience is there a certain % at which SCI will begin to diminish the clarity of a formula?
I know about it’s more water soluble cousin, sodium lauroyl methyl isethionate, but being a small time hobbyist I have been unable to source any of that.

@GeorgeBenson You could try adding an hydrotrope (eg. SXS), or adding a co-surfactant (like CAPB).

Adding onto ketchito, it will depend on the other ingredients in the formula- if you already have some hydrotropes/ other solubilizers your clarity could be impacted by those.
To limit test batches, don’t test this incrementally. You say you want as much SCI as possible, so try the upper end of what you are hoping for next (ex try 20%). If that fails, cut in half and try again, Still a bit tedious but better than just slowly edging up.
