Mixed system of surfactants in shampoos
I’ve read that it’s better to use to a binary mixture of surfactants,for example SLES+SLS, than using SLES alone because of low irritant potential of the system.My question is that in what percentage should the two components be added. Is there any hard and fast rule that we need to follow, or we can add them in any percentages.Say if I am adding 15%(w/w) of SLES, is there a minimum amount of SLS i need to add for it to have a synergistic effect?

I don’t think that adding SLS to SLES would make your product less irritant… (quite the opposite I think). Add CAPB instead.

My own experience with those two is that SLES produced a poor quality of foam that improved by adding SLS, but I would never use SLS because of its irritant nature.

Kindly refer this topic and tell me if I missed out on something.

No, you didn’t miss anything. It merely says that SLS is highly irritant and that adding pretty much any other surfactant reduces the irritation. Better not to use irritating surfactants in the first place. As I have previously noted, there are some excellent blends of the ammonium salts available that have superb foam and are non-irritant.

Thank you for clearing my doubts.
