Is SLS milder than SLES?
Is SLS milder than SLES?

@ its other way, SLES is milder than SLS
Ethoxylation causes following:- Reduce irritancy(milder to skin)
- Decreases salt viscosity response(need more salt to thicken SLES than SLS)
- Reduces foaming

Yes, the opposite is true. SLES is theoretically more mild than SLS. Although you can make a mild formula with either.
But it does demonstrate that not everything you read on the Internet is true.
