Is SLS milder than SLES? 

"Sodium lauryl sulfate (SLS) is a classic anionic surfactant that is considered milder than sodium laureth sulfate (SLES) but has very similar properties".

    @ 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.

    @Perry @singhc10 thanks 
    I should be careful with information on internet.
