Which of these surfactants blend would be theoretically milder to skin?

Which of these surfactants blends is theoretically milder for skin?

1. SLS/SLES/lauryl Glucoside 3/7/3% active surfactants

2. SLS/SLES/CAPB 3/7/3% active surfactants

see page 5

According to the super sketchy ex-vivo test in this ad, CAPB works better lowering irritation of anionic surfactant than APG.

But like I said, it’s super sketchy, and there are some obvious BS in this ad too, so don’t mind me. :#

@Abdullah I agree with @zetein. CAPB in the second blend, due to its charge, has more interaction with ionic groups in both SLS and SLES, helping reduce charge density more (thus, reducing irritation).

@zetein thanks. Very helpful chart

@ketchito thanks
What is charge density?
How to know which surfactant has how many charge density?
