    I have some questions about the so-called ‘tear-free’ formulations (baby shampoos and body washes). My main question is about the pH of these products. I once learned that is better to have a pH around 7, but why? Is only the low pH values that causes stinging in babies eyes? Harsh surfactants can also causes stinging? Is it really necessary to adjust the pH to ~7?
    Thanks in advance! 🙂
    Best regards,
