Dabur plays with public's lack of knowledge about v/v and w/w to inflate the perceived percentage of alcohol in its hand sanitizer [COMPACTIDEA]

Dabur knows that public doesn't know what v/v and w/w mean. So in Amazon's title, it cleverly says 70% v/v alcohol, making buyer feel like this product is more potent compared to those hand sanitizers which contain "only 60% alcohol", whereas on w/w basis, this Dabur product also contains only 60% alcohol. Clear deception.

Such nasty tricks go on in the open without bone-breaking fines!
