I recall Nurofen being fined by ACCC for making misleading claims on their product range. The fine was increased to $6M after an appeal was upheld.
As part of Colgate's Optic White range, there are three products that seem to have the exact same ingredients:
Optic White Stain-Less White
Optic White Express White
Optic White High Impact White
With regards to the Nurofen case, do you think there is a similar situation here with Colgate?
Similar? Maybe. But misrep cases are notoriously fact specific. In this case for example, I don't see Colgate as making specific claims about each product being better than the others in any specific role, unlike in the Nurofen case.
