A good example of a mere puff is 'Daz makes whites whiter than white!!!' - it's just marketing nonsense with no legal implications.
Actually this is a true claim, at least to an extent. Historically the Daz brand has contained a lot of optical brightners which absorb light in the UV region of the spectrum and re-emit it in the blue part. This extra blue light gives fabrics the perception of being whiter than equivalent fabrics without the brightners.
