I understand, Mr. André, and I don't want to interrupt you, but you said earlier that those products haven't been scientifically assessed.
So do we know whether we can in fact substitute those products for products that might contain 0.5% traces of phosphates? Can we go ahead and state that those products contain no phosphates, that we can use them to replace the products that currently contain phosphates or products that would contain a 0.5% phosphate level?
