I presume it means that it musn't be over 10% in total because they must have run tests for skin sensitivities over that saturation. The same for the Oakmoss at 0.1% maximum.
It is just straightforward measurements really.
100mls of liquid = no more than 10mls of methyl anthranilate fragrance
100mls of liquid = no more than 0.1ml of Oakmoss
Is that right?
