Limits of interpretation

The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.

See the EU regulation section for the applicable limits and conditions. The label does not show the concentration, and the protection of a product depends on the whole formula.
