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.
Fragrance ingredients are often listed only as "parfum", so its presence in a perfume blend may not appear separately on the label.
