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.

The INCI name does not reveal the source of the alcohols used, and the alkyl chain lengths form a range rather than a single compound.
