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 number 21 refers to the average degree of ethoxylation, so the raw material is a mixture of molecules with different chain lengths.
