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 numbers 38 and 8 are averages, so the raw material is a mixture of polymer chains of different sizes.
Functions
- Solvent
- Dissolving other components of cosmetics. Solvents are usually liquids (aqueous and nonaqueous).
