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 raw material is a mixture of hydrocarbons rather than a single compound, which is why more than one CAS number is listed.
Functions
- Solvent
- Dissolving other components of cosmetics. Solvents are usually liquids (aqueous and nonaqueous).
