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.

In formulas it is often supplied pre-dispersed in oils together with other polymers, which then appear separately on the list.

Functions

Viscosity controlling
Increasing or decreasing the viscosity (thickness) of cosmetics.
