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 show the molecular weight, which determines how viscous the material is.

Functions

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