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 stearic acid used commercially is often a mixture with palmitic acid, so the raw material is not a single compound.
Functions
- Surfactant – emulsifying
- Helping suspensions or dispersions of liquids in a second liquid by reducing the surface tension of the substances to be emulsified.
- Opacifying
- Reducing transparency or translucency of cosmetics.
