Potassium Sorbate. \ CERTIFIED ORGANIC INGREDIENTS ●
TL;DR. This ingredient is a preservative used mainly to control yeast and mold in water-containing formulas. It is often paired with other preservatives because it is not a full broad-spectrum system on its own.
What does Potassium Sorbate. \ CERTIFIED ORGANIC INGREDIENTS do in a cosmetic formula?
This ingredient is a preservative used mainly to control yeast and mold in water-containing formulas. It is often paired with other preservatives because it is not a full broad-spectrum system on its own.
Is Potassium Sorbate. \ CERTIFIED ORGANIC INGREDIENTS clean?
