Propyl Gallate

What Propyl Gallate is & what it does

An antioxidant used at low levels to protect oils and fats in a formula from going rancid. It extends shelf life and preserves quality.

What does Propyl Gallate do in skincare?

Propyl Gallate is used as an antioxidant and preservative-supporting ingredient. Its main job is to protect oils and other ingredients in the formula from going rancid through oxidation, which helps keep the product stable. It is added at low levels for this protective role rather than for a direct skin benefit.

Is Propyl Gallate safe?

Propyl Gallate is considered safe for use in cosmetics at the low concentrations typically used. It has been reviewed by cosmetic safety panels for this purpose. It is a known contact allergen for a small number of people, so those with sensitive skin or known allergies may prefer to avoid it or patch test.

Is Propyl Gallate natural or synthetic?

Propyl Gallate is synthetic as used in cosmetics. It is made by combining gallic acid (which occurs in plants) with propanol. The finished ingredient is produced through chemical synthesis rather than extracted directly from a plant.
