Ingredient review
Terpinyl Propionate
INCI: TERPINYL PROPIONATE
Terpinyl Propionate is a synthetic fragrance ester that adds a pleasant floral-herbal scent to products, but it offers no skincare benefits and may cause sensitivity in those with fragrance allergies.
In plain English
Terpinyl Propionate is a man-made ingredient that smells nice—kind of like a mix of lavender and pine. It's added to lotions, creams, and cleansers just for its scent. It doesn't moisturize, treat acne, or help your skin in any active way. If you have sensitive skin or are allergic to fragrances, you might want to avoid products that list it.

What it is
Terpinyl Propionate is a synthetic ester created by combining terpineol (a naturally occurring alcohol found in pine oil) with propionic acid. It is a clear, colorless liquid with a sweet, floral-herbal aroma reminiscent of lavender and bergamot.
How it works
In a cosmetic product, Terpinyl Propionate functions solely as a fragrance ingredient. It evaporates from the skin's surface, releasing its scent molecules into the air. It does not interact with the skin's biology to provide any therapeutic or cosmetic benefit beyond the sensory experience of the fragrance.

Allergen potential
Can trigger allergic reactions or contact dermatitis in individuals sensitive to fragrance ingredients.

- Those without known fragrance allergies
