Linalyl Phenylacetate
INCI: LINALYL PHENYLACETATE
A synthetic fragrance ester that adds a sweet, floral scent but offers no direct skin benefit.
In plain English
Linalyl Phenylacetate is a man-made ingredient used to give cosmetics a pleasant, sweet, floral aroma. It doesn't moisturize, protect, or treat the skin—it's purely there for the scent. While generally considered safe at the low levels used in cosmetics, it can be a potential allergen for people with sensitive skin or fragrance allergies.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
Linalyl Phenylacetate is a synthetic ester created by combining linalool (a naturally occurring terpene alcohol found in many flowers and spices) with phenylacetic acid. It is a colorless to pale yellow liquid with a sweet, floral, honey-like odor.
How it works
In a cosmetic product, Linalyl Phenylacetate acts solely as a fragrance ingredient. It evaporates from the skin or hair, releasing its scent molecules into the air. It does not have any known function in altering the texture, stability, or efficacy of the product beyond providing a pleasant smell.
Pros
Pleasant Scent
Adds a sweet, floral, honey-like aroma that many people find appealing, enhancing the overall user experience.
Low Irritation for Most
At typical usage levels, it has a low irritation risk for the general population, making it a common choice for scented products.
Cons and cautions
No Skincare Benefit
This ingredient does not hydrate, soothe, or protect the skin. Its only role is to provide fragrance, so it adds no functional value to a skincare formula.
Potential Allergen
Like many fragrance ingredients, it can cause allergic contact dermatitis in sensitive individuals, leading to redness, itching, or irritation.
Best for
- People who enjoy scented cosmetics and do not have fragrance sensitivities
- Those looking for a sweet, floral scent profile in their products
Use caution if
- Individuals with known fragrance allergies or very sensitive skin
- Anyone following a fragrance-free skincare routine
Usage tips
