In plain English

This is a man-made chemical that smells nice—like a fresh, floral scent. It's added to products to make them smell good, but it doesn't help your skin in any way. Some people with very sensitive skin might find it irritating, though that's not common.

  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

What it is

A synthetic ester compound used primarily as a fragrance ingredient in cosmetics and personal care products. It is not derived from natural sources but is created in a lab to produce a specific scent profile.

How it works

It evaporates from the skin's surface, releasing molecules that interact with olfactory receptors in the nose, creating the perception of a fresh, floral scent. It has no functional role in skincare beyond fragrance.

Pros

Pleasant scent

Adds a fresh, floral fragrance that can make your skincare routine more enjoyable and uplifting.

Low irritation risk for most

At typical low concentrations, it rarely causes irritation in people without fragrance sensitivities.

Cons and cautions

No skincare benefit

This ingredient only adds scent—it doesn't moisturize, protect, or improve your skin in any way.

Potential allergen

Like many fragrance ingredients, it can trigger allergic reactions or irritation in people with sensitive skin or fragrance allergies.

Best for

  • People who enjoy scented skincare and have no history of fragrance sensitivity
  • Those looking for a fresh, floral scent in their products

Use caution if

  • Individuals with known fragrance allergies or sensitive, reactive skin

Usage tips

Patch test any new scented product on a small area of skin before full use.
If you have sensitive skin, opt for fragrance-free versions of your skincare products.

Safety summary

Generally recognized as safe for use in cosmetics at low concentrations, but it can be a skin sensitizer for a small percentage of people. Regulatory bodies like IFRA monitor its safe use.

Research notes

Limited peer-reviewed research specifically on this compound, but it is part of a well-studied class of fragrance esters. Safety assessments rely on industry data and patch testing.
