Score terms in plain English

Irritation risk

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic ester compound created in a lab, used exclusively as a fragrance ingredient in cosmetics and personal care products.

How it works

It evaporates from the skin's surface, releasing scent molecules that are detected by your nose. It has no active skincare function beyond providing fragrance.

Pros

Pleasant scent

Adds a light floral or fruity aroma that can make your skincare routine more enjoyable.

Low comedogenic risk

Unlikely to clog pores, so it's generally safe for acne-prone skin if you're not sensitive to fragrance.

Cons and cautions

Potential irritant

Can cause redness, itching, or stinging in people with sensitive skin or fragrance allergies.

No skincare benefit

Provides only scent—no moisturizing, anti-aging, or protective effects for your skin.

Best for

  • People who enjoy scented products and have no history of fragrance allergies
  • Those looking for a synthetic floral note in their routine

Use caution if

  • Individuals with sensitive, reactive, or eczema-prone skin
  • Anyone with a known fragrance allergy or contact dermatitis

Usage tips

Patch test any new scented product on your inner arm before applying it to your face.
If you notice irritation, switch to fragrance-free alternatives to see if symptoms improve.

Safety summary

Generally considered safe for most people at low concentrations, but it is a known skin sensitizer. Those with fragrance allergies or sensitive skin should avoid it.

Research notes

Studies show that synthetic fragrance ingredients like this one can cause allergic contact dermatitis in susceptible individuals. The EU Scientific Committee on Consumer Safety (SCCS) and IFRA provide safety guidelines for its use.
