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 ketone compound used as a fragrance ingredient in cosmetics and personal care products. It is not a natural extract but is created in a lab to mimic or enhance certain scents.

How it works

It evaporates from the skin's surface, releasing scent molecules that your nose detects. It does not penetrate deeply or interact with skin cells in a meaningful way—its only role is to provide fragrance.

Pros

Pleasant scent

Provides a clean, floral, or fruity fragrance that many people enjoy in their daily skincare routine.

Low comedogenic risk

Unlikely to clog pores, so it's generally safe for acne-prone skin in terms of breakouts.

Cons and cautions

Potential irritant

As a synthetic fragrance, it can cause redness, itching, or stinging, especially on sensitive or compromised skin.

No skin benefit

It adds no moisturizing, anti-aging, or protective value—it's purely for sensory appeal.

Best for

  • People who enjoy scented skincare and have no history of fragrance allergies
  • Those using rinse-off products like body wash where exposure is brief

Use caution if

  • Anyone with sensitive, reactive, or eczema-prone skin
  • Those with known fragrance allergies or contact dermatitis

Usage tips

If you have sensitive skin, do a patch test on your inner arm before using a product containing this ingredient.
Consider fragrance-free alternatives if you notice any irritation or discomfort after use.

Safety summary

Generally recognized as safe for most people at low concentrations, but it is a known potential allergen and skin irritant. People with fragrance sensitivities should avoid it.

Research notes

Limited peer-reviewed studies specifically on this compound, but it is part of the broader category of synthetic fragrance ingredients that are monitored by IFRA and the EU CosIng database for allergenicity.

Common label clues

Typical concentration
Typically less than 1% in leave-on products
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions, subject to concentration limits set by fragrance safety organizations.

Perfumes, Fragranced skincare, Body lotions, Cleansers
Environmental note
As a synthetic compound, it may not biodegrade as readily as natural fragrances, but its environmental impact is not well-studied.

Good to know

  • This ingredient is often listed simply as 'fragrance' or 'parfum' on labels, so it can be hard to spot unless the full INCI is disclosed.
  • Regulatory bodies like the IFRA (International Fragrance Association) set safety limits for its use in cosmetics.
