In plain English

This is a man-made chemical used to give products a pleasant floral or green smell. It doesn't moisturize, treat, or improve your skin—it's purely for fragrance. Because it's a fragrance ingredient, it can sometimes cause skin irritation or allergic reactions, especially if you have sensitive skin.

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 organic compound from the aldehyde family, specifically designed for use as a fragrance ingredient in cosmetics and personal care products.

How it works

It evaporates from the skin's surface, releasing a floral, green scent that masks the natural odor of other ingredients. It does not interact with the skin's biology or provide any functional skincare benefit.

Pros

Pleasant scent

Adds a floral, green fragrance that many people find appealing in skincare and beauty products.

Low comedogenic risk

Unlikely to clog pores, making it suitable for non-acneic skin types when used in low concentrations.

Cons and cautions

No skincare benefit

Provides only fragrance—no moisturizing, anti-aging, or protective effects for the skin.

Irritation potential

Can cause redness, itching, or stinging in people with sensitive skin or fragrance allergies, especially in leave-on products.

Best for

  • People who enjoy scented skincare and have no history of fragrance allergies
  • Those using products where scent is a priority

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 product containing this ingredient on a small area of skin before full use.
If you have sensitive skin, opt for fragrance-free versions of your favorite products.
Use scented products on the body rather than the face to reduce irritation risk.

Safety summary

Generally recognized as safe for most people at low concentrations, but carries a moderate risk of skin irritation and allergic reactions, particularly for those with sensitive skin or fragrance allergies.

Research notes

Limited direct research on this specific compound, but it belongs to a class of fragrance aldehydes known to be common allergens in patch test studies. Regulatory bodies like IFRA and the SCCS have reviewed its safety for cosmetic use.

Common label clues

Typical concentration
Very low, typically less than 0.1% in leave-on products
Regulatory status
Approved for use in cosmetics in the EU and US within IFRA safety guidelines, but must be listed as a fragrance allergen if present above certain thresholds in the EU.
Common uses
Fragranced skincare, Perfumes, Body lotions, Cleansers
Environmental note
As a synthetic compound, it may persist in water systems after washing off; however, its low concentration in products limits environmental impact.

Good to know

  • This ingredient is often listed simply as 'fragrance' or 'parfum' on labels, so it may not appear by name.
  • Regulatory bodies like the IFRA (International Fragrance Association) set safety limits for its use in cosmetics.
