What it is

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

How it works

It works by binding to olfactory receptors in the nose, creating the perception of a fresh, citrusy scent. In the product, it simply contributes to the overall fragrance profile and has no functional skincare benefit.

Pros

Pleasant scent

Adds a fresh, citrusy aroma that can make your skincare routine feel more enjoyable and uplifting.

Low comedogenic risk

Unlikely to clog pores, so it generally won't contribute to breakouts for most skin types.

Cons and cautions

Potential irritant

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

No skincare benefit

This ingredient only provides scent—it does not hydrate, soothe, or improve skin health in any way.

Best for

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

Use caution if

  • Individuals with sensitive, reactive, or eczema-prone skin
  • Anyone with a known allergy to synthetic fragrances

Usage tips

If you have sensitive skin, patch test any product containing this ingredient on a small area before full use.
Consider fragrance-free alternatives if you experience irritation from scented products.

Safety summary

Generally considered safe at low concentrations for most people, but can be a skin sensitizer. Those with fragrance allergies or sensitive skin should approach with caution.

Research notes

Limited peer-reviewed research specifically on this compound, but it is part of a broader class of synthetic fragrance ingredients that are well-studied for skin sensitization potential.

Common label clues

Typical concentration
Typically used at very low concentrations (less than 1%) due to its strong scent and potential sensitization.
Regulatory status
Approved for use in cosmetics in the EU and US, but subject to concentration limits and labeling requirements as a fragrance allergen in some regions.
Common uses
Fragranced skincare, Perfumes, Body lotions, Cleansers
Environmental note
As a synthetic compound, its environmental persistence and bioaccumulation potential are not well-documented; natural alternatives may be more biodegradable.

Good to know

  • This ingredient is often listed simply as 'fragrance' or 'parfum' on labels, so it may not always appear by its full chemical name.
  • Regulatory bodies like the IFRA (International Fragrance Association) set usage limits to minimize irritation risk.
