In plain English

This is a man-made ingredient that adds a specific scent to your skincare or beauty products. It doesn't moisturize, clean, or treat your skin—it's purely for fragrance. Because it's a synthetic fragrance, it can sometimes cause skin irritation or allergic reactions, especially if you have sensitive skin or a fragrance allergy.

What it is

A synthetic organic compound from the oxirane family, used primarily as a fragrance ingredient in cosmetics and personal care products. It is not a natural extract but is designed to mimic or create a fresh, woody, or floral scent profile.

How it works

It works by releasing volatile molecules that interact with olfactory receptors in your nose, creating a perception of scent. In a product, it simply adds fragrance; it has no known active skincare function like moisturizing or exfoliating.

Pros

Enhances sensory experience

Adds a fresh, pleasant scent that can make your skincare routine more enjoyable and luxurious.

Stable and long-lasting

Synthetic fragrance compounds like this one are chemically stable, so the scent remains consistent throughout the product's shelf life.

Cons and cautions

Potential irritant

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

No skincare benefit

This ingredient does not hydrate, repair, or protect your skin—it only adds scent, so it's an unnecessary addition for those focused on skin health.

Best for

  • People who enjoy scented skincare and have no history of fragrance allergies
  • Those using products where fragrance is a key sensory experience

Use caution if

  • Individuals with sensitive skin, eczema, or known fragrance allergies
  • Anyone preferring fragrance-free or hypoallergenic products

Usage tips

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

Safety summary

Generally considered safe at low concentrations used in cosmetics, but can cause skin irritation or allergic reactions in sensitive individuals. Long-term safety data is limited, so caution is advised for those with fragrance sensitivities.

Research notes

Limited peer-reviewed studies specifically on this compound; safety assessments rely on general fragrance ingredient data and IFRA guidelines. More research is needed on its dermal absorption and long-term effects.

Common label clues

Typical concentration
Typically used at very low levels, often below 1% in leave-on products.
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions, with usage restrictions set by IFRA to ensure safety at low concentrations.
Common uses
Fragranced skincare, Perfumes, Body lotions, Cleansers
Environmental note
As a synthetic compound, its environmental persistence and biodegradability are not well-documented; natural fragrance alternatives may be more eco-friendly.

Good to know

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