What it is

A synthetic organic compound from the lactone family, created in a lab to produce a sweet, creamy, coconut-like aroma for use as a fragrance ingredient in cosmetics.

How it works

It works by evaporating from the skin or hair after application, releasing its scent molecules into the air. It does not provide any skincare benefit beyond fragrance.

Pros

Pleasant scent

Adds a sweet, creamy, coconut-like fragrance that many people find appealing in lotions, washes, and perfumes.

Low irritation for most

At typical low concentrations, it is generally non-irritating for the majority of users without fragrance sensitivities.

Cons and cautions

No skincare benefit

This ingredient only provides scent and does not moisturize, protect, or improve skin health in any way.

Potential allergen

As a synthetic fragrance, it can trigger allergic reactions or contact dermatitis in people with fragrance sensitivities, especially with repeated use.

Best for

  • People who enjoy scented products
  • Those without fragrance sensitivities

Use caution if

  • Individuals with known fragrance allergies or sensitive skin

Usage tips

If you have sensitive skin, patch test a scented product on a small area before full use.
Look for products labeled 'fragrance-free' if you want to avoid synthetic scents like this one.

Safety summary

Generally recognized as safe for use in cosmetics at low concentrations by regulatory bodies and industry panels. However, like many fragrance ingredients, it can cause allergic reactions in sensitive individuals. The risk is low for the general population.

Research notes

Research on this specific compound is limited, but it belongs to a class of lactones that are well-studied as fragrance allergens. The main concern is skin sensitization, which is managed by IFRA usage restrictions.

Common label clues

Typically used at very low levels, often below 1%
Regulatory status
Approved for use in cosmetics in the US and EU, subject to general fragrance safety regulations. The International Fragrance Association (IFRA) sets usage limits to minimize sensitization risk.

Environmental note
As a synthetic compound, it may not be biodegradable and could accumulate in the environment, though data is limited.

Good to know

  • Fragrance ingredients are often listed simply as 'fragrance' or 'parfum' on labels, so you may not see this specific name.
