What it is

A synthetic organic compound with a complex molecular structure, specifically a formate ester of a cyclopropane derivative, used primarily as a fragrance ingredient in cosmetics.

How it works

It works by binding to olfactory receptors in the nose to produce a scent. In a product, it simply adds a fragrance note; it does not have any active skincare function.

Pros

Low concentration needed

Only a tiny amount is required to achieve the desired scent, so overall exposure is minimal.

Cons and cautions

Potential irritant

Fragrance ingredients are a common cause of contact dermatitis, especially for those with sensitive skin.

Limited safety data

There is not a lot of publicly available research on this specific compound, making it harder to fully assess long-term safety.

Best for

  • People who enjoy scented products and have no history of fragrance allergy
  • Those using products where fragrance is a desired feature

Use caution if

  • Individuals with sensitive skin, eczema, or known fragrance allergies

Usage tips
