What it is

Heptadecadienyl Furan is a synthetic organic compound from the furan family, created in a lab to provide a specific scent note in cosmetic formulations.

How it works

In a cosmetic product, it acts solely as a fragrance ingredient, contributing to the overall scent profile. It does not provide any skincare benefits like moisturizing or anti-aging.

Pros

Unique scent profile

Provides a distinctive fragrance note that can enhance the overall sensory appeal of a cosmetic product.

Low typical concentration

Used in very small amounts, which reduces the likelihood of significant irritation for most users.

Cons and cautions

Limited safety research

There is minimal published research on this specific ingredient, making it harder to fully assess long-term safety.

Potential irritant

Furan derivatives can be skin sensitizers, and this ingredient may cause redness or itching in those with reactive skin.

Best for

  • People who enjoy scented products and do not have fragrance sensitivities
  • Those using products where the fragrance is well-tolerated

Use caution if

  • Individuals with known fragrance allergies or very sensitive skin
  • Anyone following a fragrance-free skincare routine

Usage tips

If you have sensitive skin, patch test any product containing this ingredient before full application.
Consider fragrance-free alternatives if you notice any irritation from scented products.

Safety summary

Heptadecadienyl Furan is considered safe for use in cosmetics at very low concentrations, but the lack of robust safety data and its potential as a skin sensitizer mean it should be used with caution, especially for those with fragrance sensitivities.

Research notes

There is very limited peer-reviewed research specifically on Heptadecadienyl Furan. Most safety assessments rely on general furan compound data and industry guidelines.

Common label clues

Typical concentration
Very low, typically less than 0.1%
Regulatory status

Common uses
Fragranced products, Perfumes, Scented lotions
Environmental note
As a synthetic compound, its environmental persistence and bioaccumulation potential are not well-documented, but furans in general can be of concern in aquatic ecosystems.
