Why This Score

✔Ambroxan (5.0%) provides a stable, well-studied woody base with an ISS safety score of 7.0/10 (Grade A), commonly used in fine fragrances.
✔Formaldehyde Cyclodecyl Ethyl Acetal (5.0%) is a fixative with an ISS Grade A rating and is widely established in fragrance formulation.
⚠Tetramethyl Acetyloctahydronaphthalenes comprise 15.0% of the formula—the highest concentration. While rated Grade A, prolonged skin contact or use on sensitive areas warrants a patch test first.

Scores are calculated by HumanSafe™ — an independent third-party platform — using peer-reviewed toxicology sources, regulatory databases, and HumanSafe's Mood Architecture™.

Frequently Asked Questions

Is Oud Immortel safe for daily use?+

Oud Immortel carries a PSS Grade B rating, indicating acceptable safety for most consumers. However, fragrances are typically used in moderation—a few spritzes daily on pulse points is standard practice. If you have reactive or very sensitive skin, perform a 24-hour patch test on the inner arm first to rule out irritation.

Are there any ingredients I should watch out for?+

The primary concern is Tetramethyl Acetyloctahydronaphthalenes, which makes up 15% of the formula. While safety-graded, individuals with fragrance sensitivity, asthma, or skin conditions should avoid direct application to broken skin and ensure good ventilation. Formaldehyde-releasing agents like Formaldehyde Cyclodecyl Ethyl Acetal are present but within established safe-use limits for eau de parfum formats.

What does a PSS of 6.1/10 (Grade B) mean?+

The PSS (Product Safety Score) evaluates overall fragrance safety based on ingredient profiles and concentrations. A Grade B score indicates the product is considered safe for intended use by the general population, but it is not in the highest safety tier. This is typical for eau de parfum products, which contain higher fragrance concentrate than lighter formats like eau de toilette.

The HumanSafe™ Difference

Most safety tools rate ingredients in isolation — one score regardless of concentration, context, or how the product is used. We assess at actual use concentration.
