Why This Score

✔AMBROXAN and ACETYLCEDRENE are well-established fragrance ingredients with strong safety profiles (ISS 7.0/10 grade A), commonly used in fine fragrances.
✔TETRAMETHYL ACETYLOCTAHYDRONAPHTHALENES comprises 15% of the formula and carries a moderate-to-good safety score (ISS 6.5/10 grade A), indicating acceptable use levels in eau de parfum.
⚠One major ingredient (ETHANONE derivative at 12.5%) carries a Moderate grade safety rating. While approved for fragrance use, sensitive individuals should perform a patch test before regular application, particularly on broken or reactive skin.

Frequently Asked Questions

Is Constantinople safe for daily use?+

Constantinople's PSS score of 6.8/10 suggests it is generally safe for daily wear by most consumers. However, because it contains one ingredient with a Moderate safety grade, individuals with sensitive skin or fragrance sensitivities should perform a small patch test on the inner arm or behind the ear first. If no irritation occurs after 24 hours, daily application is typically acceptable.

Are there any ingredients I should watch out for?+

The most notable ingredient to be aware of is the ETHANONE compound at 12.5% concentration, which carries a Moderate safety classification. While this does not mean it is unsafe, it indicates greater caution is warranted compared to the Grade A ingredients like AMBROXAN and ACETYLCEDRENE. Avoid contact with eyes and discontinue use if redness or irritation develops.

What does a PSS of 6.8/10 (Grade B) mean?+

The PSS (Product Safety Score) of 6.8/10 with a Grade B indicates that Constantinople meets acceptable safety standards for consumer fragrance products, but is not in the highest safety tier. Grade B reflects a balanced risk-benefit profile: the fragrance is safe for the intended use when applied as directed, but contains ingredients that require standard precautions such as patch testing for sensitive individuals and avoiding contact with eyes.
