Why This Score

✔High water content (15.0% AQUA, grade A+) supports skin hydration and reduces irritation risk from alcohol base.
✔Denatured alcohol (65.0%, grade A-) is a standard fragrance solvent with established safety profile at typical EDP concentrations.
⚠Contains an unresolved compound at 12.5% concentration (ISS 6.6/10, Moderate grade) with limited publicly available safety data; recommend patch testing before full application.

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 Citizen X safe for daily use?+

For most people, yes—the PSS Grade B indicates moderate safety. However, because the formula contains one ingredient with a Moderate safety grade and limited transparency, we recommend starting with patch testing on a small area of skin (inner wrist or behind the ear) for 24–48 hours before daily application. Discontinue use if redness, itching, or irritation develops.

Are there any ingredients I should watch out for?+

The main ingredient to be aware of is the unresolved compound at 12.5% concentration, which carries a Moderate safety grade. While the high alcohol content (65%) is standard for eau de parfums, it can cause dryness in sensitive skin. Avoid contact with eyes and mucous membranes. If you have a known fragrance sensitivity, consult a dermatologist before use.

What does a PSS of 6.6/10 (Grade B) mean?+

The Product Safety Score (PSS) of 6.6/10 with Grade B indicates Citizen X has moderate safety—above the lowest tier but not in the highest safety category. This score reflects the overall hazard profile of all ingredients combined. Grade B means the product is acceptable for general consumer use under standard conditions but may carry minor concerns that warrant precautionary practices like patch testing, especially for sensitive individuals.

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.
