Why This Score

✔Ethylene Brassylate (15.0%) is the primary ingredient and scores 10.0/10 on the Ingredient Safety Scale, indicating excellent safety profile with established dermatological tolerance.
✔1,4-Dioxacycloheptadecane-5,17-Dione (12.5%) achieves a perfect ISS score of 10.0/10 (Grade A+), demonstrating strong safety data and low irritation potential.
⚠Tetramethyl Acetyloctahydronaphthalenes comprises 10.0% of the formula with a moderate ISS score of 6.5/10. While acceptable, individuals with sensitive skin should perform a patch test before regular use, as synthetic musks can occasionally trigger reactions in susceptible persons.

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 7/24 safe for daily use?+

7/24 shows acceptable safety metrics (PSS Grade A-) for general daily use by most consumers. However, the 10% concentration of Tetramethyl Acetyloctahydronaphthalenes suggests patch testing first if you have a history of fragrance sensitivity or reactive skin. Always follow manufacturer application guidance and discontinue if irritation occurs.

Are there any ingredients I should watch out for?+

The primary concern is Tetramethyl Acetyloctahydronaphthalenes, a synthetic musk compound that scores 6.5/10 on the safety scale—the lowest among top ingredients. Individuals sensitive to synthetic musks, pregnant persons, or those with compromised skin barriers should consult a dermatologist before use. The remaining major ingredients score 7.0/10 or higher.

What does a PSS of 7.2/10 (Grade A-) mean?+

The Product Safety Score (PSS) of 7.2/10 with Grade A- reflects an above-average safety profile based on ingredient composition and established toxicological data. This grade indicates the product is generally suitable for consumer use but is not flawless—hence the 'minus' qualifier. It is not the highest safety tier but represents responsible formulation.

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.
