Frequently Asked Questions
Is Molecule 01 Patchouli safe for daily use?+
The Grade B PSS rating suggests it is generally safe for regular use by most consumers. However, because it contains 80% synthetic woody compounds at relatively high concentrations, daily application should be evaluated individually—especially if you have a history of fragrance sensitivity or reactive skin. Start with limited application and observe for any irritation over 48 hours.
Are there any ingredients I should watch out for?+
The two dominant ingredients—Tetramethyl Acetyloctahydronaphthalenes (80%) and Ethanone, 1-(1,2,3,4,5,6,7,8-Octahydro-2,3,8,8-) (75%)—are synthetic compounds rated Grade A and Moderate respectively. Neither is flagged as a common allergen, but their combined concentration is substantial. If you have eczema, psoriasis, or known fragrance allergies, consult a dermatologist before use.
What does a PSS of 6.5/10 (Grade B) mean?+
PSS (Product Safety Score) is an independent safety assessment. A Grade B at 6.5/10 indicates the product meets baseline safety standards but has moderate rather than exceptional safety margins. It is suitable for general consumer use, though not rated in the highest safety tier. Grade B products are commonly available and widely used with no special restrictions.
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.
