Frequently Asked Questions
Is Viper Green safe for daily use?+
Viper Green can be used daily by most consumers. However, like all fragrances, apply to pulse points or clothing rather than near eyes or sensitive areas. If you have particularly reactive skin, perform a patch test on a small area first. Discontinue use if persistent irritation develops.
Are there any ingredients I should watch out for?+
Yes. Benzyl Salicylate (8.8%) carries an eye irritation warning (Category 2B, H320) and should never contact eyes directly. Additionally, two ingredients—an octahydro compound and tetrahydro-isobutyl-methylpyran—both carry moderate ISS scores (6.6/10) and warrant normal fragrance precautions. If you have known salicylate sensitivities, consult a dermatologist before use.
What does a PSS of 6.9/10 (Grade B) mean?+
The PSS (Product Safety Score) Grade B indicates moderate safety. The product is generally acceptable for consumer use but has some ingredient-level considerations—in this case, the Benzyl Salicylate eye irritation flag. It is neither top-tier (Grade A/A+) nor a safety concern (Grade C or lower). Standard fragrance safety practices apply.
