TETRAHYDRO-METHYL-PHENYL-PYRAN.

This ingredient functions exclusively as a fragrance component and is not associated with 'dusting' as a metric for active ingredients providing skin benefits.

No specific Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) assessment was found for TETRAHYDRO-METHYL-PHENYL-PYRAN under its exact name. The Australian Industrial Chemicals Introduction Scheme (AICIS) assessed a related compound (CAS 60466-73-1) as slightly irritating to skin and eyes, though irritation effects are not anticipated at low end-use concentrations up to 0.5% in cosmetic products. However, the European Chemicals Agency (ECHA) GHS classification for 'tetrahydro-4-methyl-2-phenyl-2H-pyran' (CAS 94201-73-7), a close variant, indicates a 100% likelihood of 'Causes skin irritation,' 73% for 'May cause an allergic skin reaction,' and 37.8% for 'Causes serious eye irritation.' Toxicological data for related 'Rose Oxide' isomers on the REACH platform reported toxic effects on the reproductive organs of male rats at high systemic doses (300 or 1000 mg/kg body weight per day). The International Fragrance Association (IFRA) recommends usage levels for 'rose pyran' (CAS 94201-73-7) up to 5% in the fragrance concentrate, which differs from maximum final product concentrations. No FDA status as a skincare active has been identified.
