FAQ

Is tetrahydro-methyl-methylpropenyl-pyran safe during pregnancy?

No harmonised CLP reproductive classification for this substance was found and the Cosmetic Ingredient Review (CIR) review of rose/rose-derived ingredients did not identify developmental or reproductive toxicity data for rose constituents. Some animal and pharmacology studies of rose oxide exist but do not report teratogenicity; therefore default hazard = 0. Dermal/topical exposure is expected to give low but measurable absorption for a small monoterpene like rose oxide, so exposure = 1. (CIR review; PubMed studies; supplier data/SDS).

Is tetrahydro-methyl-methylpropenyl-pyran safe while breastfeeding?

No data showing specific effects via lactation or classification for damage via lactation; no mechanistic evidence for transfer or lactation-specific toxicity was found. Systemic absorption from topical use is low but measurable (so a low exposure potential to nursing parent).

Is tetrahydro-methyl-methylpropenyl-pyran safe for baby skin?

No infant-specific reproductive or developmental toxicity evidence was located. Per scoring rules, exposure for baby skin is increased by +1 relative to adults because rose oxide is a small, skin‑penetrating fragrance molecule with measurable absorption, and infant skin has higher surface‑area‑to‑weight and immature barrier function.

VeriMom scores tetrahydro-methyl-methylpropenyl-pyran at 33/100 (high risk) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
