Tom Ford Ombré Leather Eau de Parfum

Trade-secret blanket term that legally conceals dozens to hundreds of individual aromachemicals. Designer fragrance blends almost always contain synthetic polycyclic musks (Galaxolide, Tonalide) — endocrine disruptors that bioaccumulate in human fat tissue, breast milk, and wastewater — alongside Ambroxan, Iso E Super, and historically DEP phthalate solvents. No disclosure obligation in the US.

Polycyclic synthetic musk on the EU 26 allergen list (as of 2023 update). Confirmed endocrine disruptor: anti-estrogenic in cell assays, bioaccumulates in human fat tissue, breast milk, and umbilical-cord blood. Persistent environmental pollutant detected in surface water and wildlife globally. EPA and ECHA have flagged it as PBT (persistent, bioaccumulative, toxic).

EU 26 fragrance allergen and well-documented strong dermal sensitizer. The closely related Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde (HICC / Lyral) was banned by the EU in 2021 for the same class of sensitization issues; hydroxycitronellal itself remains restricted but is repeatedly cited in patch-test registries as a top fragrance allergen.

EU 26 fragrance allergen; aggressive 'green-violet' aromachemical. IFRA caps it at very low levels because of its high contact-sensitization potential, including airborne contact allergy.

IFRA / EU-declared fragrance allergen and weak photoallergen. Recent SCCS reviews have raised concerns about possible endocrine activity at typical fine-fragrance use levels.

IFRA / EU-declared fragrance allergen. Air-oxidized linalool hydroperoxides are confirmed contact sensitizers — exposure is high in spray-on fragrance.

IFRA / EU-declared fragrance allergen; recognized dermal sensitizer with cumulative-exposure concerns.

IFRA / EU-declared fragrance allergen and known dermal sensitizer; SCCS has flagged repeated leave-on exposure as a concern.

IFRA / EU-declared fragrance allergen with rose-like odor. Documented skin sensitizer; oxidation products are even more reactive.

IFRA / EU-declared fragrance allergen. Oxidizes on skin and in the bottle into stronger sensitizers; one of the top causes of fragrance contact dermatitis. Required label disclosure means it is present above 0.001% in this leave-on product.

IFRA / EU-declared fragrance allergen; oxidizes in air to cinnamaldehyde, a strong contact sensitizer.

IFRA / EU-declared fragrance allergen. Recognized dermal sensitizer; one of the most frequently cited fragrance allergens in patch-test studies.

IFRA / EU-declared fragrance allergen; cinnamate-class compounds are frequent contact sensitizers.

Pine-terpene aromachemical. Oxidizes on air exposure into stronger sensitizers (alpha-pinene hydroperoxides are documented contact allergens).

Volatile terpene with documented neurological toxicity at higher doses; respiratory irritant in spray products. EU restricts use levels in leave-on cosmetics.

Ethanol-based solvent carrier (~80% of formula). Drying to skin but otherwise inert; denaturant identity is not disclosed.

Solvent; safe.

Natural spicy-woody terpene found in clove and cannabis essential oils. Lower allergenic potential than monoterpenes.

Natural essential oil; contains naturally occurring sensitizing constituents (limonene, linalool — listed separately when present). Generally moderate allergen potential.

Synthetic macrocyclic lactone musk; lower toxicity profile than polycyclic musks (Galaxolide/Tonalide). Not on the EU 26 list.

Natural essential oil. Generally low allergenic potential at fine-fragrance levels.
