Gucci Bloom Eau de Parfum

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

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.

Solvent; safe.

Chemical UV filter added to stabilize fragrance color. Confirmed endocrine disruptor with estrogen-receptor binding and anti-androgen activity in cell and animal studies. Banned in Hawaii and several Pacific reef jurisdictions for environmental hormone effects. Pure aesthetic addition — unnecessary in a leave-on cosmetic.

Chemical UV filter (Uvinul A Plus) added to prevent fragrance color shift. Newer-generation but still benzophenone-derived; limited long-term human data.

Synthetic antioxidant. Possible endocrine disruptor (mild estrogenic activity in cell studies); banned as a food additive in several countries. Restricted in California Prop 65 listings for some uses.

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 with mild preservative function; contact dermatitis is documented in spray fragrances.

EU 26 fragrance allergen — one of the strongest dermal sensitizers in the IFRA standards. IFRA imposes strict use-level caps in leave-on products precisely because cinnamaldehyde causes high rates of contact dermatitis.

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.

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 with rose-like odor. Documented skin sensitizer; oxidation products are even more reactive.

IFRA / EU-declared fragrance allergen. Clove-derived; documented strong dermal sensitizer with IFRA-restricted use levels in leave-on products.

EU 26 fragrance allergen and a top-strength dermal sensitizer per IFRA. Use level in leave-on products is capped at 0.02% by IFRA because of its high allergic-contact-dermatitis rate.

IFRA / EU-declared fragrance allergen with floral-musky odor. Documented dermal sensitizer.

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

IFRA / EU-declared fragrance allergen. Synthetic jasmine-floral aromachemical; cinnamate-class compounds are a recognized contact-sensitizer family.

IFRA / EU-declared fragrance allergen with strong sensitizing potential — IFRA restricts maximum use levels in leave-on products specifically because of its high contact-allergy rate.
