What is it?
The word fragrance or parfum on a product label is a legal loophole that can conceal a blend of anywhere from a handful to several hundred individual chemical compounds. Under EU and US regulations, fragrance ingredients are classified as trade secrets and do not need to be individually disclosed on product labels. A typical synthetic fragrance formula contains phthalates (as fixatives and carriers), synthetic musks (which accumulate in body fat), aldehydes, toluene, and potentially dozens of other sensitising or endocrine-disrupting compounds. The fragrance industry self-regulates through IFRA (International Fragrance Association), but IFRA has no legal enforcement power and its safety standards are widely criticised by toxicologists.
What it does to your body
Endocrine disruption via phthalates
Phthalates concealed within fragrance formulas disrupt testosterone and oestrogen signalling, with reproductive and developmental consequences.
Respiratory sensitisation
Fragrances are the leading cause of occupational asthma in hairdressers and cleaning staff, and a common trigger for general airway reactivity.
Synthetic musk accumulation
Nitromusks and polycyclic musks are highly lipophilic and bioaccumulate in human fat tissue and breast milk with years of exposure.
Skin sensitisation and allergy
Fragrance is one of the most common triggers of allergic contact dermatitis; some fragrance compounds are known potent skin allergens.
Neurological effects
VOCs in fragrance compounds contribute to headaches, nausea and cognitive effects in sensitive individuals, particularly in enclosed spaces.
How widespread is the problem?
An estimated 1 in 3 adults reports adverse health effects when exposed to fragranced products. A 2019 Australian study found fragrance from consumer products contributed more to urban ozone-forming emissions than petrol vehicles. Synthetic musks are now detected in virtually all human tissue samples tested globally.

EWG Not So Sexy: Hidden Chemicals in Perfume
EWG analysis found an average of 14 undisclosed chemicals per fragrance formula, including hormone disruptors and sensitisers not listed on labels.
Anne Steinemann Fragrance Emissions Study
Found that fragranced consumer products emit numerous VOCs, some classified as hazardous, and that fragrance emissions contribute significantly to urban air pollution.
Campaign for Safe Cosmetics Fragrance Disclosure
Documents the ongoing failure of voluntary fragrance ingredient disclosure and the gap between industry self-regulation and independent toxicological assessment.
Phthalates used as fragrance carriers clear within 24 to 48 hours. Synthetic musks, however, are highly lipophilic and accumulate in fatty tissue over years of exposure. Switching to fragrance-free products or those using only disclosed essential oil ingredients is the most effective strategy.
