Undisclosed fragrance

A single word on a label that can stand for dozens of undeclared ingredients, protected as trade secret. Fragrance is the most common way a product hides what is in it, and it is where phthalates most often sit. A product cannot be assessed properly when one line of its label is sealed.

What a flag here means. Reported and likely mean we found real evidence, a published ingredient, a test result or a recall. Possible means the material or the category makes it credible and nobody has ruled it out. 234 products were checked for it and came back with nothing known. A flag is not a measurement, and we say which is which on every product page.

Where we found real evidence

Reported or likely, lowest scoring first. Not plausibility.

  • Individual users report occasional contact dermatitis with period underwear, typically linked to gusset coatings or dyes. Modibodi's anonymous coating increases risk of unidentified allergens. Anecdotal reports exist but no clinical study of this specific prod

  • Always Maxi pads contain adhesive and optional fragrance (in some variants). Fragrance and adhesive components are known triggers for vulvovaginal irritation and contact dermatitis in susceptible users; unscented variants may reduce risk.

  • Carefree Maxi Overnight pads are scented with Acti-Fresh fragrance. Fragrance mixtures in period products are a known trigger for vulvovaginal contact dermatitis, particularly in people with sensitive skin or existing irritation. The specific fragrance ingredi

  • Incontinence products can trigger irritant or allergic dermatitis in sensitive individuals, though this is more often mechanical (moisture occlusion) than chemical. Cellulose itself is hypoallergenic, but bleaching agents and processing residues are not typica

  • Always Discreet products are fragranced and adhesive-backed. Consumer reports of localized dermatitis exist but are not epidemic; individual sensitivity varies. Fragrance allergen identity is not fully disclosed on packaging.

  • Anecdotal reports in period-product reviews flag irritation from synthetic underpads with unknown backing, particularly in users with sensitive skin or vulvovaginal conditions. Lack of material transparency makes individual risk prediction impossible.

  • Individual reports of rashes or irritation exist across Playtex pad lines, typically linked to adhesive sensitivity or cellulose processing residues rather than intentional additives. Allergen labeling is absent on most period pads; sensitivity is person-depen

  • User reports of genital itching, irritation, and allergic reactions attributed to Always pads exist on consumer forums and health sites, though no formal causal link has been established. The nonwoven materials themselves are generally safe, but unidentified a

  • Clinique mascaras typically contain fragrance; undisclosed fragrance components are common allergens and can trigger contact dermatitis on sensitive eyelids and conjunctiva. Specific allergen screening is not published by the brand.

  • Clinique High Impact formulations typically include fragrance or fragrance-masking agents. Contact dermatitis and eye irritation from mascara fragrance are well-documented; sensitive individuals should patch-test or choose fragrance-free waterproof alternative

  • Urban Decay mascaras are fragranced cosmetics; mascara is applied near mucous membranes and can trigger irritation in sensitive individuals. No specific safety recalls for Perversion exist, but user reports of eye redness and stinging are consistent with conve

  • Cosmetic fragrances in mascaras can trigger eye irritation or contact dermatitis in sensitive users. Lancôme lists fragrance as an ingredient but does not break down allergens; case reports of irritation from waterproof mascaras exist in dermatological literat

Which products contain undisclosed fragrance?

More than in anything else we grade. 55 of the 55 lip balm & long-wear lipstick we scored carry a flag for it, which is 100%. The full breakdown per product is on each product page.

How do you know?

We do not lab test. Every grade here is built from published ingredient lists, materials, certifications, brand disclosures, recalls and third party lab results where those already exist. Where a product has been independently tested we use that result and say so, and where a brand publishes nothing we score the silence rather than guessing.
