In personal care

An umbrella term for a mixture of scent-producing ingredients, which can number from a handful to hundreds of individual compounds, natural or synthetic. Regulations generally allow the full mixture to be listed under this single word to protect proprietary formulas.

Why it’s used

Gives a product its scent, and can also mask the natural smell of other raw ingredients.

What the evidence says

Because "fragrance" hides the individual components, it's impossible to assess as a single entity; some components inside a given fragrance blend, like certain allergens, are individually well studied, while the overall blend in any specific product is not disclosed. Contact allergy to fragrance ingredients overall is one of the more common cosmetic sensitivities identified in dermatology research.

This says what this database holds under these terms. It is not a finding that no research exists.

Context

Risk varies enormously by product and formula, since the term covers a wide and undisclosed range of ingredients; those with known fragrance sensitivities are generally advised to seek fragrance-free products rather than rely on this label to judge safety.

Insufficient dataToo little has been studied to say either way.

Rumors

  1. The single word "fragrance" on a label conceals dozens to hundreds of undisclosed chemicals.
