The concern

Preservative and fragrance allergen - the EU requires it to be declared

Benzyl alcohol is both a preservative (permitted up to 1% in the EU) and one of the fragrance substances the EU requires to be named on a label because it can cause contact allergy in sensitised people. It is information for someone who knows they react to it, not a general hazard.

Method and limits

  • Prevalence counts published products whose decoded ingredient list matches this substance or one of its label synonyms, using the same matching the score itself uses. It describes our catalogue of 912 products, not the Indian market as a whole.
  • Presence is not dose. An ingredient list gives order, not quantity, unless the pack declares a percentage. Nothing here estimates how much of this substance any product contains.
  • A classification is not a verdict on a product. An agency classifies a substance under defined conditions of exposure; whether that matters in a given food or cosmetic depends on route, concentration and use.
