Benzyl Alcohol and EU allergens

The EU requires benzyl alcohol to be listed on the packaging if it exceeds 0.001% in rinse-off products or 0.0001% in leave-on products. This does NOT mean it is dangerous for everyone — allergy is specific and occurs in ~1-2% of the population. If you have sensitive skin or a reaction to fragrances — look for 'fragrance-free' and check for the presence of benzyl alcohol.
