Fragrance or parfum does not denote plant extracts and essential oils, rather it's a term that can refer to any one of hundreds of chemicals. Some are safe, but most are carcinogens, allergens, or endocrine disruptors. Most beauty products contain this "ingredient". In 2007 the family of ingredients constituting the word fragrance was named "Allergen of the year" by the American Contact Dermatitis Society. A new way companies have found around the fragrance concern is to label their products fragrance-free. Don't be fooled - all that means is that fragrance chemicals have been added to the products to mask the natural aromas of the base ingredients.
