Fragrance is a complex mixture of ingredients that can contain up to thousands of undisclosed chemicals, including some that may have negative health effects. The term "fragrance" or "parfum" on a product's ingredient list is not specific and can refer to a blend of compounds that create the product's scent. Many personal care and household products contain fragrance, and it is often used to create pleasant odors or mask unpleasant ones. However, some fragrance ingredients have been linked to health concerns such as endocrine disruption, asthma, and even cancer. The International Fragrance Association (IFRA) has published a list of fragrance ingredients, some of which have evidence linking them to harmful health effects. To make more informed choices as a consumer, it is recommended to look for products that disclose their fragrance ingredients on the label or are fragrance-free. Additionally, choosing products from brands that are transparent about their ingredients can help reduce exposure to potentially harmful fragrance chemicals
