THE FRAGRANCE LOOPHOLE
Purportedly in the interest of safeguarding commercially valuable intellectual property, personal care product manufacturers are permitted to conceal the composition of the fragrances they use in their products. An ingredient listed on a product label as “fragrance” may be composed of dozens of different synthetic chemical compounds, none of which are specifically identified on the label or the manufacturer’s website. Further, even products labeled ‘fragrance free’ have been shown to contain fragrance ingredients, typically due to the use of these compounds as preservatives or as agents to mask the odors of other chemicals in the product.1 Yet fragrance is the most common cause of contact dermatitis associated with personal care products.2 Even more alarmingly, chemical analyses of cosmetics and personal care products containing undisclosed “fragrance” ingredients have identified known allergens, asthma triggers, allergens, sensitizers, endocrine disruptors, carcinogens and neurotoxins.3,4,5
Due to the strong evidence of the potential negative health impacts of unspecified fragrance ingredients, Think Dirty® automatically assigns any product that lists “fragrance” on its label a rating of 7 or higher.
The assignment of numerical ratings based on the results of scientific studies is necessarily a subjective process.
