What is Beauty Made of?
What are you putting on your face?
Whatever your daily grooming regimen entails, it surely involves off-the-shelf cosmetic products: cleanser, shampoo, fragrance, makeup, moisturizer, sunscreen, the list goes on. But what are these products made of? How much do they differ by brand? Which brands produce products with potentially undesirable ingredients?
To explore this, I took a look at over 11,000 products listed on www.ulta.com. Check the data out yourself with the interactive web app below:
Commonly scrutinized ingredients
There are a host of common ingredients in cosmetics that have come under fire for allegedly posing health or environmental hazards. This analysis explores the prevalence of a few of these ingredients:
- Coal Tar Dyes
- Palm Oil
- Sunscreen Chemicals
Some more information on how each was identified and the alleged hazards they each pose is available below.
Note: This app does not investigate claims that any of these ingredients are actually nefarious; it merely identifies which products contain them.
Most common ingredients
Of the list of 11,230 products examined, 9,067 (81%) contained at least one of the above ingredients. When we break this out by family of ingredients, we see that fragrance is by far the most common (present in 5,822 ingredients), followed by coal tar dyes (4,346).
When we split this out by top level category, we see that most of these products are hair, skincare, and makeup products.
It's unsurprising that fragrance is the most common ingredient. According to the FDA:
If a cosmetic is marketed on a retail basis to consumers, such as in stores, on the Internet, or person-to-person, it must have a list of ingredients. In most cases, each ingredient must be listed individually. But under U.S. regulations, fragrance and flavor ingredients can be listed simply as “Fragrance” or “Flavor.”
Here's why: the FDA requires the list of ingredients under the Fair Packaging and Labeling Act (FPLA). This law is not allowed to be used to force a company to tell “trade secrets.” Fragrance and flavor formulas are complex mixtures of many different natural and synthetic chemical ingredients, and they are the kinds of cosmetic components that are most likely to be “trade secrets.” To learn more, see the regulation on cosmetic ingredient labeling and the Federal Register notice for this regulation, which addresses “trade secrets” and the FPLA.
Seeing coal tar dyes predominantly in makeup also seem reasonable, as pigments are a crucial component of makeup.
Top offending brands
The majority of brands -- 347 out of 383 -- have at least one product with at least one commonly scrutinized ingredient. Below are the brands with the highest number of products that meet this criteria.
It's not surprising that Ulta makes the top of the list, since the brand is the most represented one on its own site. We can also look at the brands ordered by the proportion of their products which contain at least one scrutinized ingredient (only brands with 50+ total products are considered below).
Digging in a bit, we see that Yes To actually addresses the presence of fragrance in their products on their website.
Yes To's fragrance is a mix of essential oils, natural aromatic chemicals and other synthetic ingredients that are approved by RIFM (Research Institute for Fragrance Materials). The synthetic ingredients are used when there are no natural alternatives to create the scent.
