The Taking Stock study seeks to explore the impacts of beauty products on Black and Latina women in California.
Our community-driven pilot study is guided by the overall hypothesis that consumer product use patterns contribute to exposure and health inequities observed in Black and Latina women in California.

About Our Research
Our goal is to understand if the products used by women of color might harm their health.
The Environment & Our Health
The public health burden of breast cancer and other reproductive illnesses in California is immense. Breast cancer is the most common cancer among women in California. However, women are not affected equally by the disease as there are significant racial/ethnic differences in incidence and mortality. While the rate of new breast cancer diagnoses have historically been highest among White women, rates among Black women have been rising and rates are now converging with those of White women. Mortality remains highest among Black women, who on average, are diagnosed at younger ages and have more aggressive forms of the disease. New breast cancer diagnoses and mortality rates are lower among Latinas; however, breast cancer is the most common cancer among Latinas.
Environmental factors, including chemical exposures, may play an important role in the development of diseases like breast cancer. We understand today that the majority of breast cancer risk can be attributed to factors that may be modifiable, and not just genetics. This raises important questions about what these factors may be and the possibility of creating interventions. There is a need to identify and eliminate environmental hazards that may be contributing to health disparities among California women.
Chemicals found in consumer products could be an important source of chemical exposures. These have been a little considered a source of harm to our health and may contribute to health disparities. Commonly used consumer products can contain hormone disruptors endocrine disrupting chemicals (e.g., cosmetics or air fresheners), mammary gland carcinogens (e.g., cleaners and pesticides) and/or chemicals that affect how the mammary gland develops mammary gland toxicants (e.g. stain repellents and plastics).
Our Research Questions
Case Study in South Los Angeles
The Taking Stock Study advances research on consumer product chemicals and health impacts by combining our community capacity to collect data with multidisciplinary research in environmental exposure science, epidemiology, environmental justice, breast cancer toxicology, and qualitative research methods.
South Los Angeles is a 51-square mile region of Los Angeles including 25 neighborhoods within the city and 3 unincorporated neighborhoods in the county. It is home to a majority Black and Latinx population and is recognized by the California Environmental Protection Agency as an environmental justice neighborhood. South LA faces cumulative risks from multiple place based polluting industries and freeways, combined with a vulnerable population with high percentages of poor and non-White residents.
What We Found
Taking Stock Study: Personal care product use among diverse women in CA.
What we learned: Women in the study reported using, on average, 8 products a day, with some using up to 30 products daily.
For 28 of the 54 products, use varied significantly by race/ethnicity, with the largest difference seen between Black and White women.
Black women reported using a higher number of hair products and more menstrual/intimate products.
Hispanic/Latinx and Asian women reported using more cosmetics than Black and White women.
70% of women prefer scented versions of the products they use. Fragrance is an umbrella term that may contain dozens of undisclosed and unregulated chemicals.
We asked women about 54 personal care products: cosmetics, hair, menstrual/intimate, leave-on or rinse off products, scented products.
Background: Women of color, particularly Black women, are disproportionately exposed to consumer product chemicals, including parabens and phthalates, which are endocrine disruptors and linked to cancer.
Exposure inequities: Socio-cultural factors, as well as racial discrimination including colorism and hair texture preference can often influence product use, which may lead to exposure inequities.
Health Effects: Early puberty, pre-term birth, uterine fibroids, breast cancer, infertility.
Recommendations to reduce the effects:
Reduce your use of fragranced products.
Reduce your overall product use.
Try to find and use products without parabens and phthalates. Look up your products on one of the apps below:
