Mother-daughter pairs will partake in an educational session at the baseline visit, which will cover topics on reading product labels, cleaning habit, and cooking methods for reducing environmental exposures. Educational materials will be adapted from the Environmental Protection Agency (EPA) and other accredited sources. Participants will also be introduced to free resources for consumer product safety information, such as the Detox Me phone application. Participants in the intervention arm will receive a 6-month supply of soap, lotion, deodorant, lip balm, a mop, cleaning cloths, and an air filter to take home with them. Mother-daughter pairs in both study arms will return for a second clinic visit 6 months after the pre-intervention visit for blood and urine sample collection, Optical Spectroscopy (OS) measurement, and questionnaire completion.

Control arm participants will be offered the chemical-free products, cleaning supplies, and air filter at this time.

This study will focus the intervention on ways at the individual level to reduce sources of Polycyclic Aromatic Hydrocarbons (through cooking methods, exposure to cigarette smoking, indoor air filters) and also individual ways to reduce sources of other Endocrine Disrupting Chemicals. Mother-daughter pairs will partake in an educational session at the baseline visit, covering topics on reading labels, cleaning habits, and cooking methods for reducing exposures. Participants will also be introduced to free resources for consumer product safety information.

The control arm will be offered the intervention products at this time.

Breast tissue composition will be assessed at each clinic visit using an Optical Breast Spectroscopy machine, a minimally invasive procedure that is investigational and not currently FDA-approved. This machine places a light source on 4 different locations of the breast (at 12, 3, 6, and 9 o'clock) and reads the reflected light through the breast tissue. The OS exam will be completed twice on each side of the chest so that 8 measures are taken from the left breast and 8 measures will be taken from the right breast (with each measurement taking no more than a minute). A Monte-Carlo light propagation simulation technique (FullMonte) will be used to extract breast tissue concentration of lipid (mg/cm^3).
