Can you tell us which chemicals we should concentrate on?
PFAS ("forever chemicals"), flame retardants and phtalates, for starters:
PFAS:
Toxic ‘forever chemicals’ widespread in top makeup brands, study finds | The Guardian
The peer-reviewed study, published in Environmental Science & Technology, detected what the study’s authors characterized as “high” levels of organic fluorine, an indicator of PFAS, in over half of 231 makeup and personal care samples. That includes lipstick, eyeliner, mascara, foundation, concealer, lip balm, blush, nail polish and more.

The chemicals, which are highly mobile and easily move through the environment and humans, can be absorbed through the skin, absorbed by tear ducts or ingested. Green Science Policy Institute notes that people who wear lipstick can accidentally ingest several pounds of the product throughout their lives.
Companies often do not list PFAS on their labels when they use the chemicals, making them nearly impossible for consumers to avoid, Bruton said. Regulatory agencies often allow companies to claim PFAS as a trade secret; however, the study found fluorine was often present in products advertised as “wear-resistant”, “long-lasting” and “waterproof”.
Study finds alarming levels of ‘forever chemicals’ in US mothers’ breast milk | The Guardian
Toxic chemicals known as PFAS found in all 50 samples tested at levels nearly 2,000 times what is considered safe in drinking water
...
Evidence also suggests that the problem is getting worse. The study is the first in the US since 2005 to check breast milk samples, and shows an increase in the newer generation of PFAS, while older compounds that were phased out by industry are still present, and some at high levels.
The study also analyzed breast milk data from around the world and found PFAS detection frequency is increasing.
Among steps that the authors recommend pregnant women and mothers take to protect themselves are avoiding greaseproof carryout food packaging, stain guards like ScotchGard, waterproof clothing that uses PFAS, and cooking products with Teflon or similar non-stick properties, though manufacturers often do not disclose the chemicals’ use.
‘Forever chemicals’ found in home fertilizer made from sewage sludge | The Guardian
Sewage sludge that wastewater treatment districts across America package and sell as home fertilizer contain alarming levels of toxic PFAS, also known as “forever chemicals”, a new report has revealed.
Sludge, which is lightly treated and marketed as “biosolids”, is used by consumers to fertilize home gardens, and the PFAS levels raise concerns that the chemicals are contaminating vegetables and harming those who eat them.
Phtalates:
Chemicals in plastics damage babies' brains and must be banned immediately, expert group says | CNN
Synthetic chemicals called phthalates are damaging children's brain development and therefore must be immediately banned from consumer products, according to a group of scientists and health professionals from Project TENDR.
Phthalates Factsheet | Center for Disease Control and Prevention
Phthalates are a group of chemicals used to make plastics more flexible and harder to break. They are often called plasticizers. Some phthalates are used as solvents (dissolving agents) for other materials. They are used in hundreds of products, such as vinyl flooring, adhesives, detergents, lubricating oils, automotive plastics, plastic clothes (raincoats), and personal-care products (soaps, shampoos, hair sprays, and nail polishes).
People are exposed to phthalates by eating and drinking foods that have been in contact with containers and products containing phthalates.

What negative health effects have phthalates been shown to have in laboratory animals?
Very few studies have examined the health effects of phthalates on humans. In lab animals, phthalate exposure has been found to be associated with numerous reproductive health and developmental problems such as:
- Early onset of puberty.
- Interfering with the male reproductive tract development.
- Interfering with the natural functioning of the hormone system.
- Causing reproductive and genital defects.
- Lower testosterone levels in adolescent males.
- Lower sperm count in adult males.
Phthalates are weak endocrine disruptors and androgen blocking chemicals. This means that when absorbed into the body phthalates can either mimic or block female hormones, or in males, suppress the hormones involved in male sexual development.
