Can some personal care product chemicals be linked with cholesterol risk?
Use caution with triclosan and some benzophenone UV-filter chemicals. A 2026 Environmental Science and Technology case-control study found links between higher PPCP exposure, thyroid hormone changes, and hyperlipidemia risk in adults.
What is actually in it
Personal care products can include many chemicals. The study behind this page looked at pharmaceutical and personal care product chemicals, often shortened to PPCPs. Two chemicals named in the findings were triclosan and benzophenone-related UV-filter chemicals.
Triclosan has been used in some antibacterial soaps and personal care products. Benzophenone-related chemicals can be used in some sunscreen and fragrance-related products. Product labels matter.
What the research says
A 2026 Environmental Science and Technology study compared 103 adults with hyperlipidemia and 419 adults without it in China. The strongest single-chemical associations were for 4-hydroxybenzophenone and triclosan. The study also found that thyroid hormone changes partly explained the links for triclosan, BP-1, and total PPCP exposure.
This was an adult case-control study. It does not prove that one soap or lotion raises cholesterol. It also is not baby evidence. It does support choosing simpler personal care products and avoiding antibacterial claims you do not need.
What to do at home
Skip personal care products that list triclosan. Use plain soap for everyday handwashing. Choose fewer scented products when possible, especially for babies and pregnant people.
For cholesterol or thyroid concerns, talk with a clinician. Product swaps are a prevention step, not medical care.
