According to a new study published in the journal Environment & Health, 98% of everyday products (such as shampoos, baby lotions, and sunscreens) contain chemicals not listed on their labels, while 85% were found to contain substances harmful to human health.
The scientists analyzed 113 products. The findings revealed that while an average of 16 ingredients were listed on the label, actual laboratory testing identified an average of 51 chemicals per product. Furthermore, over 25% of the products contained chemicals (such as phthalates and parabens) that were explicitly guaranteed on the packaging not to be present.
These hidden chemicals can enter products via raw materials, processing equipment, or packaging. As a result, products marketed as “natural,” “organic,” or “hypoallergenic” often still contain endocrine disruptors and allergens.
Study author Jenna Hua notes that simply reading the label is not enough for consumers. The researchers urge regulators not to rely solely on manufacturer-provided ingredient lists when verifying product safety, but instead to implement mandatory laboratory testing of final, packaged products.
