Cosmetic, sunscreen chemical raises cancer risk

SINGAPORE: A Singapore research team has said a chemical commonly found in cosmetics and sunscreen may potentially cause cancer. The preliminary study on nanotoxicology was led by the research team from Nanyang Technological University (NTU). The study found that when the chemical, zinc oxide, is turned into nano-sized particles, it is able to enter human cells that may damage the user's DNA. When in contact with cells that lack a tumour suppressor, called p53, cancerous cells may develop. The team said the findings suggest that companies may need to reassess the health impact of nano-sized zinc oxide particles used in everyday products.
