Vaseline is a wide known product that is used to keep dry lips moisturized. One of the biggest ingredients in vaseline is petroleum. Petroleum is a liquid mixture of hydrocarbons that is present in suitable rock strata and can be extracted and refined to produce different fuels, such as: gasoline, kerosene, and heating oil. Plastic and vaseline also contain petroleum. Well, according to health-report.co.uk, “Impurities in Petroleum Jelly or commonly known as Vaseline, are under suspicion as a carcinogen in Breast Cancer – Petrolatum Banned in products in the EU – Long term damage to health becoming evident – side effects from impurities in the manufacturing process implicated in causing cancer”. There also has been a study done on cancer incidences of workers in the Swedish petroleum industry. There, scientists found that operators at Swedish refineries had an increased risk of leukemia due to a possible exposure to benzene (a colorless volatile liquid hydrocarbon, C6H6, present in coal, tar and petroleum).
Vaseline is linked to petroleum impurity (PAH) and breast cancer because agencies allow any amount of petroleum of any purity in personal care products; many of which are applied directly to the lips (vaseline) and swallowed. Although there isn’t an extremely well-known link between petroleum and cancer, there have been studies that obviously arise a lot of skepticism on the safety of using products containing petroleum. In most cases, a consumer buying a product containing petroleum has no way to know if the ingredients are low in carcinogenic PAH’s or not. So, be careful, and look at the list of ingredients on your lip product or other products to see if petroleum is an ingredient. Maybe staying away from vaseline would be safe too.
