Some science behind the scenes

Lipstick

Lipstick has a very worrying record for containing heavy metals.  Given that it is applied to the lips and inevitably is digested by either the woman or the men or women kissing her [or vice versa!], the potential for heavy metal poisoning is quite high if a woman wears lipstick for any length of time.  The following papers show that quite a range of extremely poisonous heavy metals are used in lipstick.  Lead............

Four hundred lipsticks available on the U.S. market in the spring of 2010 were tested for total lead content using the FDA's validated method. The analyses were performed by a private laboratory contracted by the FDA. The maximum lead level found was 7.19 mg Pb/kg. Thirteen of the 400 lipsticks were found to contain levels greater than 3.06 mg Pb/kg, the highest amount found in the initial survey. The average lead concentration found in the expanded survey was 1.11 mg Pb/kg, which was very close to the average of 1.07 mg Pb/kg found in the initial survey. Some statistically significant associations between lead level and parent company were found. PMID:  23193690

Laser Induced Breakdown Spectroscopy (LIBS) technique was applied to determine the concentrations of different toxic elements like lead, chromium, cadmium and zinc in four different lipstick brands sold at local markets in Saudi Arabia. These samples contain toxic elements like lead, cadmium and chromium which are carcinogen dermatitis, allergic and eczematous. Their extraction from human body takes over 40 years and accumulation in the body cause problems like disruption of nervous systems and kidney damage. They could trigger to systemic lupus erythematosus (SLE). In order to test the validity of our LIBS results, standard technique like (ICP-AES) was also applied. To the best of our knowledge, this is the first study where LIBS technique was applied for the measurement of toxic substances in lipsticks. The maximum concentration detected in four lipstick brands was much higher than the permissible safe limits for human use and could lead to serious health problems. It is worth mentioning that the lipstick is not a solid rather is in fluid state which is not trivial to analyze using LIBS technique. For this purpose, special treatment of the lipstick samples was necessary to analyze with our LIBS method.

many other studies are available on Pubmed that show that many other heavy metals are present as well.
