Resumo
Lip cosmetics are involved in two major discussions: the
public health and environmental problems. From this
information, we intend to analyze the impact on human
health, study the relationship among price, duration and
color and investigate what are the possible impacts on the
environment, assuming some waste disposal routes. The
cosmetics analyzed were lipsticks, divided by brand, price
and color. The first analysis was by x-ray fluorescence
(XRF). Then, the raw material went through digestion with
nitric and hydrochloric acids under heating, and diluted
with distilled water, then filtered. The following readings
were performed by optical emission spectrometry with
inductively coupled plasma (ICP-OES). From the results of
the analysis by XRF (found 18 metal elements), the matrix
for analysis by ICP-OES is composed of: aluminum,
calcium, cadmium, cobalt, chromium, copper, iron,
potassium, manganese, nickel, lead, silicon and titanium.
Toxic metals have been identified (Ni, Mn, Cd and Cr) in
the samples. Although the examined lipsticks showed
positive for toxic metals (Pb, Cd, Ni, Cr and Mn), their
levels comply with national legislation, regard to limits for
cosmetics and foods. However, it is important to note that
the cosmetic and food laws have great differences in the
limits for heavy metals. The study of disposal for lipsticks
showed that even lipsticks that are most used, there is a
waste of nearly 1/3 of the product due to the inner package.
This information may help in a conscious consumption of
lipsticks, including the risk associated with the use of a set
of makeups (foundation, eyeshadows, mascara, blush and
lipstick) with other cosmetics.
