Title in Portuguese
Presença de elementos metálicos em cosméticos labiais: investigação dos impactos na saúde e o descarte no meio ambiente
Keywords in Portuguese
cosmético labial
ICP-OES
meio ambiente
metais pesados
saúde pública
Abstract in Portuguese
Os cosméticos labiais estão envolvidos em duas importantes discussões: os problemas de saúde pública e os problemas ambientais. A partir dessas informações, pretende-se analisar qual o impacto na saúde humana, verificar se há relação entre preço, duração e cor e investigar quais os prováveis impactos para o meio ambiente, supondo algumas vias de descarte. Os cosméticos analisados foram batons, divididos por marca, preço e cor. A primeira análise foi por fluorescência de raios-x (FRX). Em seguida, as matérias primas passaram por digestão com ácido nítrico e clorídrico sob aquecimento e foram diluídas com água destilada e filtradas. A seguir, foram realizadas leituras por espectrometria de emissão óptica com plasma indutivamente acoplado (ICP-OES). A partir dos resultados da análise por FRX (foram encontrados 18 elementos metálicos) e a matriz para análise por ICP-OES foi composta por: alumínio, cálcio, cádmio, cobalto, cromo, cobre, ferro, potássio, manganês, níquel, chumbo, silício e titânio. Apesar de terem sido identificados metais tóxicos (Ni, Mn, Cd e Cr) nas amostras, os batons analisados cumprem com o requerido pela legislação nacional em relação aos limites impostos para metais pesados (Pb, Cd, Ni, Cr e Mn) em cosméticos e alimentos. Entretanto, é importante destacar que as legislações cosmética e alimentícia possuem grandes diferenças quanto aos limites impostos para metais pesados. O estudo do descarte dos batons mostrou que mesmo os batons que são mais utilizados, há um desperdício de quase 1/3 do produto por conta da embalagem interna. Essa informação pode auxiliar em um consumo consciente dos batons, tanto para a quantidade desperdiçada, quanto ao risco associado à utilização de um conjunto de maquiagens (bases, sombras, rímel, blush e batom) com outros cosméticos (cremes, perfumes, esmaltes, tintas para cabelo). Risco esse, associado a possíveis problemas à saúde.

Metallic elements presence in lip cosmetics: investigation of health impacts and their disposal in the environment

Abstract in English
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 (creams, perfumes, nail polish, hair dyes).
