Consumption of cosmetic products by the French population second part: Amount data.

The aim of the study was to assess the amount per use of cosmetic products consumed at home by the adult, child and baby French population. 1078 men and women participated in the study which was performed in four cities of France. This enquiry was performed on 106 cosmetics including general hygiene, skin care, hair care, hair styling, make-up, fragrances, solar, shaving and depilatory, and baby products. Coupled to frequency data previously obtained (Ficheux et al., 2015), these amounts per use data will be used in order to assess the exposure to cosmetics by the French population. These current exposure values could be useful for safety assessors and for safety agencies.

Exposure method development for risk assessment to cosmetic products using a standard composition.

In a risk assessment of cosmetic products, it is necessary to know both qualitative and quantitative compositions. Currently, European Regulation No. 1223/2009 requires the industries to provide ingredient lists for finished cosmetic products but not their concentrations. Ingredient concentrations are available in few bibliographic references but in an incomplete and approximate way. In this study, we propose a method to qualitatively and quantitatively estimate the composition of a cosmetic product. This method has the advantages of being applicable to all cosmetic products and supplying concentration data for all ingredients. The results obtained seem quite fair compared to literature data. Applied to nail polish as an example, this method can be used to assess exposure per ingredient according to the Monte Carlo probabilistic method. It should be promising to assess the consumer risk to cosmetic product compositions.

Probabilistic assessment of exposure to nail cosmetics in French consumers.

The aim of this study was to assess probabilistic exposure to nail cosmetics in French consumers. The exposure assessment was performed with base coat, polish, top coat and remover. This work was done for adult and child consumers. Dermal, inhalation and oral routes were taken into account for varnishes. Exposure evaluation was performed for the inhalation route with polish remover. The main route of exposure to varnishes was the ungual route. Inhalation was the secondary route of exposure, followed by dermal and oral routes. Polish contributed most to exposure, regardless of the route of exposure. For this nail product, P50 and P95 values by ungual route were respectively equal to 1.74 mg(kg bw week)(-1) and 8.55 mg(kg bw week)(-1) for women aged 18-34 years. Exposure to polish by inhalation route was equal to 0.70 mg(kg bw week)(-1) (P50) and 5.27 mg(kg bw week)(-1) (P95). P50 and P95 values by inhalation route were respectively equal to 0.08 mg(kg bw week)(-1) and 1.14 mg(kg bw week)(-1) for consumers aged 18-34 years exposed to polish remover. This work provided current exposure data for nail cosmetics, and a basis for future toxicological studies of the uptake of substances contained in nail cosmetics in order to assess systemic exposure.
