Abstract [en]

Per- and polyfluoroalkyl substances (PFASs) are a large group of compounds consisting of a fully or partially fluorinated alkyl chain and a functional head group. The structure of PFASs yields molecules that are highly desired in both industrial and commercial applications were properties such as oil and water repellency are needed. However PFASs have also been linked to health problems such as cancer, hepatoxicity and reproductive toxicity. Recently the analysis of total organic fluorine (TOF) and PFASs in several matrices have revealed the presence of unidentified organofluorine (OF) compounds. In addition fluorinated compounds have been identified in various personal care products (PCPs).

The aim of this study was to quantify the extractable organic fluorine (EOF) content and contribution of individual PFASs in various cosmetic products in order to determine the amount of unidentified OF and asses the possibility of a risk to human health. Determination of EOF was conducted using combustion ion chromatography (CIC) and followed up through target analysis by liquid chromatography tandem-mass spectrometry (LC-MS/MS).

Fluorinated compounds were detected in 21 of the 32 analyzed samples in concentrations ranging up to 242 μg/g. Target analysis established polyfluoroalkyl phosphate esters (PAPs) as the main contributing compounds to total PFASs, followed by perfluoroalkyl carboxylic acids (PFCAs). In addition perfluoroalkyl sulfonic acids (PFSAs) and fluorotelomer sulfonic acids (FTSAs) were detected. Unidentified OF ranged from 53-100% in a majority of the samples. In addition the study was able to confirm the presence of fluorinated compounds other than those declared on the product labels.

The results suggest cosmetic products as a possible contributing source to total PFAS exposure, making their presence a possible concern to human health. Further studies are required to assess the risk.
