Cotton is used for the production of textiles, hygiene and cosmetic materials. During cultivation and technological processes, various types of substances (surfactants, softeners, lubricants, etc.) penetrate cotton, which can have a harmful effect on both the human body and the environment. The aim of this study was to analyze selected cotton products in order to identify the substances contained and to describe the potential possibilities of inducing textile contact dermatitis (CD). The impact of the identified compounds on the aquatic environment was also taken into account. Nine samples of cotton clothing and seven samples of cotton pads from various manufacturers were tested. Samples after extraction using the FUSLE (Focused Ultrasonic Liquid Extraction) technique were analyzed with GC/MS. Qualitative analysis was based on comparing mass spectra with library spectra using the following mass spectra deconvolution programs: MassHunter (Agilent), AMDIS (NIST), and PARADISE (University of Copenhagen). The parameter confirming the identification of the substance was the retention index. Through the non-target screening process, a total of 36 substances were identified, with an average AMDIS match factor of approximately 900 ("excellent match"). Analyzing the properties of the identified compounds, it can be concluded that most of them have potential properties that can cause CD, also due to the relatively high content in samples. This applies primarily to long-chain alkanes (C25-C31), saturated fatty acids, fatty alcohols (e.g., oleyl alcohol), and fatty acid amides (e.g., oleamide). However, there are not many reports describing cases of cotton CD. Information on the identified groups of compounds may be helpful in the case of unexplained sources of sensitization when the skin comes into contact with cotton materials. Some of the identified compounds are also classified as dangerous for aquatic organisms, especially if they can be released during laundering.
棉花用于生产纺织品、卫生和化妆品材料。在种植和加工过程中，各种物质（表面活性剂、柔软剂、润滑剂等）会渗透到棉花中，这些物质可能对人体和环境都有有害影响。本研究的目的是分析选定的棉制品，以确定其中所含的物质，并描述可能引起纺织物接触性皮炎（CD）的潜在可能性。还考虑了所识别的化合物对水生环境的影响。测试了来自不同制造商的九件棉制衣物和七件棉垫样品。使用 FUSLE（聚焦超声液体萃取）技术提取样品后，使用 GC/MS 进行分析。定性分析基于使用以下质谱解卷积程序将质谱与库谱进行比较：MassHunter（Agilent）、AMDIS（NIST）和 PARADISE（哥本哈根大学）。确认物质识别的参数是保留指数。通过非靶向筛选过程，总共鉴定了 36 种物质，AMDIS 匹配因子的平均值约为 900（“极好匹配”）。分析所鉴定化合物的性质，可以得出结论，大多数化合物具有引起 CD 的潜在特性，这也是由于样品中相对较高的含量。这主要适用于长链烷烃（C25-C31）、饱和脂肪酸、脂肪醇（例如油醇）和脂肪酸酰胺（例如油酰胺）。然而，描述棉 CD 的病例并不多。在皮肤接触棉制品时，如果无法解释致敏源，有关所鉴定化合物组的信息可能会有所帮助。所鉴定的一些化合物也被归类为对水生生物有危险的物质，特别是如果它们在洗涤过程中释放出来的话。
