Table 2: Results on the detection of alkylphenol ethoxylates (APEOs), formaldehyde, aromatic amines derived from azo dyes, perfluorinated carboxylic acids, chlorophenols (PCPs), tetrachlor (TPCs), and phthalates in samples. “Neg” indicates no compound has been found. When found (“Pos”) the identified compounds are reported. ethyl-Aniline, and 2,4-Xylidine. These are present in 100% cotton samples made in China, such as \"tess_96\" and \"tess_97\", \"canov_blu\", and \"camicia\". Phthalates are esters of phthal acid. These molecules are primarily used in the plastics industry as plasticizers; however, they are also found in printing inks, adhesives, and rubber. They are added to the polymer to increase flexibility and elasticity. Phthalates DEHP and DBP (bis(2-ethylhexyl) phthalate and dibutyl phthalate) have been classified in Europe as toxic to reproduction, and their use has been largely restricted. The REACH regulation sets the limit for phthalates at <1 mg/kg. The presence of phthalates was detected in almost all samples. The molecule isobutylphthalate from the phthalate class is the most present. Chlorophenols (PCPs), tetrachlorophenols (TPCs), and their salts primarily come from use as antimicrobial and antifungal agents in treatments for natural fibers or for the protection of textile products during storage and transport. Some chlorophenols are used in the textile industry to prevent bad odors caused by bacteria from sweating in socks, shoes, and sportswear. According to European regulations and REACH, they may only be present in trace amounts in the finished product (<0.05 mg/kg). Although PCP is typically more commonly detected in fabrics made from natural fibers, it was not found in the 100% cotton samples analyzed. However, 2-chlorophenol from the PCP class was detected in \"calz_nr\" (made in Italy, 95% cotton, 5% elastane). Chlorobenzenes and chlorotoluenes (generally called carriers) may be present in polyester materials (as fiber-swelling agents), and as impurities in dyes, biocides, fumigants, and pesticides. They are extremely toxic to aquatic systems and cause skin and respiratory tract irritation. A great alternative to using chlorobenzenes and chlorotoluenes is the use of benzyl benzoate. They are not classified as potentially toxic substances in the REACH regulation, so no maximum legal concentration limit has been established. In the samples analyzed, this compound has not been detected.
