Toxic PFAS not necessary to make fabric stain repellent, study finds

Research found that forever chemicals' had no practical benefit' in repelling water and stains as compared with untreated fabric

Most water and stain repellents applied to fabrics worldwide use toxic PFAS as a main ingredient, and though the controversial chemicals are in thousands of products, water and stain repellency are two of their main consumer functions.
