With the preservative methylisothiazolinone under regulatory pressure due to its skin-sensitizing potential, and consumers increasinglyWith the preservative methylisothiazolinone under regulatory pressure due to its skin-sensitizing potential, and consumers increasinglylooking for home care products that are both human- and environmentally friendly, formulators are searching foralternatives to isothiazolinones to preserve home care products. Sorbates have a long history of safe use in food, pharmaceuticaland personal care applications. They are considered nature identical and are ecolabel compliant. As biocidal products, underthe applicable Biocidal Product Regulation (EU) 528/2012 (BPR), Nutrinova® Potassium Sorbate BFX Granules and Nutrinova®Sorbic Acid BFX DF have now been made available for home care formulations by Celanese, the only western manufacturer ofpotassium sorbate and sorbic acid.Their efficacy at use levels of 0.1-0.4%, both bactericidal and fungicidal, is demonstrated in a range of home care detergentformulations, such as manual dishwashing liquids, fabric conditioners and all-purpose cleaners. Their viability as a possible efficaciousalternative to isothiazolinones in such formulations is thus supported.
