Microbiological Properties

Polymeric products enriched with natural additives e.g. hyaluronic acid, plant hydrolates or collagen may find a wide application avenue due to the ever-growing demand for natural cosmetics. The ecology of cosmetics is equally important. Therefore, in the work presented a biodegradable nonwoven was prepared with natural components as an active layer for cosmetic application. Synthesied was the biodegradable aliphatic-aromatic copolyester: poly (1.4 butylene succinate-co-glutarate-co-adipate-co-terephtalate). suitable for the forming of spunbond nonwoven. The active layer was deposited by padding on basic nonwoven. Assessed were microbiological and mechanical properties as well as the in- compost decomposition of the product. Activity against S. aureus and E. coli was tested and microbiological purity estimated. The best serviceable composition of the active layer was selected based on the microbiological properties tested. It contains sodium hialuronate, plant hydrolate of the bitter orange (Neroli), and collagen. Thanks to good mechanical properties, nonwoven made of aliphatic-aromatic co-polyester may serve as a carrier of the cosmetic layer in applications like face masks.
