ProTecht™ PAO is an odor absorption technology that is derived from castor seed. PAO’s raw material is naturally skilled at containing unwanted odors through adsorption. When the treated article is washed, it resets the adsorption capabilities. When a product is treated with PAO, a chemical bond is formed between the treated product and PAO. This allows for reliable and long-lasting durability. PAO is a sustainable functional finish certified by Oeko-Tex Eco Passport, ZDHC Level 3, Bluesign Approved and USDA BioPreferred.
