  • Patent number: 8663616
    Abstract: Disclosed herein are compositions and methods to treat an oral cavity surface with a peracid-based benefit agent. The peracid benefit agent can be use for oral surface bleaching, whitening, disinfecting, destaining, deodorizing, decreasing or removing biofilm, and combinations thereof. The peracid is enzymatically generated from a carboxylic acid ester substrate using a CE-7 carbohydrate esterase having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a peptidic component having affinity for an oral cavity surface, either directly or through an optional linker, may be used to target the perhydrolytic activity to the oral cavity surface.

  • Publication number: 20130171217
    Abstract: Disclosed herein are compositions and methods to treat skin with a peracid-based benefit agent. The peracid benefit agent can be used for a benefit such as the prevention or treatment of acne, skin whitening, skin bleaching, skin conditioning, reducing the appearance of skin wrinkles, skin rejuvenation, reducing dermal adhesions, and preventing, reducing or eliminating body odors or any combination thereof. The peracid may be enzymatically generated from a carboxylic acid ester substrate using an enzyme having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a skin-binding domain, either directly or through an optional linker, may be used to target the perhydrolytic activity to the skin surface.
