Patent number: 8815550Abstract: Disclosed herein are compositions and methods to target enzymatic peracid production to a target surface. The peracid benefit agent produced by the targeted perhydrolytic enzyme can be use for a variety of applications such as bleaching, whitening, disinfecting, destaining, deodorizing, and combinations thereof. Specifically, a fusion protein comprising a perhydrolytic enzyme and at least one peptidic component having affinity for a target surface (excluding body surfaces and oral care surfaces) is used in combination with a suitable substrate and a source of peroxygen to enzymatically produce a peracid on or near the surface of the target material. In a preferred aspect, the target surface is a cellulosic material.Type: GrantFiled: November 13, 2013Date of Patent: August 26, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Robert DiCosimo, Scott D Cunningham, Stephen R Fahnestock, Tanja Maria Gruber, Mark S Payne, Pierre E Rouviere, Linda Jane Solomon, Hong Wang

Patent number: 8663616Abstract: 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.Type: GrantFiled: December 19, 2011Date of Patent: March 4, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Lisa A. Butterick, Scott D. Cunningham, Robert DiCosimo, Kari A. Fosser, Tanja Maria Gruber, Sharon L. Haynie, Mark S. Payne, Pierre E. Rouviere, Hong Wang

Publication number: 20130171217Abstract: 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.Type: ApplicationFiled: June 14, 2012Publication date: July 4, 2013Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: DEXTER A.
