Abstract
There is provided a method of delivering a benefit agent whereby a benefit agent is first loaded to a surface and subsequently unloaded and transferred and delivered to a second surface. More in particular, the benefit agent is first loaded onto a garment during a laundering process, and subsequently delivered to another surface. The benefit agents can be fragrance agents, perfumes, colour enhancers, fabric softening agents, polymeric lubricants, photoprotective agents, latexes, resins, dye fixative agents, encapsulated materials, antioxidants, insecticides, soil repelling agents, soil release agents, and cellulose fibers.
Claims24
A method of delivering a benefit agent whereby a benefit agent is loaded to a first surface by contacting the first surface with a binding molecule carrying the benefit agent and subsequently unloaded and transferred and delivered to a second surface wherein said binding molecule is selected from the group consisting of an antibody, an antibody fragment and a derivative thereof.
A method of delivering a benefit agent whereby a benefit agent is loaded to a first surface by contacting the first surface with a binding molecule carrying the benefit agent and subsequently unloaded and transferred and delivered to a second surface wherein said binding molecule is a fusion protein comprising a cellulose binding domain and a domain having a high binding affinity to another ligand.
A method of delivering a benefit agent whereby a benefit agent is loaded to a first surface by contacting the first surface with a binding molecule carrying the benefit agent and subsequently unloaded and transferred and delivered to a second surface wherein said benefit agent is an enzyme or enzyme part capable of catalyzing the formation of a bleaching agent.
A method of delivering a benefit agent whereby a benefit agent is loaded to a first surface by contacting the first surface with a binding molecule carrying the benefit agent and subsequently unloaded and transferred and delivered to a second surface wherein said benefit agent is selected from the group consisting of glucose oxidase, galactose oxidase alcohol oxidase and chloroperoxidase.
A method of delivering a benefit agent whereby a benefit agent is loaded to a first surface by contacting the first surface with a binding molecule carrying the benefit agent and subsequently unloaded and transferred and delivered to a second surface wherein second surface is selected from the group consisting of fabric skin, and a ligand.
A method of delivering a benefit agent whereby a benefit agent is loaded to a first surface by contacting the first surface with a binding molecule carrying the benefit agent and subsequently unloaded and transferred and delivered to a second surface wherein the binding molecule has a chemical equilibrium constant Kd for the first surface of less than 10−4 M.
