Abstract
Disclosed is an aqueous coating composition including at least one latex polymer derived from at least one monomer copolymerized or blended with a rhamnolipid and/or sophorolipid biosurfactant. Also provided is an aqueous architectural coating composition including at least one latex polymer derived from at least one monomer copolymerized or blended with a rhamnolipid and/or sophorolipid biosurfactant, at least one pigment, and water. Also provided is a method of preparing an aqueous architectural coating composition such as a latex paint including the above components.
Claims33
An aqueous coating composition, comprising a dispersion comprising
- (a) at least one latex polymer binder;
- (b) a biocide effective amount of at least one biocide comprising at least one biosurfactant selected from the group consisting of rhamnolipids and sophorolipids;
- and
- (c) water.
A process for using a biosurfactant for polymerization, comprising the step of emulsion polymerizing a reaction mixture to prepare a latex polymer binder, said reaction mixture comprising at least one monomer and at least one biosurfactant selected from the group consisting of rhamnolipids and sophorolipids.
(canceled)
A method of preparing an aqueous architectural coating composition, comprising mixing at least one latex polymer binder aqueous dispersion with a biocide and/or mildewcide effective amount of at least one biocide comprising at least one biosurfactant selected from the group consisting of rhamnolipids and sophorolipids in the presence of water.
