US Patent:

20050176598, Aug 11, 2005

Filed:

Jan 19, 2005

Appl. No.:

11/038296

Inventors:

Catharine Bergquist - Woodbridge NJ, US
Daniel Stauffer - Lawrenceville NJ, US
Paul Ferm - Morristown NJ, US

International Classification:

C11D003/50

US Classification:

510101000

Abstract:

The present invention relates to a controlled delivery system that can be incorporated in liquid, as well as, dry granular, or powder, household products, such as dishwashing detergents, surface cleaners, deodorizers, animal litters and cleaning wipes The system also prolongs the release rate of the active agents over an extended period of time, or provides heat triggered release of the active agents and yields a high impact fragrance “burst” upon heat treatment. The controlled delivery system of the present invention is a nano-sphere, having an average sphere diameter of from about 0.01 microns to about 10 microns. The nano-sphere comprises hydrophobic materials, cationic conditioning agent or, cationic conditioning agent in conjunction with a cationic charge booster to assist in adhering the spheres onto a surface.

Abstract:

The present invention relates to a controlled delivery system that can be incorporated in liquid, as well as, dry granular, or powder, household products, such as dishwashing detergents, surface cleaners, deodorizers, animal litters and cleaning wipes The controlled delivery system of the present invention is a solid, substantially spherical particle comprising a hydrophobic material. The particles can include cationic charge enhancing agents. The particles can also include a fragrance. The particle can have an average particle diameter of from about 1 micron to about 500 microns. The controlled delivery system of the present invention can be utilized to deliver a broad range of fragrance ingredients and prolong fragrance release over an extended period of time. The invention also pertains to household products comprising the controlled release system of the present invention.

US Classification:

524272

Abstract:

Hot melt adhesive compositions consisting essentially of: a) 15 to 45% by weight of at least one ethylene n-butyl acrylate copolymer containing 15 to 40% by weight n-butyl acrylate and having a melt index of at least 600; b) 25 to 55% of a terpene phenolic tackifying resin or a hydrogenated derivative thereof, the resin having a Ring and Ball softening point less than 125. degree. C. ; c) 15 to 40% by weight of a low melting point synthetic Fischer-Tropsch wax; and d) 0 to 1. 5% stabilizer. The adhesives are characterized by an excellent balance of high and low temperature performance without sacrifice to machinability or thermal stability.
