Patent number: 6221826Abstract: A laundry additive particle having multiple coatings and compositions employing the particle are provided. The laundry additive particle comprises a central core particle with the core particle comprising a porous carrier core material and a glassy encapsulating material intermixed with the carrier material. The glassy encapsulating material is derived from one or more at least partially water-soluble hydroxylic compounds having an anhydrous, nonplasticized, glass transition temperature, Tg, of at least about 0° C. An optional intermediate encapsulating material may be coated on the central core particle. The intermediate encapsulating material may comprise a carbohydrate material having an anhydrous nonplasticized, glass transition temperature, Tg of at least about 130° C. Lastly, an external coating material is coated on the core particle or the intermediate encapsulating material which provides the laundry additive particle with a substantially non-tacky surface.Type: GrantFiled: September 20, 1999Date of Patent: April 24, 2001Assignee: The Procter & Gamble CompanyInventors: Athanasios Surutzidis, Brent Michael Heist, Michael Jude LeBlanc

Patent number: 6025319Abstract: A laundry additive particle having multiple coatings and compositions employing the particle are provided. The laundry additive particle comprises a porous carrier core material; a first encapsulating material coated on the core material to form an intermediate layer, the first encapsulating material comprising a glassy material derived from one or more at least partially water-soluble hydroxylic compounds having an anhydrous, nonplasticized, glass transition temperature, T.sub.g, of at least about 0.degree. C.; and a second encapsulating material coated on the intermediate layer to form an outer layer, the second encapsulating material comprising a carbohydrate material having an anhydrous, nonplasticized, glass transition temperature, T.sub.g, of at least about 130.degree.0 C.; and the laundry additive particle has a hygroscopicity value of less than about 80%. Preferably, a laundry or cleaning agent such as a perfume is supported on or contained in the porous carrier.Type: GrantFiled: September 18, 1998Date of Patent: February 15, 2000Assignee: Procter & Gamble CompanyInventors: Athanasios Surutzidis, Michael J. LeBlanc

Patent number: 5858959Abstract: Glassy particles containing agents useful for laundry and cleaning products (preferably perfumes, bleaching agents, soil release polymers), and laundry and cleaning products containing these glassy particles. The particles comprise a glass derived from one or more at least partially water-soluble hydroxylic compounds, such as hydrogenated starch hydrolysates, sucrose, glucose, and starch hydrolysates. The glassy particle also has a hygroscopicity value of less than about 80%.Type: GrantFiled: August 29, 1997Date of Patent: January 12, 1999Assignee: Procter & Gamble CompanyInventors: Athanasios Surutzidis, Michael Jude LeBlanc

Patent number: 5830841Abstract: A process for preparing a suds controlling composition suitable for incorporation into laundry detergent products comprises absorbing into the pores of porous silica a sufficient amount of a surfactant-containing solution to ensure wetting of the porous silica, dispersing the porous silica having the surfactant-containing solution absorbed therein in a silicone oil and mixing the dispersion with a dispersing agent.Type: GrantFiled: December 2, 1996Date of Patent: November 3, 1998Assignee: The Procter & Gamble CompanyInventors: Athanasios Surutzidis, Roger Jeffery Jones
-
Patent number: 5668095Abstract: Detergent compositions are described which comprise a suds suppressing system consisting of a mixture of a silicone oil and a 2-alkyl-alcanol, or mixtures thereof.Type: GrantFiled: July 13, 1995Date of Patent: September 16, 1997Assignee: The Procter & Gamble CompanyInventors: Athanasios Surutzidis, Andrew Albon Fisk
-
Patent number: 5648327Abstract: Disclosed are aqueous liquid detergent compositions comprising dispersed particles of a silicone-based suds suppressor system and a separately added moderately hydrophobic particulate silica stabilizing agent. Such a separately added stabilizing agent serves to retard coalescence and coagulation of the suds suppressor particles and thus enhances the storage stability of the suds suppressor-containing detergent compositions of this invention.Type: GrantFiled: May 4, 1995Date of Patent: July 15, 1997Assignee: The Procter & Gamble CompanyInventors: Mark A. Smerznak, Roger J. Jones, Athanasios Surutzidis, Andrew A. Fisk, Steven P. Christiano, Gregory G. Bausch, Lauren M. Tonge, Sharon K. McCoy, Elizabeth F. Mallen

Patent number: 5648328Abstract: A process for producing a particulate laundry additive composition produces a particulate laundry additive for perfume delivery in laundry detergent compositions, especially those in the form of granules or agglomerates. The process includes mixing a porous carrier material, typically containing perfume, and an encapsulating material, typically a carbohydrate material, to form agglomerates or an extrudate which is then sized into particles for incorporation into a detergent product. The process may be employed to produce particulate additive compositions which may be used in fabric softening and dishwashing as well as laundry detergent compositions.Type: GrantFiled: February 6, 1996Date of Patent: July 15, 1997Assignee: The Procter & Gamble CompanyInventors: Adrian J. W. Angell, Athanasios Surutzidis, Frank A. Kvietok, David F. Perkis
