  • Publication number: 20070071874
    Abstract: This invention is directed toward cream compositions containing hydroxypropyl methylcellulose (HPMC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose(MHEC), methyl cellulose (MC) or ethyl cellulose (EC), and their blends with water-soluble or water-swellable hydrocolloids. The cream compositions are useful in both dairy and non-dairy product compositions. The cream composition can be subjected to thermal processing to produce packaged products which are shelf-stable. The cream compositions are also useful in producing whipped compositions which exhibit a desirable appearance and amount of overrun.

  • Publication number: 20060240159
    Abstract: A pasteurization or sterilization process reduces fouling of a food or beverage composition containing protein during the heat treatment. An antifouling agent is added to the food or beverage composition that is selected from hydroxypropylcellulose (HPC) with a hydroxypropyl molar substitution of greater than 3.0 and a weight average molecular weight (Mw) as measured by SEC of greater than 350,000 Dalton, methylhydroxypropylcellulose (MHPC) with a methoxyl content of greater than 17% and a hydroxypropyl content of greater than 3%, methylcellulose (MC) with a methoxyl content greater than 17% and a viscosity in water at ambient temperatures and a concentration of 2% of greater than 1,000 cps, or mixtures thereof, This food or beverage composition is then heated in a first heat exchanger at a temperature between 50 and 100° C. for a time of from about 2 seconds to 30 minutes for pasteurization or it is further heated to sterilization temperatures before being packaged out or further processed.

  • Patent number: 7067499
    Abstract: A composition of a cationic polygalactomannan or a derivative of cationic polygalactomannans is provided that has a mean average molecular weight (Mw) having a lower limit of 5,000 and an upper limit of 200,000 and has a light transmittance in a 10% aqueous solution of greater than 80% at a light wavelength of 600 nm and a protein content of less than 1.0% by weight of polysaccharide, and aldehyde functionality content of at least of 0.01 meq/gram. This composition is prepared in continuous or batch processes using either oxidizing reagents or combination of hydrolytic reagents and oxidizing reagents. This composition is used in personal care and household care products.

  • Publication number: 20060134047
    Abstract: A conditioning composition is used in functional systems (personal care and household care compositions) that has a nonionic hydrophobically modified cellulose ether (HMCE) having a weight average molecular weight (Mw) with a lower limit of 400,000 and an upper limit of 2,000,000 and a hydrophobic substitution lower limit of 0.6 wt % and an upper limit amount which renders said cellulose ether insoluble in a 5 wt % solution of surfactant and less than 0.05% by weight soluble in water and wherein the cellulose ether provides conditioning benefit to the functional system substrate. This composition has at least one active functional system ingredient.

  • Publication number: 20060046943
    Abstract: A reduced odor composition is composed of a functional system such as household care, personal care or pet care products and at least one cationic polygalactomannan or a derivative of cationic polygalactomannan having a cationic degree of substitution (DS) lower limit of about 0.01 and an upper limit of about 3.0 and weight average molecular weight (Mw) having a lower limit of 200,000 and an upper limit of 2,000,000 a concentration with a lower limit of 0.005 wt % and an upper limit of 10 wt %, and a trimethylamine content of less than 25 ppm, wherein the composition, at an alkaline pH, has no discernible amine odor.

  • Publication number: 20060045861
    Abstract: A reduced odor composition is composed of at least one cationic polygalactomannan or a derivative of cationic polygalactomannan having a weight average molecular weight (Mw) having a lower limit of 5,000 and an upper limit of 200,000, a light transmittance in a 10% aqueous solution of greater than 80% at a light wavelength of 600 nm, a protein content of less than 1.0% by weight of polysaccharide, and a trimethylamine content of less than 25 ppm in a 10% aqueous solution of the polymer. This composition is prepared by treating the polymer with reagents that reduce the molecular weight of the polymer, removing the water-insoluble solid material, and removing odorous components, including trimethylamine (TMA) and other amines and low molecular weight components from the aqueous phase to produce a polymer that when used in a functional system such as household care, personal care or pet care products has reduced or no odor at acidic, neutral, or alkaline pH values.

  • Publication number: 20050227902
    Abstract: A cationic, oxidized polysaccharide or derivative thereof that has a mean average molecular weight (Mw) having a lower limit of 50,000 and an upper limit of 1,000,000 and an aldehyde functionality content of at least 0.001 meq/gram is used in personal care and household care compositions. This cationic, oxidized polysaccharide is prepared in continuous or batch processes using hydrolytic reagents, oxidizing reagents, or combination of hydrolytic reagents and oxidizing reagents. Personal care or household care compositions are prepared by adding the cationic, oxidized polysaccharide to a personal care or household composition containing at least one active ingredient other than the cationic, oxidized polysaccharide of this invention.
