  • Patent number: 6989339
    Abstract: The present invention describes a means for fixing skin care ingredients on the surface of non-woven webs and cellulosic mats. The active ingredients can be released (deposited) onto the skin by normal triggering mechanisms, which include the action of water or urine or by friction or rubbing. The fixative systems described herein provide the ability to control high load levels while not interfering with the wettabliity of the fabric or paper. Additionally, incompatible/reactive ingredients can be treated onto the same web and are kept as separate particles fixed to the surface until released.

  • Patent number: 6921820
    Abstract: A method for forming II-type cellulose, which comprises introducing together a slurry having water and a I-type cellulose dispersed therein and water in the state of high temperature and high pressure to a tubular reactor (28) contacting the I-type cellulose with a hot water in a supercritical state or subcritical state for a predetermined time in the tubular reactor (28), to thereby cleave a part of the hydrogen bonds in the I-type cellulose and dissolve the I-type cellulose into the water in a supercritical state or subcritical state, cooling a cellulose solution discharged from the tubular reactor (28) in a cooler (30) to room temperature or lower, followed by allowing to stand, to thereby precipitate crystals of II-type cellulose having a molecular weight lower than that of the I-type cellulose, and separating the resultant II-type cellulose from a solvent. The method allows the preparation of pure II-type cellulose by the use of a simple process.

  • Publication number: 20040237839
    Abstract: The present invention relates to compositions of starch. The compositions consist of an anionic and a cationic starch wherein at least one of the starches is waxy. The compositions are surprisingly not resulting in an agglomerated product when cooked. The compositions are used in paper or cardboard preparation. The compositions are cooked and added at the wet end of the paper production process. This results in a high possible addition level and the use of the size press is abolished. The resulting paper and board are shown to have better characteristics than the paper and board prepared with the same components which have not been mixed prior to addition but which are added separately.

  • Patent number: 6589328
    Abstract: The invention provides sponges (foams) produced from hydrocolloids by the expansion of gels of these. The foams have properties which can be varied, such as water absorption, biodegradibility, pore size and structure. Edible products can be produced which may contain an edible plasticizer, a sugar or sugar substitute and possibly also a flavoring agent or taste enhancer. The novel sponges are produced by preparing a gel of a hydrocolloid, and either sealing it in a closed vessel with a liquid of similar composition, pressurizing the vessel and abruptly releasing the pressure, followed by freeze drying, or by incorporating in such a gel a suitable microorganism, such as a yeast and inducing fermentation in the presence of a suitable nutrient medium, so that the carbon dioxide formed results in the expansion and foam formation, which is processed to the final product. The sponges-foams of the invention are such, that the initial network of the gel is maintained.

  • Patent number: 6379447
    Abstract: An aqueous, light weight paper laminating adhesive comprising a continuous aqueous phase of from about 15 to 50% by weight of polysaccharide material dispersed in water, the continuous phase polysaccharide material having a zero-shear viscosity of greater than 0.07 Pa·s when measured at 26% (+/−1% solids) and a shear rate of 0.1s−1; a shear-thinning index of 0.90 to 1.1; and bleed time of greater than 15 seconds. Also disclosed is another adhesive composition, which is particularly useful in non-contact spay applications and comprises the continuous phase polysaccharide phase described above as well as a second component comprising a water swellable, insoluble polysaccharide particulate phase.

  • Patent number: 6306218
    Abstract: A method of producing starch-emulsifier compositions by heating a starch in the presence of an emulsifier to form a complex with unique properties. The product can be further treated to obtain greater than about 20% short chain amylose. Starch-emulsifier compositions (e.g., powders, gels, pastes) produced by this method and food products containing the starch-emulsifier composition are also described.

  • Patent number: 6231970
    Abstract: Thermoplastic starch compositions that include a particulate filler, e.g. an inorganic filler component, and optional fibrous component The compositions include a thermoplastic phase comprising a thermoplastic starch melt that contains, at a minimum, starch blended with an appropriate plasticizing agent under conditions in order for the starch to form a thermoplastic melt. The thermoplastic phase may also include one or more additional thermoplastic polymers and other optional reactants, liquids or cross-linking agents to improve the water-resistance, strength, and/or other mechanical properties of the thermoplastic melt, particularly upon solidification. The inorganic filler component may affect the mechanical properties but will mainly be added to reduce the cost of the thermoplastic starch compositions by displacing a significant portion of the more expensive starch or starch/polymer melt.
