Aqueous Disinfectants and Sterilants

US Patent No. 7,935,667 B2; Solutions BioMed, LLC, Orem, UT, has patented an aqueous disinfectant or sterilant composition that is comprised of an aqueous vehicle, including water, peracid and a peroxide, wherein the peroxide includes a peroxyhydrate; as well as a colloidal transition metal or alloy thereof based on the aqueous vehicle content.


Hair Care Composition
US Patent No. 7,947,259 B2; Conopco, Inc., Englewood Cliffs, NJ, has patented a hair care composition in the form of an aqueous shampoo composition comprising anionic surfactants wherein the anionic surfactants are sodium lauryl sulfate and laureth-3-sulfosuccinate; amphoteric surfactant (cocoamidopropyl betaine); nonionic polymer of ethylene oxide wherein the nonionic polymer of ethylene oxide is PEG-180M; nonionic cellulose ether based wherein the nonionic cellulose ether is hydroxypropyl methyl cellulose with viscosity of 4,000 mPa·s; cationic polymer wherein the cationic polymer is guar hydroxypropyl trimethylammonium chloride; and conditioning agent wherein the conditioning agent is an emulsion of dimethiconol.

The compositions comprising both nonionic polymer of ethylene oxide and nonionic cellulose ether have enhanced wet slippery feel and ease of rinse compared to use of identical composition where only one of the two nonionic polymers is used.


SC Johnson Patents Stain Neutralizer
US Patent No. 7,947,640 B2; S.C. Johnson & Son, Inc., Racine, WI, has patented a method of neutralizing a stain on a surface. It entails applying a first effective amount of a composition to a stain on a selected surface to affect a color change thereon, the composition comprising a liquid carrier and particles, the particles comprising a homogeneous mixture of a first additive and at least one polymer selected from the group consisting of a polyolefin, a polyurethane, an acrylic, an acrylate, a polyamine, a polyamide, a polyamid, a polyimide, a polyether, a polystyrene, a polycarbonate, polysulfone, a polyester, a polyalkyleneoxide, a polysiloxane, a polysulfide, a polyethyleneimine, a cellulose, a wax, a paraffin, a phenolic, an elastomer, a vinyl, a hot melt adhesive, a hydrophilic polycarbodiimide, a polysaccharide aldehyde derivative, a bismaleimides, a silicon, a soya oil, a linseed oil modified alkyd, a copolymer, a homopolymer, and mixtures thereof. The composition is then allowed to dry on the surface to attach the particles to the surface, neutralizing the stain on the surface by removing the attached particles from the surface. After removing the attached particles from the surface, if a residual stain material remains on the surface, masking the residual stain material on the surface by applying a second effective amount of the composition to the residual stain material and applying heat or a chemical to the second effective amount of the composition to durably affix the composition to the surface.


Spray-Drying Process For Detergent Powder
US Patent No. 7,947,642 B2; Procter & Gamble has patented a spray-drying process for preparing a spray-dried detergent powder having a bulk density of approximately 50-325g/l. It is comprised of preparing an aqueous slurry suitable for spray-drying comprising water and non-aqueous material comprised an anionic surfactant, a polymeric carboxylate and a carbonate salt; and spraying the slurry into a spray-drying tower. The spray-dried detergent powder is essentially free from zeolite and silicate salt.


Dryer Sheets Patented By Wausau Paper Mills
US Patent No. 7,947,644 B2; Wausau Paper Mills, Mosinee, WI, has patented a single-ply dryer sheet that is comprised of a nonwoven substrate that is made of a mixture of wood fiber and regenerated cellulose fiber and a fabric conditioning agent provided on the nonwoven substrate. At least a portion of the fabric conditioning agent transfers from the nonwoven substrate to the laundry once the temperature within the tumble-type dryer is greater than approximately 120°F.


Reducing Malodor In Permanently Waved Hair
US Patent No. US 7,955,593 B2; Zotos International, Inc., Darien, CT, has patented an odor-reducing post treatment composition for application to permanently waved hair immediately after removal of a neutralizer. The composition consists of a hair fixative agent comprising polyquaternium-7, a conditioning agent comprising dimethicone and tallow trimonium chloride, a hair strengthening complex comprising hydrolyzed vegetable protein PG-propyl silaneriol, a fragrance blend (wherein the fragrance blend comprises 4 methyl-4-(methylthio)-2-pentanone, at least one component having a log P ranging between about 1 and 3, and at least two components having a log P greater than 4.0), chelating agent, anti-static agent, preservative, solubilizer and water.


New Antimicrobial Composition
US Patent No. 7,955,610 B2; A US patent has been awarded to the National Science and Technology Development Agency, Prathumthani; and Nonami Science (Thailand) Co., Ltd., Bangkok, Thailand, for a topical antimicrobial composition. It is comprised of a photocatalyst mixture containing titanium dioxide, sodium perborate, magnesium silicate and citric acid; a pharmaceutically acceptable carrier; and a pH range from 4-6. The composition is effective as an antimicrobial under visible light.
