摘要:
A stable fluid polymer suspension is composed of at least one water soluble polysaccharide polymer in an aqueous carrier fluid in which the polysaccharide polymer does not significantly swell or dissolve where the polysaccharide polymer in the aqueous carrier fluid has the measured properties of:i) rendering the polymer(s) insoluble, resulting in a cloudy dispersion,ii) limiting the swelling of insolubilized polymer(s), leading to a polymer sediment volume of a 1 weight percent polymer dispersion to less than 1%, andiii) preventing phase separation for at least one week.This invention also Includes a method of preparing the stable fluid polymer suspension having the above mentioned measured properties. The stable aqueous fluid suspension of this invention is a clear, odorless, and stable formulation and is used in cosmetics, personal care, and household products.
摘要:
The present invention concerns the use of depolymerized carboxylated celluloses as a dispersing agent or grinding aid agent for aqueous suspensions of mineral materials, intended for paint formulations, plastic formulations, detergent formulations, cosmetic formulations, paper formulations or paper coating colors.
摘要:
Water-based silicone resin emulsions are provided comprising an organopolysiloxane resin or mixture of resins which may include a solvent carrier, and a combination of emulsifying agents including cellulosic-type and anionic surfactant-type emulsifiers as well as an amount of water sufficient for providing a water-based emulsion having a desired viscosity and silicone resin solids content by weight.
摘要:
There is disclosed an aqueous suspension vehicle consisting essentially of water having dissolved therein a water-soluble suspending agent, such as one or more hydroxyethylcelluloses, in a concentration below about 0.4 weight percent, and about 0.01 to about 0.5 percent of a water-soluble organic solvent for said suspending agent, such as dimethylformamide.
摘要:
Surfactant systems are provided using microfibrous cellulose to suspend particulates. In one embodiment the surfactant system includes a microfibrous cellulose at a concentration from about 0.05% to about 1.0% (w/w), a surfactant at a concentration of about 51% to about 99% (w/w active surfactant), and a suspended particulate. Also provided herein are methods for preparing surfactant systems including microfibrous cellulose.
摘要:
The invention relates to water-soluble sulfoethyl cellulose ethers, more particularly methyl sulfoethyl cellulose ether (MSEC), of very high solution quality, to a process for its production and to the use of these products as thickeners, dispersants or binders.
摘要:
An edible suspension of a finely divided food material in a liquid suspending medium which swells cellulose, the suspension also containing microfibrillated cellulose in an amount sufficient to produce a stable, homogeneous suspension. The microfibrillated cellulose, a form of cellulose having a very large available surface area per unit of weight, acts to confer, among other benefits, greater stability on the suspension.
摘要:
Insulating materials consisting of artifical mineral fibers are impregnated with water insoluble additives, e.g. dust binders and/or water repellant finishing agents in that they are wetted with an emulsion of the water insoluble additive in an aqueous solution of a cellulose ether. Impregnation takes place easily and is effective and resistant.
摘要:
An aqueous organosilicon composition is prepared by mixing water with an organopolysiloxane having at least one ##STR1## group and having aliphatic radicals which are bonded to silicon via oxygen, a polyvinyl alcohol and/or a water-soluble cellulose ether containing hydroxyl groups in the presence of sufficient acid to provide a composition having an acid pH. The resultant composition may be neutralized and used as additives in aqueous paint compositions.
摘要:
A cellular elastomeric product is prepared by the curing of a froth prepared by whipping air into an aqueous dispersion of colloidal elastomer, said aqueous dispersion containing a latex frothing agent consisting of an aqueous solution containing about 70% water and about 25% magnesium di(lauryl sulfate), about 2.5% polyalkoxyglycerol having about eight alkoxy groups per hydroxyl and about 2.5% of a quaternary, dihydroimidazole derivative, there being a fatty acid carbon chain attached as the only carbon-carbon linkage for the carbon between the two nitrogens of the imidazole ring, the quaternary nitrogen partaking of the nature of a quaternary sodium glycinate having at such quaternary nitrogen both an alkhydroxy group and said dihydroimidazole ring.
