摘要:
An aqueous laundry prewash composition includes a cosurfactant system with a hydrophobic nonionic surfactant and a hydrophilic nonionic surfactant providing balanced detergency, a hydrotrope for stabilizing the cosurfactant system, a thickener and water forming the balance of the composition. A thickened aqueous laundry prewash composition is also disclosed including a surfactant system, water and a thickener being xanthan gum to develop a pourable product wherein shear caused by dispensing of the composition tends to reduce its viscosity. An aqueous laundry prewash composition thickened in a similar manner maintains in suspension an insoluble particle component to further enhance prewash characteristics.
摘要:
A method for the detection and/or determination of an antigen having at least two separate antibody combining sites or antigenic determinants (i.e. a polyvalent antigen) using at least two different monoclonal antibodies which bind to the separate sites is described. In particular the method utilizes Protein A with a carrier to immobilize a first monoclonal antibody which in turn, can bind to one antigenic determinant on the antigen. The second antibody with a label is provided in a solution and binds to the second antigenic determinant on the antigen. A test kit is described for practicing the method. Novel anti-PGH synthase and anti-PGI.sub.2 synthase antibodies and hybridoma cells producing such antibodies are described.
摘要:
The title compositions impart fire retardancy to and are not readily leached from various cellulosic substrates. For example, wood treated with a composition comprising a phosphate salt of poly(2-ethyl-2-oxazoline) and a 40:60 mixture of mono- and diammonium phosphate is not only rendered fire retardant but the phosphates exhibit good resistance to leaching.

The present invention provides a method of using a solid-layered composition having at least two parts. The first past comprises a) calcium hypochlorite, magnesium hypochlorite and mixtures thereof, b) a builder, c) a water-soluble polymer, d) an acid, and e) wherein the first part does not contain sodium hypochlorite, lithium hypochlorite, potassium hypochlorite and mixtures thereof. The second part comprises a) a surfactant, b) a builder, c) an acid, and d) wherein the second part does not contain any oxidant.
摘要:
Methods for introducing a substantially uniform concentration of a functional agent into a flowing stream of water using a shaped composition. The composition may be shaped and sized to be inserted into a device configured to be attached over the end of a faucet. The shaped composition comprises a dissolvable region including a functional agent (e.g., an anti-microbial sanitizing agent). A non-dissolvable region disposed adjacent to the dissolvable region may optionally be provided. The substantially non-dissolvable region remains substantially intact as the dissolving region is progressively dissolved, introducing the functional agent into a flowing stream of water.

A cleaning substrate which comprises at least one layer of a solid hypohalite precipitate, wherein the hypohalite precipitate is formed in situ on the layer of substrate material. A process for making a fibrous cleaning substrate comprising the steps of: a) providing at least one layer of fibrous material; b) exposing the fibrous layer to an aqueous alkaline earth salt solution; c) treating the fibrous layer with a hypochlorite solution; d) allowing the aqueous alkaline earth salt solution combine with the hypochlorite solution to form a solid hypochlorite precipitate around the fibers in the fibrous material and a liquid phase, and e) removing at least 65% of the liquid phase from the fibrous substrate.
摘要:
Systems and methods for performing a self-test on a sensing device are described in the present disclosure. One implementation, among others, includes a method of performing a self test. In this implementation, the method includes supplying a periodic magnetic field upon a sensing element that is configured to sense a parameter of an object. The method further includes receiving an output from the sensing element indicating the operability of the sensing element. It should be noted that the output is received independently of the parameter of the object.

摘要:
The invention provides an aqueous bleaching solution for substrate treatment comprising a source of oxidant and a suspended polymer matrix having a plurality of optically functional particles associated with one or more copolymers present in the polymer matrix. The plurality of optically functional particles are associated with the copolymer during polymerization of at least one hydrophobic and at least one hydrophilic monomer so as to form a polymer matrix useful to impart an aqueous bleaching solution with optically functional properties providing a benefit to the solutions during storage, use and application to substrates for treatment. In accordance with various embodiments of the invention, the suspended polymer matrix forms a substantially stable dispersion of the optically functional particles in the aqueous bleaching solution, and provides compositions, methods and kits for employing aqueous bleaching solutions having optically functional properties that are maintained over substantially long storage times.
