摘要:
Disclosed herein is a method for stabilization of the perhydrolase activity of the CE-7 esterase in a formulation with a carboxylic acid ester that employs the addition of a buffering agent, substantially undissolved, to the mixture of the CE-7 esterase and the carboxylic acid ester. Further, disinfectant and laundry care formulations comprising the peracids produced by the processes described herein are provided.
摘要:
Aqueous, thickened, acidic compositions which exhibit a pH of about 7 or less preferably 5 or less, and comprise an organic acid constituent selected from formic acid, citric acid and oxalic acid, a thickening constituent or constituents based on one or more gums, particularly xanthan gum which form a thickener system in the inventive composition, and at least one detersive surfactant based on glycoside surfactants, water in an amount of at least 85% wt., preferably at least about 90% wt., and one or more further optional constituents, wherein the compositions exclude: (a) surfactant compounds which include a nitrogen atom in the surfactant compound, and (b) inorganic acids.
摘要:
A detergent for cleaning fins of a condenser/radiator/evaporator has a composition including a surfactant of 0.1%˜55% by weight, an acid substance of 0.1˜50% by weight, and water. The surfactant is made from a halogen or a halide polymerized in an epoxide, and then neutralized with an alkaline substance. The surfactant reacts with the chemical substance of the dirt to remove the dirt from the fins. The acid substance may speed up the reaction. Thus, the detergent of the present invention still may clean the fins in an environment of pH5.0, which is close to the pH value of skin.
摘要:
A multi-surface bathroom cleaning system is described that allows for easier cleaning of all bathroom surfaces from all angles, especially under the rim of a toilet bowl, and which comprises an acid/nonionic composition contained in and dispensable from a package comprising an angled-neck sprayer bottle fitted with an invertible trigger sprayer assembly, wherein the cleaning system may be used in an entirely upside-down orientation to spray upwards at an acute angle.
摘要:
The invention relates to bleach catalysts containing a manganese compound and oxalic acid, or the salt or derivatives thereof. The presence of the oxalic acid reinforces the action of the manganese compound as a bleach catalyst.
摘要:
The present invention is directed, in certain embodiments, to compositions useful for the removal of grease, lime scale, soap scum, feces, rust or other soils from surfaces such as those found in bathrooms, toilets and kitchens. Methods of removing soils and preventing soil adhesion are also contemplated.
摘要:
Disclosed herein are multi-component formulations for enzymatically producing aqueous solutions of peroxycarboxylic acids suitable for use in, e.g., disinfectant and/or bleaching applications. The multi-component peroxycarboxylic acid formulations comprise at least one carbohydrate esterase family 7 enzyme having perhydrolytic activity.
摘要:
The present invention relates to a method for making starch encapsulated ingredients where a mixture of starch, water, acid and ingredient for encapsulation is prepared. The mixture is atomised and dried to provide encapsulates that can retain high levels of encapsulated ingredient. When the encapsulated ingredient comprises oil, the invention reduces the levels of free oil on the outside of the encapsulates and surprisingly reduces explosivity of fines produced during the manufacturing process. The preferred acid is citric acid.
摘要:
A fabric conditioner composition comprising: (g) 0.1-20% by weight cationic fabric conditioner active; (h) 0.1-5% by weight anion quencher selected from mono-long chain quaternary ammonium compound of the general formula R(R1)3N+X- or alkyl benzyl quaternary ammonium compound of a general formula R2R3(R4)2N+X-; (i) 0.1-10% by weight organic acid having from 1 to 8 carbon atoms; where R is selected from C8-C22 alkyl or alkenyl group, R1 is selected from C1-C3 alkyl group, R2 is selected from C6-C18 alkyl or alkenyl group, R3 is benzyl group, R4 is selected from C1-C3 alkyl group, and X is an anion selected from chloride, bromide, iodide, nitrate, sulfate, methyl sulfate, ethyl sulfate, acetate and phosphate.
摘要:
A composition comprising a mixing product of: (i) a first acid having a pKa of less than 3, in an amount by weight of 1-10%, (ii) a second acid having a pKa of greater than 3, in an amount by weight of 1-10%, (iii) a nonionic surfactant in an amount by weight of 1-7%; and (iv) water; wherein the composition has a pH of less than 2.5. The composition can be used for the removal of grease, lime scale, soap scum, and rust on hard surfaces.
