摘要:
A process for processing an alcohol-containing solvent is described. The process according to the invention is used in particular for the treatment of alcohol-containing solvents which are used, for example, for cleaning metal parts. Further subject matter of the present invention are compositions which are suitable for the aforementioned intended use, as well as the use of certain compositions for the purification of alcohol-containing solvents.
摘要:
The aim of the invention is to improve the primary detergent power of detergents and cleaning products, in particular with respect to soiling containing oil and/or grease. For this purpose, polymers comprising N-vinyl imidazole-derived betaine units are incorporated into the products.
摘要:
The present invention generally relates to methods of cleaning residual pesticide from an agricultural vessel, and to kits and compositions useful for the practice of such methods.
摘要:
A process for reducing the amount of halocarbons in a mixture containing water and at least one of an alkyl or alkenyl glycoside carboxylic acid. The amount of halocarbon is reduced by heating the mixture at a temperature of 50° C. to 120° C. at a pH of from 10-14. The amount of organomonochloro compounds can be reduced to a range of 5 ppm or less and the amount of organodichloro compounds can be reduced to a range of 30 ppm.
摘要:
A method for formulating a cleaning composition, wherein the cleaning composition comprises a water-soluble organic solvent, an ionic surfactant, a nonionic surfactant, a chelating agent, and distilled water.
摘要:
To provide an anionic surfactant powder comprising a polyoxyalkylene ether sulfate which powder has high stability in hard water, high low-temperature solubility and is improved in powder characteristics such as caking characteristics, and a method of producing the anionic surfactant powder. An anionic surfactant powder comprising polyoxyalkylene alkyl ether sulfates in which the average addition mol number of alkylene oxides is 0.05 to 2, wherein the content of the polyoxyalkylene alkyl ether sulfates provided with alkylene oxides added thereto in an amount of 4 mol or more is 30 % by weight or less based on the total anionic surfactant, an anionic surfactant powder further comprising a water-soluble inorganic salt, a method of producing each of these anionic surfactant powders, and a detergent composition and a cement additive comprising these anionic surfactant powders.
摘要:
The present invention describes easily soluble surfactant granulates containing builders, having a variable bulk weight and an excellent solubility profile, containing the neutralized from of an anionic surfactant acid and sodium carbonate and sodium hydrogencarbonate, produced by neutralization of mixtures of anionic surfactant acids and builder acids with solid neutralizing agents. The present invention provides a method for producing surfactant granulates, comprising providing a mixture of anionic surfactant acids and builder acids having a weight ratio of 1:500 to 50:1 of builder acid to surfactant acid and contacting the mixture with solid neutralizing agents.
摘要:
Anionic surfactant concentrates in the form of solid free-flowing powders and/or granules which may also be present as compounds in admixture with other auxiliaries and/or useful materials suitable for use in detergents and/or cleaning products and which have apparent densities of at least about 150 g/l are produced by hot drying of the water-containing preparations with superheated steam as the drying gas. Preferred apparent densities are above about 200 g/l and are preferably at least about 350 g/l. In addition, the pourable and free-flowing material is preferably in the form of a substantially dust-free material through the presence of dust-binding auxiliaries and/or useful materials and/or by regulation of the residual water content. In one preferred embodiment, the anionic surfactant concentrate is in the form of porous carrier beads with an absorbent porous inner structure.
摘要:
A detergent paste composition comprising: from 50% to 94% by weight of an anionic surfactant; from 1% to 30% by weight of an alkyl ethoxy sulfate and from 5% to 35% by weight of water. The paste has a viscosity greater than 10 Pa.s at a temperature of 70.degree. C. and measured at a shear rate of 25 s.sup.-1. The paste has rheological properties making it well-suited to the further processing into high active detergent agglomerate suitable for use in free flowing granular detergent compositions.
