ES393146A1 - Liquid washing and cleaning agents - Google Patents

Abstract

Procedure for the preparation of liquid washing and cleaning agents, characterized in that with 5 to 25% by weight, preferably 5 to 20% by weight, of a surfactant component, preferably consisting of synthetic anionic surfactants, the alcohol radicals of which contain 8 up to 14 carbon atoms, preferably 12 to 14 carbon atoms, and 0 to 15% by weight, preferably 5 to 15% by weight of alkali metal salts of lower alcoholic benzenesulfonic acids, 5 to 30% by weight of enhancing substances are combined of detergency, consisting of: a) polyaldehyde-carboxylic acids or polyaldehyde-carboxylates, which are predominantly made up of units of the general formulas **(See formula)** as main components and eventually contain, in secondary number, also units of the general formula **(See formula)** in which A represents a hydrogen atom, a valence of a monovalent or polyvalent metal, especially an alkali metal, preferably sodium, or ammonia, R and R1 are the same or different and signify an alcohol group with 1 to 6 carbon atoms, especially a methyl group, or preferably a hydrogen atom, and R1 can further mean a halogen atom, preferably a chlorine atom, the units of which (I), (II) and (III) can be arranged in any order of succession and in which the average frequency of these units corresponds to a molar content of carboxyl or carboxylate groups of at least 50%, to a molar content of carbonyl groups of not more than 50% and optionally to a molar content of hydroxyl groups in terminal position, optionally totally or partially lactonized from 0.2 to 66%, especially from 1 to 20%, preferably from 1 to 10%, and whose degree of polymerization is between 3 and 600, especially between e 3; and 300, preferably between 3 and 100; and/or b) polyoxy-carboxylic acids or polyoxycarboxylates, which consist predominantly of units of the general formulas (I) **(See formula)** as main components, and contain, optionally together with these, in secondary numbers, also units of the general formula (III), as well as optionally additionally units of the general formulas **(See formula)** in which A and R have the indicated meanings again, whose units (I), (III), (IV), (V), (VI) and (VII) can be arranged in any order of succession and in which the average frequency of these units, even in the absence of one or more of these units, corresponds to a ratio of carboxyl or carboxylate groups to hydroxyl groups that is between 0.5 and 16, especially between 1.1 and 16, preferably between 2 and 9, and whose degree of polymerization is between 3 and 600, especially between 3 and 300, preferably between 3 and 100, and 0 to 25% by weight of other detergency builders, especially alkali metal polyphosphates and/or pyrophosphates. of alkali metal, to form a homogeneous solution or a stable suspension or emulsion, in which the total amount of the mentioned components, possibly including other auxiliary substances present, which are dissolved or possibly suspended in the water serving as a solvent, to yes as in the water-soluble solvents that may be present, it amounts to no more than 65% by weight.
