Abstract: Disclosed herein is a solid surfactant composition including at least one polymer P1) that includes polymerized units of at least one monomer A), selected from the group consisting of ?, ?-ethylenically unsaturated carboxylic acids, salts of ?,?-ethylenically un-saturated carboxylic acids, ?, ?-ethylenically unsaturated carboxylic acid anhydrides and mixtures thereof, and at least one nonionic surfactant of the general formula (I), characterized in that the solid surfactant composition has a glass transition temperature (Tg) of at least 50° C., determined by differential scanning calorimetry according to DIN EN ISO 11357-2, at a heating rate of 20 K/min. Additionally disclosed herein is a method of using the solid surfactant composition in a cleaning formulation.

Abstract: The present invention provides an improved process for isolating 2,4-bis-(2,4-dihydroxyphenyl)-6-(4-methoxyphenyl)-1,3,5-triazine (DIOPAT) from an aqueous alkaline mixture M comprising the DIOPAT, 2,4-dihydroxybenzophenone, and aluminum salts, wherein the process comprises the steps of precipitating the DIOPAT by acidifying the mixture M to a pH<1; heating the acidified mixture M to a temperature in the range of from 80° C. to 95° C.; and separating of the precipitated DIOPAT from the dissolved 2,4-dihydroxybenzophenone and the dissolved aluminum salts with a ceramic membrane by means of diafiltration.

Abstract: Surfactant systems and compositions incorporating the same are disclosed for use as cleaning compositions and rinse aid compositions. The solid surfactant systems are prilled, pastilled, flaked or granular solids and are incorporated into solid formulations at high concentrations for both improved performance and manufacturing benefits. The methods of using the solid compositions containing the surfactant systems for cleaning applications and rinse aid applications are also disclosed.

Abstract: The present disclosure relates to a washing- and cleaning-active polymer film which includes a mixture of at least one polymer P1) including polymerized units of at least one ?,?-ethylenically unsaturated carboxylic acid or a salt thereof. The washing- and cleaning-active polymer film optionally further includes comonomers and a polyoxyalkylene ether PE). The disclosure furthermore relates to a process for producing such a washing- and cleaning-active polymer film and to a covering or coating for a detergent or cleaner portion which includes such a polymer film.

Abstract: Described herein is a process for preparing solid acrylic acid polymers including: (a) preparing an aqueous acrylic acid polymer solution having a solids content of 30% to 70% by weight by free-radical polymerization, (b) neutralizing the aqueous acrylic acid polymer solution at least partly by adding a base, which results in release of a heat of neutralization, and concentrating the aqueous acrylic acid polymer solution by exploiting the heat of neutralization to give a highly concentrated acrylic acid polymer solution having a solids content of 60% to 80% by weight, (c) shaping and drying the highly concentrated acrylic acid polymer solution.
