The invention relates to a solid toilet block having at least a first composition and a second composition obtained by a non-concentric coextrusion step, and to a method for producing such a toilet block and to a device having such a toilet block.

Provided herein are methods for making 3D printed parts by additive manufacturing using post processing cleaners.

The need for a liquid hand dishwashing composition which provides for uniform dosing, even when the bottle is shaken or when the user dispenses using multiple successive squeezes, is met by formulating the liquid hand dishwashing composition with an anionic surfactant, a co-surfactant, and microfibrous cellulose derived from wood.

Described is a post chemical-mechanical-polishing (post-CMP) cleaning composition comprising or consisting of: (A) one or more water-soluble nonionic copolymers of the general formula (I) and mixtures thereof, formula (I) wherein R.sub.1 and R.sub.3 are independently from each other hydrogen, methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-Butyl, or sec-butyl, R.sub.2 is methyl and x and y are an integer, 1 (B)poly(acrylic acid) (PAA) or acrylic acid-maleic acid copolymer with a mass average molar mass (Mw) of up to 10,000 g/mol, and (C) water, wherein the pH of the composition is in the range of from 7.0 to 10.5. ##STR00001##

A method, system and cleaning solutions for the ultrasonic cleaning of drill cuttings and the resulting cleaned drill solids is described. The drill cuttings are characterized by their liquid/solid composition, texture of solids and size of particulates. A cleaning solution formula having surfactant(s) and viscosity agent(s) is selected based on the characterization of drill cuttings. Drill cuttings are contacted with the selected cleaning solution and subjected to ultrasonic vibrations simultaneously for a period of treatment and vibration time. Contaminants from drill cuttings are removed to beneficial use standards and the resulting cleaned drill solids may be reused at the well site. The cleaning may occur at a well site in conjunction with drilling activity and the cleaning solution may be changed to adapt to changes in the drill mud and/or cuttings characteristics.

Described herein is a formulation including (A) at least one nonionic surfactant, (B) at least one graft copolymer formed from (a) at least one graft base selected from nonionic monosaccharides, disaccharides, oligosaccharides and polysaccharides, and side chains; and (C) a total of zero to 0.5% by weight of methylglycinediacetic acid (MGDA) and glutaminediacetic acid (GLDA) and alkali metal salts of MGDA and GLDA and a total of zero to 0.5% by weight of citric acid or an alkali metal salt of citric acid, where figures in % by weight are based in each case on a solids content of the formulation in question.

A neutral or acidic automatic dishwashing detergent composition including a pH regulator system and a cleaning agent selected from the group consisting of cleaning surfactants, soil suspending polymers and mixtures thereof wherein the weight ratio of the pH regulator system to the cleaning agent is from 3:1 to 1:1 system and wherein the detergent composition includes from 0.01% to 5% by weight of the composition of a perfume.

The invention provides methods for preparing and purifying compounds which can be used as environmentally compatible detergents, and compounds obtainable by such methods.

A process for producing a formulation that is solid at up to a temperature of at least 60 C., wherein (a) at least one nonionic surfactant of the general formula (I), R.sup.1CH(OH)CH.sub.2-(AO).sub.xR.sup.2 (I) (wherein: R.sup.1 is C.sub.4-C.sub.20-alkyl, R.sup.2 is C.sub.8-C.sub.20-alkyl, AO are each independently C.sub.2-C.sub.4-alkylene, and x is in a range from 5 to 100), is mixed in a molten state with (b) at least one second substance selected from polyethylene glycol and nonionic surfactants different from surfactants of general formula (I), confectioned, mixed and ground in the solid state with (c) silica or silicate and (d) at least one auxiliary selected from alkali metal citrate, alkali metal carbonate or at least one chelating agent selected from compounds of the general formula (II), R.sup.3CH(COOM.sup.1)-N(CH.sub.2COOM.sup.1).sub.2 (II) (wherein: R.sup.3 is C.sub.1-C.sub.4-alkyl, phenyl, benzyl, CH.sub.2OH and CH.sub.2CH.sub.2COOM.sup.1, and M.sup.1 is an alkali metal or a combination of at least two alkali metals). Furthermore granules and their use.

Surfactants capable of releasing and/or dissolving polymers to form water-soluble or water-dispersible polymer solutions are disclosed. In addition, polymer compositions containing a water-in-oil emulsion comprising the surfactant are provided and can be used, for example, in methods of dissolving a polymer. Also disclosed are detergent compositions and methods of cleaning articles and/or membranes using the surfactants herein. These surfactants and polymer compositions can be used in various industries including for water clarification, papermaking, sewage and industrial water treatment, drilling mud stabilizers, and enhanced oil recovery.
