The present invention relates to new alkaline, preferably highly alkaline, cleaning solutions comprising surfactants with improved stability and cleaning performance under such conditions. It further relates to novel surfactants.

The present invention provides a method for washing a hard article, the method including: the contact step of bringing a detergent liquid obtained by mixing (a) a potassium internal olefin sulfonate and (b) water having a hardness of 5° DH or more, into contact with the hard article, and the step of rinsing the hard article after the contact step with water having a hardness of 5° DH or more, wherein the detergent liquid at 30° C. or more is brought into contact with the hard article in at least a part of the contact step.

A structured liquid detergent composition includes water, an anionic detergent surfactant, and a nonionic detergent surfactant. A ratio of the anionic detergent surfactant to the nonionic detergent surfactant is from about 0.5 to about 20. The structured liquid detergent composition further includes a zwitterionic or amphoteric surfactant and a bacterial-derived cellulose network. The structured liquid detergent composition exhibits improved rheological properties.

Solid laundry softening compositions and applications of use are disclosed. Solid laundry softening compositions combine quaternary ammonium compounds with an inorganic carrier to provide a flowable powder for solidification in a pressed or extruded solid composition. A high loading of quaternary ammonium compound in the inorganic carrier, including an inorganic salt, can be further combined with softening boosters, processing aids, surfactants, and/or additional functional ingredients to provide stable solid compositions.

The present invention relates to an aqueous composition for removing soils from a surface to be cleaned, formed from water, a detergent mixture and a rinse aid, wherein the detergent mixture comprises a peroxidation catalyst and wherein the rinse aid comprises an oxygen source. Such a composition may provide a more effective cleaning behaviour. The present invention further relates to a method for removing soil from a surface to be cleaned comprising applying to the surface to be cleaned a composition according to the invention.

A transport medium is disclosed that can be utilized for both sample collection and molecular diagnostic applications. The transport medium can be utilized with multiple types of biological samples and maintains the stability of nucleic acid present in the biological samples so that one or more nucleic acid assay target(s) present in the biological sample is not substantially degraded during storage and shipping. Also disclosed are kits containing the transport medium, mixtures that include a biological sample disposed in the transport medium, and methods of producing and using the medium.

An object of the present invention is to provide a cleaning liquid for a semiconductor substrate, which has excellent corrosion prevention performance for a metal-containing layer. In addition, another object of the present invention is to provide a method for cleaning a semiconductor substrate.

The cleaning liquid of an embodiment of the present invention is a cleaning liquid for a semiconductor substrate that has been subjected to a chemical mechanical polishing treatment, in which the cleaning liquid includes a component A having two or more onium structures in a molecule, and water, and has a pH of 7.0 to 11.8 at 25° C.

Effervescent compositions for preparing home care products and methods for preparing the same are disclosed. The effervescent compositions may include an effervescent base, one or more surfactants, one or more solidifying agents, and one or more disintegrant agents. The effervescent base may include one or more alkali metal carbonates and one or more acids. The one or more alkali metal carbonates and the one or more acids may be present in a weight ratio of from about 1:1 to about 5:1. The effervescent composition may be substantially free of water. The effervescent composition may have a dissolution time of from about 6 min to about 12 min. The method for preparing the effervescent composition may include contacting the effervescent base, the surfactants, the solidifying agents, and the disintegrant agents with one another to prepare a mixture, which may be a homogenous mixture.
