An antimicrobial cleaning composition having a pH of from about 9 to about 14 wherein the composition comprises a bispyridinium alkane antimicrobial active and the composition is substantially free of a quaternary ammonium antimicrobial active.

The need for a spray application of detersive compositions comprising perfume and low levels of surfactant, which provides more even coverage of the surface to be treated, while limiting nose and throat irritation is met by limiting the spray droplet size, such that the spray droplets have a particle size distribution such that the Dv10 is greater than about 40 microns.

The present invention is directed to rinse aid compositions and methods for making and using the rinse aid compositions. The compositions of the invention include a sheeting agent, a defoaming agent, and an association disruption agent. The rinse aid compositions of the present invention result in a faster draining/drying time on most substrates compared to conventional rinse aids. The rinse aid compositions of the present invention are especially suitable for use on plastic substrates.

Process for making solid methylglycine diacetate (MGDA) alkali metal salt (A), said process comprising the steps of (a) providing a 40 to 60% by weight aqueous solution of said salt (A) having a temperature in the range of from 50 to 90° C., (b) crystallizing salt (A), (c) removing said crystalline salt (A) from the mother liquor by filtration, and (d) subjecting the water containing filter cake from step (c) to an extrusion step.

A method of making a translucent cleaning composition is disclosed. The method includes providing a perfume; providing a hydrogen bond receiving compound; providing a hydrogen bond providing compound; combining the hydrogen bond receiving compound with the hydrogen bond providing compound to create a eutectic liquid; adding the perfume to the eutectic liquid to create a perfumed eutectic liquid; and adjusting the pH of the perfumed eutectic liquid to above 6.0.

The present invention relates to a composition for treating a semiconductor substrate, and particularly to a composition for treating an edge portion of a wafer coated with polysilazane.

According to the composition for treating a semiconductor substrate according to the present invention, it is possible to uniformly maintain the quality of the composition in terms of management and to uniformly treat the boundary of the wafer in terms of processing. In addition, by improving the straightness of the boundary portion where polysilazane is removed, it is possible to significantly reduce the defect rate of the product and to stably improve the productivity yield.

A process liquid composition for moving a lifting defect level of a photoresist pattern having hydrophobicity represented by a contact angle of 75° or larger of a photoresist surface with respect to water in a photoresist patterning process, and a preparation method thereof are proposed. The process liquid composition includes 0.00001% to 0.1% by weight of a fluorine-based surfactant, 0.00001% to 1.0% by weight of a triol derivative, a tetraol derivative, or a mixture thereof, and the remaining proportion of water. The process liquid composition has a surface tension of 45 mN/m or less and a contact angle of 65° or smaller.

Surfactants based on a newly discovered class of compounds include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety, and a serine-leucinol dipeptide linked to the lipid oligomer. Such surfactants can be used to create an oil-in-water or water-in-oil emulsion by mixing together a polar component; a non-polar component; and the surfactant. Biosurfactants of the newly discovered class can be made by isolating and culturing a microorganism which produces the biosurfactant, and then isolating the biosurfactant from the culture. A microorganism can be engineered to produce biosurfactant of this newly discovered class by expressing a set of heterologous genes involved in the biosynthesis of the biosurfactant in the microorganism.

A tile system for covering a surface. The tile system comprises a first tile assembly connected to a second tile assembly by a connector. Each tile assembly comprises a first tile stacked on a second tile, the first tile and the second tile joined to a reinforcing material disposed therebetween. The connector comprises a first component and a second component that is complementary to the first component. The first component is mounted to the first tile assembly, and the second component is mounted to the second tile assembly.

The present disclosure relates to compositions and methods of using the compositions for treating a floor surface. The disclosed compositions clean the floor surface, repair damage, or maintain the original look of the floor. The disclosed compositions also do not provide a permanent finish on the floor, are temporary coatings, or do not significantly change the gloss of the floor after application.
