A viscoelastic, solid surfactant composition, containing, (i) a total amount of 0.1 to 70 wt % of at least one surfactant, (ii) a total amount of more than 1 wt % of at least one benzylidene alditol compound of formula (I), and (iii) water, is a readily soluble, aesthetically pleasing and storage-stable form of a solid composition for providing surfactant-containing liquors.

The invention relates to a surfactant composition comprising a primary surfactant of sulfonated methyl ester (SME) of a fatty acid having a chain length of 16 to 18 carbon atoms (C16-C18); a secondary surfactant having a carbon chain length shorter than that of the primary surfactant; a non-ionic co-surfactant; a hydrotrope; and a solvent. The secondary surfactant can be a SME of a fatty acid having a chain length of 12 to 14 carbon atoms (C12-C14) or sodium lauryl ether sulfate (SLES). The invention also relates to use of said surfactant composition as a surfactant system in a detergent.

The purpose of the present invention is to provide means for sufficiently removing residues on a surface of an object which has been polished including silicon nitride, silicon oxide, or polysilicon. Provided is a composition for surface treatment including an anionic surfactant having a molecular weight of 1,000 or less and water, the composition having a pH of less than 7, wherein a ratio of a molecular weight of a hydrophilic moiety to a molecular weight of a hydrophobic moiety (the molecular weight of the hydrophilic moiety/the molecular weight of the hydrophobic moiety) of the anionic surfactant is 0.4 or more (in which the hydrophobic moiety is a hydrocarbon group having 4 or more carbon atoms and the hydrophilic moiety is a part excluding the hydrophobic moiety and a counterion), and the composition for surface treatment is used for surface treatment of an object which has been polished including at least one selected from the group consisting of silicon nitride, silicon oxide, and polysilicon.

A modified aqueous acid composition comprising: nitric acid; sulfuric acid; a compound comprising an amine moiety and a sulfonic acid moiety; and a peroxide. Also disclosed are methods of using such composition.

An anti-microbial laundry detergent composition comprising an anti-microbial agent that is a diphenyl ether, an organic acid and an anionic surfactant comprising a C.sub.6-C.sub.20 linear alkylbenzene sulfonate, wherein the composition has a neat pH of from 1.5 to 5.0.

The invention comprises a process for preparing mixtures of DEFI and amide taurate (ATA) having excellent yields of ATA and substantial absence of browning of final ATA and DEFI mixtures. The process permits much greater flexibility in ratios of DEFI to ATA. The invention further relates to mixtures prepared by processes of the invention.
