The present invention relates to a hand dishwashing cleaning composition including a desirable foam rheology profile. In particular, the composition includes a surfactant system comprising an alkyl polyglucoside surfactant having a mixture of: (a) 60% or more of a first alkyl polyglucoside surfactant material having an average carbon chain length between 10 and 12; and (b) 40% or less of a second alkyl polyglucoside surfactant material having an average alkyl carbon chain length between 12 and 16. Such compositions exhibit surprising and unexpected good sudsing profile, preferably suitable suds rheology and aesthetics, especially when applied onto a cleaning implement upon dilution with wash water during the dishwashing process.

Disclosed herein are cleaning compositions including water, at least one cationic surfactant, and at least one nonionic surfactant.

Certain fatty acid amide-based surfactants such as cocamide DEA (also known as coco(nut) diethanolamide or coco(nut) DEA) when dissolved or dispersed in a cutting oil (diesel, light cycle oil, naphtha, and such other petroleum distillates) produce a petroleum distillate having significantly enhanced solvency for heavy residuals. Such solutions or dispersions are especially useful for cleaning vessels and similar equipment in refineries by circulating the solution or dispersion in the vessel, optionally with the application of heat.

Laundry detergents and their use for cold-water cleaning are disclosed. The detergents comprise a lipase and a mid-chain headgroup surfactant or an alkylene-bridged surfactant. The mid-chain headgroup surfactants have a C.sub.14-C.sub.30 alkyl chain and a polar group bonded to a central zone carbon of the C.sub.14-C.sub.30 alkyl chain. The alkylene-bridged surfactants comprise a C.sub.12-C.sub.18 alkyl chain, a polar group, and a C.sub.1-C.sub.2 alkylene group bonded to the polar group and a central zone carbon of the C.sub.12-C.sub.18 alkyl chain. Surprisingly, when combined with lipases, detergents formulated with the mid-chain headgroup or alkylene-bridged surfactants effectively liquefy greasy soils at low temperature and provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

The disclosure relates to hard surface cleaning compositions, methods of making the hard surface cleaning compositions, and methods of using the hard surface cleaning compositions. In particular, the hard surface cleaning compositions have reduced surface tension for cleaning surfaces with low surface free energy. Preferably, the hard surface cleaning compositions have low contact angles on a variety of surfaces.

The present disclosure provides derivatives of amino acids that have branched alkyl structures and surface-active properties. The amino acid can be naturally-occurring or synthetic, or they may be obtained via a ring-opening reaction of a lactam, such as caprolactam. The amino acid may be functionalized to form a compound that is surface-active and have advantageous surfactant characteristics. The compounds of the present disclosure have low critical micelle concentrations (CMC) as well as superior ability to lower the surface tension of a liquid.

Detergents useful for cold-water cleaning and mid-chain headgroup and alkylene-bridged surfactants useful therein are disclosed. The mid-chain headgroup surfactant has a C.sub.14-C.sub.30 alkyl chain and a polar group bonded to a central zone carbon of the alkyl chain. The alkylene-bridged surfactant has a C.sub.12-C.sub.18 alkyl chain, a polar group, and a C.sub.1-C.sub.2 alkylene group bonded to the polar group and a central zone carbon of the C.sub.12-C.sub.18 alkyl chain. Preferred surfactants in these classes are alcohol sulfates, alcohol ethoxylates, ether sulfates, sulfonates, arylsulfonates, alcohol phosphates, amine oxides, quaterniums, betaines, and sulfobetaines. Surprisingly, detergents formulated with the surfactants provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.
