A concentrate composition comprising: (a) at least 10 wt % of a glycol ester of a fatty acid; (b) at least one acyl alkyl isethionate surfactant of formula (I):

##STR00001## wherein R.sup.1 represents an optionally substituted C.sub.4-C.sub.36 hydrocarbyl group; each of R.sup.2, R.sup.3, R.sup.4 and R.sup.5 independently represents hydrogen or a C.sub.1-C.sub.4 alkyl group and wherein at least one of R.sup.2, R.sup.3, R.sup.4 and R.sup.5 is not hydrogen; and M.sup.+ represents a cation; and (c) at least one zwitterionic or amphoteric surfactant.

Alkaline detergent compositions and methods of using the same for washing of shell eggs are provided that exhibit rapid drying characteristics. The detergent compositions comprise an alkyl polyglucoside surfactant, an alkaline agent, sodium silicate, and water.

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.

A cleaning composition for an oral appliance, including the following components (A) and (B): (A) an unsaturated fatty acid having 10 or more and 20 or less carbon atoms or a salt thereof in an amount of 0.5 mass % or more and 14 mass % or less in terms of the fatty acid, and (B) one or more surfactants selected from the group consisting of an anionic surfactant (b1), a nonionic surfactant (b2), and an amphoteric surfactant (b3), and the composition has a pH at 25° C. of 5.5 or higher and 14 or lower.

Disclosed herein are cleaning compositions, e.g., dishwashing compositions, comprising one or more anionic surfactants comprising sodium laureth sulfate (SLES), one or more amphoteric surfactants, and an additive selected from caprylyl glycol, ethanol, and a combination thereof, wherein the composition contains less than 1 ppm. The cleaning compositions may further comprise a linear alkylbenzene sulfonate (LAS). Methods of making and cleaning a hard surface using such compositions are also provided.

The invention discloses synergistic combinations of surfactant blends and cleaning compositions employing the same. In certain embodiments a surfactant system is disclosed which includes an extended anionic surfactant with novel co-surfactants including one or more of an alkyl glycerol ether, an ethoxylated alkyl glycerol ether, an alcohol ethoxylate and/or a gemini surfactant. This system forms emulsions with, and can remove greasy and oily stains, even those comprised of non-trans fats. The compositions may be used alone, as a pre-spotter or other pre-treatment or as a part of a soft surface or hard surface cleaning composition.

A composition comprises from 0.1 to 30 wt-% of one or more amino acids, 0.1 to 30 wt-% of one or more surfactants, and optionally one or more hydrotropes. The amino acids may be selected from arginine (“ARG”), lysine (“LYS”), histidine (“HIS”), glycine (“GLY”), or combinations thereof. The composition can be formulated as a cleaning composition, such as a hard surface cleaner, a floor cleaner, or a degreaser. The composition can be used in a method for treating a surface, where the composition is applied to the surface and allowed to remain on the surface for a length of time, and the surface is then wiped.
