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. The hard surface cleaning compositions are enzymatic and near neutral in pH. 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. In a preferred embodiment, the hard surface cleaning compositions comprise a biocide.

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.
