Abstract: Aqueous compositions comprise maleic acid and a surfactant consisting of a cationic surfactant, a zwitterionic surfactant, an amphoteric surfactant or mixtures thereof. Said compositions are substantially odor-free and do not contain any perfume.

Abstract: Aqueous liquid detergent compositions are described which comprise a proteolytic enzyme wherein the proteolytic activity is reversibly inhibited by a peptide trifluoromethyl ketone.

Abstract: Aqueous liquid detergent compositions are described which comprise a proteolytic enzyme wherein the proteolytic activity is reversibly inhibited by a peptide aldehyde.

Abstract: A) A metallocatalyst selected from: a) metalloporphin and water-soluble or water-dispersable derivatives thereof; b) metaloporphyrin and water-soluble or water-dispersable derivatives thereof; c) metallophthalocyanine and water-soluble or water-dispersable derivatives thereof; B) a polyamine N-oxide containing polymers; C) an efficient amount of a bleaching agent.

Abstract: The present invention concerns cellulase-containing granular detergent compositions which are in a "compact" form, i.e. they are of a relatively high density and contain a relatively low amount of inorganic filler salt compared to conventional detergent compositions. In the detergent compositions herein the cellulase is defined by the C14CMC method described herein and preferably comprises a specific single-component endoglucanase.

Abstract: Yeast or other micro-organism cells for use in the encapsulation of liquids (e.g. liquid bleach activators for use in laundry detergent compositions) are deodorised by treatment with a peroxygen bleach, e.g. hydrogen peroxide.

Abstract: Solid Peroxyacid bleach precursor compositions are provided in which the external surfaces of a particulate peroxyacid precursor material is treated with from 2% to 20% by weight of a solid organic acid compound of Mpt>30.degree. C. and an aqueous solubility of at least 20 g/100 g water at 20.degree. C. The bleach precursor material, when so treated, perhydrolyses after 3 minutes in a standard test at 20.degree. C., to at least 90% of the extent of the untreated bleach precursor material under the same conditions. Preferred organic acid compounds are monomeric aliphatic hydroxycarboxylic and polycarboxylic acids such as citric, lactic and glycolic acids. Detergent compositions containing the treated peroxyacid bleach precursor particulates are also disclosed.
