Abstract (en)

The invention relates to capsules containing detergents for releasing the same during a cleaning process. Said capsules contain at least one surfactant of the formula [R1-O-(CH2-CH2-O-)n-L] <-> [R2-NR4H-R3] <+> selected from mono, di or trialkanolammonium salts of alkyl ether sulphates, with a molecular weight of at least 200 g/mol, preferably at least 300 g/mol. In said formula, R1 represents a hydrocarbon radical, comprising at least 6 carbon atoms; n represents a whole number between 1 and 8; L represents -SO3; R2 is a linear or branched alcohol group, comprising between 1 and 10 carbons and at least one hydroxyl group; R3 and R4 are identical or different and are selected from the group consisting of hydrogen, linear and/or branched alcohol groups, containing between 1 and 10 carbon atoms and at least one hydroxy group and linear and/or branched alkyl groups with between 1 and 10 carbon atoms. The surfactant can be present either in the capsule jacket or the capsule fill material, or both. The inventive capsule has a high proportion of detergent substances. The capsule jacket material is preferably a macro-molecular native natural substance and/or is chemically and/or physically modified, preferably gelatine.
