Abstract: Washing and cleaning agents may include microcapsules comprising a core material where the core material may include at least one fragrance and a shell. The shell may consist of at least one first layer and one second layer with different chemical compositions. The shell may have a biodegradability, measured in accordance with OECD 301 F, of at least 40%. Such agents may be used for conditioning textiles or for cleaning textiles and/or hard surfaces.

Abstract: A microcapsule system having an outer microcapsule with an outer capsule shell is disclosed. The outer microcapsule comprises at least one inner microcapsule with an inner capsule shell and a first fragrance composition. The inner microcapsule comprises a second fragrance composition that differs from the first fragrance composition. Methods for the production of such micr, products that contain said microcapsules, methods for producing polysensory olfactory impressions and to the corresponding use of the microcapsule system.

Abstract: An aqueous composition for the post-treatment of washed laundry containing 0.1 to 30% by weight of a water-insoluble quaternary ammonium compound, 0.1 to 50% by weight of a water-soluble quaternary ammonium compound, 0 to 5% by weight of a terpene compound, 0.1 to 20% by weight of a water-soluble acid, and 0.1 to 20% by weight of an emulsifier.

Abstract: Detergent mixtures containing(a) esterquats corresponding to formulae (I), (II) or (III): ##STR1## in which R.sup.1 CO is an acyl radical containing 6 to 22 carbon atoms, R.sup.2 and R.sup.3 independently of one another represent hydrogen or have the same meaning as R.sup.1 CO, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 independently of one another represent an alkyl group containing 1 to 4 carbon atoms or a (CH.sub.2 CH.sub.2 O).sub.q H group, m, n and p together are 0 or numbers of 1 to 12, q is a number of 1 to 12 and X stands for halide, alkyl sulfate or alkyl phosphate,(b) soil-repelling polymers containing ethylene terephthalate or polyethylene glycol terephthalate groups, and(c) from 1% to 50% by weight of alkyl or alkenyl sulfates, based on the weight of the esterquats.
