The present invention relates to a composition of spherical microparticles composed of a wall material and at least one cavity that comprises a gas and/or a liquid, which have pores on the surface thereof, wherein the spherical microparticles have a mean particle diameter of 10-600 m and wherein at least 80% of those microparticles, the particle diameter of which does not deviate from the mean particle diameter of the microparticles of the composition by more than 20%, each have on average at least 10 pores, the diameter of which is in the range from 1/5000 to 1/5 of the mean particle diameter, and, furthermore, the diameter of each of these pores is at least 20 nm, wherein the wall material consists of a composition comprising at least one aliphatic-aromatic polyester and at least one additional polymer, wherein the additional polymer is selected from the group consisting of polyhydroxy fatty acids, poly(p-dioxanones), polyanhydrides, polyesteramides, polysaccharides and proteins, to a method for the preparation thereof and use thereof.

Described herein is a process for producing perfume- or flavor-containing microcapsules with improved deposition of encapsulated actives on targeted surfaces such as fiber, hair and skin, which can be used in home or personal care products. Also described herein are microcapsules obtainable by such a process and consumer products including these microcapsules.

Catechol-group-containing polymers with amine or amide functionality, containing at least one repeating unit of the formula (I) and at least one repeating unit of the formula (II) and optionally further repeating units

##STR00001##

The repeating units of the formula (II) are different from the repeating units of the formula (I) and the molar ratio of the units of the formula (I) to the units of the formula (II) is in the range from 0.5-to-1 to 4-to-1, are suitable for the dirt-repellent finishing of substrate surfaces, particularly surfaces of textiles, glass, ceramics or plastics. The polymers have an excellent adhesion to these surfaces, so that during cleaning of a substrate surface they adsorb to the substrate surface from the aqueous cleaning or washing liquor and realize their effect.

The present invention discloses a cleaning liquid for a ship ballast water treatment filter, an online cleaning device and an online cleaning method. The online cleaning device comprises a filter cleaning pipeline and a cleaning liquid preparation tank located in the filter cleaning pipeline. The cleaning liquid preparation tank is provided with a cleaning liquid outlet and a cleaning liquid reinjection opening. The filter cleaning pipeline comprises a cleaning liquid injection pipeline located between the cleaning liquid outlet of the cleaning liquid preparation tank and a filter water inlet, and a cleaning liquid reinjection pipeline located between a filter water outlet and a cleaning liquid reinjection opening of the cleaning liquid preparation tank. The cleaning liquid prepared in the cleaning liquid preparation tank is injected into the filter through the cleaning liquid injection pipeline and is re-injected into the cleaning liquid preparation tank through the cleaning liquid reinjection pipeline.

This invention relates to cleaning particles, methods for their preparation, cleaning compositions and their use for laundry cleaning of soiled substrates.
