Abstract: The invention relates to a composition which comprises at least one polyorganosiloxane in aqueous solution or dispersion, in the absence of additional dispersants.

Abstract: The present invention provides polishes for surfaces, comprising aminoorganopolysiloxanes (A) which are solid at room temperature, contain fluoro groups and are able to change their aggregate state reversibly as a result of changes in temperature.

Abstract: The invention relates to organopolysiloxanes that have amino groups and are solid at room temperature which can reversibly change their states of aggregation on the basis of temperature changes. Preparations containing these organopolysiloxanes are useful in the cleaning, care, and hydrophobicization of surfaces.

Abstract: The invention relates to organopolysiloxanes with dye residues comprising units of the general formula R1a(RO)bAcR2dSiO(4−a−b−c−d)/2  (I) wherein R can be identical or different and is hydrogen atom or monovalent, substituted or unsubstituted hydrocarbon radical, R1 can be identical or different and is hydrogen atom or monovalent, SC-bonded hydrocarbon radical, R2 can be identical or different and is substituted, monovalent, Si—C bonded hydrocarbon radical, A can be identical or different and is a radical of a water-soluble organic dye containing at least one of sulfonic acid groups, sulfonate groups, or metal complexes thereof, a is 0, 1, 2, or 3, b is 0, 1, 2 or 3, d is 0, 1, 2, or 3 and c is 0, 1 or 2 with the proviso that the sum of a, b, c and d is less than or equal to 3, the organopolysiloxanes have at least one radical, and, in the units of the formula (I) where c is other than 0, d is 0.
