Abstract: Specific siloxanes, compositions containing these specific siloxanes, and processes for preparation thereof, are useful for treatment of fabrics, in cleaning and care formulations for the household and for industrial purposes, and in cosmetic, pharmaceutical and dermatological compositions, especially in cosmetic cleansing and care formulations, hair treatment products and hair aftertreatment products, and for cleaning and care of hard surfaces, preferably for cleaning and care of motor vehicles, especially as additive in drying aids for carwash facilities.

Abstract: Crosslinked aminosiloxanes obtainable by reaction of identical or different aminosiloxanes with identical or different epoxide components which are water-soluble hydrocarbons, the hydrocarbons comprising oxygen as well as carbon, and optionally further elements selected from nitrogen, sulphur and phosphorus, the hydrocarbon having on average more than one terminal epoxy group, the epoxy group being a carbooxirane radical, and, further, not more than 50% of all the amino groups having undergone reaction with an epoxide group.

Abstract: An extruder containing a housing having a flow channel for a melt and a perforated plate delimiting the flow channel on the outlet side, where the perforated plate has at least two through-flow areas spaced apart from one another, each through-flow area contains at least one through-flow opening, and the perforated plate is furthermore mounted in a changing device, where the changing device has guide elements, in which the perforated plate can be moved substantially perpendicularly to the flow channel, and the extruder, directly ahead of the perforated plate when viewed in the direction of flow of the melt, has an inlet flow cone, which is structurally separate from the perforated plate, thus allowing the through-flow areas of the perforated plate to be moved relative to the inlet flow cone.

Abstract: The invention relates to an extruder comprising a housing having a flow channel (1) for a melt and a perforated plate (2) delimiting the flow channel (1) on the outlet side, wherein an inlet flow element (3) having passage areas (4) and covering surfaces (5) is arranged so as to be movable ahead of the perforated plate (2) in the direction of flow of the melt in such a way that, when the inlet flow element (3) is moved, a first subset of holes in the perforated plate (2) is exposed and a second subset of holes in the perforated plate (2) is closed, wherein the covering surfaces (5) extend radially from the center of the inlet flow element (3) to the rim thereof.
