Abstract: A particulate fabric softening composition, comprising one or more ethylenediamine fatty acid diamides and one or more quaternary ammonium salt fabric softeners, the composition having an exothermal transition at a temperature between 60 and 90° C. with an exothermal transition enthalpy of more than 5 J/g measured by DSC with a heating rate of 2° C./min, can be press shaped to multiple use, dryer added fabric softening articles having high initial surface hardness. The fabric softening composition can be made by cooling a molten mixture comprising one or more ethylenediamine fatty acid diamides and one or more quaternary ammonium salt fabric softeners to a temperature of 40° C. or less at a high cooling rate.

Abstract: The present invention relates to a flexible ceramic membranes which, depending on embodiment, are useful as separators for batteries, especially lithium batteries and also as a process for their production. Ceramic or hybridic membranes have the advantage that, whatever the level of flexibility already achieved, they tend to crumble of the ceramic coating on bending. this is prevented by the present membranes, which comprise, on and in a polymeric nonwoven, a solidified ceramic coating which is constructed from two fraction which metal oxide particles of different size and which adheres to the polymeric nonwoven through a network constructed by two different adhesion promoters.
