Abstract: An air guidance device for a vertical take-off and landing aircraft is provided. A nacelle device with a drive device is connected via a pylon device to a wing of the vertical take-off and landing aircraft and is pivotable by a pivoting device, about an axis of rotation between a first position, such as a propulsion position, and a second position, such as a lift position, relative to the pylon device. A first inlet opening of the air guidance device is arranged on the pylon device in a region in which air conveyed by the drive device in the second position impinges on the pylon device and/or in a region of maximum propeller-generated pressure.

Abstract: The stability of antiperspirant or deodorant compositions comprising an aqueous solution of an antiperspirant or deodorant salt that has been thickened by a polyquaternium derivative of an hydroxycellulose and containing lypophylic organic material can be improved by employing a stabilising amount of propylene glycol, preferably selected in the range of from 1.5 to 5% by weight, thereby enabling the formulation to maintain its viscosity better or longer or under less favourable climatic conditions.

Abstract: An aqueous antiperspirant or deodorant oil in water emulsion suitable for being dispensed through a roll-on exhibiting superior consumer attributes and comprising a continuous aqueous phase containing an antiperspirant or deodorant active, an ethoxylated ether emulsifier or mixture having an average HLB of from 7 to 9 and a dispersed oil phase comprising a plant oil such as a fatty acid triglyceride and a particulate silica and especially a hydrophobic fumed silica.
