The invention discloses bar compositions which are milder than soap but have squeaky feel or rinse associated with soap. This is accomplished by ensuring at least a certain portion (at least 1%), or all, of the soluble surfactant system is ion-sensitive. Further, soluble soap comprises less than 1% by wt. of bar, which helps produce a less alkaline pH bar while allowing squeaky feel to be produced.

The invention relates to chiral 3,4-dihydro-2H-pyran compounds and diastereomers thereof, and to the use of these compounds as chiral dopants for liquid-crystalline systems. The invention furthermore relates to non-polymerizable or polymerizable liquid-crystalline compositions which comprise at least one chiral 3,4-dihydro-2H-pyran compound according to the invention, to the use of these non-polymerizable or polymerizable liquid-crystalline compositions for the production of optical components, to the use of the polymerizable liquid-crystalline compositions for printing or coating substrates, for the preparation or production of dispersions and emulsions, films or pigments and optical components of this type, printed or coated substrates, dispersions and emulsions, films and pigments.
摘要:
A process for printing or coating a substrate with a liquid-crystalline composition and at least one non-liquid-crystalline print or coating as a multilayer and a substrate produced by this process is described. The liquid-crystalline composition contains at least one compound having two polymerizable groups and at least one compound having only one polymerizable group, and optional further additives. The non-liquid-crystalline print or coating contains one or more IR- or UV-absorbent or fluorescent dye or pigment. The process and the printed substrate are useful in producing counterfeiting-proof marking of articles.
摘要:
The invention relates to a piston arrangement for a dual-stage piston compressor, comprising a cranksbaft and several cylinders which house the operating piston. Said arrangement allows two or more low-pressure stages and at least one high-pressure stage to be formed. The invention is characterized in that the two or more low-pressure cylinders are arranged in relation to the high-pressure stage in such a way that said two or more low-pressure cylinders are in phase or are offset by less than ±15° and compress in a position which is offset by 180°±20, in relation to one or more high-pressure cylinders.
摘要:
The present invention relates to the use of polymerizable liquid-crystalline compounds for the production of optical elements having color- and polarization-selective reflection, and to optical elements comprising these compounds in monomeric or polymerized form.

摘要:
An interactive graphical application program combines a graphical command language and a control program to enable a user to graphically select and generate an automation sequence to control an automation application. A computer system stores a first program containing flow sequences and a set of controls representing possible hardware for use in the automation application. Structure is graphically displayed depicting each sequence step and transition to the next step in accordance with user selections. The first program is automatically linked with the controls to enable an application software program to be generated in response to user commands.
摘要:
An electroluminescent arrangement contains one or more organic layers, at least one of which is obtained by thermal or radiation-induced crosslinking and contains at least one charge-transporting compound which can carry crosslinkable groups per layer, one of the layers being completely or partially composed of a crosslinkable fluorescent compound which emits fluorescent light in the wavelength range from 400 to 800 nm.
