  • Patent number: 5511322
    Abstract: In a process for treating an object by a hot-air flow directed on the object by a hand-held air blower which is provided with a heating device and a fan, the heating device is controlled proportionally as a function of distance. The hand-held air blower has a distance detecting device for carrying out the process. The distance detecting device has an output for determined measured distance values. Proportional control signals for controlling the output control device are formed by a comparison device from the measured distance values and from a given temperature value of a temperature selector.

  • Patent number: 5503826
    Abstract: The new keratin-reducing substances useful in compositions for permanent shaping of hair are glyceryl esters of cysteine, especially the monoglyceryl esters. As monoglyceryl esters of cysteine 2-amino-3-mercaptopropionic acid-(2',3'-dihydroxypropyl)ester and 2-amino-3-mercaptopropionic acid-(1',3'-dihydroxyisopropyl)ester are particularly preferred. A preferred embodiment of the compositions for permanent shaping of hair consists of a ready-to-use mixture of a water-free component including at least one glyceryl ester of cysteine and at least one other component which is kept physically separately from the water-free component until the mixture is prepared. The compositions also can include other conventional ingredients normally used in permanent shaping compositions such as surfactants and thickeners. The compositions have a preferred pH range of 6.0 to 8.5 and contain from 8 to 28 percent by weight of the glyceryl esters of cysteine.

  • Patent number: 5424062
    Abstract: The process for permanent shaping of hair including the steps of treating the hair with a hair shaping agent, bringing the hair into a desired shape before and/or after treating the hair with the shaping agent, rinsing with water as needed, subjecting the hair to an oxidative aftertreatment, setting the hair to form a permanent wave and drying. To provide a permanent shaping which does not leave the hair with an unpleasant odor and is safe for the hair, the hair shaping agent consists essentially of an aqueous composition containing from 0.1 to 30% by weight of at least one Bunte-salt and from 0.5 to 30% by weight of at least one sulfite or hydrogen sulfite. The sulfites and hydrogen sulfites are selected from the group consisting of alkali metal and ammonium sulfites and hydrogen sulfites and alkanolamine salts of sulfurous acid.
