  • Publication number: 20130263388
    Abstract: An epilatory composition, substantially provided as flat strips, comprises a gel-like matrix material, for example a rosin-based or sugar-based material and, mixed with the matrix material, a particulate material, for example colloidal particles of fumed silica. The particles reduce the tendency of the epilatory composition to flow, under warm ambient conditions.

  • Patent number: 8444708
    Abstract: An epilatory composition of the adhesive type comprises a gel-like matrix material, for example of a rosin-based or sugar-based material, together with 0.1-5 wt % of a branched polyalkene, for example polyisobutene. The resulting compositions offer skin care benefits while maintaining excellent viscoelastic and adhesive properties.

  • Publication number: 20080213978
    Abstract: The present invention discloses methods and apparatuses for substrate singulation. Embodiments of the present invention comprise cryogenic-assist scribing or cutting mechanism for debris reduction, preferably cryogenic-assist laser scribe or cutting; controlling mechanism for debris flow and redeposition during laser process; and integrated, dry debris removal scribing process with breaking mechanism. An exemplary embodiment comprises an integrated housing for aligning a laser beam with the cryogenic cleaning beam. The integrated housing is preferably made of low thermal conductivity material to provide a high temperature gradient between the low temperature of the cryogenic fluid and the ambient temperature, preventing condensation of the moisture. The entire areas, or the critical areas of the apparatus can also be purged with flowing “dry” inert gases to further reduce the condensation moisture. Reactive gas can be introduced to react with debris, converting into gaseous form for ease of removal.

  • Publication number: 20060002878
    Abstract: The present invention provides a depilatory patch comprising a layer of depilatory composition carried by a substrate. The depilatory patch is arranged, in use, to be applied to the skin of a user and left for a prescribed time period before being removed. The depilatory composition acts to degrade or destroy hair on the skin where the patch has been applied. The invention also extends to methods of manufacturing depilatory patches of the invention, and to depilatory methods using such patches.
