  • Patent number: 5747012
    Abstract: A process for preparing a composition suitable for topical application to human skin is disclosed. The process comprises mixing particles of metallic oxide dispersed in oil and having a primary particle size less than 0.2 micrometer with one or more emulsifiers, an aqueous phase and a hydrophilic organic sunscreen so as to prepare an emulsion. The composition contains up to 10 percent by weight metallic oxide and up to 7 percent by weight hydrophilic organic sunscreen. The emulsions are useful as sunscreen compositions, skin protectants, moisturisers, and after-sun lotions. The measured Sun Protection Factor for a composition of the invention is considerably higher than would be expected from a knowledge of the individual UV absorbing characteristics of the metallic oxide and the hydrophilic organic sunscreen.

  • Patent number: 5723617
    Abstract: A series of novel pyrrolo?2,1-a!isoquinoline dyes has been prepared using readily available starting materials via a simple synthetic pathway. These dyes have narrow absorption bands in the range of 500-900 nm. Those that absorb in the near-infrared region (700-1400 nm) lack significant absorption in the 300-400 nm ultraviolet region of the spectrum; this is an advantage for use in an applications such as imaging setting film. In addition, the greater thermal and chemical stability of these dyes in comparison to their indolizine analogues should be valuable in many applications.
