  • Instant Vesicular Product
    Publication number: 20120039948
    Abstract: A powder of reversed vesicles, which comprises one or more non-ionic surfactants and optionally a lipophilic stabilising factor and a bio-active agent, is provided. The product is prepared by making a dispersion of reversed vesicles in a suitable apolar vehicle, which vehicle is subsequently removed. In admixture with one or more excipients the product can be incorporated in compositions.

  • Topical preparation containing a suspension of solid lipid particles
    Patent number: 5904932
    Abstract: An aqueous suspension of solid lipoid nanoparticles, comprising at least one lipid and preferably also at least one emulsifier, for topical application to the body, is provided. The solid lipoid nanoparticles have a mean particle size of between 50-1000 nm and their concentration is between 0.01-60 wt %, by weight of the suspension. Also topical preparations, comprising said suspension of solid lipoid nanoparticles, are provided. A medicament can be incorporated into the continuous phase of the suspension or in a vehicle, which is added to said suspension.
