  • Publication number: 20160361252
    Abstract: An anhydrous multiphase gel system consisting of an outer lipid matrix and an inner phase gelled by means of a polymer is described, which can be obtained by a) Melting the lipid phase with the formation of a liquid lipid phase, b) Mixing and homogenizing polymers or polymer blends capable of swelling with the formation of a polymer phase to be dispersed, c) Combining the polymer phase with the liquid lipid phase and homogenizing the phases, and d) Cold stirring the phase mixture until a solid gel-like mixed structure of the entire system is formed. The anhydrous multiphase gel system is particularly suitable for taking up difficultly soluble active substances in high concentration and for providing topical and transdermal applications. The described system is called an EDRS, “Entrapped Drug Reservoir System”.

  • Patent number: 7604812
    Abstract: The invention provides novel hypoallergenic and non-irritant medical skin care formulations being water-in-oil emulsions. The formulations are free from ingredients with a known allergenic potential, such as fragrances, preservatives, colorings, plant extracts, PEGs, cetylstearyl alcohol, lanolin alcohol, lower alcohols and proteins, thus being particularly suitable for patients with sensitive dry skin. The skin care formulations of the invention are useful in the prophylaxis and treatment of dry, sensitive skin or in the therapy or therapy support of eczematous or psoriatic skin and exhibit favorable sensorial properties. The invention furthermore provides a method of manufacturing the novel hypoallergenic and non-irritant skin care formulations.

  • Publication number: 20040116531
    Abstract: The invention provides novel water-free medical skin care formulations comprising micronized urea dispersed in a fatty phase. The fatty phase consists essentially of hydrocarbons and is essentially free from ingredients with known allergenic potential such as perfumes or perfume substitutes (fragrances), preservatives, colorings, plant extracts, PEGs, cetylstearyl alcohol, lanolin alcohols, lower alcohols, and proteins, thus being particularly suitable for patients with highly sensitive skin. The formulations of the invention have favorable sensorial properties and are stable for an extended period of time. The formulations are suitable for medical skin care, such as for the treatment of severely affected dry, sensitive skin and for the therapy or therapy support of ichthyosis, psoriasis, and eczema. The invention also provides methods of manufacturing such water-free skin care formulations.
