  • Patent number: 5716638
    Abstract: A cosmetic or medical composition for topical application to the skin. It results in the transdermal passage of an active ingredient, or in the introduction of such agent into the skin. The essential components of such compositions are phospholipids, an aliphatic alcohol of three or four carbon atoms or a combination of these alcohols, water and a compatible active ingredient, optionally with propylene glycol. Compositions advantageously comprise from 0.5% to 10% phospholipids, from 5% to 35% of a C.sub.3 - or C.sub.4 -alcohol, 15 to 30% ethanol, which contain together at least 20% but not more than 40 wt. % of ethanol and the C.sub.3 -alcohol; up to 20 wt. % propylene glycol, at least 20% water and at least one active ingredient. The compositions are suitable for the topical application of a wide variety of cosmetic and pharmaceutically active compounds.

  • Patent number: 5540934
    Abstract: A cosmetic or medical composition for topical application to the skin. It results in the transdermal passage of an active ingredient, or in the introduction of such agent into the skin. The essential components of such compositions are a phospholipid, a lower aliphatic alcohol of two to four carbon atoms, optionally with propylene glycol, water and a compatible active ingredient. The alcohol content is generally from 20 to 50%, and when propylene glycol is present, the combined percentage of alcohol and glycol being up to about 70%. The composition are suitable for the topical application of a wide variety of cosmetic and pharmaceutical compounds.

  • Patent number: 4910021
    Abstract: A capsule for oral administration of a pharmaceutically active ingredient contains a pharmaceutical composition comprising the active ingredient, for example, a peptide, an absorption promoter and usually, a carrier. The absorption promoter is capable of enhancing absorption of the active ingredient from the intestine into the bloodstream. The capsule is coated with a film forming composition, which film is sufficiently insoluble at a pH below 7 as to be capable of protecting the capsule and its contents from the digestive juices until the capsule reaches a region below the upper part of the intestine, whereupon the coating and capsule are capable of eroding or dissolving to release the active ingredient for absorption into the bloodstream.
