US Patent No: 5658555
Photoprotective/cosmetic compositions comprising synergistic admixture of sunscreen
compounds/nanopigments
Topically applicable sunscreen/cosmetic compositions well suited for enhanced photoprotection of
human skin and/or hair against the damaging effects of UV-A and UV-B irradiation, particularly
solar radiation, comprise a photoprotecting synergistically effective amount of (i) 2,4,6-tris[p-((2'ethylhexyl)oxycarbonyl)anilino]-1,3,5-triazine
and benzene-1,4-di(3-methylidene-10camphorsulfonic)acid,
optionally either partially or totally neutralized, together with
photoprotecting synergistically effective amounts of (ii) particulates of at least one inorganic
nanopigment which comprises a metal oxide, in a cosmetically acceptable vehicle, diluent or carrier
therefor.
US Patent No: 5658575
Cosmetic or dermatological composition comprising an oil-in-water emulsion based on oily globules
provided with a lamellar liquid crystal coating
Cosmetic or dermatological compositions comprising an oil-in-water type emulsion containing oily
globules which are coated with a lamellar liquid crystal coating and are dispersed in an aqueous
phase, in which each oily globule contains at least one lipophilic compound which is cosmetically
or dermatologically active and is individually coated with a monolamellar or oligolamellar layer of
at least one lipophilic surface-active agent, at least one hydrophilic surface-active agent, and at least
one fatty acid, the coated oily globules having a mean diameter of less than 500 nanometers,
preferably less than 200 nanometers, and the oily phase contains a basic agent in the dissolved
state, exhibit good skin and hair penetration.
US Patent No: 5662932
Solid fat nanoemulsions
The present invention provides pharmaceutical compositions comprising nanoemulsions of
particles comprising a lipid core which is in a solid or liquid crystalline phase at 25.degree. C.,
stabilized by at least one phospholipid envelope, for the parenteral, oral, intranasal, rectal, or
topical delivery of both fat-soluble and water-soluble drugs. Particles have a mean diameter in the
range of 10 to 250 nm. A wide variety of drugs and oxygen transporting perfluorocarbons may be
encapsulated in the particles. In addition to drug delivery vehicles, the invention provides oxygen
