[di(3-methylidene-10-camphosulfonic)] acid, optionally either partially or totally neutralized,
together with a photoprotecting synergistically effective amount of (ii) a benzotriazole-substituted
polyorganosiloxane, in a cosmetically acceptable vehicle, diluent or carrier therefor.
US Patent No: 5753241
Transparent nanoemulsion less than 100 NM based on fluid non-ionic amphiphilic lipids and use in
cosmetic or in dermopharmaceuticals
An oil-in-water nanoemulsion in which the oil globules have a mean size of less than 100 nm and
which contains an amphiphilic lipid component containing at least one non-ionic amphiphilic lipid
which is liquid at an ambient temperature of less than 45.degree. C. The nanoemulsion can be used
in the fields of cosmetics and dermopharmaceuticals. The nanoemulsion is stable on storage, can
contain significant amounts of oil while retaining good transparency, and can contain heat-sensitive
active agents.
US Patent No: 5756110
Method for preparing storage-stable, ultrafine oil-in-water emulsion nanopigmented sunscreen/cosmetic
compositions
Stable and homogeneous, topically applicable sunscreen/cosmetic compositions well suited for the
photoprotection of human skin and/or hair against the damaging effects of UV-A and/or UV-B
irradiation, particularly solar radiation, and which display excellent transparency on the skin,
comprise a storage-stable, ultrafine oil-in-water emulsion of a photoprotecting effective amount of
homogeneously and finely dispersed particulates of at least one inorganic nanopigment which
comprises a metal oxide, for example titanium dioxide, wherein the average particle size of the
globules comprising the oily phase of the emulsion characteristically range from 100 nm to 1,000
nm.
US Patent No: 5759563
Liquid delivery compositions
Improved biocompatible liquid delivery compositions, which are useful for the formation of
sustained release delivery systems for active agents, are provided. The compositions include liquid
formulations of a biocompatible polymer or prepolymer in combination with a controlled release
component. The controlled release component includes an active agent. These compositions may be
