US Patent No: 6562356
Nanoemulsions comprising at least one amphiphilic lipid, at least one oil, and at least one polyethylene
glycol (PEG) ester, and uses thereof
Oil-in-water nanoemulsions comprising oil globules with an average size of less than 150 nm and
comprising at least one oil, at least one amphiphilc lipid, and at least one polyethylene glycol
(PEG) derivative chosen from PEG esters and PEG ethers chosen from compounds of formula (I):
in which: R.sub.1 is chosen from linear and branched, saturated and unsaturated alkyl groups
comprising from 8 to 30 carbon atoms and linear and branched, saturated and unsaturated acyl
groups comprising from 8 to 30 carbon atoms, R.sub.2 is chosen from a hydrogen atom, linear and
branched, saturated and unsaturated alkyl groups comprising from 1 to 30 carbon atoms, and linear
and branched, saturated and unsaturated acyl groups comprising from 1 to 30 carbon atoms, and n
is a number ranging from 80 to 350. Processes comprising such oil-in-water nanoemulsions.
US Patent No: 6572892
Cosmetic or dermopharmaceutical composition in the form of beads and methods for preparing same
The invention concerns an anhydrous solid composition comprising at least a hydrophobic wax, an
oil and talcum, having preferably the form of beads with size ranging from 1 to 10000 microns. The
beads can contain a cosmetic or pharmaceutical active principle, pigments or an agri-food
constituent. The invention also concerns the method for preparing said beads.
US Patent No: 6593706
High pressure neon arc lamp
A high pressure neon arc lamp and method of using the same for photodynamic therapies is
provided. The high pressure neon arc lamp includes a housing that encloses a quantity of neon gas
pressurized to about 500 Torr to about 22,000 Torr. At each end of the housing the lamp is
connected by electrodes and wires to a pulse generator. The pulse generator generates an initial
pulse voltage to breakdown the impedance of the neon gas. Then the pulse generator delivers a
current through the neon gas to create an electrical arc that emits light having wavelengths from
about 620 nanometers to about 645 nanometers. A method for activating a photosensitizer is
provided. Initially, a photosensitizer is administered to a patient and allowed time to be absorbed
into target cells. Then the high pressure neon arc lamp is used to illuminate the target cells with red
light having wavelengths from about 620 nanometers to about 645 nanometers. The red light
activates the photosensitizers to start a chain reaction that may involve oxygen free radicals to
