US Patent No: 6419946
Nanoemulsion based on mixed esters of a fatty acid or of a fatty alcohol, of a carboxylic acid and of a
glycerol and its uses in the cosmetics, dermatological and/or ophthalmological fields
A nanoemulsion, the oil globules of which have a number-average size of less than 100 nm,
comprising a surfactant chosen from mixed esters of a fatty acid or of a fatty alcohol, of a
carboxylic acid and of glycerol and at least one oil having a molecular weight of greater than 400,
the ratio by weight of the amount of oily phase to the amount of surfactant ranging from 2 to 10.
The nanoemulsion may be used in, for example, the cosmetics and dermatological fields, in
particular for moisturizing the skin and/or mucous membranes, as well as for treating the hair, and
in the ophthalmological field, as an eye lotion for treating the eyes.
US Patent No: 6428814
Bioadhesive nanoparticulate compositions having cationic surface stabilizers
Bioadhesive nanoparticulate compositions, comprising active agent particles and one or more
cationic surface stabilizers, are described. The cationic surface stabilizers prevent aggregation of
the nanoparticles and increase bioadhesion of the nanoparticles to biological substrates, such as an
insect, teeth, bone, nails, chitin, feathers, scales, mucous, skin, hair, plant tissue, etc. The particles
may consist of pharmacologically active compounds (e.g., drug compounds for human or
veterinary use), agricultural chemicals (pesticides, herbicides, fertilizers, and the like), cosmetic
agents, consumer products (coloring agents, flavors, or fragrances), or other materials which
function by interacting with biological substrates. In addition, the invention relates to methods of
preparing and using such bioadhesive nanoparticulate compositions.
US Patent No: 6450941
Device for the stimulation of body cells through electromagnetic radiation
The invented device for hair-care consists of an applicator (1), which is equipped with at least one
print-board (6,7), upon which semiconductor-diodes (LED) or laser-diodes (8) are placed. The
semiconductor-diodes (LED) and the laser-diodes radiate light with a wavelength between 350 and
1200 nm. Further, the applicator (1) contains one or more plain transmitter-coils (transducers) (3)
for the emission of pulse-shaped electromagnetic radiation. It can be equipped with an IR-heating
element and a ventilator to produce a warm air stream. The applicator (1) can be formed as a hood
(2) or designed as a plainer surface applicator consisting of one or more parts, in the latter case the
