The present invention relates to a sunscreen formulation which exhibits superior ultraviolet
protection and water resistance than prior art sunscreen compositions. The sunscreen formulation
comprises (a) a dispersion comprising a sunscreen active agent and (b) a base composition
comprising a rheological modifying agent and water. The sunscreen formulation is substantially
free of surfactants. According to a preferred embodiment, the sunscreen active agent is
ethylhexylmethoxycinnamate, butylmethoxydibenzoylmethane, or a combination thereof. The
sunscreen formulation preferably comprises a phosphorylated starch derivative as a rheological
modifying agent. Another embodiment of the present invention is a method of protecting skin or
hair from ultraviolet radiation by applying an effective amount of the sunscreen formulation of the
present invention to the skin or hair.
US Patent No: 7182938
Cosmetic formulations comprising ZnO nanoparticles
The present invention relates to the formation of surface treated zinc oxide and titania particles, and
in particular zinc oxide and titania nanoparticles, with a siloxane star-graft copolymer coating,
comprising a looped and/or linear polymeric structure on a star-graft copolymer coating, on a
particle surface to control the interfacial surface interactions between the particle and the oil phase
of the cosmetic skin formulation.
US Patent No: 7184614
Method and apparatus for improving safety during exposure to a monochromatic light source
A method and apparatus are disclosed for improving bodily safety during exposure to an eye
hazardous monochromatic treatment light source by diverging the light, such as with a diffusing
unit attached to the light source distal end so that the radiance of the light exiting the distal end is
an eye safe level. At a first position of the light source distal end substantially in contact with an
outer surface of a target, the energy density of an exit beam from the distal end is suitable for
effecting a desired treatment, and at a second non-contact position of the distal end the exit beam
energy density is significantly less than a value suitable for effecting the treatment. In an additional
embodiment, the diverging or diffusing unit has a device for evacuating vapors or particles from the
target.
