Abstract: A skin tightening composition including about 2 to about 35 wt. % of at least one thickener selected from polyamide-8, styrene ethylene/propylene copolymer, nylon-611/dimethicone crosspolymer, VP/EICOSENE copolymer, fumed silicas, hydrophobically modified silica, silica silylate, clays and a combination thereof; about 1.5 to about 13 wt. % of at least one filler; about 5 to about 45 wt. % of at least one hydrophobic film former; and about 20 to about 85 wt. % of at least one volatile hydrocarbon, wherein a weight ratio of the at least one hydrophobic film former c) to the at least one thickener a) is 1:2 to 8:1 (hydrophobic film former c):thickener a)), and all weight percentages are based on the total weight of the skin tightening composition.

Abstract: The instant disclosure relates to cosmetic compositions that when applied to skin instantaneously and dramatically improve the appearance of the skin. The compositions include volatile hydrocarbon oil; mineral thickening agents; silicone elastomers; and hydrophobic film forming polymers; wherein the weight ratio of the total amount of hydrophobic film forming polymers to the total amount of mineral thickeners (film forming polymers: mineral thickening agent) is 1:1 to 8:1, and the weight ratio of the total amount of silicone elastomer to the total amount of mineral thickener (silicone elastomer: mineral thickening agent) is 1:1 to 5:1. Methods for improving the appearance of skin comprising application of the cosmetic compositions to the skin are also disclosed.

Abstract: The present invention relates to a fluorescent particulate material, formed from particles of an oxide of an element M, some of the atoms M of which bear a cationic group of formula (I) all or some of said cationic radicals of formula (I) being combined ionically with an anionic form of an organic compound A, which is fluorescent in the visible region, said anionic form of an organic compound A bearing at least one sulfonate group and/or at least one carboxylate group.

Abstract: An optical device is for receiving light from a light source, the light source having an emission wavelength. The optical device includes an elongated light guide, a first end of the light guide configured to receive light from the light source; and a phosphor disposed on a second end of the light guide, an excitation wavelength of the phosphor substantially similar to the emission wavelength of the light source. The light guide is formed of a material configured to dissipate at least some heat generated by the light source.

Abstract: An apparatus for providing light to molecules of a specimen in a fluorescence microscope includes a light emitting diode and an optical element including a phosphor. The molecules have a peak excitation wavelength. The LED emits light at a first wavelength; the phosphor is capable of receiving the light at the first wavelength and emitting light at a preselected second wavelength different than the first wavelength. The second wavelength is substantially similar to the peak excitation wavelength of the molecules.
