The invention discloses an anti-dandruff shampoo composition, which comprises the following components in percentage by weight: 5.0 to 50.0 percent of surfactant, 0.01 to 10.00 percent of unsaturated fatty alcohol (acid) ester, 0.1 to 5.0 percent of anti-dandruff agent, and the balance of carrier containing water, wherein the anti-dandruff agent is a composition of a non-hydrophilic particle anti-dandruff agent and a hexamidine derivative. The anti-dandruff shampoo composition uses the unsaturated fatty alcohol ester which has good compatibility with both scalp sebum and the non-hydrophilic particle anti-dandruff agent so that the active components of the non-hydrophilic anti-dandruff agent pass through the scalp sebum preferentially to directly act on oleophilic microorganisms in the scalp, and simultaneously the active components are combined with the hexamidine derivative to control the microorganisms from a water phase path, so the anti-dandruff shampoo composition achieves the same anti-dandruff effect with a low addition of the anti-dandruff agent, reduces the environmental pollution, and has an obvious effect of improving the hairline brightness of hair.

The invention discloses a method for revealing and extracting a scene potential fingerprint. The method is characterized by comprising the following steps of: 1, irradiating a short-wave ultraviolet laser light which has a wavelength of 266 nm and is output by a neodymium doped yttrium aluminium garnet (ND-YAG) ultraviolet laser serving as a light source to a detection material on which the potential fingerprint is reserved; 2, filtering environmental parasitic lights by using a band-pass glass filter with the central wavelength of 266 nm, and transmitting a laser image of 266 nm reflected onthe detection material to an ultraviolet camera; and 3, receiving and recording the laser image with the wavelength of 266 nm transmitted by the band-pass glass filter by the ultraviolet camera.

The invention discloses a Chinese herbal whitening composition, a facial mask and a preparation method of the facial mask. The Chinese herbal composition comprises the following main components: pearl, borax, amber, aloe powder, panthenol, nutmeg kernel oil, trehalose, a sargassum fusiforme extract, a safflower extract, a licorice root extract, a tribulus terrestris fruit extract, a paeonia suffruticosa root extract, an extract of the root and stem/ root of medicinal solomonseal rhizome and zinc carbonate hydroxide. A mask pasting carrier is soaked into a herbal liquid of the Chinese herbal composition so as to form a facial whitening mask. The main components in the formula are prepared by virtue of a Chinese herb superfine pulverizing technology, so that the Chinese herbs are micronized and can easily penetrate through the mucosa of skin. Thus, the whitening effect is obvious after the facial whitening mask is used. The facial whitening mask has good abilities of inhibiting melanin and increasing skin brightness and a good moisture preserving effect, and has a strong moisturizing effect and a persistent water locking effect. Meanwhile, the facial whitening mask is safe and non-irritant and cannot perform an adverse reaction on a human body.

Disclosed herein is a light guide plate formed by injection molding of an aromatic polycarbonate resin that is a polymer of an aromatic dihydroxy compound and a diaryl carbonate. The aromatic dihydroxy compound and the diaryl carbonate are present in a mole ratio of about 1:1.02 to about 1:1.35, and the aromatic polycarbonate resin has a weight average molecular weight from about 10,000 g/mol to about 18,000 g/mol and includes about 5 mol % to about 30 mol % of terminal hydroxyl groups relative to total moles of terminal groups. The light guide plate formed of the aromatic polycarbonate resin can reduce a yellowing phenomenon upon injection molding, can exhibit low color deviation under high temperature and high humidity conditions, and can secure excellent properties in terms of discoloration resistance, and brightness quality (brightness uniformity), and the like.

An AlGaInP light emitting diode with improved illumination is provided. The AlGaInP light emitting diode includes a semiconductor substrate, a light re-emitting layer, an AlGaInP layer with a first doping concentration, an AlGaInP lower cladding layer with a second doping concentration less than the first doping concentration, an undoped AlGaInP active layer, an AlGaInP upper cladding layer, a window layer, an annular-shaped top electrode on the window layer and a layered electrode on a bottom of the semiconductor substrate. The light re-emitting layer includes at least a first region formed of the light re-emitting layer and a second region formed of Al₂O₃ enclosing the first region. Since AlGaInP layer between the AlGaInP lower cladding layer and the light re-emitting layer has the first doping concentration larger than that of the AlGaInP lower cladding layer, the AlGaInP layer provides a transverse current spreading. The Al₂O₃ region also improves light reflection illuminating on the light re-emitting layer. As a result, the brightness performance of the light emitting diode is improved.
