A packaged LED array for high temperature operation comprises a metal base, the metal base including an underlying thermal connection pad. One or more layers of ceramic overly the metal base. The array includes a plurality of LED die, each LED die having electrodes. And, the LED thermally coupled to the metal base. A driver circuit is electrically connected to the LED die electrodes and controls the LED array current. An LED driver is mounted within the LED array package, and thermally coupled to the metal base. In a second embodiment, one or more of the LED die can be switched from the driver to a measurement circuit and used as a photodetector to measure the light output of the LED array. The measured photodetector signal can further be used as a feedback signal to control the LED array light output.

The present invention is directed to fluid fabric enhancing compositions and processes of making and using same. Such fluid fabric enhancing compositions have a desirable fabric enhancer active efficiency that is, at least in part, due to the particle index of such fluid fabric enhancing compositions. Certain chemical processing and physical processing methods are not required to produce such compositions.

Fabric care compositions

A triacylglycerol-based wax includes a triacylglycerol component and a polyol fatty acid partial ester component. The triacylglycerol-based wax may have a melting point of about 54° C. to 63° C., may have an Iodine Value of about 20 to 40, and may have a fatty acid profile including about 50 to 70 wt. % saturated fatty acids. The wax may be suitable for use as a candle.

The invention provides species of lipid, protein, and/or cationic molecule coated active agents and compositions comprising the coated particles. The compositions can be personal care compositions such as anti-dandruff shampoo or conditioner, skin care compositions, creams, gels, toothpastes, mouth washes, and chewing gums.

Coated particles and compositions comprising same

The present disclosure provides compositions suitable for delivering lipophilic bioactive agents. The compositions may be utilized to treat numerous diseases and conditions that would benefit from the application of a lipophilic bioactive agent.

Topical formulations having enhanced bioavailability

An emulsifier mixture for use in a wax-based opacifier composition is comprised of: (a) an alkyl and/or alkenyl oligoglycoside; (b) a fatty acid partial glyceride and optionally (c) at least one amphoteric surfactant, with the proviso that the ratio by weight of (a) and optionally (c) to (b) is between 6:1 and 3:1 and wherein the composition is free from anionic surfactants.

Low-viscosity opacifiers without anionic surface-active agents

The use of nanoscale hair colorants, with a particle diameter in the range of 10 to 500 nm for production of hair colorant preparations is disclosed.

Use of nanoscale hair colorants

The invention relates to nanoscale active anti-dandruff ingredients having a particle diameter ranging from 10 -500 nm in the production of hair-cosmetic preparations.

Use of nanoscale active anti-dandruff ingredients

The invention relates to the use of nanoscalar, cationic compounds with particle diameters of between 10 and 300 nm for producing cosmetic and/or pharmaceutical preparations.

Use of cationic compounds

Disclosed are cosmetic preparations that consist of a continuous phase and active agents dispersed therein and are characterized in that the continuous phase consists of pearly luster waxes.
