The present invention provides a method for easily and simply producing a zinc oxide phosphor that has a high level of safety and a high emission intensity and is useful for, for example, cosmetic applications. The present invention also provides a zinc oxide phosphor having such excellent physical properties and a cosmetic product containing the same. Provided is a method for producing a zinc oxide phosphor, including: a raw material mixing step of mixing an oxygen-containing zinc compound and a sulfur-containing compound; and a firing step of firing the raw material mixture obtained in the raw material mixing step, the firing step including firing in a reducing atmosphere followed by firing in an oxygen-containing atmosphere.

Use of anthraquinone dyes and of fluorescent dyes for dyeing keratin fibres, dyeing process and composition. The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, using a) one or more particular anthraquinone dyes and b) one or more fluorescent direct dyes; to a composition comprising a) and b). The present invention also relates to a multi-compartment device containing the compounds defined above.

A topical antimicrobial composition includes a lipophilic component including a surfactant system with an HLB value of less than 10; an amphiphilic component including an antimicrobial compound; an aqueous hydrophilic component; and a fluorescent material. The composition includes less than 10 wt % of lower monohydric alcohols based on the total weight of the composition. The composition is in the form of a microemulsion at room temperature with a disperse phase having droplets with a particle size of 5 nm to 400 nm.

The present disclosure provides biophotonic topical compositions, kits and their uses. In some aspects, the biophotonic topical compositions of the present disclosure comprise a first chromophore, a salt selected from one or more bicarbonate or carbonate salts or a combination of the foregoing salts, and one or more gelling agents. In some aspects, the biophotonic topical compositions of the present disclosure comprise a first chromophore, one or more polyols, and one or more gelling agents. The biophotonic compositions of the present disclosure do not include an oxidant selected from the group consisting of a peroxide, a peroxy acid, hydrogen peroxide, carbamide peroxide, an alkali metal peroxide, an alkali metal percarbonate, peroxyacetic acid, and an alkali metal perborate. The biophotonic compositions are useful for promoting wound healing and skin rejuvenation, as well as treating acne and various skin disorders.

The present disclosure provides biophotonic topical compositions and methods useful in phototherapy. In particular, the biophotonic topical compositions of the present disclosure are substantially resistant to leaching such that very low amounts of chromophore(s) present in the biophotonic composition leach out of the composition. The biophotonic compositions and the methods of the present disclosure are useful for promoting wound healing and skin rejuvenation, as well as treating acne and various skin disorders.

The present disclosure relates to a plaque disclosing composition containing riboflavin 5-phosphate sodium, a method for disclosing a plaque, wherein the plaque is an acquired pellicle, and a method for collecting and analyzing an information about the amount and characteristics of dental plaque by analyzing the color and intensity of fluorescence emitted by riboflavin 5-phosphate sodium for effective treatment of dental plaque even at the early stage.
