The disclosure relates to a composition that is designed to be administered to a subject intradermally for treating pigmentless skin or creating a temporary tattoo. The composition comprises particles having a polymeric shell and a core that includes a coloring agent. The particles are in a carrier solution at a concentration that is cosmetically effective to delay the bioabsorbance and/or biodegradation of coloring agent in a subject's skin. Bioabsorbance and/or biodegradation of the particles fades the tattoo until it is no longer visible.

Provided herein are polysaccharide derivatives substituted (a) at a degree of substitution (DS1) of at least 0.05 by a fluorescent group (FG) having a mono or polycyclic ring system including at least one heteroatom selected from N, O and S and conjugated double bonds, and having an absorption band in the UV region of light and an emission band in the visible region of light, and bonded via a first linker to any one of the native functional groups of the polysaccharide repeating units; and (b) at a degree of substitution (DS2) of at least 0.05 by a charged group (CG) bonded via a second linker to any one of the native functional groups of the polysaccharide repeating units.

The present application relates processes that can be used to produce encapsulated benefit agents comprising a core and a shell that encapsulates said core, encapsulated benefit agents produced by such process and products comprising such encapsulated benefit agents as well as methods of making and using such products. Such process can be used to produce particles that offer the desired protection and release benefits when used in a varity of products.

This invention provides a groundbreaking approach to PLNPs and their preparation. In particular, the synthetic methodology disclosed herein fundamentally differs from the traditional solid-state annealing reactions that require extreme and harsh reaction conditions. In one unique aspect of the invention, a simple, one-step mesoporous template method utilizing mesoporous silica nanoparticles (MSNs) is disclosed that affords in vivo rechargeable NIR-emitting mesoporous PLNPs with uniform size and morphology. In another unique aspect of the invention, the novel synthetic approach is based on aqueous-phase chemical reactions conducted in mild conditions, resulting in uniform and homogeneous PLNPs with desired size control (e.g., sub-10 nm).

A photosensitive microcapsule having a shell encapsulating a core material. The core material can comprise a benefit agent and the shell can comprise a photosensitive polymer. The photosensitive polymer can include one or more photosensitive moieties having a substituted amine and a 1,3 dione moiety. The core material can be released from the photosensitive microcapsule upon exposure to an electromagnetic radiation field selected from the group consisting of infrared radiation, visible light, ultraviolet radiation and mixtures thereof.

The present invention provides a photosensitising composition comprising a mixture of at least one surfactant at least one alcohol; and/or water, with the proviso that when the at least one surfactant is an alcohol, it is different from the at least one alcohol. In particular, the composition may comprise a mixture of glycerol, ethanol and water. Alternatively, the composition may comprise a mixture of polyethylene glycol, ethanol and water. The photosensitising composition may further comprise at least one photosensitising compound. The present invention also provides a method of treating and/or preventing conditions caused by microorganisms in a subject.

The present invention relates to a method and a composition for detecting the presence of arthropods, and/or their eggs, in the hair of the body and/or head of a subject.
