An improved process of making a benefit agent delivery particle and an improved microcapsule made by such process are disclosed. The process comprises the steps of providing a first composition of water phase 1, water phase 2, water phase 3 and an oil phase, where a water phase multifunctional (meth)acrylate monomer is selected to have a hydrophilicity index of least 25, or even at least 30 and the oil phase multifunctional (meth)acrylate monomer has a hydrophilicity index of 25 or less, or even 20 or less. The water phases comprise water, initiator, a water-soluble or dispersible amine(meth)acrylate or hydroxyl(meth)acrylate, a multifunctional (meth)acrylate and one water phase comprises water, carboxyalkyl(meth)acrylate and a base or quaternary ammonium acrylate. Water phases are combined to prereact the hydroxy- or amine(meth)acrylate and the multifunctional (meth)acrylate to form a multifunctional hydroxyl-amine(meth)acrylate pre-polymer. The pre-polymer is combined with the remaining water phase and an emulsion is formed by emulsifying under high shear agitation, an oil phase comprising a multifunctional (meth)acrylate monomer and a benefit agent core material thereby forming a wall surrounding the benefit agent core material.

A method for preparing non-free radical photo-crosslinked hydrogels includes: dissolving component A that is a polymer derivative modified with o-nitrobenzyl phototrigger in a biocompatible medium to obtain solution A; dissolving component B that is a polymer derivative containing hydrazide, hydroxylamine or primary amine in a biocompatible medium to obtain solution B; mixing solution A and solution B to obtain a precursor solution of hydrogel; under light irradiation, crosslinking aldehyde generated from the o-nitrobenzyl with the hydrazine, hydroxylamine or primary amine to obtain a hydrogel by forming hydrazone, oxime or schiff base, respectively. A kit for preparation and application of the hydrogel in tissue repair, beauty therapy, and cells, proteins or drugs carriers is also described. The method or kit can achieve in situ photo-gelling on tissue surface or in situ forming thin gel on wounds in clinical treatment of wounds.

Exemplary methods and systems can be provided for resurfacing of skin that include formation of a plurality of small holes, e.g., having widths greater than about 0.2 mm and less than about 0.7 mm or 0.5 mm, using a mechanical apparatus. Compressive and/or tensile forces can then be applied to the treated region of skin as the damage heals to facilitate hole closure, and provide enhanced and/or directional shrinkage of the treated skin area.

A film-forming cosmetic composition including, in an aqueous continuous phase, at least one legume starch having an amylose content greater than or equal to 30%, at least two plasticisers selected from polyols and water, it being understood that the polyols are present in a content ranging from 8 to 25% by weight, preferably from 10 to 20% by weight, relative to the total weight of the composition. Also, the use of such a composition for forming, on keratin materials, a peel-off film.

A multicomponent composition for coloration of materials such as keratin fibers, keratin material, keratin textiles including but not limited to hair, eyebrows, eyelashes, skin, nails and animal fiber textiles is disclosed. The multicomponent composition comprises a first component of a CDI link compound having inert or reactive termini and having at least two groups capable of in situ combination with carbodiimide which preferably are acid groups, a second component of a polycarbodiimide terminated by inert or reactive groups, a third component of a polyamine. Optional additional components are also disclosed.

Disclosed herein are cosmetic compositions comprising (a) at least one ethylenically unsaturated polymerizable compound and (b) at least one photoinitiator system comprising at least one photoinitiator having at least one absorption wavelength greater than about 350 nm. Also disclosed herein are methods of making up and/or enhancing the appearance of a keratinous substrate comprising (1) forming at least one film on the keratinous substrate by applying said cosmetic composition to the keratinous substrate and (2) exposing the film to UV-LED radiation.

The invention is directed to a personal care composition which contains a crosslinked ionic silicone network wherein the crosslinked ionic silicone network is formed by the ring-opening polymerization of oxirane moiety.

Disclosed is 1) a method for greatly increasing the solubility of useful actives in siloxane matrix-forming preparations, and 2) the associated preparations, themselves. Volatilizing coagents are utilized to give novel gels containing heretofore siloxane-insoluble additives.

Methods for producing a cosmetic coating on a skin surface, by: (A) electrostatically spraying a composition comprising component (a) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone, and component (b) a polymer having a film-forming ability directly onto the skin to form a coating on the skin surface; and (B) subsequently applying a powder-containing cosmetic on the formed coating, afford cosmetic coatings which can be removed without using a cleansing agent.
