Described herein are oral care compositions comprising metal silicates (e.g. sodium silicate); along with methods of making and using same.

A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms.

Provided are personal care compositions comprising a core polymer, at least one inner shell polymer, and an outer shell polymer providing SPF boosting and opacity, wherein the core polymer comprises polymerized units derived from monoethylenically unsaturated monomers containing at least one carboxylic acid group and non-ionic ethylenically unsaturated monomers, and the inner and outer shell polymers comprise polymerized units derived from non-ionic ethylenically unsaturated monomers and aliphatic monomers selected from the group consisting of allyl acrylate, allyl methacrylate, and mixtures thereof.

An inedible and dry dormant state encapsulated probiotic core-shell particle for external, non-mucosal skin application is provided. From inside out, the core-shell particle has a structure of a carrier particle core serving as a nutrient source for probiotics, a first layer including a dormant probiotic species for affecting epidermal biome and at least one prebiotic as a food source for the probiotic, a polymer layer positioned over the first layer, and a dissolvable protective layer for protecting the probiotic core-shell particle from oxidation, heat and humidity. By co-applying with a releasing medium, the dissolvable protective layer and the polymer layer are dissolved to expose the dormant probiotic containing layer, the first layer. Further, the releasing medium also is able to activate and reconstitute the dormant probiotic to a live probiotic on the applied non-mucosal epidermal surface.

The present invention relates to a method for producing a multi-capsule, the method including steps of: (a) preparing a coating solution by mixing purified water, titanium dioxide, mica, a hydrophobic polymer, cellulose gum, and sucrose; and (b) drying the coating solution prepared in step (a) while spraying the coating solution through a spray nozzle of a fluid bed dryer after introducing a spherical seed of a colorant component for a cosmetic; or a starch or sucrose spherical seed coated with a functional component into the fluid bed dryer, a multi-capsule produced by the method, and a cosmetic composition containing the multi-capsule as an active component.

A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms.

A method of manufacturing a series of capsules (1A) comprising a core (3), and a gelled envelope (5) completely encapsulating the core and comprising at least two external phases (5A, 5B), wherein the gelled envelope has a external surface comprising at least two distinct portions (7A, 7B) formed respectively by the two external phases, and comprising the following steps: conveying a first flow (F1) that is intended to form the core, and a second flow (F2) of at least the two external phases that are intended to form the gelled envelope, wherein each external phase contains a liquid polyelectrolyte that is able to gel, at least one of the two external phases comprising a coloring agent, while the second flow surrounds the first flux about an axis (D2); successive formation of a plurality of liquid bodies (57) comprising a drop (107), and a film coating (109) coating the drop and having the two external phases, wherein the film has on its external surface at least two portions (109A, 109B) formed by the two external phases; and immersing each liquid body in a gelling solution (100) adapted to react with the polyelectrolyte of each of the two external phases, and recovering of the plurality of capsules.

Series of capsules, cosmetic composition containing the capsules and cosmetic treatment using the composition.

There has been a demand for a hair treatment composition that has a long-lasting effect and ensures safety for the purpose of improving hair quality in hair straightening, dyeing, and bleaching, improving hair quality in a wave perm and a straight perm, shampooing, and hair treatment.

The present invention provides a hair treatment composition that contains, as an active ingredient, a complex composed of a dicarboxylic acid and a thiol, in which the dicarboxylic acid is one or more selected from adipic acid, muconic acid, and cosmetically acceptable salts thereof. Further provided is a method for treating hair using the hair treatment composition.

The present invention relates to dust-free preparations dispersible in cold water. These preparations consist of particles comprising water-insoluble or only sparingly water-soluble active substance(s), said particles being coated with one or more layers, the outermost layer comprising as principal component one or more hydrophobic powdering agents on which at least one dispersant is absorbed. The invention also relates to a process for producing these particles and to the use thereof in food supplements, foodstuffs, animal feeds, personal-care products, and medicaments.
