Disclosed is a composition comprising at least one core-shell microcapsule in a suspending medium. The microcapsule comprises a core and a shell around said core. The shell comprises a hyperbranched polysaccharide selected from the group consisting of amylopectins, dextrins, hyperbranched starches, glycogen and phytoglycogen and mixtures thereof.

A W/O/W emulsion composition comprising a large amount of silicone oil and having a high viscosity and a high stability is provided.

The W/O/W emulsion composition comprises: an inner aqueous phase; an oil phase in which the inner aqueous phase is dispersed; and an outer aqueous phase in which the oil phase is dispersed,
wherein the inner aqueous phase comprises an osmotic pressure regulator that prepares the inner aqueous phase to have a higher osmotic pressure than the outer aqueous phase, the oil phase comprises a silicone oil that is 0.5 times by mass or greater of the total oil phase, and a silicone-based surfactant having a silicone skeleton as a main skeleton and a hydrophilic group in a side chain, and the outer aqueous phase comprises a polyol and an alkyl-modified carboxyvinyl polymer.

A method for making a composition for enamel regeneration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions stabilized by solid particles, and add them to a toothpaste, enamel restoring gel or mouth wash base. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste, enamel restoring gel or mouth wash over a long period of time. When the toothpaste, enamel restoring gel or mouth wash of the present disclosure is used in oral cavity, the water-in-oil-in-water emulsions rapture under the effect of friction and pressing, releasing the soluble calcium and phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of enamel remineralization.

The invention described herein is related to the preparation and usage of nanoemulsions and nanoparticles which containing biological active ingredients including cosmetic, medical and pharmaceutical active ingredients to pass skin barriers and promote cell growth with evident clinical effects. Also, the present invention contains a cosmetic formulation that can be used for skin rejuvenation, wrinkle removal, scar treatment and wounds healing.

Provided is a water-in-oil-in-water (W/O/W) emulsion cosmetic composition prepared by mixing an oil-in-water emulsion and a water-in-oil emulsion, wherein the W/O/W emulsion cosmetic composition has excellent feel of use and moisturizing feel while having excellent emulsion stability even under various temperature conditions, and has an excellent absorption rate of an active ingredient on the skin.

A method for making a toothpaste enabling enamel restoration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste over a long period of time without causing precipitation of calcium phosphate. When the toothpaste of the present disclosure is used in brushing teeth, the water-in-oil-in-water emulsions are ruptured under the effect of friction and pressing, releasing the soluble calcium and/or phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of remineralization of enamel and/or dentin exposed to the oral cavity.

Succinic acid esters of resveratrol and topical compositions containing the esters.

This invention relates to a composition in the form of a water-in-oil emulsion that comprises an aqueous phase dispersed in a continuous oily phase, wherein the continuous oily phase comprises: at least one organo-modified clay, with a content by weight ranging from 0.5% to 1% relative to the total weight of said composition; at least one silicone elastomer powder coated with a silicone resin, with a content by weight ranging from 5% to 12% relative to the total weight of said composition; and at least one silicone surfactant with a content by weight ranging from 1.4% to 3% relative to the total weight of said composition; and wherein the dispersed aqueous phase comprises: water at a content by weight ranging from 15% to 25% relative to the total weight of said composition; and ethanol at a content by weight ranging from 8% to 18% relative to the total weight of said composition.

An emollient composition comprising at least one hydrocarbon fluid in an amount of 50 to 100% by weight relative to the total weight of the composition is provided. The fluid can be obtained by a process of catalytically hydrogenating a feed comprising more than 85% by weight of oligomerized olefins, at a temperature from 115 to 195° C. and at a pressure from 30 to 70 bars. A cosmetic, dermatological or pharmaceutical composition comprising the emollient composition and uses thereof are also provided.
