A process for the production of a solid cosmetic preparation is described wherein a wax phase comprising at least one wax, at least one oil, and if applicable, oil-soluble ingredients and solvents are melted, the molten wax phase is mixed with an aqueous phase comprising at least one water-soluble or water-soluble water-dispersible film former and with a w/o emulsifying system until an emulsion is formed, and the resulting emulsion is allowed to cool to form a wax matrix with aqueous phase droplets embedded therein, and the products made therefrom and their use.

Methods for producing cellulose articles having controlled release of active ingredient include dispersing pulp in aqueous direct solvent for cellulose to form a slurry. Organically modified or ion-exchange-activated phyllosilicate is homogenized in a direct solvent for cellulose with exfoliation by shearing, then mixed with the slurried pulp. A mixture of active ingredient and a lipophilic matrix material or a water-in-oil (“W/O”) emulsion containing active ingredient is stabilized with thickener, converted into a gel-like paste, and mixed with the slurried pulp. Water is stripped from the mixture until all cellulose is dissolved, the mixture is formed into shaped articles, and dried. Exemplary active ingredients include cosmetic active ingredients, fat-soluble vitamins or apolar plant extracts. Domains of active ingredient and matrix material or emulsion containing active ingredient are present as fine divisions within the inventive articles. Exemplary shaped articles include functional fibers in knitted, woven and nonwoven fabrics; paper; foils and membranes.

The object is providing a water-in-oil emulsion sunscreen cosmetic having a property not present in the prior art, in which UV protection ability improve upon contact with water, sweat and the like in comparison with that directly after application, and also having pleasant texture and easy to wash off. The present invention provides a water-in-oil emulsion sunscreen cosmetic comprising (A) 6 to 40 mass % of a UV protective agent; (B) an organic-modified clay mineral; (C) an oil-phase-thickening agent, other than (B) and (D) a silicone-based surfactant having an HLB of less than 8, wherein the ratio, [total quantity of component (B) and component (C)]/[total quantity of (E) non-volatile liquid oils except silicone oils], is 0.04 or more and less than 0.68.

A water-in-oil emulsified sunscreen cosmetic including the following components (A1), (A2), (B), and (C), with a content of (D) a non-volatile silicone oil being 0.1 mass % or more and 4 mass % or less, (A1) 5 mass % or more of a hydrophobized titanium dioxide fine particle, (A2) 10 mass % or more of a hydrophobized zinc oxide fine particle, (B) a divalent polyol, and (C) 2 mass % or more and 14 mass % or less of a non-volatile hydrocarbon oil, wherein each mass % is with respect to 100 mass % of the water-in-oil emulsified sunscreen cosmetic.

The instant disclosure relates to a kit comprising two or more separately contained cosmetic compositions that are miscible with one another upon mixing, wherein the two or more cosmetic composition have: (a) a viscosity of at least 1,800 cPs or a storage modulus (G′) greater than the loss modulus (G″) for a viscosity below 1,800 cPs; and (b) a maximum yield stress of 9,000 Pa; and wherein the two or more cosmetic compositions are chosen from: (i) oil in water emulsions; (ii) water in silicone emulsions; and (iii) anhydrous emulsions. Methods for treating skin with the kits and/or the cosmetic compositions are also disclosed.

Topical personal care compositions containing amino acids and 4-substituted resorcinols for potentiating glutathione synthesis within skin cells. The compositions can be used to improve skin appearance of chronological aging or photoaging, resulting from exposure to UV light/sunlight, or environmental pollutants. The compositions are also useful for attaining even skin color and reducing pigmentation, age spots and discoloration.

In a cosmetic composition according to the present invention, a coating membrane with a multilayer lamella structure is formed on the outside of ceramide particles by using phytosphingosine, and therefore, the cosmetic composition is stably present without ceramide precipitation even in formulations with low viscosity as well as high viscosity although the particles contain a high content of ceramide, and a cosmetic composition showing an excellent skin barrier recovery effect can be provided.

A photostable UV-A/UV-B-sunscreen composition is provided. The composition includes an oil in water or water in oil emulsion, wherein the emulsion includes at least one photostabilizer having anti-oxidant properties, at least one SPF booster, and at least one UV-A filter and at least one UV-B filter. The UV-A/UV-B sunscreen composition is provided in which the composition is essentially free of oxybenzone.

Provided in various embodiments are compositions for topical application to the skin of a mammal, methods for their preparation, and their uses in skin care compositions to reduce adhesion of unwanted particles to the skin. When a hydrophobic non-volatile solvent and a hydrophobic non-volatile high melting point material with a melting point in the range of 60° C. and 100° C. are combined with a hydrophobic volatile solvent which compatibilizes the hydrophobic non-volatile solvent and the hydrophobic non-volatile high melting point material and the hydrophobic non-volatile high melting point material is selected to be at least partially incompatible with the hydrophobic non-volatile solvent in the absence of the hydrophobic volatile solvent, the resulting composition may be applied to skin to reduce adhesion of unwanted particles to the skin.
