The present invention relates to a composite pigment comprising at least one small particle with a mean particle size of more than 100 nm and less than 1 m, preferably less than 600 nm, and more preferably less than 400 nm, wherein the surface of the small particle is at least in part covered with at least one layer comprising at least one inorganic solid UV filter and/or at least one coloring pigment. The composite pigment can be prepared by a method comprising a step of subjecting the small particle and at least one inorganic solid UV filter and/or at least one coloring pigment to a mechanochemical fusion process such as a hybridizer process. The composite pigment can be advantageously used as a component for a cosmetic composition.

Zinc oxide compositions and methods for applying anti-reflective coating on oxide particles for sunscreen applications are provided herein. A composition includes multiple zinc oxide particles suspended within a medium forming sunscreen composition, and two or more coating materials applied to each of the multiple zinc oxide particles in distinct layers via a gradation based on refractive index, wherein each of the coating materials has a refractive index that is between the refractive index of air and the refractive index of zinc oxide.

Zinc oxide compositions and methods for applying anti-reflective coating on oxide particles for sunscreen applications are provided herein. A method includes selecting one or more coating materials to be applied to zinc oxide particles in a sunscreen composition, wherein said selecting is based on optical properties of the coating materials, wherein the optical properties comprises at least the refractive index of each of the coating materials, and applying the selected coating materials to the zinc oxide particles to create the sunscreen composition. A composition includes multiple zinc oxide particles suspended within a medium forming sunscreen composition, and one or more coating materials applied to each of the zinc oxide particles, wherein each of the coating materials has a refractive index that is between the refractive index of air and the refractive index of zinc oxide, and wherein at least one of the coating materials incorporates a textured surface.

The present invention relates to a process for treating keratin fibers such as the hair using a packaging article comprising i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibres, preferably water-soluble fibres; ii) at least one anhydrous oxidizing composition, preferably in paste or powder form, comprising at least one anhydrous chemical oxidizing agent, preferably in paste or powder form; it being understood that the oxidizing composition is in one of the cavities defined by the envelope i).

An antibacterial and sun-protective powdered solid compact composition with decorative elements, consisting of the following raw materials in percentage by weight: 15% to 25% of aluminum starch octenylsuccinate and/or calcium starch octenylsuccinate; 45% to 65% of a carrier powder; 1% to 10% of an ultraviolet protective agent; 0.1% to 0.5% of an antibacterial agent; 1% to 5% of a non-expandable polymer powder; 5% to 15% of an viscous fluid skin-feel modifier; 0.1% to 7.5% of a plant extract, wherein the solid raw materials have a particle size of 5-50 m, and the raw materials are thoroughly mixed and compressed to form a powdered solid compact composition with a density of 8-9 g/cm.sup.3. The manufacturing process comprising pre-mixing, blending, pulverizing, standing, and compacting under appropriate pressure enables reduced energy consumption and effectively mitigates safety hazards caused by certain flammable materials during production.
