The embodiments relate to titanate crystal particle dispersions, methods of making the dispersions, and compositions and uses thereof. The dispersions and compositions containing the dispersions provide a high coverage to the skin and high near infrared/infrared (NIR/IR) reflectance. The dispersions include optionally surface treated titanate crystals used as cosmetic powders, and a cosmetically acceptable dispersing medium. The dispersions may be useful in cosmetic compositions as a foundation and/or as a composition to correct skin discoloration, and may be used protect the skin from sun exposure.

The embodiments relate to cosmetic powder materials and compositions containing them that provide a high coverage to the skin and high near infrared/nitrated (NIR/IR) reflectance. The compositions include optionally surface treated titanate crystals used as cosmetic powders, and a cosmetically acceptable carrier. The compositions may be useful as a foundation and/or as a composition to correct skin discoloration, and may be used protect the skin from sun exposure.

This invention relates to a cosmetic composition comprising, in a physiologically acceptable medium, at least one microcapsule comprising at least: —a core, —a first laminated coating surrounding said core comprising at least 45% by weight of the total weight, of a microcapsule of multilayer interference particles comprising at least one iron oxide, and —a second laminated coating surrounding said first coating, comprising between 10 and 40% by weight of titanium dioxide relative to the total weight of a microcapsule, said multilayer interference particles being released from said microcapsule(s) only when said composition is applied on a keratin material such as keratin fibers or the skin.

A non-pyrogenic preparation containing nanoparticles synthesized by magnetotactic bacteria for medical or cosmetic applications. The nanoparticles are constituted by a crystallized mineral central part including predominantly an iron oxide, as well as a surrounding coating without material from the magnetotactic bacteria.

A storage-stable solid composition comprising a tooth whitening effective amount of a particulated inorganic salt of peroxymonosulfate, and a particulated drying agent.

The invention relates to an additive for a powder material intended for compaction into shaped bodies. The additive is used to influence the powder material with regard to its cohesion and slidability on foreign surfaces and comprises as the main constituent one or more polyglycerol fatty acids, each obtained by way of a complete or partial esterification of a linear or branched polyglycerol containing two to eight glyceryl units with one or more fatty acids, each containing 6 to 22 carbon atoms.

This invention provides a material that is capable of preparing an external composition that achieves high smoothness and low roughness and that reflects near-infrared rays. Specifically, a granular composite comprising keratin and hexagonal plate-shaped zinc oxide particles is provided.

This cosmetic product has extensibility and imparts use feels such as silkiness and smoothness, and further demonstrates excellent soft focus effects, and contains: (A) spherical organopolysiloxane particles of which 90% by mole or more are constituted from organosilsesquioxane units and which have a volume average particle size of 0.1 to 30 μm and an average refractive index of 1.44 to 1.57, and; (B) an oil agent; and one or more selected from (C) a silicone crosslinked product and (D) a silicon resin coating silicon rubber powder.

Metal oxide powder formed of metal oxide particles, in which the metal oxide powder has first metal oxide particles having at least one protrusion portion and second metal oxide particles, the first metal oxide particles have an average primary particle diameter of 100 nm or more and 1,000 nm or less, the second metal oxide particles have an average primary particle diameter of less than 100 nm, and a fraction of a total mass of particles having a primary particle diameter of less than 100 nm in a total mass of the metal oxide powder is 0.3% by mass or more and 10% by mass or less.

A powdery cosmetic composition in the form of a compacted powder including, in a physiologically acceptable medium, (i) a pulverulent phase including nanocrystalline cellulose, and (ii) a binder phase. Also, the use of the pulverulent phase for the preparation of a cosmetic composition in the form of compacted powder with satisfactory cohesive properties.
