The present invention relates to a cosmetic composition for making up and/or caring for the skin and/or the lips, including, in a physiologically acceptable medium, at least one oil, which is preferably non-volatile, at least hydrophobic silica aerogel particles, at least one hydrocarbon-based block copolymer, preferably obtained from at least one styrene monomer, the said composition comprising less than 5% by weight of water relative to the total weight of the composition, and preferably being anhydrous.

Hair spray compositions comprising a liquid carrier, hollow, fluid-filled microspheres, a polymer fixative, and propellant are provided.

A pharmaceutical or cosmetic composition, comprising a substantially poorly water-soluble pharmaceutical active ingredient; and a nanoporous folic acid material, wherein the active pharmaceutical ingredient is incorporated inside the nanoporous channels of the particles.

Processes for drying gel particles, in particular for producing aerogels, involve providing a suspension containing gel particles and a solvent, introducing the suspension into a column where carbon dioxide flows in countercurrent, and removing dried aerogel particles from the column. The suspension is introduced in the top region of the column and dried aerogel particles are removed in the lower region. Pressure and temperature in the column are set such that the mixture of carbon dioxide and solvent is virtually supercritical or is supercritical. The aerogel particles can be discharged via discharge vessels or continuous decompression. Aerogel particles can be obtained by such a process and the aerogel particles can be used for medical and pharmaceutical applications, as additive or carrier material for additives for foods, as catalyst support, for cosmetic, hygiene, washing and cleaning applications, for production of sensors, for thermal insulation, or as a core material for VIPs.

The invention relates to an antimicrobial particle and to a composition for use in personal or home care products comprising the same. The invention also relates to a process for preparing the antimicrobial particle. The antimicrobial particle comprises thymol and terpineol incorporated in a cage-forming inorganic silicate or aluminosilicate particle which is coated with a coating material selected from a water soluble alkali or alkaline earth metal salt.

The invention relates to a composition, notably a cosmetic and/or dermatological composition, in particular for caring for a keratin material, notably the skin and in particular facial skin, which is in the form of an oil-in-water, O/W, emulsion, and comprising at least a) particles of at least one hydrophobic silica aerogel, b) an ester hydrocarbon-based oil, and c) an ether hydrocarbon-based oil, in which said ether and ester oils are present in an ether oil/ester oil weight ratio ranging from 1 to 2.

Compositions that include benefit agent delivery particles, the particles having a core and a shell encapsulating the core, the shell including certain acrylate-based polymers. Processes for making and using such compositions.

Proteinaceous cellulose microparticles are provided. These microparticles comprise cellulose nanocrystals and one or more peptide, one or more protein, or a mixture thereof, wherein the nanocrystals and the peptide(s) and/or protein(s) are aggregated together to form the microparticles. In embodiments, the microparticles comprise silk fibroin and advantageously are hydrophobic and lipophilic. There are also provided cosmetic preparations comprising these microparticles. In advantageous embodiments, these cosmetic preparations comprise a water-in-oil emulsion or a lipophilic medium. Finally, there are also provided methods of producing the microparticles.

The present invention relates to a cosmetic composition comprising inorganic particles for blocking blue light, containing inorganic particles having a blue light blocking effect as an active ingredient in the composition, reflecting and scattering light in a blue light wavelength range, thereby significantly blocking light of a blue light area that has otherwise been difficult to block conventionally.

The present disclosure provides porous composite powder which includes biodegradable polymer particles with a porous structure having positive charges dispersed uniformly thereon and further includes inorganic particles. The porous composite powder adsorbs and removes fine particulate matter remaining in the skin and skin pores effectively through ionic bonding, while maintaining a spherical shape. The present disclosure also provides a method for preparing porous composite powder for adsorption of fine dust including particles forming a composite homogeneously, while maintaining a spherical shape, through a single process.
