A nanoparticle comprising a keratin polypeptide and at least one lipophilic active ingredient, wherein the at least one lipophilic active ingredient is non-covalently bound to the keratin polypeptide and can be e.g. a therapeutic or diagnostic agent, a nutraceutical, a cosmetic ingredients, a dye or a cosmeceutical, the keratin polypeptide being water-soluble; optionally, the nanoparticle further comprises at least one hydrophilic active ingredient non-covalently bound to the keratin polypeptide, which can be e.g. a therapeutic or diagnostic agent, a nutraceutical, a cosmetic ingredients, a dye or a cosmeceutical.

The present invention deals with organic cosmetic active molecules encapsulation into temperature-responsive and pH-responsive oligo(ethylene glycol)-based biocompatible microgels that are incorporated into cosmetic compositions for controlled delivery on skin or hair.

Compositions and methods of manufacture for an extended time-release fragrance comprising volatile organic compounds. A composition of the disclosure includes an effective amount of a volatile organic compound for providing a fragrance that can be sensed by a user and fractionated coconut oil comprising caprylic acid and capric acid.

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

Provided is a cosmetic composition including organic-inorganic composite particles for blocking near-infrared rays. When the cosmetic composition for blocking near-infrared rays according to the present disclosure is applied to skin, light in the near-infrared region may be significantly blocked. The cosmetic composition may be used as a multifunctional product in combination with a UV-blocking material to block a wide range of wavelengths adversely affecting the skin, thereby preventing skin aging.

A process for preparing microcapsules has an interconnected porous microsphere matrix The matrix includes at least one metal oxide and/or inorganic polymer. The microcapsules are obtained by a sol-gel process which involves preparing a first solution being a water-in-oil emulsion and adding to the emulsion a second acidic aqueous pre-hydrolyzed metal precursor solution and/or an organic polymer solution.

Spherical polyester-based resin particles characterized in that the spherical polyester-based resin particles contain a polyester-based resin and have a crystallinity of 20% or less and an average circularity of 0.96 or more. The spherical polyester-based resin particles according to the present invention can provide suitable resin particles as compounding agents for cosmetics such as foundation, antiperspirants, and skin scrubs; various agents such as matte coating agents for paints, rheology modifying agents, antiblocking agents, slipperiness-imparting agents, light diffusion agents, electroconductive agents, and diagnostic testing agents for medical use; and additives to molded articles such as automobile materials and construction materials.

Provided are methods, compositions and kits employing cellulose nanocrystals for hair-straightening treatment. Also provided are methods, compositions and kits employing a resilin, for hair-straightening treatment and/or for maintenance of straightened hair following a hair-straightening treatment.

The present invention relates to a composite powder of jade powder and a porous polymer, and more specifically relates to a composite powder (jade sphere) in which jade powder particles are impregnated in a porous polymer, the composite powder being produced by spraying, in one step, a dispersion in which jade powder has been dispersed in a solution that dissolves porous polymers, and to a cosmetic composition containing the composite powder, and to a manufacturing method for the composite powder.
