The present application also provides a medical product for covering tissue comprising a bioactive molecule covalently bound to nanofibrillar cellulose.

An oil-in-water emulsion cosmetic material containing the following component (A) to (C): Component (A): a hydrophobized fine-particulate metal oxide having an average primary particle diameter of less than 100 nm, Component (B): an aqueous phase thickener containing a structure derived from 2-acrylamido-2-methylpropanesulfonic acid, Component (C): an amphoteric surfactant, wherein the content of the component (A) is 7% by mass or more and 30% by mass or less.

Embodiments of sunscreen formulations are disclosed herein. In one example, a sunscreen formulation includes a) a physical/inorganic sunscreen active ingredient at from about 5% to about 25% on a weight/weight (w/w) basis, wherein the active ingredient generates a first sun protection factor (“SPF”) value to a sunscreen formulation; b) gadusol; and c) a plurality of ingredients configured to deliver ingredients a) and b) in the sunscreen formulation, wherein the gadusol is present in the sunscreen formulation in an amount sufficient to generate a SPF booster effect in the sunscreen formulation.

The present invention provides a nanocomposite material comprising a palmitoyl tetrapeptide-20 conjugated nanosilver particle. The nanocomposite material of the present invention has good stability and does not easily deteriorate, and it also exhibits the effects of excellent cutaneous penetration ability, reduced free radical damages, and promotion in melanin synthesis in hair, thereby restoring original hair color and thus solving the problems of premature or mid-aged hair graying.

Provided herein are magnetically-responsive, photosensitizer based antimicrobial microemulsions and photodynamic nanoplatforms in which a photosensitizer functionally associated with a plurality of superparamagnetic iron oxide nanoparticles are encapsulated. Also provided are methods and processes utilizing the antimicrobial microemulsions and photodynamic nanoplatforms to treat an oral disease, to reduce a microbial population in a pathogenic oral biofilm and to improve the efficacy of a photosensitizer during an antimicrobial photodynamic therapy treatment of an oral disease.

A composition for reducing microbial activity in an environment susceptible to microbial activity, comprising: metallic nanoparticles; and an oxygenation agent.

Provided are: a core-corona polymer particle excellent in emulsion stability and feeling of use, and a raw material for a cosmetic and an oil-in-water emulsion cosmetic comprising the particle. Certain embodiments of the present invention provides a core-corona polymer particle obtained by radical-polymerizing a polyethylene oxide macromonomer represented by formula (1) and one or two or more of hydrophobic monomers represented by formulas (2) and (3) under conditions (A) to (D).

A container configured to hold a multiphase shampoo composition. The multiphase shampoo composition has a cleansing phase containing a detersive surfactant and a benefit phase containing a gel network. The cleansing phase and benefit phase are visually discrete phases, in physical contact, and form an aesthetic design suspended across at least a portion of the container.

The present invention relates to a cosmetic skin lightening composition comprising the combination of sclareolide, kojic acid and ascorbyl glucoside, wherein kojic acid is encapsulated within a targeted microcapsule or nanocapsule having a melanocortin 1 receptor (MC1R) agonist peptide bound to the surface. It was found that such combination of active substances provided synergistic kin-whitening effect. The present invention also relates to the cosmetic use of this composition for skin whitening, particularly, for the elimination or reduction of hyperpigmented marks of the skin, such as UV exposure related marks, post-scar marks, post-inflammation marks, melasma marks, lentigo marks or age-related marks.

Calcium and silicon are known to strengthen the formation of hair, skin and nails. The efficacy of oral intake of calcium and silicon is very difficult. Local delivery and uptake of the ions would enable more efficient strengthening of 5 nails, skin or hair. The invention relates to the addition of calcium silicate to products for local release of calcium and silicate to nails, hair and skin.
