The present disclosure relates to fragrance materials encapsulated within polymeric materials in the form of microcapsules of polymer encapsulated fragrance. The microcapsules are mixed with a water-based binding agent so that a coating forms on the microcapsule in situ, after which the coated microcapsules may be applied to hard surfaces of a product, from which controlled release of the fragrance is provided over time as the product is subjected to normal handling by a user.

The method of producing an ultraviolet protective agent composition includes at least step (a) of precipitating iron oxide microparticles by mixing with a microreactor an iron oxide raw material fluid containing at least Fe.sup.3+ ion, and an iron oxide precipitation fluid containing at least a basic substance; and step (b) of dispersing the above precipitated iron oxide microparticles in a dispersion medium to obtain iron oxide microparticle dispersion, wherein a haze value of the iron oxide microparticle dispersion is 2.0% or less, and a transmittance of the iron oxide microparticle dispersion for the light of the wavelengths of 200 to 420 nm is 2.0% or less.

Nano-node sunscreen described herein enables significantly improved health monitoring and treatment of sun-related issues by utilizing internal (in-body) mechanisms and information and external mechanisms and information.

The present invention discloses a unidirectional moisturizing nanofiber facial mask substrate with asymmetric wettability and preparation thereof. The preparation includes: preparing a superhydrophilic electrospun fiber membrane on a substrate by electrospinning; preparing a hydrophobic electrospun fiber membrane by electrospinning on a lateral surface of the superhydrophilic electrospun fiber membrane away from the substrate to form a double-layered membrane; and removing the substrate, and drying the double-layered membrane to obtain the asymmetric unidirectional moisturizing facial mask substrate with one side being superhydrophilic and the other side being hydrophobic. The superhydrophilic layer can absorb a nutrient solution and be applied to the skin surface, while the hydrophobic layer can keep itself dry, reduce the consumption of the nutrient solution and inhibit volatilization of the nutrient solution. The process is simple, uses readily available materials, and is non-toxic, environmentally friendly, and low-cost, thus solving several key problems with current commercial facial mask substrates.

A layered solid formulation as one hydrogen supply material according to the present invention includes silicon fine particles having a capability of generating hydrogen and aggregates of the silicon fine particles, and a physiologically acceptable medium that gets contact with the silicon fine particles or the aggregates thereof. The hydrogen supply material is a hydrogen supply material for bringing the hydrogen into contact with the skin and/or the mucous membrane through the medium.

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 physical/inorganic sunscreen 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 to provide an enhanced SPF value for the sunscreen formulation that is at least 1.5 times the first SPF value generated by the physical/inorganic sunscreen active ingredient when the physical/inorganic sunscreen active ingredient is present at a same amount in a formulation that does not contain gadusol.

Embodiments relate to a composition comprising nanohydroxyapatite (NHAP) in an amount about 0.5 wt. % to about 50 wt. % of the composition having a particle size in a range of about 20-100 nm, an abrasive, a sweetener, and a natural oil, wherein the composition does not contain glycerin and fluoride, wherein the composition is alkaline and a dental product, and wherein the natural oil is a plant product.
