Described herein is a nanofibre matrix comprising 100% natural biopolymers selected from polysaccharides and/or proteins with optional functional ingredients for use as cosmetic products. More specifically, nanofibre matrix manufactured by electrospinning methods comprising a dry sheet without containing any preservatives, surfactants, solvents and crosslinkers. To use nanofibre cosmetic products, simply wet skin and then apply the nanofibre to skin. Functional ingredients may be optionally incorporated within the nanofibre matrix during electrospinning to provide different cosmetic effects. Functional ingredients offer skin benefits such as moisturizing, anti-ageing, wrinkle reduction, brightening, antioxidant and acne treatment. Functional ingredients can be essential oil where it is incorporated into nanofibre matrix to provide scent effect to cosmetic products. Functional ingredients can also be natural dye where it is incorporated in nanofibre matrix to make coloured nanofibres. Coloured nanofibres can be used for makeup products such as blush, eye shadow, eyebrow, nail polish, lipstick, contouring and hair dye product. The nanofibre matrix comprising 100% natural biopolymers with or without functional ingredients can be processed to assorted shapes or easily cut by consumers for using on different areas of skin for different purposes.

The coating formation method of the present invention is a method for forming a coating on a surface of a coating formation target. The formation method of the present invention includes an electrostatic spraying step of electrostatically spraying a composition directly onto the coating formation target, thereby forming a coating composed of a deposit containing fibers. The composition contains a component (a), a component (b), and a component (c) below. (a) One or more volatile substances selected from water, alcohols, and ketones. (b) A polymer having coating formability. (c) A liquid agent containing one or more selected from oils and polyols that are in a liquid form at 20° C.

A nanofiber sheet has a nanofiber layer composed of an accumulation of nanofibers. The nanofiber sheet has a plurality of membrane-like regions which extend between the nanofibers. The membrane-like regions of the nanofiber sheet each contain a water insoluble polymer and a pigment. The water insoluble polymer contained in the membrane-like regions of the nanofiber sheet is different from a constituent member of the nanofibers. The nanofiber sheet is preferred because it has a plurality of membrane-like aggregate regions, each an aggregate of a plurality of membrane-like regions which are adjacent to each other via a fiber and it has a non-membrane-like region between the membrane-like aggregate regions adjacent to each other.

The present invention relates to methods and compositions for the delivery of cosmetics and medicants. In some embodiments, the invention relates to compositions comprising both hydrophobic and hydrophilic polymers. In preferred embodiments, the invention relates to the delivery of peptides, small molecules and other bioactive compounds using the compositions and methods disclosed herein.

[Object] The present invention provides a sulfonated fine cellulose fiber having excellent viscosity and the like, as well as a sulfonated fine cellulose fiber production method capable of efficiently producing the sulfonated fine cellulose fibers.

[Method for Achieving the Object] A fine cellulose fiber obtained by fibrillating a cellulose fiber wherein a part of the hydroxyl groups of the fine cellulose fiber is substituted with sulfo groups, and an introduction amount of sulfur attributable to the sulfo groups is higher than 0.42 mmol/g. The fine cellulose fiber comprises a plurality of unit fibers and has an average fiber width of 30 nm or less. A dispersion liquid in which the fine cellulose fiber is dispersed in a water-soluble solvent at a solid concentration of 0.5% by mass has a viscosity of 5,000 mPa.Math.s or more at 25° C. This makes it possible to obtain the desired viscosity when the fine cellulose fibers are dispersed in a dispersion liquid.
