The invention relates to a new process for the manufacturing of chitin derivatives, in particular of nanofibrillary chitin, sustainable from the industrial implementation point of view and suitable to produce chitin derivatives having improved properties. The invention further relates to chitin derivatives obtainable with such method. The invention further relates to the uses of such derivatives which comprise for example the formulation of pastes and aqueous gels useful for the topic applications on skin, the manufacturing of materials of biomedical interest, as well as the deposition of chitin nanofibrils on coating surfaces or the incorporation of the same inside articles such as, for example, hygiene sanitary products.

The invention relates to compositions comprising citrus fibers and 1,3-β-D-glucans, specifically scleroglucan, for use in the manufacture emulsions or aqueous mixtures for use in topical formulations. The invention further relates to processes for manufacturing an emulsion, or aqueous mixture, or topical formulation and to uses thereof, especially in personal care products.

Methods of protecting skin of a mammal by application of silk-derived compositions useful for treating or preventing a wide variety of skin conditions. Silk solutions and silk mats are prepared and applied to the skin surface. The silk compositions may be self-adhesive or sutured to cover a wound or area of skin exposed to physical stresses and strains, thereby preventing a wound and/or promoting wound healing.

A composite particle includes a core particle having a pore and fine fibers inseparably bonded to a surface of the core particle. The fine fibers are at least either cellulose nanofibers or chitin nanofibers.

[Problem] To provide an oil thickener which has high viscosity increasing effect on an oily ingredient such as silicone oil, a non-polar organic compound, a low-polarity organic compound or the like and which has good handlability

[Means to Solve the Problem] Surface-hydrophobized cellulose nanofibers for an oil thickener which are cellulose nanofibers having an average thickness of 3 to 200 nm and an average length of 0.1 μm or larger, and a 1 wt. % aqueous dispersion of which has a viscosity of 700 to 2100 mPa.Math.s, and hydroxyl groups in cellobiose units of which are substituted by vinyl esters and/or organic acid vinyl esters in a substitution degree of 0.2 to 0.8.

An oral hygiene composition includes a mixture of: (i) a carrier liquid; and (ii) a water-insoluble hydratable polymer fibers forming an entangled three-dimensional network of said water-insoluble hydratable polymer fibers in said carrier; wherein: said carrier liquid comprises one or more humectant in a concentration of total humectant in excess of 5 wt. % based on the weight of the composition; said composition has an elastic modulus G′ and a loss modulus G″, and said elastic modulus G′ is larger that said loss modulus G″; and said water-insoluble hydratable polymer fibers have a diameter of about 10 to about 20,000 nm and a length of at least 100 nm.

A rheological solid composition comprising a crystallizing agent and an aqueous phase.

The present invention provides threads of hyaluronic acid, and/or derivatives thereof, methods of making thereof and uses thereof, for example, in aesthetic applications (e.g., dermal fillers), surgery (sutures), drug delivery, etc.

An object is to provide a skin modifying sheet as described below. According to this skin modifying sheet, a period until effects of ethyl-α-D-glucoside appear is shorter than when food products or cosmetics containing ethyl-α-D-glucoside are orally taken in or applied on the skin, and collagen in the skin can be increased at a pinpoint location. The skin modifying sheet includes a sheet-like substrate and a plurality of fine needles which is formed on one surface of the sheet-like substrate and contains ethyl-α-D-glucoside.

A rheological solid shave composition. The rheological solid shave composition has a crystallizing agent, an active and an aqueous phase.
