Abstract: The subject matter of the present invention is a photopolymerizable liquid composition comprising at least one epoxidized polybutadiene prepolymer, at least one cationic photoinitiator, and at least one thioxanthone-derived photosensitizer, which can, for example, be in the form of a liquid dressing. The subject matter of the invention is also a process for obtaining a polymerized film from said photopolymerizable liquid composition, characterized in that said composition is applied to tissues such as the skin, the skin appendages or the mucous membranes so as to form a uniform liquid film, and the film thus obtained is subjected to ultraviolet radiation, preferably ultraviolet-visible radiation having a wavelength of between 380 and 405 nm, preferably between 385 and 395 nm.

Abstract: The present invention relates to a composition in the fluid form intended to form a dressing on the skin. This composition comprises from 6% to 12% by weight of the total weight of the composition of a cellulose derivative, from 5% to 15% by weight of the total weight of the composition of a vegetable oil, and a volatile solvent. The oil/cellulose ratio by weight is between 0.8 and 1.5. This novel dressing base makes it possible to obtain a film on the skin having satisfactory resistances to water and to rubbing actions. The film is flexible and sufficiently comfortable, in particular when the dressing is applied to a fairly extensive area of the skin.
Abstract: The present invention relates to a self-supporting interface dressing formed from a thin layer of a composition comprising a hydrophobic matrix and having through holes. According to the invention, this hydrophobic matrix comprises: per 100 parts by weight of a styrene-saturated olefin-styrene triblock copolymer having a viscosity between 0.2 and 2 Pa.s, as measured in a 10% (weight/weight) solution in toluene; from 400 to 1220 parts by weight of a plasticizer, preferably a plasticizing oil; and from 0 to 720 parts by weight of petroleum jelly; it being specified moreover that: the total amount of plasticizer and petroleum jelly is greater than or equal to 750 parts by weight; the amount of petroleum jelly is between 400 and 720 parts by weight when the amount of plasticizer is between 1000 and 1220 parts by weight.
Abstract: The present invention relates to the use of at least one compound selected among the synthetic polysulphated oligosaccharides having 1 to 4 ose units and to the salts and complexes thereof as cleaning agents for a wound. The invention can be used in particular for preparing bandages intended for cleaning wounds.
Abstract: The present invention provides a method of making a bandage from a fabric such as a knitted fabric, for example. The fabric is steamed, sprayed with a solution containing an antibacterial/antimicrobial agent in a spraying chamber 28 and then dried in a drying chamber 40.
