Abstract: The present invention relates to novel hydrocolloid adhesive masses consisting of an adhesive mixture based on a low molecular polyisobutylene and a poly(styrene/olefin/styrene) block polymer, and of a cellulose derivative, with which an acrylate polymer with a glass transition temperature below ?20° C. is associated for the purpose of increasing the resistance to deterioration of the absorption capacity of said hydrocolloid adhesive mass after radiosterilization. The invention further relates to the use of these novel hydrocolloid adhesive masses for medical, dermatological or cosmetic purposes and particularly for the production of dressings for the treatment of blisters, exudative wounds, burns and superficial, deep, chronic or acute dermo-epidermal lesions.

Abstract: The present invention relates to novel hydrophilic adhesive compositions, characterised in that they comprise a thermoplastic elastomer of poly(styrene-olefin-styrene) block copolymer type, a tackifying product, a liquid plasticizer, water and un amphiphilic copolymer. The invention also relates to the use of these novel hydrophilic adhesive compositions as adhesives for fixing any type of product, and notably products for medical, dermatological or cosmetological purposes, which come into contact with a wound, the skin or the mucous membranes.

Abstract: The present invention relates to novel solid emulsions, characterised in that they comprise a thermoplastic elastomer of poly(styrene-olefin-styrene) block copolymer type, an aqueous phase, an oily phase and an amphiphilic copolymer. The invention also relates to the use of these novel solid emulsions notably for the preparation of products for medical, dermatological or cosmetological purposes which come into contact with a wound, skin or mucous membranes.

Abstract: The compress is of the type including a contact surface with the wound or burn which has an elastomeric matrix highly plasticized with a non-polar oil or grease, the elastomeric matrix containing a hydrocolloid in dispersion. The elastomeric matrix also contains, in dispersion, at least one antiseptic and at least one surfactant with a hydrophilic/lipophilic balance (HLB) greater than 10. The invention is applicable particularly to compresses and dressings.

Abstract: The invention concerns novel copolymers of the poly(styrene)-poly(ethylene-butylene)-poly(styrene) type wherein the central poly(ethylene-butylene) sequence has been modified by chemical grafting of hydrophilic groups to make them amphiphilic. The invention also concerns a method for preparing said novel amphiphilic copolymers and their use in particular as emulsifying agent or absorbent.

Abstract: The present invention relates in general terms to novel adhesive elements capable of being stacked without protection, and to the process for their manufacture.

Abstract: The present invention relates to a novel hydrocolloid adhesive mass useful for medical purposes, characterized in that said hydrocolloid adhesive mass comprises: a) 0.2 to 5 parts by weight of an ethoxylated sorbitan fatty acid ester; b) 20 to 50 parts by weight of a hydrocolloid; c) 32 to 120 to parts by weight of an adhesive matrix made up of one or more polymers selected from poly(styrene/olefin/styrene) block copolymers, low-molecular polyisobutylenes and high-molecular polyisobutylenes, and one or more compounds selected from sticky resins, or tackifying resins, plasticizers, polybutenes, antioxidants, ethylene/vinyl acetate copolymers, butyl rubbers and ethylene/propylene block copolymers; and d) 0 to 15 parts by weight of an acrylate copolymer with a glass transition temperature below −20° C.

Abstract: It is characterized in that at least one cohesive and elastic pressure-sensitive adhesive patch which can be repositioned on the skin is used, and said patch can be detached from the prosthesis by pulling parallel to the surface of the prosthesis.

Abstract: The present invention relates to a composite of the printing-writing medium/adhesive type, in which the said printing-writing medium consists of a polyolefin in sheet form and is provided on one of its sides with the said adhesive, the said composite being characterized in that it consists of:(A) a printing-writing medium in the form of a microporous sheet of polyolefin of high molecular weight, and(B) a pressure-sensitive adhesive without a plasticizer and containing(1) 90 to 160 parts by weight of a rosin resin having an average molecular weight (AMW) of between 600 and 1500 and a softening point above 85.degree. C., per(2) 100 parts by weight of an elastomer polymer material consisting of or containing at least one polyisoprene compound.This composite is especially useful for producing labels intended for the identification of blood bags made of SEBS or EVA.

Abstract: The invention concerns a novel hydrophile adhesive mass to be used for medical purposes characterised in that said hydrophile adhesive mass comprises:(a) 10 to 35 parts by weight of sequenced poly(styrene/olefin/styrene) copolymer, in particular poly(styrene/isoprene/styrene),(b) 20 to 50 parts by weight of a tackifier resin,(c) 2 to 15 parts by weight of an acrylate polymer with a glass temperature less than -20.degree. C.,(d) 2 to 25 parts by weight of a plasticizer, in particular a plasticizing oil,(e) 20 to 50 parts by weight of a hydrocolloid,(f) 0.1 to 2 parts by weight of at least one antioxidant.The invention also concerns the use of this adhesive mass for making protective bandages, in particular for treating blisters, skin-deep dermo-epidermic lesions, exudative wounds and burns.
