There is provided a surface-active material that comprises fibres which have been modified so as to impart surface-active properties onto said fibres and giving it a contact angle between 60~ and 120~, wherein the fibres have an aspect ratio of more than 10 to 1,000. The surface-active material can be used for foam and emulsion formation and stabilisation, coatings, encapsulation and drug delivery. It can for example be used in the following industries: foods, home and personal care, oilfield, agriculture, textile, construction, emulsion polymerisation, leather, plastic, pulp, paper and pharma.
L~invention concerne un matériau tensioactif comprenant des fibres, lesdites fibres ayant été modifiées de manière à présenter des propriétés tensioactives et un angle de contact compris entre 60° et 120°, lesdites fibres ayant un rapport longueur/diamètre compris entre plus de 10 et 1 000. Ce matériau tensioactif peut être utilisé pour la formation et la stabilisation d~émulsions et de mousses, pour des revêtements, des encapsulations et la délivrance de médicaments. Il peut par exemple être utilisé dans les domaines suivants : alimentaire, hygiène personnelle et produits pour la maison, champs pétroliers, agriculture, textile, construction, polymérisation en émulsion, cuir, plastique, pâte, papier et pharmaceutique.
