A structured aqueous detergent composition comprising modified cellulose and surfactant characterised in that the composition comprises: a) 0.2 to 10 wt %, preferably 0.4 to 7 wt%, anionic surfactant or zwitterionic surfactant or mixtures thereof, b) 0.5 to 5 wt %, preferably 1 to 2 wt%, dispersed modified cellulose biopolymer, wherein the modification consists of the cellulose having its C6 primary alcohols oxidised to carboxyl moieties (acid/COOH-) on 10 to 70% of the glucose units and substantially all the remainder of the C6 positions occupied by unmodified primary alcohols, c) 0 to 10 wt % non-surfactant electrolyte; d) 0 to 15 wt% other conventional detergent composition additives e) balance water. The invention also provides a method to manufacture the composition.

Linvention concerne une composition détergente aqueuse structurée comprenant de la cellulose modifiée et un tensioactif, caractérisée en ce quelle comprend : a) 0,2 à 10% en poids, de préférence 0,4 à 7% en poids, dun tensioactif anionique ou zwittérionique ou de mélanges de ceux-ci, b) 0,5 à 5% en poids, de préférence 1 à 2% en poids                                                                                                                                                                                                                                                                                                 dun biopolymère de cellulose modifiée dispersée, la modification consistant à oxyder les alcools primaires C6 de la cellulose en fraction carbonyle (acid/COOH-) sur 10 à 70% des unités de glucose et sensiblement tout le reste des positions C6 étant occupé par des alcools primaires non modifiés, c) 0 à 10%  en poids délectrolyte non tensioactif ; d) 0 à 15% en poids dautres additifs de compositions détergentes classiques e) et le reste en eau. Linvention concerne également un procédé de production de la composition.
