Beschreibung
Zusammenfassung:	The present application provides a water-soluble, partially biodegradable dihydroxyalkyl cellulose having about 0.7 to about 2.0 units of dihydroxyalkyl moiety per anhydroglucose moiety, having (i) a molecular weight of dihydroxyalkyl cellulose is in the range of from about 10,000 Daltons to about 1,500,000 Daltons, (ii) a biodegradation rate of ≥ 3% in an aquatic medium, and (iii) a water solubility at a threshold level of 2g/L. Also discloses a method for preparing dihydroxyalkyl cellulose and functionalized dihydroxyalkyl cellulose compounds and their use in personal care applications. La présente invention concerne une dihydroxyalkyl cellulose soluble dans l'eau, partiellement biodégradable ayant environ 0,7 à environ 2,0 unités de fraction dihydroxyalkyle par fraction anhydroglucose, ayant (i) un poids moléculaire de dihydroxyalkyl cellulose se situant dans la plage d'environ 10 000 Daltons à environ 1 500 000 Daltons, (ii) un taux de biodégradation ≥ 3 % dans un milieu aquatique, et (iii) une solubilité dans l'eau à un niveau seuil de 2g/L. L'invention concerne également un procédé de préparation de dihydroxyalkyl cellulose et de composés de dihydroxyalkyl cellulose fonctionnalisés et leur utilisation dans des applications de soins personnels.
