Abstract (en)
Novel compositions (A) contain an alkylamidopropyl betaine (I) (based on hydrogenated copra or African palm oil fatty acid), salt, water and ethanol in specific ratios to provide stable, mobile, readily pumped, clear, almost colorless solutions. Novel compositions (A) comprise mobile, readily pumped, clear, almost colorless solutions, which are stable at 5-50 degrees C, have viscosity below 100 mPa.s and contain an alkylamidopropyl betaine of formula (I), salt (S), water (W) and ethanol (E). (A) contains: (i) 52-57% (I), at least 20% (W) and at least 21% (E) (where the (I) content is calculated as dry solids content minus sodium chloride content); (ii) at least 54% (W) based on (W) plus (E) and (iii) less than 6 wt. % (S). R = residue of a hydrogenated copra or African palm oil fatty acid cut residue of iodine index 1 or less. An Independent claim is included for the preparation of (A).
Abstract (fr)
On décrit des solutions hydroalcooliques d'alkylamidopropylbétaïnes de coprah ou de palmiste hydrogéné à teneur en bétaïne supérieure à 50%, fluides, stables et pompables comme occupant une zone bien définie de leur diagramme ternaire bétaïne / eau / éthanol. On les prépare par synthèse et quaternisation de l'amidoamine directement dans le milieu solvant où elles sont définies.
