Abstract:
A composition containing an alkylamidopropylbetaine corresponding to formula (I): sodium chloride, water and ethanol, in the form of fluid solutions that are easy to pump, clear, relatively colorless, stable between 5 and 50Â° C. and have a viscosity of less than 1000 mPa.s, wherein R of the alkylamidopropylbetaine represents alkyl derived from an hydrogenated coconut or palm kernel oil, said fatty acids having an iodine number at not higher than 1, wherein the betaine, water and ethanol components, given as reduced concentrations by weight are:B=[betaine/(betaine+water+ethanol)]Â·102 W=[water/(betaine+water+ethanol)]Â·102 E*=[ethanol/(betaine+water+ethanol)]Â·102 the betaine being measured as, the weight of solids minus the weight of sodium chloride, are present in the composition according to the relationships52%&lE;B*&lE;57% E*&gE;21% W*&gE;20% W*/W*+E*&lE;54% with the provision that the sodium chloride content of the composition is less than 6% by weight.
