Abstract:
Compositions containing an alkylamidopropylbetaine, salt, water and ethanol, in the form of fluid solutions that are easy to pump, clear, relatively colourless, stable between 5 and 50Â° C. and have a viscosity of less than 1000 mPa.s, the alkyl radical of the said alkylamidopropylbetaine being that of a natural fraction of fatty acid of coconut or palm oil type, characterized in that the betaine, water and ethanol components, given as reduced compositions byB*=[betaine/(betaine+water+ethanol)]Â·102 W*=[water/(betaine+water+ethanol)]Â·102 E*=[ethanol/(betaine+water+ethanol)]Â·102 where betaine has the sense of, and is measured as, betaine=solidsâˆ’NaCl,are linked by the relationships55%&lE;B*&lE;62% E*&gE;21% 37%&lE;W*/W*+E*&lE;50% which define their field of existence of the compositions as long as their salt content is less than 4.5% by weight.
