Hair treatment preparations |
摘要 |
Aqueous hair treatment preparations containing as anionic surfactant an alkylether sulfonate corresponding to the following formula R1-O-(CnH2nO)x-(CH2)y-SO3(-)M(+) in which R1 is a C8-C18 alkyl group, n=2 or 3, x=0 to 20, y=1 to 3 and M(+) is an alkali metal ion. Alkylether sulfonates such as these show high foaming power, are easy to thicken and are stable to hydrolysis in acidic medium. They can be prepared by reaction of corresponding alkylether sulfates with sodium sulfite in aqueous solution and extraction from the reaction mixture with a saturated C4-C6 alcohol.
