摘要 |
<p>This invention discloses a method of producing directly esterified fatty acyl isethionate having a yellowness index less than about 6.0, which consists essentially of reacting a fatty acid with an alkali metal isethionate in the presence of a catalyst comprising a mixture of ZnO and an organic sulfonic acid wherein the molar ratio of ZnO to organic solfonic acid is about 1:1.7 or less and heating at about 200 DEG C. to about 255 DEG C. for sufficient time to produce the desired directly esterified fatty acyl isethionate.</p> |
