Ww. Schmidt et al., A NOVEL DIANIONIC SURFACTANT FROM THE REACTION OF C-14 ALKENYLSUCCINIC ANHYDRIDE WITH SODIUM ISETHIONATE, Journal of the American Oil Chemists' Society, 71(7), 1994, pp. 695-703
A novel derivative of alkenylsuccinic anhydride has been developed. Wh
en the anhydride is opened with sodium isethionate, a difunctional sur
factant, alkenyl carboxysulfonate (ACS), is produced. This product has
a unique combination of properties: moderate foaming, effective deter
gency, as well as the capability to function as a hydrotrope and as a
co-builder in formulated cleaning systems. This paper briefly reviews
some past studies with ACS. The utility of ACS in hard-surface cleanin
g is also examined, especially the capacity of this molecule to act bo
th as a low-streaking surfactant and a hydrotrope. This combined funct
ion should allow formulators to diminish or eliminate volatile solvent
s in a variety of cleaning products. ACS has shown merit as an agent t
o reduce soil redeposition in three different heavy-duty liquid formul
ations. Additionally, heavy-duty liquid detergents containing ACS can
be formulated to high surfactant and organic builder levels.
