DEFINITION

Classification: 508/393

Prepared by chemical reaction of existing overbased sulfonate in the absence of additional base (e.g., converting overbased sulfonate to non-newtonian or thixotropic composition; further reacting overbased sulfonate with carboxylic acid, etc.):

(under subclass 391) Compositions wherein the overbased or carbonated sulfonate is prepared by chemically reacting a previously formed overbased sulfonate, which chemical reacting takes place in the absence of any additional base.
