Abstract: Disclosed is a high yield process for preparing di-substituted imidazoline fabric conditioning compounds. In this process, an acylating agent such as fatty acid is reacted with a specific polyamine, and the product of this reaction is thereafter reacted with either a fatty acid ester or glyceride under specifically-defined conditions and in the presence of an esterifying catalyst such as titanium alkoxide. Use of particular reaction conditions and an esterification catalyst significantly increases the yield of di-substituted imidazoline compounds.

Abstract: 2,2'-oxodisuccinate detergent builder salts (ODS), especially tetrasodium 2,2'-oxodisuccinate, are difficult to dry and tend to pick up water due to the hygroscopicity of the 2,2'-oxodisuccinate: yet the present invention secures improved granular built detergent compositions comprising ODS by an aqueous ODS/zeolite coagglomeration process, the resulting agglomerate being remarkably stable and nonhygroscopic. Other detergent ingredients, such as perborate bleach, surfactants and the like, can be dry-mixed with the agglomerates to form fully-formulated granular detergents. The invention encompasses the agglomeration process, the ODS agglomerates and granular detergent compositions containing same.
Abstract: The present invention relates to compositions and methods for inhibiting plaque. In particular, this invention relates to oral compositions comprising: (a) a safe and effective amount of a carboxy-substituted polymer active agent having the formula ##STR1## or the salts thereof, wherein R is a C.sub.1 -C.sub.8 alkyl group, n is in the range of from 0 to about 2,000, m is in the range of from about 10 to about 2,000, and p is in the range of from about 1 to about 10; and (b) a pharmaceutically acceptable carrier. These compositions inhibit plaque without staining the tooth surfaces which are contacted with the composition.This invention also relates to a method of inhibiting plaque on tooth surfaces in the oral cavity. This method involves applying a safe and effective amount of the carboxy-substituted polymer active agent to the oral cavity. Such an application is typically made by applying the above-described oral compositions containing the carboxy-substituted polymer to the tooth surface.
