Abstract: Fabric conditioning compositions are disclosed which comprise, as a fabric softening ingredient, a fabric softening clay. The fabric softening clay is a hectorite of natural origin, and has a layer change distribution such that at least 50% is in the range 0.23-0.31. The clays exhibit high relative deposition values.

Abstract: Disclosed is a high yield process for preparing substituted imidazoline fabric conditioning compounds. In this process, a fatty acylating agent, e.g., fatty acid, is reacted with a specific polyamine, and the product of this reaction is reacted with an esterifying agent, both reactions being conducted under specifically-defined conditions. Aqueous dispersions containing these substituted imidazoline compounds possess desirable storage stability, viscosity, and fabric conditioning properties.
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 plaque-inhibiting carboxy starch polymer comprising the formula ##STR1## wherein W and X are independently selected from CH.sub.2 OH, CHO and CO.sub.2 H, or the neutralized carboxylic acid salts thereof, Y and Z are independently selected from CHO and CO.sub.2 H, or the neutralized carboxylic acid salts thereof, n is in the range of from about 5 to about 2500, m is in the range of from 0 to about 2500, provided that the sum of n and m ranges from about 5 to about 2500, and the degree of carboxylation of said active agent ranges from about 1 to about 3; and (b) a pharmaceutically acceptable carrier. These compositions inhibit plaque without staining the teeth which are contacted with the composition.This invention also relates to a method of inhibiting plaque on tooth surfaces in the oral cavity.

Abstract: Nutritional mineral supplements comprise iron compounds and calcium compounds in combination with citrates or tartrates, ascorbates, and, optionally, fructose. The tendency of calcium to inhibit the bioavailability of iron is reduced in such compositions, so that conjoint bioavailability of these two important minerals is enhanced.
