Abstract
Abstract Abstract: Methods of simultaneously washing, softening, and controlling static electricity in an automatic washer are disclosed. In accordance with these methods a composition of this invention is added to an automatic washer along with a conventional detergent and the fabrics to be laundered, each of which is added at the initiation of the wash cycle. The compositions disclosed contain a primary secondary or tertiary amine or a salt thereof. These compositions are either in a granular form, which contains an adjuvant and a particulate amine having a particle size of less than 420 microns, or in a liquid form, which is aqueous based with a pH of less than 7 and contains an acid and a salt of one of the amine compounds.

Claim 1
Independent Claim
211 words
The process of softening fabrics in an automatic washer during the wash cycle of the automatic washer which comprises the steps of: (a) adding a premeasured amount of a conven-tional laundry detergent and fabrics to be laundered to the washer; (b) activating the washer so that the tub of the washer fills with water; (c) adding an effective amount of: (i) a granular material containing a mixture of an adjuvant and a particulate nitrogen containing compound having a particle size of less than 420 microns and said nitrogen containing compound being selected from the group consisting of primary amines, secondary amines, tertiary amines, and the acetate, sulfate or hydrochloride salts thereof, wherein said amines and their salts have at least one straight chain organic radical of between 8 and 22 carbon atoms and wherein the ratio of adjuvant to nitrogen containing compound is from about 15:1 to about 2:1; or (ii) an aqueous based composition having a pH of less than 7 and containing a nitrogen containing compound selected from the group consisting of the acetate, sulfate, and hydrochloride salts of primary, secondary, or tertiary, amines having at least one straight chain organic radical of between 8 and 22 carbon atoms; and (d) operating the washer through all of its cycles.
