ABSTRACT OF THE DISCLOSURE: An antistatic and fabric softening laundry wash cycle additive article includes an antistatic and fabric softening composition in a filtering container, from which a complex of cationic surfactant and anionic surfactant is released into the wash water through the filtering walls of the container. The particles of the released complex, the size of which are controlled by the sizes of the filtering openings in the container walls, are small enough so that they do not form objectionable greasy deposits on the laundry, such as often results when antistatic and fabric softening cationic surfactant is present with anionic surfactant in a detergent composition, or is added to the wash water with such detergent composition. the cationic surfactant may be present in the filtering container as a complex with anionic surfactant or in mixture with anionic surfactant, in particulate form. It is preferred that it be present as such a mixture and also present may be suitable functional and aesthetic materials, such as ben- tonite, builders and fillers, which add bulk to the product and separate their active anionic and cationic material during storage; emulsifiers, which facilitate the production of cationic/anionic complex in finely divided emulsified form after the article is added to the wash water, thereby facilitating passage of such complex in such finely divided, emulsified form through the filtering container, and prevent- ing greasy deposition of such complex on the laundry being washed; and perfume.
