Claim 1
Independent Claim
137 words
A detergent composition in particulate form having fabric conditioning properties, consisting essentially of: a. from about 2% to about 99.5% by weight of an organic surface-active agent selected from the group consisting of anionic, nonionic, zwitterionic and ampholytic detergents and mixtures thereof; and b. from about 0.05% to about 10% by weight of a substantially water-insoluble particulate material having: i. an average particle size in the range from about 5 to about 30 micrometers; ii. a shape having an anisotropy of about 5:1 to 1:1; iii. a hardness of less than about 5.5 on the Moh scale; iv. a melting point above about 150° C; and v. substantial freedom from exchangeable calcium and magnesium ions, said water-insoluble particulate material being selected from the group consisting of glass beads, glass beads, glass microballoons, ceramic beads, and mixtures thereof.
