Abstract:
1. A dental floss comprising: an elastomeric matrix containing one or more particles; wherein the dental floss is adapted such that at least one of the one or more particles protrudes from the matrix in increasing amounts as increasing tensile stress is applied to the dental floss, wherein the elastomeric matrix comprises: a blend of an elastomeric block copolymer and polypropylene; and a plasticizer, and wherein at least one of said one or more particles is an abrasive particle, and the dental floss comprises from 0.1 to 5% by weight based on a weight of the dental floss, of abrasive particles, wherein the abrasive particles comprise at least one member selected from the group consisting of silica, precipitated calcium carbonate, di-calcium phosphate, mica, crystalline alumino-silicate, precipitated silica, glass beads, glass bubbles, glass microspheres, ceramic microspheres and polymers having a melting point above 200° C.; wherein the elastomeric block copolymer comprises a styrene-ethylene/butylene-styrene block copolymer and comprises 50% to 99% by weight of the blend.
