Abstract: Aspects of the invention are directed to oral care compositions. In accordance with an aspect, provided is an oral care composition having a surfactant system comprising at least one of: (i) a non-sulfate based anionic surfactant and an amphoteric surfactant, or (ii) a nonionic surfactant and an amino acid surfactant; a stannous ion source; a nitrate ion source; and a phosphate source.

Abstract: Described herein are oral care compositions having a surfactant system comprising four or more surfactants individually selected from a non-sulfate based anionic surfactant, an amphoteric surfactant, a nonionic surfactant, and an amino acid surfactant; a stannous ion source; a nitrate ion source; and a phosphate source. Methods of making and using these compositions are also described.

Abstract: A terrying mechanism for mounting on that one of the two cylinders (2) of a double-cylinder knitting machine, through which fabric is not removed from take-down. The mechanism includes a pillar (22) adapted for journalling at one end on a part (14) at the base of the cylinder (2) rotating jointly therewith and carrying at the other end an annular cam system (20) with a retractable cam means (55) for coacting with terrying instruments (90, 91, 94) carried in generally radially extending tricks (60) in a dial (62) having a journalling means (68) in axial alignment of the pillar (22).
