An oral care composition having a soluble zinc polyphosphate complex made by combining ingredients including a zinc salt, a plurality of long chain polyphosphates having 6 or more phosphate polymer units, and a solvent, the relative amount of organic zinc salt and long chain polyphosphates provides a phosphorus to zinc mole ratio of at least 6:1. Further provided is a method of treating a subject suffering from dentinal sensitivity applying the oral care composition to the teeth and gums of the subject.

Zinc phosphate complex

A soluble zinc polyphosphate complex made by combining ingredients which include an organic zinc salt and a plurality of long chain polyphosphates having 6 or more phosphate polymer units, the organic zinc salt and long chain polyphosphates being mixed in amounts that provide a phosphorus to zinc mole ratio of 15:1 to about 55:1. Further provided is a method of making this soluble zinc polyphosphate.

Provided are aqueous soluble tin phosphate complexes formed from a mixture comprising tin (II) fluoride or tin (II) chloride and a tripolyphosphate salt, e.g., sodium tripolyphosphate (NaPO), and oral care compositions comprising the complex and uses thereof.

Oral care compositions

A personal care composition, comprising a soluble zinc polyphosphate complex made by combining ingredients comprising an organic zinc salt, a plurality of long chain polyphosphates having 6 or more phosphate polymer units, and an aqueous solvent; wherein the relative amount of organic zinc salt and long chain polyphosphates provides a phosphorus to zinc mole ratio of at least 6:1. Also, a method of using the composition for reducing at least one of perspiration or body odor.

Personal care composition with Zinc phosphate active

The disclosure provides an improved synthesis for a zinc-lysine complex having the formula [Zn(CHNO)Cl]Cl, in which zinc chloride is reacted with lysine, in aqueous solution. The disclosure also provides oral care and personal care compositions comprising the complex prepared by the synthesis, and methods of using these complexes and compositions.

Synthesis of zinc-lysine complex from zinc chloride

Provided are aqueous soluble tin phosphate complexes formed from a mixture comprising tin (II) fluoride and a pyrophosphate salt and oral care compositions comprising the complexes and uses thereof.

Described herein, are aqueous soluble tin phosphate complexes formed from a mixture comprising tin (II) fluoride and a pyrophosphate salt. Also described are external personal care compositions comprising the complexes, and uses thereof.

Personal care compositions

Provided is a personal cleansing composition for application to the skin which comprises a zinc X halide present in an amount to provide at least 0.36 weight % of the composition of zinc, and a surfactant, wherein X is an amino acid or trimethylglycine. Methods of making and using the compositions are also provided. The zinc X halide is can be used to deliver zinc salts to reduce or prevent sunburn, kill bacteria, or reduce perspiration.

Personal cleansing compositions containing zinc amino acid/trimethylglycine halide

Described herein, are aqueous soluble tin phosphate complexes formed from a mixture comprising tin (II) fluoride or tin (II) chloride and a tripolyphosphate salt, e.g., sodium tripolyphosphate (NaPO), and external personal care compositions comprising the complexes, and uses thereof.

Provided are compositions, e.g., oral and personal care products, comprising (i) a tetrabasic zinc-amino acid or trialkyl glycine-halide complex, and (ii) cysteine in free or in orally or cosmetically acceptable salt form, together with methods of making and using the same.
