A reductive composition, suitable for the dental industry, which utilizes a salt of dithionite may be provided to create an alkaline tooth whitening compound. Either Sodium or potassium dithionite may be used with marked effectiveness. A simple buffered solution of dithionite and water may whiten teeth in an alkaline environment that lessens damage to tooth ename.

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.

Oral care compositions that have hops beta acid, such as from an extract from a species in the Humulus family, and a metal ion source, such as a tin ion source and/or a zinc ion source. Oral care compositions that have a tin ion source and/or a zinc ion source and one or more hops beta acids, such as from an extract from Humulus lupulus. Oral care compositions have a tin ion source and/or a zinc ion source and a beta acid derived from an extract of Humulus lupulus.

The present disclosure relates to a nanoemulsion composition for tooth whitening and method for preparing the same, and the present disclosure provides a composition for tooth whitening and method for preparing the same, including a water phase part containing water; and an oil phase part dispersed in the water phase part and made of nanoparticle containing a perfluorocarbon compound, wherein the oil phase part includes oxygen gas. According to the present disclosure, there is an advantage of replacing peroxide and at the same time exhibit excellent tooth whitening effect.

Provided are a method for preventing or treating photoaging of skin, including: administering a composition comprising an effective amount of an extract of Agastache rugosa O Kuntze to a subject in need thereof. The composition decreases expression of matrix metalloproteinases (MMPs) induced by ultraviolet B (UVB) irradiation; decreases expression of mitogen-activated protein kinase (MAPK)/activator protein-1 (AP-1) signaling; improves collagen synthesis; decreases skin inflammation induced by NF-κB; and decreases oxidative stress induced by UVB irradiation.

A dental medicament applicator is disclosed. In one embodiment, a placement device is sized for insertion at a dental site, such as an interproximal site. The placement device includes a central body and at least one active matrix secured to the central body containing a topical substance, such as a fluoride-containing chemical agent, silver diamine fluoride, or a peptide-based chemical agent, for example. One or two wings extend from the central body to provide subterminal opposition surfaces to hold the placement device during placement. The one or more wings are free of the topical substance. The active matrix, in response to being physically affixed to the dental site, delivers the topical substance at a controlled rate to the dental site while the placement device dissolves at a quicker controlled rate.

Oil compositions containing two or more mixtures selected from the group consisting of a lauroyl glutamic acid diester mixture having a melting point higher than 33° C., a lauroyl glutamic acid diester mixture having a melting point of 20 to 32° C., and a lauroyl glutamic acid diester mixture having a melting point of −20° C. or lower can simultaneously achieve the texture properties (melting smooth feel, uniform spread over the lip surface, and transparent gloss), stability (such as improvement in breaking strength and improvement in temporal stability of the breaking strength), and the elasticity necessary for improving makeup duration of a lipstick.

The present invention provides Phosphatidylserine (PS) preparations with PS having a predetermined particle size for use in sports nutrition and/or promoting skin health in a subject. The methods of the present invention include administering a daily dose of the PS preparation to improve sports performance and/or promote skin health in a subject.

A calcium phosphate-based core-shell structured material, a method for preparing the same, and an oral care composition using the same are provided. The calcium phosphate-based core-shell structured material includes an amorphous calcium phosphate (ACP) core and a β-tricalcium phosphate (β-TCP) shell covering the core. The method includes a first sintering step and a second sintering step. The first sintering step is to sinter an ACP material at between 700° C. and 800° C. to obtain an α-TCP shell. The second sintering step allows the α-TCP shell to form into the β-TCP shell by sintering at between 800° C. and 900° C. The oral care composition includes a calcium phosphate mixture and an orally receivable carrier. The calcium phosphate mixture includes a powder of the calcium phosphate-based core-shell structured material and a tricalcium phosphate powder mixed in a weight ratio from 3:5 to 3:7.

The present disclosure provides an oral care composition including a water-miscible base component, an amorphous calcium phosphate remineralizing component including a water-soluble or partially water-soluble calcium component and a water-soluble inorganic phosphate component, and a tartar control component, wherein the oral care composition provides enamel fluoride uptake activity and tartar control activity.
