Abstract: The present invention relates to core shell silica particles, wherein each core shell silica particle comprises a silica core, and a surface of the silica core is etched with metal silicate, the core shell silica particles prepared by: i) admixing an amount of silica particles in water with an amount of a base, wherein the base comprises a monovalent metal ion, to produce core shell silica particles, each core shell silica particle comprising a silica core, and a surface of the silica core etched with a silicate of the monovalent metal ion; and ii) reacting the core shell silica particles formed in step i) with a metal salt comprising a second metal ion, to form core shell silica particles comprising silicate of the second metal ion on the surface of the silica core.
Abstract: A tracking attachment for an oral care implement that includes a housing and a tracking unit configured to track position, orientation, or movement of the oral care implement. The housing may define a receiving cavity that is configured to receive a portion of the oral care implement. The housing may include a first housing portion having an inner surface that defines a first portion of the receiving cavity that is open at both of the first and second ends of the first housing portion and a second housing portion that mates with the first housing portion to detachably couple the second housing portion to the first housing portion. The second housing portion may have an inner surface that defines a second portion of the receiving cavity that is open at the second end of the second housing portion.
Abstract: Disclosed herein are skin care compositions, comprising vitamin E (e.g., alpha-tocopherol), a thiourea derivative of histidine (e.g., ergothioneine), a vitamin B3 compound (e.g., niacinamide) and/or a pyrrolidone carboxylic acid and/or a salt thereof (e.g., sodium PCA) as well as to methods of using these compositions.

Abstract: The present disclosure relates to oral care compositions comprising amino acids and a cannabinoid. Methods of making and use are further provided.
Abstract: This invention relates to oral care compositions comprising a cannabinoid, and one more source(s) of zinc ions and/or stannous ions. The oral care composition may also comprise one or more stannous source(s). Methods of using and of making these compositions is also disclosed herein.
Abstract: An intraoral device (100) for determining oral health characteristics is provided. The device includes a light source (106) configured to emit light in a plurality of wavelengths within or about the oral cavity and a matrix array multispectral sensor (102) configured to detect a plurality of spectral channels of a spectral image. Each of the plurality of spectral channels may allow transmission of a corresponding wavelength. The device may include a processor (1100) configured to identify the detected plurality of spectral channels of the spectral image relating to the oral cavity. Based on the detected plurality of spectral channels, the processor may cause the light source to adjust the light emitted within or about the oral cavity to modify a signal to noise ratio and/or an image calibration of a subsequent spectral image. The matrix array multispectral sensor may capture the subsequent spectral image relating the oral cavity in the adjusted emitted light.

Abstract: An oral care implement body to which a replacement head can be detachably coupled. In one embodiment, the oral care implement body includes a gripping portion having a shoulder, a stem extending from the shoulder along a longitudinal axis, and a boss protruding from an outer surface of the stem. The boss may have a locking rib section having an undercut surface that is axially spaced from the shoulder and a positioning rib section extending from the locking rib section to the shoulder. The undercut surface may circumferentially protrude from a first side surface of the positioning rib section. The locking rib section may extend along a first rib axis and the positioning rib section may extend along a second rib axis, the first rib axis oriented obliquely to the second rib axis.
Abstract: A toothbrush includes a handle, a head at a distal end of the handle comprising a bristle plate, a hole extending through the bristle plate, a plurality of bristles at least partially disposed in the hole and extending from the hole in a direction away from the head, and a reservoir in fluid communication with the hole. Fluid in the reservoir enters the tuft holes and is wicked out of the head of the toothbrushes by capillaries formed between the bristles.
