摘要： A whitening dentifrice composition includes a blue coloring agent, a zinc salt, and an orally acceptable vehicle. The blue coloring agent is selected from the group consisting of a blue pigment and a blue dye. The blue pigment has a blue to blue-violet color with a hue angle in the CIELAB system ranging from 200 degrees to 320 degrees. The whitening dentifrice composition provides a greater whitening benefit to a tooth surface in comparison to a dentifrice composition that does not contain the zinc salt.

摘要： A bristle for an oral care implement and an oral care implement including a plurality of such bristles. The bristle may include a body extending along a longitudinal axis from a proximal end to a distal end, the body having tapered portion having a transverse cross-sectional profile with a perimeter defined by a first linear section and a second linear section that intersect to form a first apex, a third linear section and a fourth linear section that intersect to form a second apex, a first curved section extending between the first and third linear sections, and a second curved section extending between the second and fourth linear sections. The body may also include a cylindrical body portion such that the tapered portion extends from a top end of the cylindrical body portion. The bristle includes various edges and rounded contours for enhanced cleaning.

摘要： In one embodiment, a personal care appliance includes an electric motor having a drive shaft. In response to a voltage signal, the drive shaft is oscillated in an oscillatory motion having an oscillation amplitude. A control circuit includes, in operable cooperation, a user interface, a processor, a pulse width modulation signal generator, and a power source. The control circuit supplies the voltage signal to the electric motor, the voltage signal having a frequency and a duty cycle. The control circuit varies the frequency and the duty cycle of the voltage signal in response to an oscillation adjustment input received from the user interface so that the oscillation amplitude of the drive shaft is varied along a substantially linear rate of change profile relative to the frequency.

摘要： A system, apparatus, and/or method is disclosed for producing a personal care product. An identity of a considered chemical composition may be input into a model (e.g., a machine learning model). The identity of the considered chemical composition may include ingredients. Each of the ingredients of the considered chemical composition may be associated with a value of a chemoinformatic property of chemoinformatic properties of the considered chemical composition. A value of the property of the considered chemical composition may be determined via the model. The value may be based on the identity of the considered chemical composition. The property of the considered chemical composition may be affected by an interaction of at least two of the ingredients of the considered chemical composition. A personal care product comprised of the considered chemical composition may be produced.

摘要： A method of priming an applicator of a personal care implement with a fluid. The method may include flowing a fluid along a first capillary member from a reservoir of a fluid supply system to an applicator of a personal care implement along a first fluid flow path, and flowing the fluid along a second capillary member from the reservoir of the fluid supply system to the applicator of the personal care implement along a second fluid flow path that is distinct from the first flow path. In one aspect, the fluid flowing along the second fluid flow path reaches the applicator before the fluid flowing along the first fluid flow path. In another aspect, the first capillary member is formed of a non-absorbent material and the second capillary member is formed of an absorbent material.

摘要： An oral care implement is described. The oral care implement may include a head extending along a longitudinal axis and having a first surface, a second surface opposite the first surface, and a side surface extending between the first surface and the second surface. A central bristle tuft may from a central portion of the first surface. A plurality of perimetric bristle tufts may from the first surface and arranged to circumferentially surround the central bristle tuft. The perimetric bristle tufts may have distal ends that slope downwardly towards the central bristle tuft. The perimetric bristle tufts may be wedge shaped.

摘要： An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a first component comprising a first housing having an inner surface that defines a first cavity and a second component comprising a second housing having an inner surface that defines a second cavity. When the tracking attachment is coupled to the oral care implement, a first portion of the handle is positioned within the first cavity and a second portion of the handle is positioned within the second cavity.

摘要： An oral care implement having tooth cleaning elements and an elastomeric soft tissue cleanser. In one aspect, the oral care implement has a handle and a head coupled to the handle, an elastomeric soft tissue cleanser having a plurality of protuberances extending from a rear surface of the head, and a plurality of tooth cleaning elements extending from a front surface of the head. The protuberances of the elastomeric soft tissue cleanser collectively define a convex longitudinal side profile and comprise at least one convex transverse top profile. The plurality of tooth cleaning elements collectively define a concave longitudinal side profile and comprise at least one concave transverse top profile.
