Abstract: In one embodiment, a method includes receiving identities of features of a first composition, and receiving a value of a property of the first composition. A learning model is trained using values of predefined characteristics of the features of the first composition, and the value of the property of the first composition. The learning model is then provided identities of second features of a second composition. Using the learning model, a value of a property of the second composition is determined and displayed.

Abstract: Described herein are personal care compositions, which provide—inter alia—sweat reduction. The personal care compositions described herein may comprise humectants, thickeners, alpha hydroxy acids, and a carrier; and are typically free of added aluminum-based antiperspirant actives.

Abstract: A container, a toothbrush, or a device including at least one sacrificial electrode. In one aspect, the container may include a body adapted to contain an oral care solution and a cap selectively removable from the body. The cap may include a cavity configured to contain a fluid, a first electrode comprising a sacrificial metal, a second electrode spaced from the first electrode, and an electrical connection electrically connecting the first electrode and the second electrode to a power source. Activation of the power source may generate an electric field between the first and second electrodes, thereby causing the sacrificial metal of the first electrode to release ions into the fluid in the cavity of the cap.

Abstract: A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

Abstract: Personal care compositions are disclosed herein. In accordance with an aspect, provided is a personal care composition having a hydrocarbon having 4 to 6 carbons; a fatty ester, a fatty acid, a medium chain triglyceride, a silicone, vitamin E, or a combination of two or more thereof; and one or more surfactant, wherein the personal care composition is self-foaming.

Abstract: 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.

Abstract: A tooth sensitivity treatment device and an applicator tip thereof. The tooth sensitivity treatment device may be configured to dispense a sensitivity formulation onto a user's teeth. The tooth sensitivity treatment device may further be configured to massage the sensitivity formulation onto the user's teeth after dispensing. The applicator may have a bottom end, a top end, and a longitudinal axis extending therebetween. The applicator may include an application portion that is not intersected by the longitudinal axis. The application portion may have an outer surface that is oriented at an oblique angle relative to the longitudinal axis. The applicator may include a resilient material component and a rigid material component that are integrally coupled together. The resilient material component may form the entirety of the application portion to increase flexibility while massaging the sensitivity formulation onto the user's teeth.
