Abstract:
This invention relates to oral care compositions comprising an effective amount of a basic amino acid in free or salt form, together with an antibacterial agent, and to methods of using and of making such compositions.
Abstract:
This invention relates to oral care compositions comprising an effective amount of a salt of a basic amino acid, the salt having a pH in an unbuffered solution of less than about 7.5: an effective amount of a soluble fluoride salt: and a particulate material which has a pH in an unbuffered solution of less than about 7.5; and to methods of using and of making such compositions.
Abstract:
A system for detecting blood in an oral cavity during toothbrushing. The system may include a toothbrush having a sensor that is configured to emit first light at a first wavelength and second light at a second wavelength, receive reflected portions of the first and second light, and generate a first signal indicative of a first intensity of the reflected portion of the first light and a second signal indicative of a second intensity of the reflected portion of the second light. The system may include a processor operably coupled to the sensor, the processor being configured to receive the first and second signals and calculate a ratio of the first intensity to the second intensity to determine whether hemoglobin/blood is present in the oral cavity. The processor may be a part of the toothbrush or a part of a portable electronic device such as a smart phone.
Abstract:
The present disclosure is directed to a sensing agent. The sensing agent comprises a quantum dot; and a dye moiety coupled to the quantum dot. The sensing agent is capable of sensing at least one analyte chosen from hydrogen sulfide (H2S) and bisulfide. Sensors made from the sensing agents are also disclosed.
Abstract:
An anhydrous liquid antiperspirant/deodorant composition comprising a carrier comprising a cation and/or zwitterion and a hydrogen bond donor, wherein an amount of carrier is greater than an amount of any other material in the composition, and an antiperspirant active. This represents a new delivery form for antiperspirant actives and/or deodorant actives.
