摘要:
An ultrasonic mixing system having a treatment chamber in which antimicrobial agents, particularly, hydrophobic antimicrobial agents, can be mixed with one or more formulations is disclosed. Specifically, the treatment chamber has an elongate housing through which a formulation and antimicrobial agents flow longitudinally from a first inlet port and a second inlet port to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the formulation and antimicrobial agents within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the formulation and antimicrobial agents being mixed in the chamber.

An ultrasonic treatment system having a treatment chamber for treating a formulation to increase the shelf life thereof. In one embodiment, the shelf life is produced by degassing the formulation using the treatment chamber. Specifically, the treatment chamber has an elongate housing through which a formulation flows longitudinally from an inlet port to a first outlet port and a second outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the formulation within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the formulation being treated in the chamber.

A cooling composition for application to the skin of a mammal, such as a human. The base of the composition is an interpenetrating polymer network, which may contain a thermo-responsive polymer. Having a Critical Temperature above an average core body temperature, the material may undergo a phase change as the creature becomes too warm, such as when a person experiences a hot flash, a fever, exposure to very warm environments, physical exertion, and the like. The phase change results in a cooling and/or cooling sensation of the skin. Additives may be included in the cooling composition such as evaporative cooling components, neurosensory cooling components, and additional phase change components.

The present disclosure is directed to a system and methods for maintaining or improving hand health and hygiene. More particularly, the system and methods prevent or overcome skin damage caused by frequent hand washing and use of hand sanitizers and/or cleansers. The hand care system comprises an article, such as an elastomeric glove, that has a moisturizing liquid liner composition on the skin-contacting surface of the article that delivers a skin health benefit to the skin, a non-irritating hand cleanser capable of moisturizing the skin, and a moisturizing hand sanitizer.
摘要:
Delivery compositions and substrates for imparting a volatile active agent to a surface are disclosed herein. To achieve the delivery of the volatile component, a delivery composition of a carbohydrate matrix and a volatile component is incorporated into the carbohydrate matrix to stabilize the volatile for extended periods of time. The delivery composition further comprises a self-generating expelling agent to expel the volatile component onto the contaminated surface or skin upon addition of a triggering agent.

An ultrasonic mixing system having a treatment chamber in which at least two separate phases can be mixed to prepare an emulsion is disclosed. Specifically, at least one phase is a dispersed phase and one phase in a continuous phase. The treatment chamber has an elongate housing through which the phases flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the phases within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the phases being mixed in the chamber.
