Abstract: Techniques for smoke detection are provided. In one aspect, an exemplary smoke detection device is provided. The smoke detection device comprises an infrared beam transmitting unit; an infrared beam receiving unit; and a control module associated with the infrared beam transmitting unit and the infrared beam receiving unit. The infrared beam transmitting unit and the infrared beam receiving unit are configured to communicate with each other, via an infrared beam, and with the control module, via a signal produced in response to smoke being present at a level that is greater than a threshold smoke level.

Abstract: Personal care compositions having plant fiber such as tapioca fiber, and methods of applying those formulations. The addition of fiber to personal care formulations can provide performance improvement such as cleansing, exfoliation, irritation reduction, suspending, foam enhancement, and rheological property modification.

Abstract: The present invention relates to a personal care composition comprising at least one hydroxyalkylurea in combination with at least one other moisturizing agent in a synergistically moisturizing effective ratio, which provides not only the perception of moisturization, but also actual increased moisturization efficacy. Such personal care compositions provide an enhanced smooth feel as well as enhanced flexibility, elasticity, suppleness and firmness without leaving a heavy or greasy feel.

Abstract: A personal care composition having at least one hydroxyalkylurea (HAU) optionally in combination with at least one other moisturizing agent. The at least one HAU, alone or together with the at least one moisturizing agent, provides not only the perception of moisturization, but also actual increased moisturization efficacy. When the two are used in combination in a personal care composition, they are provided in a synergistically moisturizing effective ratio to provide that perception of moisturization and increased moisturization efficacy. Such personal care compositions provide an enhanced smooth feel as well as enhanced flexibility, elasticity, suppleness and firmness without leaving a heavy or greasy feel.

Abstract: The present invention relates to the use of acrylate copolymers, which provide excellent water resistance to personal care products without the undesirable waxy, greasy or heavy feel. Further, these acrylate copolymers are easy for manufacturers to use as they can be easily incorporated into the water phase without special processing.
