Abstract: Methods, systems, and devices for activity goal personalization are described. A user device may receive physiological data associated with a user from a wearable device. The user device may compute a recovery metric for the user based at least in part on the received physiological data. The user device may receive an input adjusting a baseline activity level for the user within an application running on the user device and associated with the wearable device. The user device may compute a target activity level for the user based at least in part on the adjusted baseline activity level and the computed recovery metric for the user, and cause a graphical user interface (GUI) of the user device running the application to display the computed target activity level for the user.

Abstract: Provided herein are preservative composition of a preservative agent with a polyglycerol ester having a synergistic effect which allow for a reduction in the amount of the preservative agent necessary to be an effective preservative in an end-use formulation.

Abstract: Provided herein are preservative compositions containing a preservative agent with an alkylene glycol ester. Also provided are method for increasing the efficacy of preservative agents and methods for reducing the minimum amount of preservative agent needed for effective preservation activity in end-use formulations.
