Abstract: The invention provides novel devices to allow for the accelerated evaluation of the impacts of light exposure on the contents of the packaging system. Through this approach and using the methods described herein, it can be determined how the components of a complete package system perform collectively to influence its photoprotective performance enabling a first ever method to quantitate these impacts. The use of this device with the methods described herein will allow for package designs to be optimized for the photoprotection performances, for the impacts of packaging production defects to be explored, and for the influence of packaging form (e.g., surface area to volume ratio) to be determined. Such device capabilities allow a first ever means to provide simulated retail, isothermal light exposures to complete package systems.

Abstract: The invention provides novel methods to place a complete package system filled with a sample into a light exposure chamber as a complete unit with periodic monitoring of the contents of the packaging system. Through this approach, it can be determined how the components of a complete package system perform collectively to influence its photoprotective performance enabling a first ever method to quantitate these impacts. In turn this will allow for package designs to be optimized for the photoprotection performances, for the impacts of packaging production defects to be explored, and for the influence of packaging form (e.g., surface area to volume ratio) to be determined. Such capabilities allow a first ever means to optimize package systems for photoprotective performance.

Abstract: The present invention relates to a process and apparatus for quantifying solid residue on a sample. The process includes using a solid substrate and an aerosolizing device, adding a solid material to the aerosolizing device, forming a particle cloud of solid particles, wherein at least 1% of the mass concentration of solid particles have a mass median aerodynamic particle diameter up to about 10 ?m, thus applying the solid particles to the solid substrate(s) to form treated substrate(s), maintaining at a temperature of from about 30 to about 120° C. for at least a portion of the process, and removing a portion of solid particles from the treated substrate(s), and analyzing said at least one sample. The present invention further comprises an apparatus for applying solid particles to a substrate. The process can be used, for example, to analyze the dirt pickup resistance of a solid sample.
