The invention provides a non-contact (non-invasive) method for measuring quantity of sebum oil on skin or other substrate. The method includes applying fluorescent lipophilic dye to the substrate site of interest, illuminating the site at the excitation wavelength of the dye, and collecting fluorescent emission of desired wavelength of the dye. Because the measurements are truly non-contact, they can be made in real time on the same sites for any desired length of time.

The invention provides a non-contact process for measuring amount of sebum or oil on skin or other substrate. Process is preferably done in vivo because of ability to measure formation of sebum/oil on skin in real time.

A composition and method for inhibiting the extraction of transition metals from tableware washed in automatic dishwashers is described. The composition contains an aluminum species in which substantially all of the aluminum (III) ions are present as aluminum tetrahydroxide. A bleaching agent, a builder and optionally a surfactant and a silicate are present. The composition has a pH of less than about 10. A process for preparing the composition is also described.
