Objectives Hair sprays apply fixative ingredients to provide hold to a hair style as well as weather resistance and optical properties such as shine. Generally, sprays distribute fine particles containing polymeric ingredients to form a thin film on

Background/purpose: Age perception is based on a number of facial attributes such as wrinkles, skin gravity effects, feature lines, and skin optical appearance. The colorimetric and optical diffusion properties of skin have been compared with the con

In the traditional concept, a stable Langmuir monolayer can be formed from amphiphilic molecules at the air−water interface with their hydrophobic alkyl chains oriented toward the air and the polar moieties embedded in the water. The intermolecular

The successful incorporation of chromophores in a sol–gel matrix requires a careful study of their interaction with the gel environment. Photoacoustic spectroscopy is used to probe chemical changes in the direct neighborhood of dopant molecules in

The technique of pulsed photoacoustic spectroscopy was used to investigate the diffusion of chromophores in human skin. The kinetic of diffusion has been studied for five solutions at different concentrations in a mixture of chromophores, as used in

The gelation process of a sol−gel material is monitored for the first time in a detailed manner by use of a photoacoustic spectroscopy derived methodology. Measurements of the acoustic response spectrum of a sol−gel material during the transition
