Cosmetics Pore Size Distribution Test

Gas Adsorption Analysis, specifically physisorption, is a technique used to study the surface area and porosity of materials by measuring the amount of gas adsorbed at different pressures. Widely utilized in cosmetic industry, this technique informs the design of materials fo cosmetic products. The technique involves the adsorption of gas molecules, typically nitrogen, onto the surface of a pharmaceutical material at different pressures. As the pressure increases, the gas molecules fill the pores, allowing for the determination of pore sizes based on the amount of gas adsorbed.
