Although the negative effects of particulate matter on the respiratory system are well documented,until now their impact on the skin has not been investigated in depth. Working on the assumption that keeping particulatematter off skin is the first line of defense against pollution-induced damage, BASF has developed a novel standardized testmethod to assess the effects of typical cosmetic ingredients, i.e. polymers, emulsifiers, and emollients, on the adhesion andremovability of pollutants. The findings have been used to create formulations that exhibit clear anti-adhesion and rinse-off(removability) effects.
