Abstract

See full text

Disclosed are: a method for suppressing adhesion of air harmful substances, including applying a metal oxide (A) having an average primary particle diameter dA of 800 nm or less to skin in an amount of 0.03 mg/cm2 or more to suppress adhesion of air pollutants to the skin, and a method for suppressing adhesion of air pollutants, including applying an external preparation to skin to suppress adhesion of air pollutants to the skin, wherein the external preparation contains the component (AI), and the component (BI), the component (BII) or the component (BIII), and the ratio by mass of the content of the component (BI), the component (BII) or the component (BIII) to the content of the component (AI) in the external preparation each falls within a specific range. Component (AI): a hydrophobized metal oxide having an average primary particle diameter dAI of 800 nm or less. Component (BI): an ester oil. Component (BII): a nonvolatile hydrocarbon oil. Component (BIII): a nonvolatile silicone oil.
