[Object] To provide a composition for external use on the skin which can maintain the stability of the preparation by simultaneously mixing lecithin among various surfactants and the compound represented by the formula (1). The composition for external use on the skin is characterized in that the stability of the preparation can be maintained by simultaneously mixing lecithin among various surfactants and the compound represented by the formula 1 as an emulsifier. The compounding amount is not particularly limited, but lecithin can be adjusted to 0.01 to 10% to cope with various dosage forms, and the compound represented by the chemical formula 1 is preferably 0.1 to 20%, more preferably By setting the content to 0.2 to 5%, a sufficient surface activity assisting effect is exhibited, and the storage stability is greatly improved. |
