An object of the present invention is to provide emulsified skin external preparations and cosmetics which contain a branched acyl carnitine and have excellent emulsion stability. An emulsified skin external preparation according to the present invention includes 0.01 to 10% by mass of a carnitine derivative represented by the following Formula (1) and/or a carnitine derivative salt represented by the following Formula (2), and 0.01 to 20% by mass of a nonionic surfactant.
In Formula (1), R 1 and R 2 are each independently a C1-18 optionally branched, saturated or unsaturated aliphatic hydrocarbon group. In Formula (2), R 1 and R 2 are the same as in Formula (1), X - is a specific anion and Y + is a specific cation.
