A cosmetic composition and an emulsion composition respectively comprising 0.1 to 99 weight % of an oily component and 99.9 to 1 weight % of a watery component are are provided and the oily component in the compositions comprises 85 or more weight % of cis-.DELTA.9-octadecenoic acid or derivatives thereof and contains 90 weight % or more of a cis-.DELTA.9-alkenoic acid or derivatives thereof and 10 weight % or less of fatty acids other than the cis-.DELTA.9-alkenoic acid, derivatives thereof or other oily components. The cosmetic composition showing superior feeling in use and superior storage stability than conventional products and the emulsion composition showing superior stability of emulsion than conventional products can be provided because the oily component contains cis-.DELTA.9-octadecenoic acid or derivatives thereof in a high concentration.
An emulsion composition which comprises 0.1 to 99 weight % of a first component and 99.9 to 1 weight % of a second component which is water soluble, the first component comprising 85 or more weight % of a cis-.DELTA.9-octadecenoic acid or a derivative thereof, included within 90 weight % or more of a cis-.DELTA.9-alkenoic acid or a derivative thereof, wherein the first component is either insoluble in the second component, dissolved in the second component or emulsified in the second component.
