[PROBLEMS] It is possible to design a polyoxyethylene (PEG) -free prescription as a whole prescription without impairing the feeling improvement effect by diglycerin derivative-modified silicone because it is extremely excellent in emulsification and dispersibility in an oil phase alone. Provided are a diglycerin derivative-modified silicone, a surfactant / dispersant containing the same, an emulsifier for a water-in-oil emulsion, an external preparation or a cosmetic. The molecule contains a long-chain alkyl group as a lipophilic group, does not have an oxyalkylene structure having an average number of repeating oxyalkylene units of 2 or more as a hydrophilic group, and is a glycerin unit. Contains a diglycerin derivative-modified silicone characterized by having only a glycerin derivative group having an average number of repetitions of 1.1 to 2.9 and no other hydrophilic group in the molecule Composition, surfactant / dispersant containing the same, emulsifier for water-in-oil emulsion, external preparation or cosmetic.
