Provided are a siloxane composition, said siloxane composition showing physical properties between a dimethyl polysiloxane oil and a gelatinous crosslinked siloxane and being fluid or becoming fluid when dissolved in a solvent, and a method for producing the same. The siloxane composition, which is obtained by subjecting specific starting organopolysiloxane materials to an addition reaction in a large excess (i.e., 8 times by mass or greater as much as the starting materials) of a solvent, comprises a crosslinked organopolysiloxane, said crosslinked organopolysiloxane having a weight-average molecular weight of 5,000-300,000,000 and containing 0.1-50 mol of silethylene bond per 1,000 mol of siloxane unit, dissolved in the solvent. |
