The invention relates the use of pyroglutamic acid esters, which can be produced by esterifying alcohols having from 1 to 100 hydroxyl groups with pyroglutamic acid and/or glutamic acid, with the provision that the alcohol has no more than one ester group or no more than 100 carboxylic acid group, in quantities of from 0.01 to 2% by weight for preventing the formation of gas hydrates in aqueous phases that are connected to a gaseous, liquid or solid organic phase.
