The use of Coolade as a nonionic and low-foaming surfactant enables an ozonolysis of alkenes in water to provide carbonyl products in good yields. During the ozonolysis reaction, water molecules intercept the Criegee intermediate to provide a hydroxy hydroperoxide intermediate that decomposes to the carbonyl compound without the need for a reductant.
