"The anti-foaming agent Simethicone is a complex mixture of high molecular weight polydimethylsiloxane (PDMS) oligomers (approximately 92%) with particulate silicon dioxide added to enhance the defoaming properties of the silicone oil. The PDMS is characterised in terms of its viscosity of about 60 000 centiStokes, corresponding to an average molecular weight of about 27 000 Daltons."
