• Silicones are versatile substances. In many cases, it is therefore desirable to apply silicones. Mention may be made, for example, of hydrophobing, greasing, lubricating or impregnating surfaces, and also the hydrophobing or fatting of fibrous substrates, in particular of water-swellable substrates such as, for example, tanned animal hides. However, due to the circumstances, it is desirable to carry out the application in the aqueous phase and not using organic solvents, since organic solvents may, for example, be readily combustible or have physiologically unfavorable properties. It is therefore necessary to disperse or emulsify the hydrophobic substances to be applied.
• Such emulsions should have advantageous properties, which include in particular the stability, that is they should not be measurable or only segregate within a long time.
• the production of so-called stable emulsions and dispersions of silicones is thus an important field of work.
• emulsifier For the preparation of stable emulsions and dispersions therefore the choice of the emulsifier plays a central role. Many common emulsifiers are now undesirable because they adversely affect the wastewater, they may for example have a high COD (Chemical Oxygen Demand) or BOD (biological oxygen demand), which makes wastewater disposal more expensive.
