Sugar-based silicone surfactants are generally prepared by reacting (poly) siloxane containing active functional groups such as amino, epoxy, and hydroxyl groups with glucose derivatives.
The R & D staff first prepared hydroxyl-containing polyether-modified polysiloxane through hydrosilylation, and then reacted with glucose to prepare sugar-based silicone surfactants. They found that this type of sugar-based silicone surfactants had no irritation to eyes and skin. , Has excellent softness, softness, is a very mild type of surfactant, suitable for personal care products.
HAN and others prepared a series of sugar-based silicone surfactants by linking sugars and trisiloxanes with ethylenediamine, etc., and conducted surface activity studies. It was found that the surface tension of most sugar-based silicone surfactants was less than 25 mN. / m.
