Wetting

Wetting effects of emulsifier moisten the solid surfaces.
Solid material is mixed with an emulsifier or its surface is spread with it, the surface then becomes hydrophilic.

For example, chewing gum is apt to stick to teeth.

Adhesion to natural teeth does not occur easily because the enamel is hydrophilic and always wet, whereas the adhesion to artificial teeth, occurs easily. We can prevent adhesion by wetting the surface of chewing gum by adding emulsifier.

Bacteriostatic effects
