What is the difference between Acetylenic Glycol surfactant and Traditional surfactants?

1.Charge factor

Lonic surfactant: Charge stabilized foam.

VS

Acetylenic glycol: Non-ionic surfactants don’t require charge stabilization factors

2.Surface viscosity

Lonic surfactant:The higher surface viscosity is the more stable the bubble.

VS

Acetylenic glycol: The hydrophilic group is arranged horizontally, and the internal cohesion is small; the surface viscosity is small, and the foam stability is reduced.

3.Steric hindrance

Traditional surfactants: have large molecular weight and large steric hindrance, which prevents microbubbles from continuing to combine into large bubbles and break them.

VS

Acetylenic glycol:The space is small, and microbubbles are easily combined into large bubbles to enhance defoaming ability.
