Slide 2
Foam What is Foam?
Types of Foam
- 2 phase (colloidal) system of vapor dispersed in liquid - Thermodynamically unstable - Pure liquids do not foam - Surfactants help stabilize foam and entrained air
Vapor
Foam
Solution
Surfactant
Tetrahedral Foam (dry) Cellular Foam (wet) Entrained Air (microfoam)

Slide 3
Why is it important to eliminate foam? Laundry
Air entrainment in washing machines occurs: – When the laundry is lifted out of the washing liquor by the carrier baffles situated inside the drum
Commercial Laundry
– When the laundry falls back into the washing liquor – When the washing liquor flows through the perforations in the washing drum
Too much foam results in: – Insufficient contact between the laundry and the washing liquor. The foam acts like a cushion which reduces mechanical washing action effectively eliminating the benefit of tumble washers. – Overflow and insufficient rinsing leaving fabric sticky which can lead to re-soiling.

Slide 4
Why is it important to eliminate foam? Warewashing (Automatic Systems)
Warewashing
Foam generation occurs from: – Circulation of rinse water/surfactant/soil – Pumps mixing at high rpm to circulation jets – Mechanical shear of solution on dinnerware and flatware
Too much foam results in: – Inefficient operation of the automatic system (poor cleaning) – Problems with residue – inefficient rinsing – increased filming and spotting

Slide 5
Why is it important to eliminate foam? Clean-in-Place
Dairy Tank Cleaning
Foam generation occurs from: – Circulation of cleaning solution – Soil/protein (milk) breakdown – Break of the surface tension by mechanical action
Too much foam results in: – Cavitation of pumps which leads to poor pressure and premature pump wear – Excessive use of water for complete rinsing which slows production – Inefficient rinsing which leads to soil and cleaning solution residue deposition – Inefficient cleaning/contact of acidity/alkalinity in dairy tank – Premature/overfilling of waste tanks leading to labor downtime

Slide 6
Why is it important to eliminate foam? Bottle Cleaning
Bottle washing
Foam generation occurs from: – Circulation – Soil residues (build up)
Too much foam results in: – Cavitation of pumps which leads to poor pressure and premature pump wear – Foam overflow – Inefficient rinsing which leads to soil and cleaning solution residue deposition

Slide 7
Why is it important to eliminate foam? Recovery Tanks
Carpet Cleaning
Foam generation occurs from: – Original cleaning solution spray/mechanical action on substrate – Vacuuming of solution/soil from substrate
Too much foam results in: – Residue on substrate due to insufficient recovery – Over or premature filling of recovery tank – Downtime of labor for empting of tank
Floor Scrubbing (large scale)
Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Slide 8
Why is it important to eliminate foam? Medical Instrument Care
Instrument Care
Foam generation occurs from: – Hand washing intricate instruments – Circulation of cleaning solution – Protein and carbohydrate soils – Surfactant based cleaning solution
Too much foam results in: – Residue cross contamination – Safety concerns due to inability to view instruments in bath

Step 2
Spreading
Step 3
Bursting
Surfactant
Application
Defoamer Disrupt the surfactant layer beyond its ability to repair itself “Defoaming or Knockdown” Prevent the foaming surfactant from forming a stabilizing film “Antifoaming” Resist solubilization/emulsification by the foaming surfactants “Persistence”
Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Slide 11
Mechanisms of Defoaming Entering: The importance of particles
Large Particle
Particles of relatively large size easily bridge across film and cause bubble rupture Moderate particle size can bridge and rupture film but may be insufficient
Small Particle
Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Small particles are not likely to cause rupture
Slide 12
Mechanisms of Defoaming Spreading: The importance of the oil spreading oil
film-original thickness
thinning film
DEFOAMERS may spread across the air-bubble interface and sweep the surface clean of foam stabilizing species and may also promote film thinning. Both of these actions destabilize the bubble, causing a rupture. Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Slide 13
Optimizing entering and spreading “smart development of defoamers”
To rupture a foam film an oil/hydrophobic particle droplet must enter the aqueous phase into the air/water interface (entering) and then some oil from the droplet should spread on the solution air-interface (spreading)
Entering: – E = σAW + σOW - σOA > 0
Spreading – S = σAW - σOW – σOA > 0
Both the entering coefficient and the spreading coefficient must be positive for the corresponding processes to be energetically favorable
For both the entering and spreading coefficient to be positive, it is important to have a liquid with a low surface tension
Hydrophobic particles ease entry of the antifoam droplet in the foam walls or film interfaces, explaining the benefit of their addition in antifoam formulation

Foam What is Foam?
Types of Foam
- 2 phase (colloidal) system of vapor dispersed in liquid - Thermodynamically unstable - Pure liquids do not foam - Surfactants help stabilize foam and entrained air
Vapor
Foam
Solution
Surfactant
Tetrahedral Foam (dry) Cellular Foam (wet) Entrained Air (microfoam)

Slide 3
Why is it important to eliminate foam? Laundry
Air entrainment in washing machines occurs: – When the laundry is lifted out of the washing liquor by the carrier baffles situated inside the drum
Commercial Laundry
– When the laundry falls back into the washing liquor – When the washing liquor flows through the perforations in the washing drum
Too much foam results in: – Insufficient contact between the laundry and the washing liquor. The foam acts like a cushion which reduces mechanical washing action effectively eliminating the benefit of tumble washers. – Overflow and insufficient rinsing leaving fabric sticky which can lead to re-soiling.

Slide 4
Why is it important to eliminate foam? Warewashing (Automatic Systems)
Warewashing
Foam generation occurs from: – Circulation of rinse water/surfactant/soil – Pumps mixing at high rpm to circulation jets – Mechanical shear of solution on dinnerware and flatware
Too much foam results in: – Inefficient operation of the automatic system (poor cleaning) – Problems with residue – inefficient rinsing – increased filming and spotting

Slide 5
Why is it important to eliminate foam? Clean-in-Place
Dairy Tank Cleaning
Foam generation occurs from: – Circulation of cleaning solution – Soil/protein (milk) breakdown – Break of the surface tension by mechanical action
Too much foam results in: – Cavitation of pumps which leads to poor pressure and premature pump wear – Excessive use of water for complete rinsing which slows production – Inefficient rinsing which leads to soil and cleaning solution residue deposition – Inefficient cleaning/contact of acidity/alkalinity in dairy tank – Premature/overfilling of waste tanks leading to labor downtime

Slide 6
Why is it important to eliminate foam? Bottle Cleaning
Bottle washing
Foam generation occurs from: – Circulation – Soil residues (build up)
Too much foam results in: – Cavitation of pumps which leads to poor pressure and premature pump wear – Foam overflow – Inefficient rinsing which leads to soil and cleaning solution residue deposition
Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Slide 7
Why is it important to eliminate foam? Recovery Tanks
Carpet Cleaning
Foam generation occurs from: – Original cleaning solution spray/mechanical action on substrate – Vacuuming of solution/soil from substrate
Too much foam results in: – Residue on substrate due to insufficient recovery – Over or premature filling of recovery tank – Downtime of labor for empting of tank
Floor Scrubbing (large scale)
Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Slide 8
Why is it important to eliminate foam? Medical Instrument Care
Instrument Care
Foam generation occurs from: – Hand washing intricate instruments – Circulation of cleaning solution – Protein and carbohydrate soils – Surfactant based cleaning solution
Too much foam results in: – Residue cross contamination – Safety concerns due to inability to view instruments in bath

Entering
Step 2
Spreading
Step 3
Bursting
Surfactant
Application
Defoamer Disrupt the surfactant layer beyond its ability to repair itself “Defoaming or Knockdown” Prevent the foaming surfactant from forming a stabilizing film “Antifoaming” Resist solubilization/emulsification by the foaming surfactants “Persistence”
Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Slide 11
Mechanisms of Defoaming Entering: The importance of particles
Large Particle
Particles of relatively large size easily bridge across film and cause bubble rupture Moderate particle size can bridge and rupture film but may be insufficient
Small Particle
Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Small particles are not likely to cause rupture
Slide 12
Mechanisms of Defoaming Spreading: The importance of the oil spreading oil
film-original thickness
thinning film
DEFOAMERS may spread across the air-bubble interface and sweep the surface clean of foam stabilizing species and may also promote film thinning. Both of these actions destabilize the bubble, causing a rupture. Public: Defoamers Industrial & Home Care, FUN Division (Copyright Clariant. All rights reserved.)
Slide 13
Optimizing entering and spreading “smart development of defoamers”
To rupture a foam film an oil/hydrophobic particle droplet must enter the aqueous phase into the air/water interface (entering) and then some oil from the droplet should spread on the solution air-interface (spreading)
Entering: – E = σAW + σOW - σOA > 0
Spreading – S = σAW - σOW – σOA > 0
Both the entering coefficient and the spreading coefficient must be positive for the corresponding processes to be energetically favorable
For both the entering and spreading coefficient to be positive, it is important to have a liquid with a low surface tension
Hydrophobic particles ease entry of the antifoam droplet in the foam walls or film interfaces, explaining the benefit of their addition in antifoam formulation
