Alcohol foam is a strong antifoam that is chemically based on fatty acids and is actually a type of silicone-free diffuser that has foam control properties and has no side effects.
EO / PO alcohol-based antifoams contain polyethylene glycol and polypropylene glycol copolymers. They are delivered in the form of oils, water solutions or water-based emulsions. EO / PO copolymers usually have good dispersion properties. Alcohol antifoams consist of the suspension of fatty alcohol particles in an aqueous phase.
