Optionally, the composition comprises an anti-foaming agent, corrosion inhibitor, an anti-freeze agent, or combiantions thereof.
An anti-foaming agent may also be utilized for the prevention or suppression of foam during the mixing process.
After adding a few drops of silicone anti-foaming agent, 6,5 ml of sodium hydroxide solution as specified in point 4(b) is added to the extract and steam distillation begins immediately.
A powdery food defoamer containing a linear fatty acid monoglyceride, lecithin, a water dispersibility improver and powdery dextrin, and a food material containing the same.
The defoamer permits a stable admixture formulation and helps to achieve a controllable level of entrained air in a concrete mix.
An exemplary admixture system for cementitious compositions, comprises a polycarboxylic acid type water reducer and a tertiary amine defoamer having an average molecular weight of 100-1500 and more preferably 200-750.
Shelf life of silica based defoamer composition is improved by adding oil soluble resins and optionally aliphatic fatty acids to retard separation and to inhibit settling.
The invention addresses the problem of providing a defoaming agent for food, which has a defoaming ability equal to or higher than that of a silicone resin-based defoaming agent.
According to the invention, the defoaming agent is preferably a silicon antifoaming emulsion which contains physiologically indifferent active constituents based on polydimethylsiloxane/silica.
The aqueous composition is derived from a concentrate which includes a defoaming agent, a demulsifying agent, and optionally a stabilizing agent suitable for stabilizing the concentrate as an aqueous emulsion.
In one embodiment, the defoaming agent is dispersed in carrier solvent and the concentrate further includes an emulsifying agent suitable for emulsifying the carrier solvent in water.
Said aerosol foam comprises a content of at least one cationic, amphoteric or zwitterionic polymer, at least one surfactant, at least one defoaming agent, an aqueous or aqueous-alcoholic solvent system and at least one aerosol propellant.
An antifoam additive for hydrocarbon oils and in particular fuel oils comprises the combination of an antifoam agent and an ashless dispersant.
Provided is an antifoaming agent for use in fermentation.
The organic carrier and antifoam are enclosed by a coating layer.
The stabilizer consists of lime, sodium formate, and an antifoaming agent.
Further, the antifoaming agent exhibits strong antifoaming effect against the foaming of a fermentation medium.
In accordance with the invention, compressive strength is significantly increased without substantially reducing weather resistance by adding an antifoam agent to the mixture prior to setting into a solid.
The present invention also provides detergent compositions containing said foam control agent.
Also disclosed is its use for defoaming paint coagulation baths.
The fracturing fluid may additionally comprise a proppant, fluid loss additive, and/or a foam breaker.
With the optional dosing device, special defoaming components are added to the wash water.
The spraying device (80) may, for example, receive treated water along a line (128), possibly with the addition of an anti- foaming agent.
With the optional dosing device, special defoaming components are added to the wash water.
The present invention regards a superfluidifying additive for cementitious compositions, comprising an acrylic superfluidifier, an ammonium salt, at least one surfactant, and possibly an antifoaming additive.
A hairspray composition is provided with improved combability, spray efficiency and anti-foaming properties.
The test solution may be an aqueous-alcohol solution having a chemical thickener, and preferably includes a de-foaming agent, a bactericide/fungicide and a fragrance.
This antifoaming agent is highly dispersible in water, so that the resulting dispersion does not suffer from sedimentation or oil droplet formation even when heated.
TMMD is used as an antifoam and emulsifier in the production of adhesives and has a toxicity class III, which is very high.
Antifoam particles for incorporation into a particulate detergent product comprise a high viscosity silicone antifoam absorbed onto a porous, particulate organic carrier exemplified by cellulose or wood flour.
We use 100% peanut oil that is refined and contains only enough preservatives (less than .004%, so that the oil doesn't foam when we put our fries in!).
