SILFOAM® SE 2
SILFOAM® SE 2 is a milky, comparatively viscous antifoam emulsion.
SILFOAM® SE 2 is suitable for use under the following regulations for packaging materials and articles intended to come into contact with food:
- Regulation (EU) No. 10/2011 provided that the Specific migration limit (SML) of 1.8 mg/kg for the emulsifier is met.
- Recommendations of the BfR: XIV. Plastic Dispersions, XV. Silicones and XXXVI. Paper & Paperboard
- FDA 21 CFR § 176.170, 176.180, 176.200 and 176.210
Regulatory sanctioning of the ingredients in a product does not imply that the finished product manufactured from those ingredients is considered safe by regulatory bodies. Responsibility for compliance with the above mentioned requirements resides with the manufacturer of the finished products
In general we recommend to stir the emulsion before use (approx. 3 minutes with a propeller stirrer at 200 – 400 rpm). But be cautious: too high shear can break the emulsion.
SILFOAM® SE 2 can be used undiluted or in dilutions (e.g. 1 : 10 - 1 : 50) made with cold water. It is added either in portions or continuously to the process or product concerned. The antifoam emulsion disperses readily without the need for high shear forces. Dilutions should be used up as soon as possible.
SILFOAM® SE 2 is used in different fields, including cosmetic and food contact applications. SILFOAM® SE 2 contains broad-spectrum, physiologically safe active ingredients based on polydimethylsiloxane / silica it may be widely used for controlling foam in systems and products which themselves might come into indirect contact with foodstuffs, such as cleaners for food containers, conveyor systems, storage surfaces. Its efficient emulsifier system supports the product in other areas as well, such as the manufacture of dispersions for food applications, agrochemical formulations, biotechnological processes, the production of packing materials and their coatings as well as wastewater treatment from foodstuffs production. Moreover, SILFOAM® SE 2 readily lends itself to use for effective foam control in alcohol fermentation processes in which the alcoholic fraction is distilled off afterwards.
Minimum temperature allowed during storage and
transportation: 0 °C
The "Best use before end" date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
