In general we recommend stirring 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.
The antifoam emulsion is best added undiluted. If it is necessary to dilute it before use a dilution in a ratio of 1 : 1 to 1 : 5 with water is recommended. Dilutions should be used within several days. Dosage-pumps should not have high shear forces. The typical dosage is in the range of 0.01 to 0.5 % and is best determined by preliminary tests. The respective food regulations must be followed.
Due to the ingredients contained, SILFOAM® SE 2660 is recommended for food and food contact applications.
Application information
Regulatory Status Europe
1. Use for food processing Europe:
SILFOAM® SE 2660 is a silicone fluid emulsion based on E 900 and may only be used as a processing aid for food.
Therefore, it has to be ensured by the producer of the foodstuff, that only technically unavoidable traces of SILFOAM® SE 2660 remain in the final food.
2. Contact with food:
The ingredients of SILFOAM® SE 2660 are contained in the positive lists of the following regulations for essential commodities intended to come into contact with food:

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 specific limits e.g. on migration/extraction resides with the manufacturer of the finished product.
