Regulatory status

 

Use as pharmaceutical excipient:

SILFAR® 500 complies with the requirements set down in the monographs Dimeticone (EP) and "Dimethicone" (USP / NF).
Wacker explicitly rules out the use of SILFAR® 500 for parenteral applications.

 

Direct Food additive:

SILFAR® 500 is listed in the Regulation (EC) No 1333/2008 Annex II and III as amended by Regulations (EU) Nos
1129/2011 and 1130/2011 as E 900 polydimethylsiloxane. It meets the purity requirements as laid down in Regulation (EU)
No. 231/2012 and is therefore approved as direct food additive within the EC under observance of the use restrictions in
force for polydimethylsiloxane (E 900). SILFAR® 500 is certified according to HACCP principles. Hence, it meets the
requirements on food hygiene in accordance with Regulation (EC) No. 852/2004.

commodities that have contact with food.

 

SILFAR® 500 is listed under PM-Nr. 76721 in Regulation (EU) No. 10/2011 as an additive for plastic materials to come into
contact with food and meets the specifications under column (4) and (10). The product is not subject to a specific migration
limit (SML).

 

SILFAR® 500 is suitable for use under FDA 21 CFR as follows:

 

§175.105 (ADHESIVES),

§175.300 (RESINOUS AND POLYMERIC COATINGS),

§176.170 (COMPONENTS OF PAPER AND PAPERBOARD IN CONTACT WITH AQUEOUS AND FATTY FOODS)

§176.180 (COMPONENTS OF PAPER AND PAPERBOARD IN CONTACT WITH DRY FOOD).

§176.200 (DEFOAMING AGENTS USED IN COATINGS)

§176.210 (DEFOAMING AGENTS USED IN THE MANUFACTURE OF PAPER AND PAPERBOARD)

§177.1210 (CLOSURES WITH SEALING GASKETS FOR FOOD CONTAINERS).

§177.2800 (TEXTILES AND TEXTILE FIBERS).

§178.3120 (ANIMAL GLUE).

SILFAR® 500 is used both in the pharmaceutical and food sectors. In the pharmaceutical sector it is used in antiflatulence and antacid preparations. It acts as an antifoam agent to prevent or relieve flatulence in the alimentary canal and forms a protective lining on e.g. the gastric mucous membrane.

 

SILFAR® 500 may be used to make tablets and coated tablets. It is often combined with fermentation preparations.

 

SILFAR® 500 is also used to control foam in fermentation and downstream processes, such as active-ingredient extraction and solvent recovery, especially when USP/EP compliant products are mandatory.


In the food sector, SILFAR® 500 is used predominantly to control foam in lipophilic systems (foods rich in oil or fat, e.g. deep-frying oil) or for surface treatment. SILFAR® 500 also serves as the base material in the production of antifoams compliant with the regulations pertaining to food for human consumption.

Lagerung

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.
