Cyclomethicone and Silicone Gel Properties

Regarding your questions about Cyclomethicone and Silicone Gel:

• Cyclomethicone and "Silicone 345": Cyclomethicone, specifically Cyclopentasiloxane, is often referred to by trade names such as DC-345 or TSF-405. So, "Silicone 345" is likely a trade name for Cyclopentasiloxane.

• Heat Tolerance of Cyclomethicone: Cyclopentasiloxane is a volatile silicone, meaning it evaporates. Its boiling point is around 205°C. While it can withstand temperatures up to this point, it will start to evaporate significantly as it approaches this temperature.

• Silicone Gel and Heat: Silicone Gel is typically a dispersion of silicone elastomer in a silicone fluid (like Cyclomethicone or Dimethicone), not a solid material that melts at a specific temperature. Therefore, it does not have a melting point in the traditional sense. It is usually mixed into formulations by stirring or dispersing, not by heating to melt it. Heating is generally not required or recommended for incorporating silicone gels into formulations.

As mentioned in the forum reply, Silicone Gel is best mixed by stirring rather than heating.
