Please read further for details on that.įor example, the Cosmetic Ingredient Review (CIR) Panel reviewed dimethicone safety for use in cosmetics. And I did not find any negative health impact information in the US, European, or Canadian agency databases. Third, dimethicone is a well-studied ingredient so you can look it up in a number of different scientific, medical, and regulatory agencies, which I have done. Per the 2003 Cosmetic Ingredient Review (CIR) Expert Panel report, it has 3 CAS numbers:, 6, and. Second, to avoid confusing dimethicone with cyclic silicones, please know that dimethicone can be identified (like any ingredients listed in products) and therefore distinguished from cyclic silicones with CAS Registry numbers, unique identification numbers assigned by the Chemical Abstracts Service. You can learn more about the safety of cyclic silicones in my blog titled The Intriguing Story Of Cyclopentasiloxane. And I can say that with confidence because both linear and cyclic silicones are well-studied. Yes, I know that they share “-siloxane” in their names but that does not mean they share negative health side effects. But cyclic and linear silicones are different. Perhaps there is negative information about dimethicone due to confusing it with cyclic silicones such as cyclopentasiloxane (D5) or cyclotetrasiloxane (D4). What is dimethicone?įirst, its chemical name is polydimethylsiloxane (PDMS), and it is also known as linear silicone based polymer ( source). Here is what I have learned about this widely used ingredient. It takes a lot more time to do things this way, but it is my obsession to find the truth. But before I publish something, I always do my best to track down the original sources of information, so I am not simply repeating something that may not be true. There is a lot of misinformation out there! Once something is written, it can take on a life of its own. I say this because a lot of bloggers simply repeat what they read on the Internet. Therefore, when you hear scary claims about a product or an ingredient, I encourage you to ask for the sources of their information. I believe it is important to pass along only accurate information, so I turn to scientific and medical sources. To begin with, I formulate my opinions by reading scientific studies on the subject and do not just rely on hear-say.
