Cylomethicone is a type of silicone commonly used in cosmetics.
Cylomethicone is categorized as a volatile silicone, but it’s important to distinguish that the word volatile here doesn’t mean irritating to skin.
Instead, Cylomethicone means this kind of silicone evaporates quickly from skin’s surface, which is one of the advantages of formulating with Cylomethicone as it is able to evenly distribute other key ingredients without leaving a heavy or occlusive feel.
Cylomethicone also means you don’t have to worry about Cylomethicone “trapping” or “congesting” skin (as is also true for other silicones).
The velvety film left behind is permeable, meaning Cylomethicone doesn’t suffocate skin.
While Cylomethicone is typically the name that you’ll see on a product’s ingredient list, Cylomethicone also goes by cyclomethicone D5 or just D5 in research literature.

Inexpensive:
Cylomethicone is generally less costly than other silicone ingredients.
Therefore, a person may find that products containing Cylomethicone are more affordable.
Spreads easily:
Silicones are known for their slippery glide and smooth feel.
Cylomethicone gives products a silky smooth texture that applies easily and leaves a non-greasy finish.
Is inexpensive:
Because Cylomethicone is cheaper than other similar silicones, your products that contain Cylomethicone will also be more affordable as a result.
Evaporates quickly:
Cylomethicone is volatile, so it's often included in product formulations because Cylomethicone allows the products to dry faster.
Is lightweight:
Some silicones are heavy, but this one is particularly lightweight and used when a lighter feel is desired.
This trait is especially helpful in haircare products so as not to weigh down the hair strands.
Disperses heavier ingredients:
Cylomethicone works well when combined with heavier oils or silicones because it makes them easier to spread and provides a nice feel to the skin.
Seals hydration:
Cylomethicone forms a seal or barrier on the skin.
This barrier protects against transepidermal water loss (TEWL), which can lead to inflammatory conditions.
Cylomethicone may also work similarly when used on the hair by coating the hair shaft.
The molecular structure of silicones (large molecules with wide spaces between each molecule) means that the barrier they form is permeable, preventing the skin from "suffocating".
