Overview

Cyclomethicone is a broad term for various types of cyclic silicones, which are circular in structure – as opposed to linear, like the close cousin dimethicone.

This ingredient is generally a blend of different sizes of cyclic silicones and is known for its emolliency, where it leaves a smooth, non-greasy feel when applied to the skin or hair. Although it is a synthetic ingredient, cyclomethicone is used widely as a lightweight conditioner for the skin and hair.

Unlike other types of oils, it does not leave any residue on the skin, which is part of what makes it so popular. Finally, cyclomethicone is also frequently used as a carrier fluid for other oils, due to its lubricity and high spreadability.
