Cyclomethicone
What is Cyclomethicone?
Cyclomethicone is a type of silicone that is commonly used in personal care products. It is a clear, odorless liquid that helps create smoother, more spreadable textures in products. Cyclomethicone is made from cyclic siloxanes, which are compounds composed of silicone, oxygen, and other elements such as hydrogen.
This ingredient is primarily used to improve the feel of products on the skin, making them silky and light. It can also contribute to the spreadability and quick-drying properties of cosmetics and deodorants. The safety of cyclomethicone is still a topic of investigation, with ongoing studies into its potential impact on human health and the environment.
When you see cyclomethicone on a label, it indicates a product might rely on synthetic ingredients for texture and performance, most typically found in deodorants and moisturizers.
Commonly found in: Deodorant, Moisturizer, Hair care products, Makeup, Sun protection
