What is Cyclopentasiloxane?
Cyclopentasiloxane may have a long name that's hard to pronounce, but it's actually a common ingredient in a broad variety of products. This ingredient is commonly called D5 for short and may appear that way on the label of your favorite skincare products and cosmetics. This silicon-based compound is part of a larger category called cyclomethicone. It functions well as an emollient and comes in a colorless and odorless liquid format. You may see it listed on the label of an array of hair care, skincare, and other personal care products.
What is Cyclopentasiloxane in Hair Products?
While some shampoos may be tough to get your hair clean, those that contain cyclopentasiloxane should leave your hair feeling silky, smooth, and non-greasy. This ingredient evaporates quickly, so it may also help your hair dry faster after you get out out of the shower. It's also extremely lightweight, which is perfect to help prevent your hair from feeling limp and weighed down. The smooth feel of cyclopentasiloxane allows shampoo and conditioning products to spread evenly on the hair and scalp while it feels nice to the touch as it coats the hair shaft to keep it silky and hydrated. Finally, this ingredient helps seal in hydration, helping to keep your hair soft and smooth while keeping it moisturized to prevent frizz.
What is Cyclopentasiloxane in Cosmetics?
Cyclopentasiloxane is often added to cosmetics like foundation and face creams thanks to its ability to make textures feel smooth to the touch and leave a silky layer behind. For face and eye makeup, this ingredient allows lipsticks and liquid eyeliners to dry quickly so that they stay in place for long wear. For heavier foundations, it helps products spread more easily so they feel nice on the skin instead of heavy or cakey. Just like in hair products, cyclopentasiloxane helps to seal in hydration for soft, moisturized skin.
