CAS No-541-02-6, 63148-62-9, 156065-02-0

Cyclopentasiloxane is a silicone regularly used in cosmetic products. It’s commonly found in medical implants, sealants, lubricants, and windshield coatings.

D5 is colorless, odorless, non-greasy, and water-thin. It doesn’t get absorbed into the skin. Rather, it evaporates quickly away from it. This property makes it a useful ingredient in cosmetic products that need to dry quickly, like antiperspirants and hair sprays.

It also has lubricating properties. This gives a slippery and silky feeling when applied to the skin and hair and allows the product to spread more easily.
