Cyclopentasiloxane

CAS No-541-02-6

Cyclopentasiloxane or D5 is used in a wide variety of cosmetic products as it is known to evaporate and dry faster. Further, silicones and silicon-based products also repel water and glide easily (1). This is the reason why they are commonly used as ingredients in various cosmetics, lubricants, and sealants. In beauty products, cyclopentasiloxane is primarily used as a lubricant, solvent, and delivery agent, as it gives a very silky and slippery feeling when applied to the skin and hair. 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.
