Cyclopentasiloxane (D5) is a volatile, low-viscosity silicone fluid widely used in personal care and cosmetic formulations. Known for its fast-evaporating nature and smooth, non-greasy feel, this ingredient enhances product spreadability and provides a luxurious, silky texture. Ideal for leave-in hair treatments, skin care, and deodorants, Cyclopentasiloxane (D5) offers excellent compatibility with other cosmetic ingredients and is a key component in lightweight, non-tacky formulations.
Key Features & Benefits
- Volatile, Lightweight Silicone: Quickly evaporates without leaving a residue, ideal for non-greasy, matte finishes.
- High Spreading Ability: Provides excellent wetting and spreading properties, making thicker ingredients glide smoothly.
- Detackifier: Reduces the tackiness of other ingredients like glycerin, improving product feel.
- No Cooling Sensation: Evaporates cleanly without a cooling effect, making it comfortable on the skin.
- Versatile Usage: Works well in hair care, skin care, deodorants, and delivery systems for active ingredients.
