Cyclopentasiloxane is a volatile silicone fluid used to improve spreadability and deliver a smooth, silky feel without heaviness.
It flashes off after application, leaving behind a dry-touch finish that helps reduce greasy feel and improves sensory.
It is widely used in hair serums, anti-frizz oils, heat-protection style blends, body oils, and lightweight silicone-based serums.
It also helps carry silicone gums and other oil-soluble ingredients for a more professional slip and gloss finish.
FEATURES
- Instant slip – improves spread and reduces drag immediately.
- Dry-touch finish – evaporates after application to reduce oily feel.
- Hair performance – boosts shine, reduces frizz, and improves combability feel.
- Carrier fluid – helps solubilise and deliver silicone gums and lipophilic ingredients.
BEST FOR
- Hair serums
- Anti-frizz oils
- Heat-protection serums
- Silicone body oils
- Dry-touch body serums
- Silicone-based primers
FORMULATION GUIDELINES
| INCI | Cyclopentasiloxane |
|---|---|
| Type | Volatile silicone fluid (dry-feel emollient/carrier) |
| Solubility | Oil soluble (silicone phase/oil phase) |
| SAP Value | N/A (silicone fluid, not a triglyceride oil) |
| Iodine Value | N/A (silicone fluid, no unsaturation value) |
| Use Rate | 2–70% typical, depending on product type. 5–30% is common in hair serums and dry-touch body oils. |
| Best Phase | Oil/silicone phase (anhydrous) or oil phase of emulsions designed to accept silicones |
| pH Compatibility | Not pH dependent. pH N/A for anhydrous systems. |
| Temperature Tolerance | Stable under normal processing. We recommend avoiding prolonged heating and adding below 60°C where possible to reduce losses from volatilisation. |
| Pro Tip | Use cyclopentasiloxane to reduce greasy feel and improve spread in hair oils and body oils. It is an excellent carrier for silicone gum blends to build gloss and anti-frizz performance. Choose packaging with a strong seal to reduce evaporation and viscosity drift during storage. |
| Appearance | Clear, colourless liquid |
| Stability Notes | Volatile. Evaporation over time can cause thickening and scent concentration. Confirm packaging compatibility and storage stability. |
| Storage | Keep sealed, cool and dry, away from heat and direct sunlight. |
