Volatile cyclic silicone fluid for cosmetic formulations

CM 50 Cyclopentasiloxane (D5) is a colourless, volatile silicone fluid from the cyclomethicone group. You use it as a base fluid in personal care products. With a viscosity of 4.0 mm²/s and a surface tension of 18.0 mN/m at 25 °C, CM 50 spreads excellently, rubs in easily and leaves no oily residue. Its specific gravity is 0.95 g/cm³, its flash point (closed cup) 77 °C and its boiling point 205 °C. The cyclotetrasiloxane (D4) content is below 1.0 %.

Key benefits

Volatile carrier: evaporates and leaves no oily residue or build-up.
Excellent spreading: thanks to the low surface tension of 18.0 mN/m.
Silky skin feel: a soft, non-greasy finish.
Widely compatible: mixes with many cosmetic ingredients and dissolves well in most anhydrous alcohols.
Stable formulations: low use levels are sufficient.

Typical applications

✓ Antiperspirants and deodorants
✓ Hairsprays
✓ Skin creams and lotions
✓ Sticks, bath oils and sun care products
✓ Make-up and nail polish

Processing

Use CM 50 on its own or blended with other cosmetic fluids as a liquid base for other cosmetic ingredients.
CM 50 dissolves well in most anhydrous alcohols and in many cosmetic solvents.
In sticks, use CM 50 to balance volatility and spreading.
Keep containers closed as much as possible while working. CM 50 has a significant vapour pressure at room temperature.

Points of attention

✓ D5 falls under REACH Annex XVII, entry 70. Since 31 January 2020, wash-off cosmetics may contain no more than 0.1 % D5. For other cosmetics this limit applies from 6 June 2027. Since 6 June 2026 a general restriction also applies to D5 on its own and in mixtures, with a number of exemptions. Check in advance whether your application is permitted.
✓ Looking for an alternative for new formulations? Consider a linear, volatile dimethicone such as Silicone Oil 1.5 cSt or Silicone Oil 2 cSt.
✓ Take care at temperatures from 10 °C below the flash point of 77 °C. Keep containers closed and away from heat, sparks, open flames and other ignition sources.
✓ CM 50 has not been tested for, and is not considered suitable for, medical or pharmaceutical use.
✓ In its original unopened container at no more than 25 °C, CM 50 has a shelf life of 36 months from the date of manufacture. The expiry date is shown on the packaging. Never use an open flame to thaw frozen material.
