Silico® – Your Trusted Manufacturer of Cyclomethicones

Silico® – Cyclomethicone is a group of volatile silicones (D4, D5, and D6) widely used in cosmetic formulations for their rapid evaporation and smooth, non-greasy finish. These silicones leave a silky texture on skin and hair, improving product application and spreadability.

Key Benefits:

  • Fast Evaporation: Cyclomethicones quickly dissipate, providing a dry, non-tacky feel.

  • Skin and Hair Conditioning: Adds shine to hair and a smooth texture to skin.

  • Solvent Capabilities: Enhances ingredient stability and spreadability.

Common Applications:

  • Skin Care: Used in moisturizers, sunscreens, and lotions for smooth, residue-free application.

  • Hair Care: Adds shine and reduces frizz in conditioners and serums.

  • Cosmetics: Improves texture and even distribution in primers and foundations.

Environmental Considerations: Due to potential environmental impact, regulations have been placed in some regions to limit cyclomethicone use, especially in rinse-off products.

Cyclomethicones offer excellent sensory and functional benefits in cosmetics, but manufacturers are encouraged to consider alternative ingredients to minimize environmental impact.

How to Choose Cyclomethicone for Your Formulation

Cyclomethicones, such as D5 (Decamethylcyclopentasiloxane) and D6 (Dodecamethylcyclohexasiloxane), are widely used in personal care products for their lightweight, non-greasy feel and quick evaporation.

Key Factors to Consider:

  • Evaporation Rate: D4 evaporates the quickest, followed by D5, and D6 is the least volatile. Choose based on desired drying time and finish.

  • Regulatory Compliance: D4 is restricted in many regions due to environmental concerns. D5 has usage restrictions in some areas, while D6 is widely accepted.

  • Application: D5 and D6 are ideal for leave-on products like lotions and hair serums due to their conditioning benefits.

For most applications, D6 provides an optimal balance of performance and regulatory compliance. Always consider local regulations and product needs when selecting.
