Fullerenes

Product Description

Green Stone Swiss supplies cosmetic-grade Fullerenes under a direct factory model, with GMP-aligned quality control, batch documentation, and sample support for premium antioxidant skincare formulators.

Fullerenes (INCI: Fullerenes; CAS 99685-96-8) are cage-like carbon molecules typified by C60 (buckminsterfullerene). CosIng lists antimicrobial and skin-conditioning functions; in advanced leave-on formulas they are valued for radical/ROS-handling performance discussed in open literature and for supporting antioxidant-focused product concepts.

They are typically supplied as powder or pre-dispersed concentrates for serums, essences, and emulsion systems. Final particle-size characterization and regional nanomaterial rules must be confirmed for each grade before market placement.

Product Specification

• INCI Name: Fullerenes
• CAS No.: 99685-96-8

• Molecular Weight: 720.64 g/mol (C₆₀)
• Appearance: Black to dark brown powder (or as specified dispersion)
• Purity: ≥99% Typical (C₆₀ grade; COA Available upon request)
• Solubility: Poorly soluble in water; typically used via oil-phase or specialized dispersions (details Available upon request)
• Suggested pH: Compatible with common cosmetic pH systems after dispersion; confirm in final chassis
• Storage: Store sealed, cool, and protected from light and moisture

Key Benefits & Applications

Fullerenes are a high-purity C60 carbon active for professional antioxidant and skin-conditioning cosmetic systems.

• Supports CosIng skin-conditioning positioning in premium leave-on skincare
• Provides CosIng antimicrobial function class for formulation concepts requiring that claim pathway
• Widely used in antioxidant-focused serums and essences for radical/ROS-management narratives
• Suitable for advanced emulsions, ampoules, and concentrate-based skincare formats when properly dispersed
• Typical use level: Formulation-dependent; finalize by grade (powder vs dispersion), particle-size profile, and regional assessment

Formulation Guidelines

Use these notes to disperse Fullerenes stably and remain compliant with regional nanomaterial expectations.

• Suggested Use Level: Formulation-dependent; confirm finished-product safety assessment, labeling, and any nano-related notification requirements
• Dispersion: Prefer validated pre-dispersions or high-shear oil-phase milling; avoid agglomerates; verify particle-size distribution for the supplied grade
• Addition: Incorporate via oil phase or concentrate during cool-down when heat-sensitive co-actives are present; confirm color uniformity
• Compatibility: Screen with antioxidants, emulsifiers, and UV filters; monitor settling, staining, and long-term dispersion stability
• Regulatory: EU SCCS has flagged data gaps for certain fullerene/nano forms—do not assume blanket EU nano clearance; document grade specs for each market
• Combine with Tocopherol for complementary oil-phase antioxidant support in premium emulsion and serum systems.
