Menadione

Product Description

Green Stone Swiss supplies high-purity Menadione (Vitamin K3, CAS 58-27-5) through direct factory channels for cosmetic OEM manufacturers developing targeted eye-care and redness-correction treatment lines.

This lipophilic vitamin K compound supports antioxidant defense and modulates the appearance of periorbital vascular discoloration and facial redness in topical oil-phase and emulsion matrices.

Formulators specify menadione at low ppm levels in eye gels, couperose serums, and post-exposure calming treatments where vitamin K actives address appearance-focused eye and redness concerns in export skincare portfolios.

Key Benefits & Applications

Menadione delivers targeted vitamin K activity for eye-area and redness-appearance applications at controlled low use levels.

• Antioxidant Defense: Quinone structure scavenges oxidative species in lipophilic antioxidant eye and face serums.
• Eye Area Conditioning: Supports periorbital skin appearance in dedicated eye gels and treatment creams.
• Periorbital Vascular Support: Helps reduce the appearance of dark circles linked to visible vascular shadows under eyes.
• Redness Appearance Modulation: Suits couperose-prone and post-exposure redness correction serums at low inclusion.

Formulation Guidelines

Use micro-doses in protected packaging; prioritize oil phase or liposomal delivery for stability.

• Recommended use level: 0.01–0.1% in eye care; 0.005–0.05% in facial redness serums
• Optimal formula pH: pH 5.0–6.5 in O/W emulsions; avoid high-alkaline systems
• Processing: Dissolve in oil phase or ethanol pre-mix; add below 40°C; nitrogen blanket preferred
• Compatibility: Compatible with lipids and liposomes; separate from strong oxidizers and reducing agents
• Caution: Photosensitive—use opaque or amber packaging; confirm regulatory allowance per target market
• Synergy: Pair Acetyl Tetrapeptide-5 at 3–5 ppm with menadione in periorbital gel-creams for puffiness appearance.
