Curcuma Longa (Turmeric) Root

Product Description

Green Stone Swiss supplies Curcuma Longa (Turmeric) Root Powder through direct factory channels, delivering curcuminoid-standardized turmeric rhizome with batch HPLC documentation for cosmetic OEM and Ayurvedic-inspired skincare manufacturers.

Curcumin, demethoxycurcumin, and bisdemethoxycurcumin from Curcuma longa root modulate tyrosinase activity, scavenge ROS, and suppress NF-κB-linked inflammatory signaling in topical phytochemical literature.

Formulators deploy this fine root powder in brightening masks, golden scrubs, and curcuminoid serums where visible yellow actives support clean-label antioxidant and even-tone positioning in export personal care lines.

Key Benefits & Applications

Curcuma longa root curcuminoids deliver multi-pathway antioxidant, brightening, and calming activity in rinse-off and leave-on formats.

• Curcuminoid Antioxidant Defense: Curcumin-class polyphenols neutralize lipid peroxidation in antioxidant mask and serum systems.
• Free Radical Neutralization: Scavenges ROS linked to photo-stress and dull skin appearance.
• Anti-Inflammatory Signaling: Modulates NF-κB-linked redness appearance in post-exposure calming treatments.
• Radiance Enhancement: Revives tired, uneven skin appearance in golden glow mask and essence formats.
• Melanin Pathway Modulation: Curcuminoids help reduce the appearance of hyperpigmentation in brightening care lines.
• Tyrosinase Modulation: Inhibits tyrosinase activity supporting even-tone toners and spot-care gels.

Formulation Guidelines

Predisperse powder; control pH and light exposure to protect curcuminoid activity.

• Recommended use level: 0.5–3.0% in leave-on; 3.0–10.0% in rinse-off masks and scrubs
• Optimal formula pH: pH 4.5–6.0 for curcuminoid stability in aqueous dispersions
• Processing: Premix in glycerin or oil before water addition; shear below 40°C
• Compatibility: Compatible with niacinamide and panthenol; avoid strong oxidizers and high alkali
• Caution: Yellow staining on skin, fabric, and packaging; use opaque containers for leave-on
• Synergy: Formulators often co-add Niacinamide at 3–5% to curcuminoid-rich turmeric in brightening essence toners.
