Ursolic Acid

Product Description

Green Stone Swiss supplies high-purity Ursolic Acid manufactured under strict GMP-aligned quality systems, ensuring consistent batch-to-batch performance for professional cosmetic and personal care brands worldwide. Our direct factory supply model delivers reliable bulk quantities with full technical documentation and free sample support.

Ursolic Acid is a pentacyclic triterpenoid used in cosmetics as a skin-conditioning active. In leave-on systems it is positioned for firmness-oriented and photo-aging care, where formulators look for a defined, oil-compatible marker rather than a botanical extract blend. It is poorly soluble in water and is typically handled as a pre-dissolved concentrate in ethanol or glycols before incorporation.

Demand for high-purity triterpenoid actives continues to grow in anti-wrinkle serums, firming emulsions, and daily photo-aging treatments. Cosmetic-grade Ursolic Acid remains a practical choice when brands want a single-molecule specification, HPLC-traceable purity, and predictable use levels in oil-phase or solubilized systems.

Key Benefits & Applications

Ursolic Acid is a defined pentacyclic triterpenoid used in firming, anti-wrinkle, and photo-aging cosmetic systems.

• Supports firmness-oriented leave-on formulas targeting visible slackness and loss of bounce
• Used in photo-aging care to help maintain a more even, resilient skin appearance under daily UV and environmental stress
• Fits anti-wrinkle serums, cream-gels, and eye-area emulsions that need a lipid-compatible active
• Pairs well with complementary triterpenoids and barrier lipids in multi-active anti-aging chassis
• Typical use level: 0.1–0.5% in leave-on formulations after pre-dissolution

Formulation Guidelines

Follow these guidelines to keep Ursolic Acid dispersed and stable in cosmetic systems.

• Suggested Use Level: Typical 0.1–0.5% in the finished formula
• pH Range: Suggested 5.0–7.0; confirm solubility after neutralization
• Addition: Pre-dissolve in ethanol or glycol; add to the oil phase or a solubilized concentrate; moderate heat is acceptable
• Stability: Protect from prolonged light and moisture; recheck for recrystallization in high-water systems
• Combine with Oleanolic Acid when a complementary pentacyclic triterpene is needed in the same firming or photo-aging chassis.
