• Molecular Formula: C₃₀H₄₈O₃
• Source: Derived from olive leaf, ligustrum, or other plant triterpenes

Functional Role in Cosmetic Applications

Oleanolic Acid is a pentacyclic triterpenoid valued in modern cosmetic formulations for its ability to rebalance oily skin, reinforce barrier function, and support calm, even-toned appearance. It is often used in active complexes targeting skin exposed to environmental stress or hormonal imbalance.

• Sebum Modulation: Suitable for mattifying and pore-refining formulations
• Barrier Reinforcement: Contributes to improved skin integrity and resilience
• Ideal for Oily or Combination Skin: Often included in purifying and balancing products
• Plant-Derived: Suitable for clean beauty and botanical performance ranges

Typically found in skin-balancing serums, clarifying creams, urban care emulsions, and scalp formulations. Available in bulk format for use in both R&D and full-scale production.

Recommended Use Levels

• Mattifying or oil-control formulas: 0.05–0.3%
• Balancing emulsions and masks: 0.1–0.5%
