Ursolic acid

Ursolic acid (CAS 77-52-1), also known as urson, prunol, and malol, is a pentacyclic triterpenoid acid extracted primarily from apple peel, rosemary, and holy basil. It functions as a bioactive ingredient and antioxidant stabilizer across pharmaceutical formulations and personal care products.

In topical cosmetic formulations, it is incorporated into anti-aging creams and serums where its antioxidant activity helps protect against oxidative degradation of the finished product. Pharmaceutical manufacturers use it as a reference compound and active botanical ingredient.

It is frequently utilized in standardized herbal extracts and nutraceutical capsules. In personal care, it acts as a surface-modifying agent in scalp treatments and conditioning formulations, where it influences film-forming behavior on skin and hair.

As a natural acidulant, it supports pH buffering in botanical-based emulsions requiring mild acid stabilization. This versatile compound is essential for manufacturers seeking high-performance natural additives for complex chemical systems.

Ursolic acid is supplied as a white to off-white crystalline powder. It is available in multiple purity grades, including 25%, 50%, 90%, and 98%+ HPLC-grade specifications, with higher purities targeting pharmaceutical and analytical applications.

Standard packaging ranges from kilogram quantities for formulators to bulk supply for industrial extraction and processing operations. Our material meets rigorous internal quality standards to ensure consistency across every batch delivered to your facility.
