Oleanolic acid

Oleanolic acid (CAS 508-02-1), also known as Oleanic acid, is a pentacyclic triterpenoid derived from plant sources including olive pomace, cloves, and various medicinal herbs.

In industry, it functions as a bioactive intermediate and stabilizing agent across pharmaceutical synthesis and cosmetic formulation. In pharmaceutical manufacturing, it serves as a key starting material.

It is used for the semi-synthesis of more complex triterpenoid derivatives and active pharmaceutical ingredients targeting metabolic and hepatoprotective pathways. Cosmetic formulators incorporate it into anti-aging creams.

Serums and scalp treatments utilize its antioxidant activity to support product stability and position the formulation for premium positioning. In oral care products, it is used as a functional ingredient.

It is found in toothpastes and mouthwashes targeting gum health. Flavor and fragrance applications also draw on its plant-derived profile as a minor acidulant and fixative component in certain botanical extracts.

Oleanolic acid is supplied as a white to off-white crystalline powder. Standard commercial grades include technical grade for industrial synthesis and high-purity grades for pharmaceutical and cosmetic applications.

Material sourced from olive or plant extraction is available with documentation supporting natural origin claims. High-purity grades are typically verified at levels of 98 percent or higher by HPLC analysis.
