Description

Larrea Mexicana, Ext. is a standardized botanical extract derived from the leaves of the *Larrea tridentata* plant, commonly known as chaparral or creosote bush. This extract is valued for its complex profile of bioactive polyphenolic compounds, primarily nordihydroguaiaretic acid (NDGA), which contribute to its potent antioxidant and preservative properties. It serves as a key functional ingredient for manufacturers in the cosmetic, nutraceutical, and specialty chemical industries seeking natural, multi-functional actives.

Application

• Cosmetic & Personal Care: Utilized as a natural antioxidant and preservative booster in creams, lotions, and serums to enhance shelf-life and protect skin from oxidative stress.
• Dietary Supplements & Nutraceuticals: Incorporated into formulations for its traditional use and antioxidant support, often in capsule or tablet form.
• Functional Food & Beverages: Acts as a natural preservative and stabilizer in products where synthetic additives are to be minimized.
• Industrial Preservatives: Used in natural or "green" preservative systems for coatings, adhesives, and other susceptible materials.
• Research & Development: Serves as a reference standard or starting material for pharmacological and biochemical research into natural product chemistry.
