Description

Oil of Pennyroyal is a highly volatile essential oil derived from the *Mentha pulegium* plant, valued for its characteristic minty and herbaceous aroma. This natural extract is a key ingredient for formulators seeking authentic botanical profiles and specific functional properties. It serves as a critical raw material for manufacturers in the fragrance, flavor, and botanical product industries, where consistent quality and reliable supply are paramount.

Application

• Fragrance & Perfumery: Used as a middle note in fine fragrances, soaps, detergents, and personal care products for its fresh, minty-pungent character.
• Flavoring Agent: Employed in trace amounts to impart a sharp, mint-like flavor to certain food products, confectionery, and oral care items like mouthwash and toothpaste.
• Aromatherapy & Wellness: Incorporated into diffuser blends, massage oils, and topical preparations within the natural products sector for its traditional aromatic properties.
• Botanical Extracts & Natural Products: Serves as a base material for the production of standardized herbal extracts, tinctures, and supplements.
• Research & Development: Utilized in analytical laboratories as a reference standard and in R&D for studying the properties of pulegone and other monoterpenes.
• Industrial Applications: Historically used as a flavoring in certain tobacco products and as a starting material for the synthesis of other aroma chemicals.

Quality Control

Our Oil of Pennyroyal is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and authenticity. Quality is verified through a series of analytical tests including organoleptic evaluation, specific gravity, refractive index, optical rotation, and chromatographic profiling (GC/MS) to confirm the characteristic composition, including the presence of key components like pulegone. A Certificate of Analysis (COA) detailing these parameters is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
