Pulegone dosage

Pulegone is an aromatic monoterpene naturally present in certain mint species, notably pennyroyal (Mentha pulegium) and spearmint (Mentha spicata). Known for its powerful and refreshing aromas, it is widely used in the cosmetics and fragrance industries. However, its toxicity at high doses makes it a closely monitored molecule, particularly in food and cosmetic products.

Pulegone testing ensures regulatory compliance of products and guarantees safe use. This analysis is essential for manufacturers of essential oils, perfumes, food supplements, and cosmetics who wish to highlight the quality and transparency of their formulations.

Analytical methods

Pulegone control is generally performed by gas chromatography, with two main approaches:

• GC-FID (gas chromatography with flame ionization detection) , allowing robust and reproducible quantification.
• GC-MS (gas chromatography coupled with mass spectrometry) , which offers precise and sensitive identification, even at trace levels, in complex matrices.

These techniques are suitable for essential oils and aromatic formulations, where pulegone can coexist with other monoterpenes such as menthol, piperitone or menthofuran.

Matrices involved

Pulegone measurement is particularly relevant in the following samples:

• Essential oils of mint, pennyroyal and other aromatic plants.
• Cosmetic products such as creams, balms, lotions and perfumed skincare products.
• Food perfumes and flavorings , particularly in chewing gums, confectionery and flavored drinks.
• Plant extracts used in nutraceuticals and phytotherapy.

Industrial and regulatory applications

Analytical control of pulegone addresses several industrial and scientific needs:

• Regulatory compliance : the pulegone content is strictly regulated by health authorities, particularly in the European Union, where maximum thresholds are set for food and cosmetics.
• Consumer safety : avoid the risks of hepatotoxicity or neurotoxicity associated with excessive consumption.
• Standardization of extracts : ensuring a consistent and controlled composition of essential oils and aromatic products.
• Adding value to finished products : highlighting traceability and analytical quality as a selling point.
