Uncovering the Secrets of Citrus Products

Researchers at the University of Messina in Italy have made a groundbreaking discovery in the world of cosmetics! They have perfected a method that utilizes deep eutectic solvents (DES) to extract oxygen heterocyclic compounds (OHCs) from citrus-scented creams. This pioneering study marks the first time DESs have been employed for this purpose in cosmetic samples.

Quick and Effective Extraction Process

The team achieved an incredible feat using high-performance liquid chromatography–photo diode array (HPLC–PDA), successfully separating and quantifying a staggering 35 OHCs—including nine coumarins, nineteen furocoumarins, and seven polymethoxyflavones—in under ten minutes!

Health Risks in Your Favorite Creams?

However, not all the findings boast good news. Out of seven cream samples analyzed, two exceeded the acceptable levels of furocoumarins. Alarmingly, one product failed to disclose ‘perfume’ or ‘aroma’ on its label while containing high levels of coumarins, raising serious health concerns.

The Importance of Regulatory Oversight

Researchers emphasize the potential health risks linked to the frequent use of cold-pressed citrus essential oils in cosmetics, calling for stricter regulatory monitoring in the industry. Their goal? To ensure safer products for consumers!

The Science Behind the Scent

Citrus essential oils are cherished not only for their delightful fragrances but also for their therapeutic properties found in creams and lotions. The pleasant aromas stem from volatile fractions, while non-volatile components, the OHCs, play crucial roles in organic chemistry and are essential for quality control.

Innovative Extraction Technology

In this study, DESs made from a combination of chloride and urea were used at a 1:2 molar ratio with 20% water by weight. The complexity of the citrus creams necessitated a solid-phase extraction (SPE) clean-up to ensure a pure extract.

Raising Awareness and Future Research

Through their findings, the researchers aim to alert both producers and consumers about the hidden dangers lurking in commonly used cosmetics. While this research is just a starting point, they plan to test additional DESs and refine extraction techniques to boost recovery values.
