Your Guide to Essential Oils

Essential oils date back thousands of years to ancient civilisations. Egyptians used oils in mummification and perfumery, while Greeks and Romans used them in cosmetics, medicine, and religious rituals. Nowadays, in the 21st century, the global essential oils market is booming. Valued at $12.74 billion in 2024, it is projected to grow at a CAGR of 10.69% by 2032 to reach $27.82 billion, driven by the rising consumer demand for natural products, sensory-related aspects and food preservation. (Fortune Business Insights). This rise reflects a broader desire for natural alternatives over synthetic ingredients, emphasising the importance of understanding and incorporating essential oils into a range of product formulations.

What are essential oils?

Essential oils are natural, aromatic substances taken from plants. They contain the plant’s unique scent and flavour, hence the name ‘essential’. Each oil contains a complex chemical profile that provides functional benefits and properties, as well as fragrance enhancement.

How are essential oils produced?

The production of essential oils can vary depending on the source, however, here are some of the most popular methods of production:

Steam Distillation

The most common method, where plant material is steamed, and the essential oil is separated from the condensed water.

Cold Pressing

Used mainly for citrus oils, this involves mechanically pressing the peels to extract the oil without the use of heat or chemicals.

Solvent Extraction

Often used for delicate flowers such as jasmine, this method uses solvents to dissolve and separate the oil.

CO2 Extraction

A modern technique that uses pressurised carbon dioxide to extract high-quality oils without heat.
