“With the increased awareness of natural products, more people are asking questions about the difference between essential oils and extracts. Both play an important role in natural wellness products used in everything from aromatherapy to teas, and the right process is essential to get the most out of these natural substances.
The main difference between essential oils and extracts is the process. While both are extracted from different parts of the plant, the process is very different. Essential oils must be extracted through distillation, while extracts are steeped in a liquid to isolate the flavor.
Oils collected from the aromatic parts of flowers, roots, and leaves are known as essential oils. These oils are concentrated in nature and prepared by steam distillation. The plant parts are placed inside a steam chamber, steam is released over the plant parts, and the oils are collected by squeezing under steam pressure. The extracted substances are collected in the vapor chamber and cooled in a condenser. The condenser creates water and separates the oil into a concentrated form.
With extracts, the plants go through a steeping process, where the collected substance is concentrated. This can also be done by pulverizing the plant. The most common extraction process is herbal tea, while tinctures require the plant material to be steeped in alcohol for a long time to remove the essential compounds.
Each method removes the most important compounds from plants and concentrates the best of nature into a simple, easy-to-use substance.”
My question to Nuqo Trading:
In my handmade soap production1, I use olive oil, which has been infused with 720 grams of herbs such as rosemary, oregano, sage, lavender, in 15 liters of olive oil. The infusion time is half a year. Then the soaked herbs are filtered out, and powdered in the food processor, filtered again and returned to the added oil, so that everything that is possible to extract from the soaked herbs is retained and used in the soap production. The infused olive oil looks black when the grinding and back-filtration are done. The smell is extraordinary. Next to that, I use a tea from the same herbal extract (for many days), which is also very dark. I use this tea to create a lye with sodium hydroxide. Later, when the liquid starts to saponify, I add the necessary amount of essential oil of the same herb for that batch.
My question is: is the result of infusion, and the way I make the oil, also a kind of extract?

Most likely! Your soaps sound amazing!
In the video you can follow the creation of (in this case) lavender soap, from lavender fields to infusion, to cutting and packaging:
