How to choose single essential oil and compound essential oil?

For a long time, plant essential oils have been widely used in beauty and health care and are well known by people. The most common is aromatherapy, which is an adjuvant therapy that uses plant essential oils to act on the whole body to relieve, prevent or treat certain diseases of the human body.

I believe many people have had personal experience, but does anyone know what kind of essential oil they are using? In other words, are you using a single essential oil or an essential oil combination? Some people will stand up and ask the question 'Isn't essential oil an essential oil?' In fact, it is not. Essential oils have their classifications, grades, and mechanisms of action.

Essential oils can be roughly divided into three categories, namely plant single essential oils, plant compound essential oils and base oils. Single essential oils are generally used when mixing other essential oils and are highly irritating, so they cannot be used directly on the skin and must be diluted before use; compound essential oils refer to formula essential oils that have been prepared and can be used immediately; base oils are often It is used as a diluted oil for unilateral essential oils, with fine texture, high lubricity, mild and safe, and common olive oil, almond oil, sesame oil, etc.


Unilateral essential oils are essential oils extracted from a single plant, with specific efficacy and individual characteristics, and are generally expensive, so they are rarely used in beauty salons, massage parlors and other places. Essential oils are the most commonly used in these places. They can act directly on the skin, because there are also base oils in them, and they can also reduce the discomfort of the skin during massage.

Essential oils are generally classified into 4 grades according to their concentration levels, as follows:

Level 1: Pure essential oils. It is a high concentration essential oil obtained from natural organic plants in pure medical grade quality.

The second level: food grade. Contains synthetic materials, such as chemical agents, synthetic agents or vehicle oils, base oils, and can be used as food additives, such as flavoring, preservatives, etc.

Level 3: Perfume level. Often mixed with chemical solvents, the concentration can also be divided into 5 grades: more than 20% (essence concentration), 10%-20% (perfume concentration), 5%-12% (Eau de Toilette concentration), 3%-6 % (cologne concentration) and 1%-2% (clear perfume concentration).

Level 4: Fragrances, Hydrosol or Flower Water. Refers to a 100% saturated distilled stock solution that is separated during the extraction process of essential oils.
