Essential oil products mainly involve concepts such as essential oils, carrier oils, and hydrosols. It's important to note that there are currently no strict national standards to distinguish between these concepts; differentiation relies more on marketing and public awareness.
Single essential oils refer to 100% pure plant essential oils, usually named after the plant (e.g., rose oil, lavender oil, camellia oil). Due to their high purity, they are not suitable for direct application to the skin, as this can easily burden the skin, causing allergies or even burns. Before use, the carrier oil and single essential oil should be mixed and diluted according to the instructions before applying directly to the skin using massage or other methods.
Compound essential oils are blends of various plant essential oils based on their different properties. Generally, their active ingredient content is around 3%, while the remaining main component is a carrier oil used for blending. Consumers can apply compound essential oils directly to the skin on the face, arms, legs, etc., according to the product instructions.
Carrier oils, also called base oils or blending oils, are non-volatile oils obtained from the seeds and fruits of various plants through pressing and extraction. They are plant-based medium oils used to blend one or more high-concentration single essential oils. They are mild in nature and easily absorbed by the body, and can also be used alone as skin care oils or massage oils.
Hydrosols, also known as water-based essential oils, are 100% saturated distillates separated during the distillation and extraction of essential oils. In addition to containing small amounts of essential oil components, they also contain water-soluble substances from the plant. Compared to essential oils, hydrosols have a lower concentration and are more easily absorbed by the skin.
