Description

Moisturizing and beautifying essential oil water and preparation method and application thereof

Technical Field

The invention belongs to the field of essence and spice, and relates to moisturizing and beautifying essential oil water as well as a preparation method and application thereof.

Background

The plant essential oil is volatile aromatic substance extracted from flower, leaf, stem, root or fruit of plant by steam distillation, extrusion, cold soaking or solvent extraction. Plant essential oils are composed of a few very small molecules which are very soluble in alcohol/emulsifiers, especially fats, which make them very permeable to the skin and enter the body by mixing with fatty fibers. When these highly mobile substances are volatilized, they are also absorbed by tens of thousands of cells simultaneously, enter the body from the nasal respiratory tract, send messages directly to the brain, control emotions against the operation of the cerebellar system, and control other major functions of the body, so that essential oils can enhance physiological and psychological functions in aromatherapy. Each plant essential oil has a chemical structure to determine its flavor, color, fluidity and its mode of operation with the system, and each plant essential oil has a specific set of functional characteristics.

The plant essential oil contains abundant vitamins A, B, C, E, K, and has effects of improving endocrine disturbance, coordinating female physiological problems, promoting blood circulation, regulating menstruation, preventing wrinkle, preventing frostbite, and caring skin. At present, the essential oil beauty water on the market is prepared by a complicated process, is generally prepared by fresh plant flowers, or needs to be cleaned to remove impurities and other complicated processes, or needs to add excessive chemical components such as alcohol pigment and the like, and is harmful and useless to human bodies.
