Description

Natural Air Freshener Comprising Plant Complex Extracts as Active Ingredient and Use thereof

The present invention relates to a natural fragrance composition containing a plant complex extract as an active ingredient and its use, and more particularly, to a cypress ( Chamaecyparis obtusa ) extract, a lavender ( lavandula angustifolia ) extract, a rosemary ( Rosmarinus officinals ) extract, and a peppermint ( Mentha ) piperita ) It relates to a natural fragrance composition containing the extract as an active ingredient.

As the economy develops and living standards improve, the desire for well-being or healing is increasing. Accordingly, in order to improve the quality of life, the demand for products such as air fresheners or diffusers that diffuse a good fragrance in a room is also increasing.

Of these, air fresheners usually have a characteristic that the scent fills the space the moment it is opened and then disappears, and the diffuser has a characteristic that a subtle scent lasts from the beginning to the end.

The fragrance, which is a main component of the fragrance or diffuser, can be divided into natural fragrances and chemically synthesized fragrances. Currently, most fragrance compositions mainly use chemically synthesized fragrances. However, chemical synthetic fragrances do not give a continuous affinity to users, and additives used to last a long time may cause side effects such as allergic reactions, so interest in fragrances using natural essential oils obtained from plants is increasing (Patent Publication No. 10-2020-0091590, Patent Registration No. 10-1834491, etc.).

Natural essential oil and natural hydrosol are used in various ways around the world. In particular, these are the main raw materials for fragrances, and they are used as skins, lotions, cosmetics, lotions, or perfumes in the cosmetic field, as well as aroma therapy and humidifiers. It is widely used as a deodorant, daily necessities, or raw material for food and medicine, so it has great industrial value. Hydrosol has antiseptic and sterilizing effects, regulates the pH of the skin and moisturizes the skin to prevent or reduce skin diseases and allergic reactions. Therefore, hydrosol has become a major raw material for skin, lotion, or skin moisturizer of natural cosmetics, and is becoming an important resource as a raw material for cosmetics.

Moreover, recent consumption trends for fragrances or diffuser products favor products with not only simple fragrance emission but also additional functionality, so research on plant extracts having functionality and excellent fragrance is active.

In addition, most commercially available air fresheners do not have much of a problem to be used in a narrow space, but when used in a large space, diffusion is not good, so fragrance ingredients cannot be vaporized throughout the space. There was a disadvantage that it did not work uniformly.

Accordingly, the present inventors verified the possibility of using natural oil extracts extracted from plants as fragrances or diffuser components, and as a result, oil extracts extracted from four types of plants: cypress, lavender, rosemary, and peppermint were combined to form a fragrance composition. When used, it was confirmed that the fragrance composition is physically and chemically stable, has a very good sensory effect, and exhibits a uniform fragrance effect due to excellent diffusivity even in a large area space, thereby completing the present invention.

Accordingly, the main object of the present invention is to provide a natural fragrance composition containing a complex extract of four types of plants, cypress, lavender, rosemary, and peppermint as an active ingredient.
