Description

Technical Field

[0001] The present invention belongs to the technical field of essential oil compositions, and particularly relates to a novel essential oil patch with dual functions of anti-wrinkle and sleep aid, and a preparation method and application thereof. Background Art

[0002] Essential oils are highly concentrated volatile aromatic compounds extracted from parts of plants such as flowers, leaves, stems, roots, fruits, and barks through methods such as distillation, cold pressing, and solvent extraction. They not only have unique aromas but also are rich in various bioactive components and are widely used in aromatherapy, skin care products, medicine, food flavoring, and other fields.

[0003] Plant essential oils, also known as volatile oils or aromatic essential oils, are mainly composed of secondary metabolites extracted from the fruits, seeds, skins, rhizomes, or flower leaves of plants. They are a class of natural active substances with aromatic odors and have functions such as promoting growth, anti-inflammatory, antioxidant, anti-parasitic, anti-stress, antibacterial, and immunomodulatory. Plant essential oils contain aromatic compounds that are friendly to the environment and the human body, and due to their diverse biological activities, they are widely used in industries such as food, medicine, cosmetics, and daily chemical products.

[0004] When using existing essential oils, generally the essential oil is placed alone in an essential oil bag with a cotton pad inside. When in use, the essential oil cotton pad is taken out and placed on a leak-proof device, or the essential oil is directly separated from the cotton pad, and the essential oil is dropped on the cotton pad when in use. This makes the essential oil generally directly in liquid contact with the skin, or the essential oil is dropped on the oil-absorbing cotton paper and then contacts the skin, which is completed by the user himself. Generally, there is a large waste during use and the operation is relatively cumbersome, thus requiring the use of essential oil patches. At the same time, there is skin irritation, and redness and allergies will occur after long-term contact with the skin; the essential oil patch has a single function, the essential oil sustained-release effect is poor, the absorption rate through the skin is low, and the effect is relatively short-lived, affecting its actual application effect.

[0016] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: 1. In the essential oil patch formulated by the present invention, essential oil layers with three different component essential oils are respectively provided, and a high absorption effect of the essential oil patch is achieved through sequential progression and mutual synergistic cooperation.

[0017] 2. In the setting of the first essential oil layer, it is mainly used to open the skin cutin layer. Since essential oils are mainly absorbed through the skin, that is, essential oils are absorbed through the skin and capillaries at a certain rate to produce effects. However, the existence of the skin cutin layer will reduce the penetration of essential oils, thus affecting the use effect of essential oils. Therefore, the present invention selects natural penetration enhancers such as peppermint oil, clove volatile oil, angelica volatile oil, eucalyptus oil or semen myristicae oil as the first essential oil layer, which can promote the expansion of the epidermal cell gaps, thereby reducing the blocking effect of the skin on foreign drugs and facilitating the diffusion of drugs through the intercellular spaces of epidermal cells. Moreover, it relies on its extremely strong lipophilicity and penetration ability; through its penetration efficiency, it drives other drugs to penetrate the epidermal cutin layer and penetrate into the subcutaneous tissue.

[0018] 3. In the setting of the second essential oil patch, it is mainly used to express the anti-wrinkle effect. Select plant chemicals with high antioxidant and free radical scavenging activities, such as ylang-ylang essential oil, lemon essential oil, patchouli essential oil, rosemary essential oil, neroli essential oil, jasmine essential oil or rose essential oil; it is used to promote cell renewal and reduce the appearance of wrinkles, keep the aging skin moist, and prevent the formation of wrinkles due to the loss of essential moisture.

[0019] 4. In the setting of the third essential oil patch, it is mainly used to repair the skin barrier and help sleep. By selecting chamomile essential oil, lavender essential oil, bergamot essential oil or sweet orange essential oil, etc., it closes the cutin layer opened in the first step, which can help relieve anxiety and improve sleep while repairing the skin barrier; closing the cutin layer helps to effectively inhibit the volatilization of essential oils and extend the sustained release period of essential oils, so that essential oils can fully play the anti-wrinkle and sleep-aiding effects.

[0020] 5. In each layer of essential oil patch of the present invention, a sustained release material is added to control the volatilization of essential oils, protect the active ingredients, control the release rate, etc., so that essential oils can fully play their effects; at the same time, in order to prevent the penetration of essential oils between layers and affect the use effect, an anti-permeation membrane is used to block between each layer of essential oils; the anti-permeation membrane is made of a temperature-controlled material, which can be self-degraded at normal body temperature without harming the skin, and can stimulate the next layer of essential oil to play its role.
