Problems solved by technology

[0015] The most widely used film-forming material abroad is high-molecular-weight α-cyanoacrylate, which can be bonded with a single component without solvents, but has disadvantages such as too fast reaction speed, poor water resistance, and high brittleness.
Nitrocellulose and polyvinyl alcohol are widely used in China, which can be used as medical film-forming materials, with good water resistance but poor adhesion

Embodiment 1

[0034] Embodiment one: a kind of preparation method of lavender essential oil liposome liquid band-aid, comprises the following steps:

[0035] 1). Using supercritical CO 2 Extraction of lavender and / or lavender flowers by fluid extraction to obtain lavender essential oil;

[0036] 2). Use refrigerated centrifugation, rectification, molecular distillation and / or adsorption technology to remove impurities in step 1);

[0037] 3). Using phase balance technology to optimize the supercritical carbon dioxide extraction of essential oils in step 2);

[0038] 4). The lavender essential oil obtained in step 3) was prepared into lavender essential oil liposomes by supercritical anti-solvent method.

[0039] A lavender essential oil liposome liquid band-aid, which comprises the lavender essential oil liposome obtained by the above preparation method.

[0040] As a further solution of the present invention: the band-aid carrier is film-forming plastic, solvent and / or plasticizer.

Embodiment 2

[0041] Embodiment 2: The difference between this embodiment and the previous embodiment lies in: Step 2) Impurities are removed by refrigerated centrifugation.

[0042] Specific instructions:

[0043] 1.1 Preparation of lavender essential oil

[0044] 1.1.1 Extraction by supercritical CO2 fluid extraction

[0045] The factors affecting the yield and composition of lavender essential oil were studied, and the extraction pressure, temperature, time and CO2 flow rate were selected as the investigation factors to determine the key process conditions to increase the yield of essential oil and reduce the content of impurities, and optimize the process parameters.

[0046] 1.1.2 Use refrigerated centrifugation, rectification, molecular distillation and adsorption to remove unfavorable components

[0047] Research on the removal technology of fatty acids, terpenes and photosensitive components impurities in lavender essential oil, and the enrichment technology of alcohol esters;

Abstract

The invention discloses a preparation method of a lavender essential oil lipidosome liquid band-aid and belongs to the field of band-aids. The preparation method comprises the following steps that 1,a supercritical CO2 fluid extraction method is adopted to extract lavender essential oil from lavenders and / or lavender flowers; 2, refrigerated centrifugation, rectification, molecular distillation and / or adsorption techniques are adopted to remove impurities in the step 1; 3, a phase balance technique is adopted to optimize supercritical CO2 extraction of the essential oil in the step 2; 4, a supercritical anti-solvent method is adopted to prepare lavender essential oil lipidosome with the obtain lavender essential oil. Compared with the prior art, the preparation method has the advantages that cytothesis can be promoted, wound healing can be promoted and oily and pimple skin can astringe by utilizing lavenders, a treatment effect on scar fading is played, lavenders are prepared into thesprayable band-aid, and the lavender essential oil lipidosome liquid band-aid is quick and convenient to use and firm in fitting while the above effect is ensured. In addition, the symptoms of skin diseases such as psoriasis, dermatitis and eczema can also be relieved.

Description

technical field [0001] The invention relates to a band-aid, in particular to a lavender essential oil liposome liquid band-aid and a preparation method thereof. Background technique [0002] Lavender is a precious and important natural spice plant, its fragrance is refreshing, rich and pleasant. After ten years of careful cultivation by Yili people in Xinjiang, lavender has formed a scale on the banks of the Yili River at the foot of Tianshan Mountain. The cultivation area has reached more than 30,000 mu, accounting for more than 95% of the national lavender planting area. It is comparable to Provence in France and Furano in Hokkaido, Japan Known as the world's three major lavender bases. At present, the Xinjiang Ili Kazakh Autonomous Prefecture in the hinterland of the Tianshan Mountains has become the main base for planting and processing lavender in China, as well as the largest spice production base in Asia. Xinjiang lavender oil has a huge output and excellent quality...
