Plant perfume and preparation method thereof

Abstract

The invention relates to the field of perfume production and preparation, and particularly discloses plant perfume and a preparation method thereof. The plant perfume is prepared from the following raw materials in parts by weight: 60 to 70 parts of double-removed ethanol, 10 to 20 parts of deionized water, 4 to 8 parts of fragrance retention agent, 6 to 8 parts of stabilizer, 10 to 15 parts of plant extracting solution and 0.5 to 1 part of antioxidant, wherein the fragrance retention agent is prepared from beta-ethyl phenylacrylate and 9-ethyl octadecenoate, and the ratio of the beta-ethyl phenylacrylate to the 9-ethyl octadecenoate is (1 to 3): (2 to 4). The preparation method comprises the following steps of: step 1, chopping daphne odora, geranium flower, osmanthus fragrans, perilla leaf, origanum vulgare, paulownia flower and ice berry leaf to 30 to 50 meshes to obtain a mixture A; and step 2, putting the mixture A into a supercritical fluid extraction device for extraction, and extracting for 3 to 4h under the conditions that the flow rate of carbon dioxide is 15 to 30kg / h, the pressure intensity is 20 to 30Mpa and the temperature is 60 to 70 DEG C to obtain the plant extracting solution. The plant perfume disclosed by the invention has the advantage of long-lasting fragrance retention; in addition, the preparation method disclosed by the invention has the advantage of simple preparation conditions.

Description

technical field [0001] The application relates to the field of perfume production and preparation, more specifically, it relates to a plant perfume and a preparation method thereof. Background technique [0002] Perfume is a volatile substance, it has a certain fragrance and fragrance, and when the perfume in the air reaches a certain concentration, it can be perceived by people's sense of smell or taste. Perfume is required to be lovable, spiritually pleasant and rich to beautify people's material culture and life. [0003] Perfume is a product in which fragrances are dissolved in ethanol. Sometimes as needed, additives such as trace pigments, antioxidants, bactericides, glycerin, and surfactants can also be added. Different types of perfumes are formulated through aromatization (the technique and art of blending essential oils). [0004] In view of the above-mentioned related technologies, the inventors found that the fragrance in the perfume is easy to volatilize with ...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor found that the fragrance in the perfume is easy to volatilize with ethanol, so the time of action is relatively short, and it is difficult to achieve the effect of long-lasting fragrance, so it is necessary to invent a long-lasting fragrance.
