Description
Technical Field
The invention belongs to the field of essence nanocapsules, relates to a lavender fragrance type aromatic nanomaterial, and particularly relates to an essence nanocapsule based on epoxy- β -cyclodextrin and a preparation method thereof.
Background
With the rapid development of economy and the continuous improvement of national living standard, people have more and more diversified demands on flavoring products. Therefore, the use of perfumes in perfumed products is also becoming more and more widespread. The perfuming of the textile endows the textile with more new values and functions such as medical treatment, health care and the like on the basis of meeting the basic requirements and heat preservation of people. However, the components in the essence are generally organic compounds, sensitive to light, heat and oxygen, low in stability, easy to volatilize and difficult to store. The encapsulated essence is applied to textiles, so that the stability of the essence is improved, the release speed of the fragrance in cotton textiles can be controlled, the fragrance retention time of the textiles is greatly prolonged, the textile has certain washability, the textiles have additional value and functional requirements, and the application range of the encapsulated essence is widened.
Epoxy- β -cyclodextrin greatly improves the water solubility of cyclodextrin due to the introduction of epoxy groups, can be quickly dissolved at normal temperature, takes modified β -cyclodextrin modified by epoxy groups as a wall material, and utilizes the covalent action between active groups and cellulose hydroxyl groups to ensure that the textile has longer fragrance retention time after fragrance increasing treatment, better washing resistance and longer fragrance retention time.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a lavender fragrance type aromatic nano material for a cellulose textile and a preparation method thereof, and the essence nano capsule taking epoxy- β -cyclodextrin as a wall material and the preparation method thereof aim to solve the problems of too fast essence release, oxidative deterioration and the like in the prior art.
In order to solve the technical problem, the invention provides an essence nano-capsule based on epoxy- β -cyclodextrin, which is characterized by comprising the following raw material components in percentage by mass:
preferably, the essence is lavender essence which is a water-insoluble liquid essence.
Preferably, the emulsifier is tween-80.
The invention also provides a preparation method of the essence nanocapsule based on the epoxy- β -cyclodextrin, which is characterized by comprising the following steps:
placing epoxy- β -cyclodextrin and deionized water in a reaction kettle, and fully dissolving under the action of an electric stirrer to prepare a water phase I;
step two: injecting an emulsifier into the water phase I, and fully and uniformly mixing under the action of an electric stirrer to obtain a water phase II;
and thirdly, dripping the essence into the water phase II according to the proportion, stirring and fully mixing, and forming an oil-in-water emulsion, namely the essence nano-capsule based on the epoxy- β -cyclodextrin after high-speed shearing.
Preferably, the shearing time in the third step is 10min, and the shearing speed is 10000 rpm.
The principle of the molecular envelope method applied by the invention is that because the solubility of β -cyclodextrin in water at normal temperature is only 1.85%, the modified β -cyclodextrin modified by epoxy groups is greatly improved in water solubility and can be rapidly dissolved at normal temperature, in an aqueous solution, hydrophobic essence molecules push substances to move into a hydrophobic cavity of the cyclodextrin under the action of hydrophobic bonds and molecular thermal motion, when the cyclodextrin and the molecules reach a certain distance, the acting forces of hydrogen bonds, Van der Waals force, Coulomb force and the like act to form an inclusion compound, and the inclusion compound has certain stability.
The method has the beneficial effects that the epoxy group- β -cyclodextrin is taken as a wall material, the lavender fragrance essence is taken as a core material, and a molecular envelope method is adopted to prepare the lavender fragrance essence nanocapsule taking the epoxy group- β -cyclodextrin as a capsule wall, wherein the water phase is the epoxy group- β -cyclodextrin, the emulsifier and the deionized water, the oil phase is the lavender essence, the water phase and the oil phase are mixed and then are subjected to high-speed shearing to form emulsion, and the essence is coated in the emulsion.
