Embodiment 1

[0017] The supercritical CO 2 The preparation method of extracting rose fragrance for cosmetics is characterized in that: using rosebuds with a water content of 12.0%, crushing them into a raw material powder with a particle diameter of 80 meshes, and using emu oil with a weight of 0.2% of the raw material powder as an entrainer and raw material powder Mix evenly, and then send the mixture into the supercritical extraction kettle, and input CO into the supercritical extraction kettle 2 The fluid is extracted at an extraction pressure of 35MPa and an extraction temperature of 70°C for an extraction time of 0.5 hours, and then the CO containing the dissolved components of the raw material powder in the supercritical extraction kettle 2 The fluid is introduced into the supercritical separation tank, and the CO 2 Separation, separation time is 0.5 hours, separation to remove CO 2 After that is the prepared rose extract for cosmetics.

Embodiment 2

[0019] The supercritical CO 2 The preparation method for extracting rose fragrance for cosmetics is characterized in that: using rose buds with a water content of 6.0%, crushing it into a raw material powder with a particle diameter of 10 meshes, using emu oil with 20% weight of the raw powder as an entraining agent and the raw material powder Mix evenly, and then send the mixture into the supercritical extraction kettle, and input CO into the supercritical extraction kettle 2 The fluid is extracted at an extraction pressure of 15MPa and an extraction temperature of 25°C for 5 hours, and then the CO containing the dissolved components of the raw material powder in the supercritical extraction kettle is extracted 2 The fluid is introduced into the supercritical separation tank, and the CO 2 Separation, separation time is 0.5 hours, separation to remove CO 2 After that is the prepared rose extract for cosmetics.

Embodiment 3

[0021] The supercritical CO 2 The preparation method for extracting rose fragrance for cosmetics is characterized in that: using rose buds with a water content of 8.0%, crushing it into a raw material powder with a particle diameter of 45 meshes, and using emu oil with a weight of 5% of the raw material powder as an entraining agent and raw material powder Mix evenly, and then send the mixture into the supercritical extraction kettle, and input CO into the supercritical extraction kettle 2 The fluid is extracted at an extraction pressure of 25MPa and an extraction temperature of 40°C for an extraction time of 2 hours, and then the CO containing the dissolved components of the raw material powder in the supercritical extraction kettle 2 The fluid is introduced into the supercritical separation tank, and the CO 2 Separation, separation time is 2 hours, separation to remove CO 2 After that is the prepared rose extract for cosmetics.

Abstract

The invention discloses a method for preparing a rose extract for supercritical CO2 extraction cosmetics. The method aims to overcome shortcomings that in the prior art, solubility is limited, extraction yield cannot be improved, a proper cosolvent is unavailable, and extracts do not have other beneficial effects. The technical scheme mainly includes that the method is characterized by including crushing rose buds with moisture content lower than 12.0% into raw material powder with the particle size ranging from 10 meshes to 80 meshes; adopting emu oil as a cosolvent to be uniformly mixed with the raw material powder; feeding mixture into a supercritical extraction kettle; filling CO2 fluid into the supercritical extraction kettle; realizing extraction under the extraction pressure ranging from 15MPa to 35MPa and at the extraction temperature ranging from 25 DEG C to 70 DEG C for 0.5 to 5 hours; guiding CO2 fluid containing dissolved ingredients of the raw material powder in the supercritical extraction kettle in to a supercritical separation kettle; separating the CO2 from the dissolved ingredients under the separation pressure ranging from 5MPa to 10MPa at the separation temperature ranging from 30 DEG C to 70 DEG C for 0.5 to 5 hours; and obtaining the prepared rose extract for the cosmetics after the CO2 is separated and removed. The weight of the emu oil accounts for 0.2-20% of that of the raw material powder.

Description

technical field [0001] The invention relates to a method for extracting effective components of roses, in particular to a supercritical CO 2 A preparation method for extracting rose extract for cosmetics. Applicable to cosmetics added to creams, creams, milks, and liquids (except perfume). Background technique [0002] The current rose extract is mainly essence, which is an important raw material for making cosmetics in the world. Traditional rose essence is obtained by distilling rose flowers with water. About 4,000 kilograms of rose petals can only be harvested for one kilogram of essence. Very low, so how to improve the yield of rose essence has become the subject of industry research and the goal of efforts. [0003] In order to effectively prevent the oxidation and dissipation of heat-sensitive substances in roses, the extract has no residual solvents to achieve pure natural, non-toxic and harmless to the human body, no pollution to the environment, and improve the yi...
