Abstract

The preparation process of tea seed oil in cosmetics level includes stoving tea seed, crushing to size of 1-4 mm, supercritical CO2 extraction at 20-35 MPa and 30-50 deg.c for 1-3 hr, constant-temperature pressure-regulating extraction in a separating reactor at pressure of 3-10 MPa and evaporator temperature of -8 to -1 deg.c, eliminating impurity with impurity eliminating agent at 20-50 deg.c, and final filtering. The technological process is also suitable for producing medical tea seed oil. The extracted tea seed oil is color-less and transparent, and the preparation process has high yield, simple operation, no solvent used and no pollution, can maintain the natural characteristic of tea seed oil and is suitable for industrial production.

Description

The preparation method of cosmetics-stage tea oil

Technical field

The invention belongs to chemical field---the manufacture craft of cosmetic material, the particularly preparation method of cosmetics-stage tea oil.

Background technology

The tea oil unsaturated fatty acids account does not contain harmful erucic acid more than 85%, vitamin A and E content height, and storage tolerance easily is absorbed by the body, and can prevent and treat hypertension, cardiovascular disorder, be the outstanding person in the edible vegetable oil.Tea tree is seldom sprayed insecticide, and is real green non-pollution food, welcome by domestic and international market.In Japan, the tea oil price is 7.5 times of rapeseed oil.Industrial, tea oil can be produced oleic acid and ester class thereof, produce soap and Vaseline etc., also can be made into stearic acid and glycerine.Pharmaceutically, tea oil can be used for making injection and the various ointment of modulation, pill etc., and is among the people also with tetter such as tea oil treatment scald and burn and ringworm of the body, chronic eczemas.On the industry of making up, tea oil energy nourishes rough skin absorbs the most deleterious short wave ultraviolet of human body, is made into natural senior beauty and skin care, series of hair protection makeup by refining.It is reported that France, the U.S., Japan are just starting the upsurge of an Oleum camelliae beauty treatment, beauty treatment.Global oil tea mainly is distributed in China Yangtze valley and areas to the south.In addition, have only state-owned a small amount of distributions such as Vietnam, Burma, Thailand, Malaysia and Japan.So oil tea is the advantageous natural resources of China.The tea oil of China is not seen and is produced the oily report of sampling tea of making up based on edible.

Summary of the invention

The purpose of this invention is to provide a kind of preparation method who from the tea seed, extracts cosmetics-stage tea oil.

The present invention realizes by following technical process: will be crushed to diameter 1-4mm after the oven dry of tea seed, when carrying out 30-50 ℃ of extraction of supercritical co (20-35MP) 1-3 again, separating still pressure 3-10MP isothermal pressure regulation extraction, evaporator temperature-1--8 ℃, with cleaner 20-50 ℃ removal of impurities, filtration, promptly obtain product of the present invention.This technology is suitable for medical tea oil production equally.

Supercritical carbon dioxide extraction tea oil adopts extract at room temperature, and it is low to extract pressure, need not come unstuck, operations such as dehydration, high temperature deodorization, chemistry are concise, decolouring.Normal temperature uses neutral sorbent material down, and product does not decompose, and makes product keep the fine quality of pure natural.Tea oil water white transparency, yield height, the method that the present invention extracts simply, do not used any solvent, pollution-free, the pure natural characteristic that can keep tea oil, met the cosmetics quality requirement.The present invention is suitable for suitability for industrialized production, can effectively improve the availability of raw material, further widens the new purposes of tea oil at makeup, field of medicaments, improves value-added content of product and camellia oleiferaindustry economic benefit greatly, increases oil tea base farmers' income.

Description of drawings

Accompanying drawing is a process flow sheet of the present invention.

Specific embodiments

To be crushed to diameter 2-3mm after the oven dry of 1Kg tea seed, carry out 35 ℃ of supercritical cos (25MP) extraction 2 hours again, separating still pressure 6MP extraction, evaporator temperature-4 ℃, with 30 ℃ of removal of impurities of cleaner, filtration, obtain the cosmetics-stage tea oil 102.6g of clear.
