Problems solved by technology

Generally, the working temperature of the deodorization tower is as high as 200-280°C, and the deodorization process causes a huge loss of nutrients in the oil, such as vitamin E and phytosterols.

Embodiment 1

[0028] The unsaturated fatty acid content of camellia oil is as high as 90%. Camellia oil has a strong permeability to the skin and is a good raw material oil for cosmetics. The following is an example of refining camellia oil.

[0029]Fresh Camellia oleifera seeds are selected as raw materials, and high-quality crude camellia oil is obtained through cold pressing process, and the crude camellia oil is degummed to obtain degummed oil. Then heat up the degummed oil to about 70-75°C, and evenly add sodium hydroxide solution with a mass concentration of 8-12% to the oil at a stirring speed of about 80-100 rpm (just add according to the calculated theoretical alkali amount) That’s it), after stirring for about 15-20 minutes, reduce the stirring speed to 20-30 rpm and continue stirring for about 15-20 minutes to stop stirring. Keep the temperature at about 60-65°C for 6-10 hours to remove the soapstock. Cool the deacidified camellia oil evenly at a rate of 2°C / hour to 4°C to grow ...

Embodiment 2

[0033] Crude corn oil is a kind of darker reddish amber vegetable oil obtained by pressing corn germ. Because the color of crude corn oil is darker, it is best to carry out conventional pre-decolorization in the decolorization process for subsequent further decolorization to colorless Reduce the burden on.

[0034] When heating the crude corn oil to 40°C, add 5% by weight of saturated saline at the same temperature while stirring, continue stirring for 20 minutes, and let it stand for 24 hours to separate the degummed oil. Under normal pressure, add sodium hydroxide with a mass fraction of about 10% to the oil temperature of 45°C for alkali refining and deacidification, and settle for 8 hours to separate the soapstock. After that, wash with water three times to remove the soap in the oil, and then add about 0.5-1% of the decolorizing agent (activated white: soil activated carbon = 3:1) mixture into the oil heated to 75-85°C under vacuum at about -0.095MPa for pretreatment. ...

Embodiment 3

[0037] Sweet almond oil contains more than 90% unsaturated fatty acids such as oleic acid, linoleic acid, etc., and is rich in vitamins A, B1, B2, B6 and E. It is a non-drying oil with low melting point and freezing point, easy to emulsify. It is one of the most widely used base oils in aromatherapy massage. Sweet almond oil is very mild and has good skin-friendly properties, suitable for itchy, red, dry and pimples. The texture is light and soft, moisturizing and not greasy. It can be blended with any vegetable oil, and it also has the effect of isolating ultraviolet rays. my country is rich in sweet almond resources, and the exchange rate earned by export ranks first in the country's native products. Therefore, the production of high-quality sweet almond oil is of great significance to the transformation of my country's rich almond resources and the development of the cosmetics industry.

[0038] The sweet almond crude oil that needs to be refined is degummed-alkali-refi...

Abstract

The invention relates to a production method for high-quality cosmetic oil. The plant oil comprises, but not limited to, tea oil, corn oil, wheat germ oil, rice bran oil, olive oil, sweet almond oil, sunflower seed oil, grape seed oil, avocado oil, evening primrose oil, mixed plant oil, etc. The production method comprises the following steps: subjecting crude oil to degumming, deacidification, drying, winterization and the like, then slowly adding the obtained oil into a filled dry silica gel column, and allowing the plant oil to be decolorized, deodorized and further deacidified in the process of column chromatography so as to be able to obtain colorless, odorless, clear and transparent plant oil. According to the invention, a dry silica gel column is used for further decolorization and deodorization, and no organic solvent is used, so great loss of nutrient components due to high-temperature vacuum decolorization and deodorization in a traditional process is avoided, and the obtained product is significantly applicable to requirements of the high-quality cosmetic oil. The production method provided by the invention is applicable to large-scale production, and conventional oil processing enterprises can utilize existed production equipment, so less investment is newly increased.

Description

technical field [0001] The invention belongs to the field of oleochemical industry, and relates to a method for refining vegetable oil, in particular to a method for producing high-quality cosmetic oil. Background technique [0002] Oil is one of the basic raw materials commonly used in cosmetics. High-grade cosmetic oils usually require high content of unsaturated fatty acids, strong permeability to skin or hair, easy absorption by skin or hair, good anti-oxidation, not easy to rancidity, non-toxic, and skin-friendly No irritation or allergies, crystal clear appearance, colorless and odorless. [0003] In general, both edible oils and cosmetic oils need to be refined, which is to improve the appearance, taste and stability of the product. In addition, the refining process can also remove some harmful substances. At present, the refining method of domestic cosmetic oil is basically the same as that of edible oil. However, there are some differences in the requirements for ...
