Problems solved by technology

Although relatively pure camellia oil can be obtained, its cost is too high; secondly, most of the substances beneficial to the skin originally contained in camellia oil are removed, so that the beneficial ingredients of camellia oil are lost

Embodiment 1

[0014] (1) Choose 100 kg of fresh and mildew-free high-quality Camellia oleifera seeds, minimize the harmful substances brought in due to quality problems of Camellia oleifera seeds, such as aflatoxin or other impurities, and dry them at a vacuum degree of -0.093MPa and a temperature of 95°C until the water content is 6%; after natural cooling, peel off the shell and remove the camellia seed shell, so that the shell content of the camellia seed kernel is less than 5%; press at room temperature to obtain 20 kg, light yellow color with an acid value of 2.5 mgKOH / g High-quality camellia oil, the light yellow camellia oil refers to Lovibond color value 25.4mm slot: the red is lower than 3.5, the yellow is lower than 35; the camellia seed is dried in vacuum at a lower temperature, cooled naturally, Peeling and pressing at room temperature without crushing, softening, and flaking, not only simplifies the pre-treatment process, but also avoids the scorching that may be caused during t...

Embodiment 2

[0024]Select 100kg of fresh and mildew-free high-quality camellia oleifera seeds, and dry them at a vacuum degree of -0.097MPa and a temperature of 105°C until the moisture content is 4%; after natural cooling, peel off the shells and remove the shells of the tea seeds so that the tea seeds contain shells The amount is less than 5%; press at normal temperature to obtain 25 kilograms of high-quality crude camellia oil with an acid value of 1.5 mgKOH / g and a light yellow color; heat 100 liters of light yellow crude camellia oil with an acid value of 1.5 mgKOH / g to 70 ° C, Filter or centrifuge to remove impurities, so that the impurity content of the crude camellia oil is less than 0.2%; when the temperature of the crude camellia oil is 40°C, add 1.5 liters of 8% sodium hydroxide solution within 15 minutes, and stir at 60 rpm for 25 minutes, Then stir at 30 rpm for 20 minutes, while raising the temperature of the camellia oil to 68°C, let it stand for 8 hours, remove the soapstock...

Abstract

The invention relates to a preparation method of cosmetics camellia oil. High-quality camellia seeds are selected to be used as the raw material; the camellia seeds are roasted under the negative pressure and at the lower temperature, and are husked after natural cooling and are squeezed at the room temperature to obtain high-quality crude oil with low acid value and pale yellow color; impurities are removed through filtration under the heating condition, alkali refining and ethanolic extracting two-stage process is utilized for acid stripping and de-coating; then the mixture composed of active carbon and floridin is used as de-coloring agent for de-pigmentation; peroxide and unclean flavor are removed through deodorization; then the drying winterization is acted; finally, the cosmetics camellia oil is obtained, wherein, the acid value is less than 0.1 mgKOH / g, the peroxide value is less than 0.5 mmol / kg, the appearance is colourless approximately as well as clear and translucent, and no unclean flavor exists. The cosmetics camellia oil reaches or exceeds the requirement of the national standard GB11765-2003 on first level expressed tea-seed oil, and can be directly used for manufacturing the cosmetic such as skin care oil for babies; in addition, an edible camellia oil fabrication plant can be improved for production, thereby lowering the investment cost greatly.

Description

technical field [0001] The invention belongs to the field of oleochemical industry, and relates to a method for preparing camellia oil which can be used as base oil for skin care cosmetics, in particular to a method for preparing cosmetic base oil by using camellia seeds as raw materials. Background technique [0002] Oil is one of the raw materials commonly used in cosmetics, also known as cosmetic base oil, and its main component is fatty acid glycerides. Advanced cosmetic base oils usually require high content of unsaturated fatty acids, strong skin permeability, easy absorption by the skin, good oxidation resistance, non-toxic, irritating or sensitizing substances to the skin, crystal clear appearance, colorless and odorless. [0003] Camellia oleifera is one of the four major woody edible oil species in the world. Camellia oil, also known as tea seed oil or tea tree oil, has an unsaturated fatty acid content of more than 85%, which is similar to the famous cosmetic base...
