Embodiment 1

[0027] Embodiment 1: tea seed oil processing

[0028] 1. The first step of short-path distillation treatment: 1000g of tea seed oil (Jinhua Jinshan Oil Co., Ltd.) raw material, distillation temperature 160-170°C, operating pressure 0.02mmHg, feed temperature 80°C, speed 150r / min. The obtained components include distilled condensate and residual residual liquid. The residual residual liquid mainly contains triglycerides, some diglycerides, vitamin E, sterols and some heavy molecular substances, and the light components mainly contain fatty acids, solvents, etc. Light molecular substances, analyzed by gas chromatography-mass spectrometry, the purity of fatty acids reaches 98%.

[0029] 2. The second step of short-path distillation treatment: take the residual liquid part of the first short-path distillation as the raw material for this time. The distillation temperature is 200-220°C, the operating pressure is 0.01mmHg, the feed temperature is 80°C, and the rotation speed is 150...

Embodiment 2

[0030] Example 2: skin care oil deployment

[0031] Components are by weight percentage: the tea seed oil (the condensate part of the second distillation) after the second short-path distillation treatment in Example 1: 90%; rose essential oil (Zhejiang Jiujiuhongrose Technology Co., Ltd.) 0.8% ; Esters: 9.2% isopropyl palmitate, the three are mixed and prepared, evenly packaged to obtain the product, and the product has a shelf life of more than 24 months.

[0032] The skin care oil of the present invention is fine and smooth, feels oily, has good spreadability, is easy to absorb, and has a rose smell. Regular use, non-irritating to the skin, nourishes and moisturizes the skin, revealing the smoothness and moisture of the skin.

Embodiment 3

[0033] Example 3: skin care oil deployment

[0034] Components are by weight percentage: the tea seed oil (the condensate part that distills out for the second time) after the second short-path distillation treatment of embodiment 1: 88%; ) 1%; esters: isopropyl myristate 11%, the three are mixed and prepared, and the product is obtained after being evenly packaged, and the product has a shelf life of more than 24 months.

[0035] The skin care oil of the present invention has fine and smooth hand feeling, moisturizing effect and jasmine flavor, makes the skin smooth, tender, white and bright, can resist free radical damage, and prevent skin moisture loss.
