Description
P664/NLpd PLANT SQUALENE COMPOSITION, PREPARATION METHOD AND APPLICATION THEREOF, AND PRODUCT USING THE SAME
TECHNICAL FIELD The present disclosure relates to the field of preparation of cosmetic raw materials, and in particular to a plant squalene com- position, a preparation method and application thereof, and a product using the same.
BACKGROUND ART Squalene is a highly unsaturated hydrocarbon compound. The chemical name of squalene is 2,6,10,15,19, 23-hexamethyl- 2,6,10,14,18,22-tetracosahexaenoic acid which has a molecular for- mula of C30H50 and belongs to terpenoids. Squalene is widely dis- tributed in animals and plants. In view of its special chemical structure, squalene has many functions such as resisting oxida- tion, promoting skin health and cardiovascular health, assisting in the prevention and treatment of tumors, and improving the human body's ability to withstand hypoxia, and is widely used in the fields of medicine and cosmetics. The application of the squalene in the field of health products has gradually expanded in recent years. Squalene has excellent phytochemical properties, is highly compatible with skin, has softening and moisturizing properties, and is thus widely used in cosmetic formulations.
The squalene on the market is mainly extracted from liver oil of deep-sea sharks. At present, the number of deep-sea sharks is gradually decreasing, and some species are on the verge of extinc- tion, making this source increasingly scarce. Therefore, it is very important to find new squalene resources and develop corre- sponding extraction methods. There have been many reports on the discovery of squalene resources in recent years. In particular, deodorized distillates of vegetable oils are most widely extract- ed. The deodorized distillates are by-products in the process of oil deodorization and are good sources of plant squalene. However, the independent extraction of squalene from the deodorized distil-
lates of vegetable oils alone still has many defects.

DETAILED DESCRIPTION The embodiments of the present disclosure will be described in detail below in conjunction with examples, but those skilled in 5 the art will understand that the following examples are only used to illustrate the present disclosure and should not be regarded as limiting the scope of the present disclosure. If specific condi- tions are not indicated in the examples, these examples shall be carried out in accordance with conventional conditions or condi- tions recommended by manufacturers.
At present, since deodorized distillates are relatively low in squalene content and are mainly used to extract natural vitamin E and plant sterols with higher added value, it is economically unreasonable to extract squalene from deodorized distillates of vegetable oils alone. Therefore, the current researches focus on using by-products of natural vitamin E and plant sterols as raw materials to extract squalene, using low-content natural vitamin E as a raw material to extract squalene, natural vitamin E and some plant sterols at the same time, and using deodorized distillates of vegetable oils as raw materials directly to extract squalene in a few cases. The current process for preparing plant squalene needs to make use of the technologies such as saponification ex- traction, cold precipitation and crystallization, silica gel chro- matography, multi-stage molecular distillation, ion exchange chro- matography, rectification, solvent extraction, activated carbon adsorption and high-speed countercurrent chromatography. The raw materials of squalene extracted and prepared by the above methods are diverse, and the extraction methods are different, resulting in poor versatility and relatively narrow scope of application.
In order to solve one of the technical problems in the prior art, the present disclosure provides a preparation method of a plant squalene composition. The plant squalene method comprises the following steps: introducing raw materials rich in plant squa- lene into a falling-film evaporator continuously and cyclically and performing evaporation treatment, enabling the obtained steam to enter a rectifying tower to be separated, and then recycling a light component to obtain the plant squalene composition contain-
ing plant squalene.
Optionally, the process conditions of the falling-film evaporator comprises: a system pressure of 10-1000Pa and a temperature of 160-260°C.
Optionally, fatty acid and/or fat- ty acid methyl ester are/is collected in the case that the temper- ature of the falling-film evaporator is 160-220°C and the tempera- ture is then risen to 220-260°C, and the plant squalene composi- tion containing plant squalene is collected.
Raw materials rich in plant squalene are introduced into the stable falling-film evaporator having a specific pressure continu- ously and cyclically.
The obtained steam enters the rectifying tower to be separated.
The fatty acid and/or fatty acid methyl es- ter are/is collected in the case that the temperature of the fall- ing-film evaporator is 160-220°C and the temperature is then risen to 220-260°C.
The plant squalene composition containing plant squalene is collected.
In addition to the main component, i.e., the plant squalene, the plant squalene composition may also fur- ther a small amount of natural vitamin E, plant sterols and plant wax.
This method is not limited by the types and ingredients of raw materials, has simple process flow, low cost and relatively stable ingredients, and can realize the preparation of the plant squalene composition through the first-stage rectification.
The prepared plant squalene composition has good safety.
In addition to plant sgualene, the plant squalene composition also contains effective active substances such as natural vitamin E and plant sterols, and can be used for the preparation of cosmetics after simple refining This method is suitable for the preparation of the plant squalene composition used in the production of cosmetics on a large scale.

The raw materials rich in plant squalene are more conducive to the extraction and prepara- tion of the plant squalene composition.
The content of the plant squalene in raw materials rich in plant squalene is typically but not limited to 52, 10%, 153, 20%, 25% or 30%; the content of the natural vitamin E is typically but not limited to 1%, 5%, 10%, 15%, 20%, 25% or 30%; and the content of the plant sterols is typ- ically but not limited to 1%, 5% or 10%.

When the deodorized distillates of vegetable oils are directly used as the raw materi- al, the light component obtained when the temperature of the fall- ing-film evaporator is 160-220°C is mainly fatty acid.
Alternatively, the raw material rich in plant squalene may be a by-product of one or a mixture of two or more of the deodorized distillates of vegetable oils from which natural vitamin E and/or plant sterols are extracted.

As can be seen from the above Examples 1-14, no matter what source the raw material is rich in plant squalene, the preparation method provided in the present disclosure can effectively extract the plant squalene composition. The plant squalene composition meets the raw material requirements for cosmetic preparation. In addition, the method is simple and easy to operate, low in cost, wide in raw material sources, and high in versatility, and can be widely promoted and applied. However, although the preparation method of the plant squalene composition provided by Comparative Examples 1-6 of the present disclosure includes the step of intro- ducing the raw materials rich in plant squalene into the falling- film evaporator continuously and cyclically for evaporation treat- ment, enabling the obtained steam to enter the rectifying tower to be separated and collecting the light component, all conditions used in this method are not within the scope defined in the pre- sent disclosure, and it can be seen from the results that the plant squalene composition cannot be effectively extracted.

The plant squalene composition in Comparative Examples 1-3 are subjected to winterization, decolorization and deodorization refining processes.
Comparative Examples 10-12 This Comparative Example provides a moisturizer, which in- cludes 15% of the plant squalene composition in Comparative Exam- ples 4-6, 2% of emulsifier, and the balance of water, respective- ly.
The plant squalene composition in Comparative Examples 4-6 are subjected to winterization, decolorization and deodorization refining processes.
Experimental example In order to verify the effects of the plant squalene composi- tions prepared by the preparation methods of the plant squalene composition provided in the present disclosure as the cosmetics, 65 female volunteers are invited and randomly divided into 13 groups to evaluate their moisturizing properties of the cosmetics provided in Examples 15-21 and Comparative Examples 7-12, to be specific: The lip balms provided in Examples 15-17, 21 and Comparative Examples 7-9 are applied to the lips respectively, and the moist- urizers provided in Examples 18-20 and Comparative Examples 10-12 are applied to the whole faces. After 6 hours, the skin is tested for the water content with a skin moisture tester. The results are shown in the following table: Group Average water content | Average water content after before use (%) 6 hours of use (%) Example 1 Example 1 Example 17 Example 13 Example 19 Example 2 229 Example 2 228 Comparative Example 7 Comparative Example § Comparative Example 9 Comparative Example 10 Comparative Example 11 Comparative Example 12 239 It can be seen from the above table that the lip balms and the moisturizers provided in Examples 15-20 of the present disclo- sure have good moisturizing effects and improve the skin's mois- ture retention function.
Natural vitamin E, plant sterols and oth- er active substances make the lip balms and the moisturizers have repairing, soothing, calming and skin care effects, and suitable for users of all skin types.
The lip balm provided in Example 21 has the same raw materials as the lip balm provided in Example 17. However, the plant squalene composition in Example 21 has not been processed by the refining process, and its moisturizing effect is obviously inferior to that of Example 17, which indicates that the cosmetic obtained by applying the preferred method of the present invention to the raw materials through the refining process has a better moisturizing effect.
However, the cosmetics provided in Comparative Examples 7-12 respectively use the plant squalene com- position provided in Comparative Examples 1-6 of the present dis- closure respectively, and have relatively poor moisturizing ef-
fects. After 6 hours of use, the skin moisture content does not increase, or even decrease slightly. Although specific embodiments have been used to illustrate and describe the present disclosure, it should be appreciated that many other changes and modifications can be made without departing from the spirit and scope of the present disclosure. Therefore, this means that all these changes and modifications that fall within the scope of the present disclosure are included in the ap- pended claims.
Industrial applicability The preparation method of the plant squalene composition pro- vided by the present invention is not limited by the types of raw materials and ingredients, and is simple in process flow and low in cost. The prepared plant squalene composition has relatively stable ingredients. In addition to the plant squalene, the plant squalene composition also contains effective active substances such as natural vitamin E and plant sterols, and can be used for the preparation of cosmetics after simple refining. This method is suitable for the preparation of the plant squalene composition used in the production of cosmetics on a large scale.
