[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figure 1-2 As shown, the embodiment of the present invention provides a method for synthesizing microcrystalline cellulose, comprising the following steps:

[0033] S1. According to the desired ratio, water, microcrystalline cellulose and sodium benzoate are injected into a stirring device;

[0034] S2. Stir the mixed liquid for a suitable time;

[0035] S3. Heat the stirring space to a suitable range;

[0036] S4. Perform vacuum defoaming treatment on the stirred liquid.

[0037] This product has excellent suspension properties and can stably suspend a variety of solid ingredients such as flower petals, mica, Chinese medicine particles, etc., ensuring that the diverse ingredients are evenly distributed. Its nanostructure enhances the smoothness and application experience during use without affecting the formation and stability of foam. It is easy to operate and does not require pre-dissolution or activation, making it more convenient to use.

[0038] The proportion of water in S1 is 98.1% to 98.9%, the proportion of microcrystalline cellulose in S1 is 0.8% to 1.2%, and the addition of microcrystalline cellulose can enhance its dispersion effect by increasing the stirring rate.

Within the suitable temperature, the structure of cellulose can be avoided from being destroyed, the efficiency of mixing of various materials can be improved, and the suitable temperature can better dissolve other raw materials.

[0039] Example 2:

[0040] How to use:

[0041] 1. It has little effect on the viscosity of the system. It needs to have a consistency when added. During production, it is necessary to ensure sufficient stirring / low-speed homogenization for 30 minutes until it is completely dissolved;

[0042] 2. The most suitable suspension base formula for the product is recommended to be added at a dosage of more than 15%. The higher the surfactant content, the better the suspension power, which is conducive to forming a stable 3D suspension structure.

[0043] 3. 2.5% can suspend mica powder, etc.

[0044] 4. 2.5-5% can effectively suspend petals (real flowers);

[0045] 5. 2.5-6% can be used to suspend various particles (such as ginger, Chinese medicine, etc.);

[0046] 6. The product is compatible with anionic systems, but more testing is needed for cationic systems.

[0047] Among them, it is worth noting that:

[0048] 1. The long-term antifreeze (-18°C) surface of this product is not stable enough at present. Customers who need to test the antifreeze conditions can test it by themselves;

[0049] 2. The higher the amount of AES added, the higher the surfactant content, the better the suspension power and the better the transparency;

[0050] 3. Ensure that the added product system has appropriate sufficient viscosity;

[0051] 4. The formula cannot achieve complete transparency. There will be slightly acceptable blue light and fogging. Adding some pigments can enhance the transparent appearance of the product.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
