[0017] The shell powder is first heat-treated at 135~145℃ for 10~15min, then cooled to 48~52℃ at a rate of 1~3℃ / min, kept at that temperature, and then placed into a modification liquid of 5~10 times the total amount of shell powder for stirring and modification treatment. The stirring speed is 450~550r / min, and the stirring time is 1~2h. After stirring, the mixture is washed with water and dried to obtain the modified formulation.

[0018] Preferably, the pH value of the phosphate buffer solution is 5.0 to 6.0.

[0019] Preferably, the peppermint paste also contains 8-14 parts of attapulgite modifier;

[0020] The preparation method of the attapulgite soil conditioner is as follows:

[0021] S101: Heat the attapulgite clay to 120-130℃ at a rate of 2-5℃ / min and hold for 5-10 minutes. Then heat it to 210-220℃ at a rate of 1-3℃ / min and hold for 10-15 minutes. Finally, let it cool naturally to room temperature for later use.

[0022] S102: The spare attapulgite soil is fed into a conditioner with a weight of 5 to 10 times the total weight of the attapulgite soil and ultrasonically treated. After the treatment is completed, it is washed with water and dried to obtain the attapulgite soil conditioner.

[0023] The preparation method of the regulator is as follows:

Then, 8-12% of the total weight of the alcohol solution of yttrium nitrate solution and 4-8% of the total weight of the alcohol solution of sodium carboxymethyl cellulose were added to the alcohol solution and stirred until homogeneous. Then, 2-5% of the total weight of the alcohol solution of sodium citrate solution was added and mixed thoroughly to obtain the regulator.

[0025] Preferably, the ultrasonic power of the ultrasonic improvement treatment is 350~450W, and the ultrasonic time is 20~30min.

[0026] Preferably, the yttrium nitrate solution has a mass fraction of 2-5%; the sodium citrate solution has a mass fraction of 10-15%.

[0030] Step 3: Dissolve and stir the white petrolatum and paraffin at 110°C until homogeneous. Then add the raw materials prepared in Step 2 and control the temperature at 60°C. Mix and stir for 1-2 hours. After stirring, the peppermint paste of the present invention is obtained.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] The peppermint balm of this invention uses white petrolatum and paraffin, combined with menthol, trehalose, hydroxyethyl cellulose, glycerin, Tween-80 and a modifier to achieve a synergistic effect. The attapulgite clay modifier and the houttuynia cordata extract doped with nano-silica work together to achieve a synergistic effect. The prepared peppermint balm has a coordinated improvement in moisturizing effect, soothing effect on skin redness and swelling caused by mosquito bites, and antibacterial durability, thus improving the efficiency of product use.

[0033] The Houttuynia cordata extract doped with nano-silica is a synergistic improvement achieved by combining Houttuynia cordata extract with ball-milled nano-silica. The ball-milled nano-silica is then treated with hydrochloric acid solution to optimize its dispersibility and activity. A ball milling modifier, prepared by blending chitosan solution, hydroxy amino acids, sodium dodecylbenzenesulfonate, a modifying agent, and sodium silicate solution, further enhances the product's antibacterial durability through the synergistic effect of the raw materials. The optimized Houttuynia cordata extract doped with nano-silica further strengthens the system's properties. The modified formulation uses shell powder that has been heat-treated at 135-145℃ for 10-15 minutes and then cooled to 48-52℃ at a rate of 1-3℃ / min to optimize its activity. At the same time, the shell powder is modified by a modification solution composed of lanthanum sulfate solution, sodium lignosulfonate, phosphate buffer solution and tocopheryl acetate. The modified shell powder can better cooperate with nano-silica in the ball milling regulator. Through the mutual cooperation between the raw materials, the Houttuynia cordata extract doped with nano-silica can improve the moisturizing effect, soothe the skin redness and swelling caused by mosquito bites and have long-lasting antibacterial properties.

[0034] The attapulgite conditioner is prepared by first heating attapulgite to 120-130℃ at a rate of 2-5℃ / min and holding for 5-10 min, then heating it to 210-220℃ at a rate of 1-3℃ / min and holding for 10-15 min, and finally cooling it naturally to room temperature. Through multi-stage heating and heat treatment, the attapulgite is then added to ethanol with the specific silane coupling agent KH560 of this invention to prepare an alcohol solution. At the same time, yttrium nitrate solution, sodium carboxymethyl cellulose and sodium citrate solution are used to synergistically improve the attapulgite. The improved attapulgite can better cooperate with the Houttuynia cordata extract doped with nano-silica, thereby further enhancing the moisturizing, soothing and antibacterial durability of the product system and coordinating and improving the performance of the system.

[0142] Unlike Example 3, no hydroxy amino acids or sodium dodecylbenzenesulfonate were added during the preparation of the ball milling conditioner.

[0143] Comparative Example 4:

[0144] Unlike Example 3, sodium silicate solution was not added in the preparation of the ball milling conditioner.

[0145] Comparative Example 5:

[0146] Unlike Example 3, no modified formulation agent was added during the preparation of the ball milling conditioner.

[0147] Comparative Example 6:

[0148] Unlike Example 3, no attapulgite conditioner was added.

[0149] Comparative Example 7:

[0150] Unlike Example 3, S101 treatment was not used in the preparation of the attapulgite conditioner.

[0151] Comparative Example 8:

[0152] Unlike Example 3, the S101 treatment did not involve raising the temperature to 215°C at a rate of 2°C / min and holding it at that temperature for 12.5min.

[0153] Comparative Example 9:

[0154] Unlike Example 3, no conditioning agent was used in the preparation of the attapulgite conditioner.

[0155] Comparative Example 10:

[0156] The difference from Example 3 is the preparation method of the regulator: yttrium nitrate solution and sodium carboxymethyl cellulose were not added.

[0157] Antibacterial durability was measured using Staphylococcus aureus as an example to investigate the antibacterial rate immediately after testing, after 12 hours, and after 48 hours; at the same time, a skin moisture meter was used to test changes in skin moisture and to test the skin moisturizing rate of the product after 12 hours.

[0158] The participants were aged 25-45 years, including 65 men and 65 women. The 130 participants were divided into 13 groups of 10 each. The test product was applied to the skin once daily for 3 consecutive weeks. The participants' clinical presentation was facial skin redness and swelling due to insect bites.

[0159] No improvement in skin symptoms: 0 points; Mildly effective: 1 point; Moderately effective: 2 points; Effective: 3 points; Significantly effective: 4 points; Completely effective: 5 points. The score is obtained by evaluating the skin-soothing effect through a rating system based on the test subject's score.

[0160] The products of Examples 1-3 and Comparative Examples 1-10 were subjected to performance tests, and the test results are as follows:

[0161]

[0162] As can be seen from Comparative Examples 1-10 and Examples 1-3;

[0163] The product in Example 3 has an excellent 12-hour moisturizing rate, while the skin soothing effect score is significant and the antibacterial durability is significantly improved. From the immediate measurement to the 56-hour measurement, a long-lasting antibacterial effect can be achieved, and the product performance can achieve a significant and coordinated improvement.

[0164] As can be seen from Comparative Examples 1-6 and Example 3, when the Houttuynia cordata extract doped with nano-silica of the present invention is replaced with Houttuynia cordata extract liquid, the performance of the product deteriorates significantly. Furthermore, the performance of the Houttuynia cordata extract doped with nano-silica also deteriorates when the ball milling regulator is not used, or when hydroxy amino acids, sodium dodecylbenzenesulfonate, sodium silicate solution, or modified formulation agent is not added. Different methods of preparing the ball milling regulator all result in varying degrees of performance degradation. The absence of a modified formulation agent is the most significant factor affecting the performance of the product during the preparation of the ball milling regulator. Only the Houttuynia cordata extract doped with nano-silica prepared using the method of the present invention exhibits the most significant performance improvement.

[0165] As can be seen from Comparative Examples 1, 6 and 3, the inventors of the present invention also found that without the addition of attapulgite modifier, the performance of the product deteriorates significantly. The attapulgite modifier and the Houttuynia cordata extract doped with nano-silica work synergistically to significantly improve the performance of the product.

[0166] As can be seen from Comparative Examples 7-10 and Example 3, the performance of the product deteriorates significantly when no synergistic modifier is added. Furthermore, the performance of the product tends to deteriorate depending on the preparation method of the synergistic modifier.

[0167] In the preparation of attapulgite conditioner, the S101 treatment was not used; in the S101 treatment, the temperature was not raised to 215℃ at a rate of 2℃ / min and held for 12.5min; in the preparation of attapulgite conditioner, no conditioner treatment was used; and the preparation method of the conditioner was different: yttrium nitrate solution and sodium carboxymethyl cellulose were not added. The performance of the product tended to deteriorate in all these cases. Only when the S101 process obtained by the method of this invention is combined with the conditioner prepared by the method of this invention, and they work together in a coordinated manner, can the performance of the product be most significant.

[0168] This invention further explores the product performance through the preparation of modified formulation agents;

[0169] The preparation method of the modified formulation agent is as follows:

[0170] 3.5 parts of 7.5% lanthanum sulfate solution, 2 parts of sodium lignosulfonate, 0.20 parts of phosphate buffer solution, and 1.5 parts of tocopherol acetate were stirred and mixed to obtain the modified solution.

[0171] The shell powder was first heat-treated at 140℃ for 12.5 min, then cooled to 50℃ at a rate of 2℃ / min, kept at that temperature, and then placed into a modification liquid with a volume of 7.5 times the total volume of the shell powder for stirring and modification treatment. The stirring speed was 500 r / min, and the stirring time was 1.5 h. After stirring, the mixture was washed with water and dried to obtain the modified formulation.

[0172] The pH value of the phosphate buffer solution in this embodiment is 5.5.

[0173] Experimental Example 1:

[0174] Same as Example 3, except that the modified formulation was not heat-treated at 140°C for 12.5 min and then cooled to 50°C at a rate of 2°C / min.

[0175] Experimental Example 2:

[0176] Same as Example 3, except that no modified liquid treatment was used.

[0177] Experimental Example 3:

[0178] Same as Example 3, except that sodium lignosulfonate and phosphate buffer solution were not added in the preparation of the modified liquid.

[0179] Experiment Example 4:

[0180] Same as Example 3, except that tocopherol acetate was not added in the preparation of the modified liquid.

[0181] Experimental Example 5:

[0182] Same as Example 3, except that deionized water was used instead of lanthanum sulfate solution in the preparation of the modified solution.

[0183] The performance test results of Examples 1-5 are as follows:

[0184]

[0185] As can be seen from Experiments 1-5, the performance of the product deteriorated significantly when the modified formulation was not heat-treated at 140℃ for 12.5 min followed by cooling to 50℃ at a rate of 2℃ / min, or when the modified liquid treatment was not used. Furthermore, the performance of the product deteriorated when sodium lignosulfonate and phosphate buffer solution were not added to the modified liquid, tocopheryl acetate was not added, or deionized water was used instead of lanthanum sulfate solution. Only the modified formulation obtained by combining the modified liquid prepared by the method of this invention with the process method of this invention showed the most significant performance improvement. Other methods were not as effective as those of this invention.
