[0034] like Figure 1 As shown, the whitening body lotion provided in this embodiment includes a solvent, emollient, moisturizer, skin protectant, whitening agent, emulsifier, thickener, preservative, and pH adjuster. Based on 100% by weight, the body lotion comprises the following components by weight percentage: solvent 77.78%, emollient 5.3%, moisturizer 4.12%, skin protectant 4.05%, whitening agent 4%, emulsifier 2.5%, thickener 1.4%, preservative 0.65%, and pH adjuster 0.2%. The solvent's main component is water, used to dissolve various raw materials. Water also helps maintain the stability of the reaction environment because it has a strong buffering capacity, stabilizing the solution's pH and ion concentration, thus keeping the reaction environment stable.

[0035] In this embodiment, the skin protectant includes extracts of *Saussurea involucrata* flower, *Nymphaea leucocephala* flower, *Ginkgo biloba* root, *Lithospermum erythrorhizon*, *Euphorbia pekinensis* extract, p-hydroxyacetophenone, 1,2-hexanediol, butylene glycol, water, tocopherol, bisabolol, allantoin, and jasmine flower oil; the moisturizer includes propylene glycol and sodium hyaluronate; the emollient includes ethylhexyl palmitate, oleyl erucic acid ester, and polydimethylsiloxane; the whitening agent includes niacinamide and α-arbutin; the emulsifier includes C14-22 alcohol, C12-20 alkyl glucoside, glyceryl stearate, and PEG-100 stearate; the thickener includes cetearyl alcohol, acrylate / C10-30 alkanol acrylate crosspolymer, and xanthan gum; and the preservative includes phenoxyethanol, 1,2-hexanediol, chlorphenesin, water, methylparaben, and propylparaben.

[0036] The extract of Saururus chinensis flower contains volatile oils, flavonoids, lignans, alkaloids, tannins, and other components, which have anti-inflammatory activity and can be used for acne prevention and treatment.

[0037] White water lily extract has moisturizing and anti-aging effects on the skin. White water lily has a natural mucus that can greatly improve the skin's moisture. Its extremely high vitamin C content gives it powerful antioxidant, skin structure rebuilding and skin conditioning abilities. In addition, the alkaloid components in white water lily can soothe skin itching, help skin regeneration, and also have a whitening effect. The flavonoids, polyphenols and other active ingredients it contains can make the skin white and translucent.

[0038] Ginkgo biloba and Lithospermum root extracts are mainly used as antioxidants and anti-inflammatory agents in body lotions, playing a role in fighting skin fungi and viruses.

[0039] The combined use of propylene glycol and sodium hyaluronate moisturizes, lubricates, and promotes absorption of the skin, thereby enhancing the moisturizing effect of body lotion and reducing the occurrence of dry and peeling skin.

[0040] In this embodiment, the 4.05% skin protectant comprises the following components by weight percentage: 0.00066% of *Saussurea involucrata* flower extract, 0.078% of *Nymphaea leucocephala* flower extract, 0.0534% of *Ginkgo biloba* and *Lithospermum erythrorhizon* root extract, 0.0711% of *Isodon spp.* extract, 0.015% of p-hydroxyacetophenone, 0.015% of 1,2-hexanediol, 0.24% of butylene glycol, 2.52684% of water, 0.5% of tocopherol, 0.3% of bisabolol, 0.2% of allantoin, and 0.05% of jasmine flower oil. Among these, bisabolol has anti-inflammatory and antibacterial effects, reducing the irritation of human skin caused by chemical factors, and playing a preventive and inhibitory role in the occurrence and treatment of inflammation, making it suitable for the care of sensitive skin.

[0041] In this embodiment, the 0.65% preservative comprises the following components by weight percentage: 0.16% phenoxyethanol, 0.128% 1,2-hexanediol, 0.08% chlorphenesin, 0.032% water, 0.15% methylparaben, and 0.1% propylparaben;

[0042] In this embodiment, the 5.3% emollient comprises the following components by weight percentage: 4% ethylhexyl palmitate, 0.5% oleyl erucic acid ester, and 0.8% polydimethylsiloxane. The 0.2% pH adjuster comprises the following components by weight percentage: 0.2% triethanolamine. Ethylhexyl palmitate, as an emollient oil, has good breathability and spreadability, making it an excellent skin emollient that improves the smoothness of body lotion application. Meanwhile, polydimethylsiloxane has a low risk factor, is non-comedogenic, and also acts as an emollient to produce a lubricating and silky feel.

[0043] In this embodiment, the moisturizer 4.12% comprises the following components by weight percentage: propylene glycol 4% and sodium hyaluronate 0.12%. The whitening agent 4% comprises the following components by weight percentage: niacinamide 2% and α-arbutin 2%. Niacinamide can accelerate skin cell metabolism, promote the circulation of the stratum corneum, and make the skin younger and more vibrant. It also has a certain antioxidant effect, which can keep the skin elastic, whiten and remove spots, repair the stratum corneum, strengthen the skin's own defense ability, and has a certain water-locking effect. α-Arbutin has anti-inflammatory and antibacterial effects, and can have a good inhibitory effect on some skin allergies and inflammation. In combination with niacinamide, it can improve the whitening effect.

[0044] In this embodiment, the 2.5% emulsifier comprises the following components by weight percentage: 1.2% C14-22 alcohol, 0.3% C12-20 alkyl glucoside, 0.39% glyceryl stearate, and 0.61% PEG-100 stearate;

[0045] In this embodiment, the thickener 1.4% comprises the following components by weight percentage: 1% cetearyl alcohol, 0.2% acrylate / C10-30 alkanol acrylate crosspolymer, and 0.2% xanthan gum. Cetearyl alcohol can suppress greasiness, thicken water-based formulations, and is considered safe and harmless to the human body by the cosmetic ingredient review group. Xanthan gum has the effects of relieving dry skin, anti-oxidation, and is also non-toxic and can provide moisturizing effects.

[0046] like Figure 1 As shown in the figure, the preparation method of a whitening body lotion provided in this embodiment includes the following steps:

[0047] S1: First, mix phase A with water phase in a pot and heat to 85±3°. Add the evenly dispersed phase A1 and stir and keep warm for 10 minutes.

[0048] S2: Then mix phase B with the oil phase in the pot, stir and heat to 85±3°C, and keep warm for 10 minutes;

[0049] S3: After the A phase filter is drawn into the main pot and stirred, the B phase filter is drawn into A and mixed completely. Then, the mixture is homogenized at high speed for 5 minutes, kept warm and stirred for 20 minutes, and then the circulating water is turned on to slowly cool down.

[0050] S4: Stir and cool the C phase to 65±3 degrees Celsius;

[0051] S5: At 45±2°, add a small amount of solvent, α-arbutin, and the remaining D phase material in sequence and stir until homogeneous.

[0052] S6: Conduct physicochemical tests when the temperature drops below 40°C;

[0053] S7: After the physicochemical indicators pass the test, turn off the cooling water and discharge the material to stand for microbial testing.

[0054] S8: After passing the microbiological inspection, fill and print the code.

[0055] In this embodiment, the α-arbutin added in step S5 is α-arbutin that has been dissolved in a small amount of solvent beforehand. The dissolved α-arbutin is more stable, less prone to decomposition or inactivation, and more easily absorbed by the human body.
