[0073] The various substances in the moisturizing soothing cream have the following functions: water is mainly used as a solvent, and water is also used for the preparation of other components. Butylene glycol, Centella asiatica extract, Boswellia serrata extract and an appropriate amount of water are mixed as the first skin conditioner. The butylene glycol in the first skin conditioner can lock the moisture on the skin surface, mainly plays the role of moisturizing, gentle and soothing, Centella asiatica extract plays the role of anti-inflammatory and freckle whitening, Boswellia serrata extract plays the role of anti-inflammatory and oil control, and water is used to prepare these substances together. Mineral oil is an emollient, which plays an emollient role. Mineral oil is also suitable for the demand of high moisturizing during the emollient process. Biosaccharide gum-1, an appropriate amount of phenoxyethanol and an appropriate amount of water are mixed as the first moisturizing agent. The biosaccharide gum-1 in the first moisturizing agent has a long-lasting moisturizing performance, and phenoxyethanol plays an antibacterial role. Glycerin is a moisturizing agent, and the moisturizing effect of glycerin is relatively mild. It is used in combination with other moisturizing ingredients to play a better moisturizing effect. PEG-100 stearate and glyceryl stearate are mixed as the first emulsifier, and PEG-20 stearate and an appropriate amount of cetearyl alcohol are mixed as the second emulsifier. The emulsifying effects of these two emulsifiers are different. The former has a stronger emulsifying effect, while the latter has a thinner emulsifying effect. The combination makes the concentration after emulsification appropriate. The remaining cetearyl alcohol is an emulsifying stabilizer, which plays an emulsifying and stabilizing role in the preparation process of the moisturizing soothing cream. Polydimethylsiloxane is a sealing agent, which forms a thin film on the skin surface to prevent water loss. Glyceryl phosphoinositol choline salt, an appropriate amount of phenoxyethanol, an appropriate amount of ethylhexylglycerol and an appropriate amount of water are mixed as the second skin conditioning agent. The glyceryl phosphoinositol choline salt in the second skin conditioning agent is used for anti-allergy and anti-drying, phenoxyethanol is used for antibacterial, ethylhexylglycerol has moisturizing and antibacterial effects, and water is used to mix these substances together. An appropriate amount of phenoxyethanol and an appropriate amount of ethylhexylglycerol are mixed as the first preservative, and propylene glycol, o-cymene-5-ol, 1,2-hexanediol and an appropriate amount of ethylhexylglycerol are mixed as the second preservative. The two preservatives are used together to inhibit different microorganisms. Carbomer is a thickener. Tocopherol acetate is an antioxidant and plays an antioxidant role. Allantoin is a skin conditioning agent that plays a moisturizing, repairing, soothing, anti-inflammatory and antioxidant role. Dipotassium glycyrrhizinate is a skin conditioning agent that plays an anti-inflammatory, anti-allergic and moisturizing role. Lavender oil is a skin conditioning agent that plays a moisturizing, oil control, anti-inflammatory, calming and soothing role. Sodium hydroxide is a pH regulator used to adjust pH. Some of the effects of some of the above components overlap, but the mechanisms for achieving the same effect are different. For example, there are multiple moisturizing components, but the moisturizing mechanisms are different. There will be no conflict when used together, and the moisturizing soothing cream can adapt to different skin types.

[0104] Glycerin, glyceryl stearate, PEG-100 stearate, propylene glycol, PEG-20 stearate, ethylhexylglycerin contain potential diethylene glycol risk. The EU began to implement the EU Cosmetics Regulation 1223 / 2009 / EC on July 11, 2013. In this regulation, diethylene glycol is prohibited from being used as a raw material in cosmetics, and it is stipulated that the content of diethylene glycol as an impurity in the raw material in the final cosmetic product should be ≤0.1%. After evaluation, the content of diethylene glycol brought in by this ingredient meets the safety requirements, so this product is safe. See the inspection report of this product in the table below for details.

[0105] PEG-100 stearate, phenoxyethanol, and PEG-20 stearate contain potential dioxin risks. The dioxin test results of this product meet the regulatory requirements. The dioxin residue meets the requirements of the "Cosmetic Safety Technical Specifications" (2015 edition), which stipulates that the dioxin limit value in cosmetics should not exceed 30 mg / kg. Please see the inspection report of this product in the table below for details.

[0106] The risk substance that Carbomer may contain is benzene. According to the notice of the State Food and Drug Administration on incorporating 21 formulation and revision items such as the pH determination method of oil-in-water cosmetics into the Cosmetic Safety Technical Specifications (2015 Edition) (No. 41 of 2023): If it is technically impossible to avoid benzene from being introduced into cosmetics as an impurity, its limit shall not exceed 2 mg / kg. The test report results of "benzene" provided by the raw material supplier used in this product show that the benzene impurity in this raw material is less than 2 mg / kg, and its use meets the requirements. Therefore, this raw material does not have a safety risk and will not cause potential harm to human health.

[0107] The risk substances that may be contained in lavender oil, Centella asiatica extract, and Boswellia serrata extract are pesticide residues. According to the State Food and Drug Administration's "Guidelines for Risk Assessment of Safety Risk Substances that May Exist in Cosmetics" (Guo Shi Yao Jian Xu

[2010] No. 339), Article 5, Item 7, requires a pesticide residue statement. This raw material is not used directly after mechanical processing, but is pressed, extracted, precipitated, etc. As a non-pure crude processed raw material, there is no risk of pesticide residues. As far as this product is concerned, there are no safety risk substances. Please see the inspection report in the table below for details.
