Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, specifically to a mild and soothing baby wash and its preparation method. Background Technology

[0002] Shower gel, a cleansing agent used during bathing, comes in two types: alkaline and acidic. Its ingredients include chemically produced soda and stabilizers, foam stabilizers, fragrances, thickeners, chelating agents, skin care agents, colorants, and some functional ingredients such as herbal extracts, hydrolyzed proteins, vitamins, and lanolin derivatives. However, traditional baby shampoos and body washes have a series of problems, such as high irritation to infants' skin, the potential production of dangerous substances like dioxane and formaldehyde, and unsuitability for long-term use. Infants' skin takes several years to develop to the same level as adult skin, making it particularly delicate and sensitive during this period, prone to irritation and infection. Modern young parents increasingly value the quality of baby products and toiletries, but existing baby products in my country need improvement in terms of variety, quality, and functionality. Many raw materials are chemically synthesized, failing to meet market demand. Given the problems of high irritation and potential hazardous substance residues in existing baby shampoos and body washes, there is a need to develop a gentle and soothing shower gel suitable for infants. Its formula must avoid skin irritation and ensure it does not contain ingredients that may leave harmful residues.

[0003] To address the aforementioned issues and improve the cleansing and gentleness of bath products, this invention provides a gentle and soothing bath product suitable for infants and its preparation method. Summary of the Invention

[0004] The purpose of this invention is to provide a mild and soothing baby bath wash and its preparation method, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A method for preparing a mild and soothing baby bath wash includes the following steps: taking modified coconut oil fatty acid diethanolamide, cocamidopropyl betaine, sucrose fatty acid ester, moisturizer, sorbitol, emulsifier, and deionized water, heating to 50-60℃, stirring for 20-40 minutes, cooling to 25-35℃, adding aloe vera powder and citric acid, and stirring for 10-30 minutes to obtain the bath wash.

[0007] A more optimized method for preparing the modified coconut oil fatty acid diethanolamide is as follows: take carboxymethylated jujube polysaccharide, coconut oil fatty acid diethanolamide, and deionized water, stir evenly, heat to 55-60℃, and react for 10-12 hours to obtain the modified coconut oil fatty acid diethanolamide.

[0008] A more optimized method for preparing the carboxymethylated jujube polysaccharide includes the following steps:

[0009] Step 1: Take red dates, wash, remove pits, dry, and pulverize to obtain red date powder; take red date powder, add distilled water, heat to 80-85℃, extract, filter, centrifuge, add ethanol, let stand at 4-5℃ for 12-14 hours, precipitate, wash, and dry to obtain red date polysaccharide;

[0010] Step 2: Take jujube polysaccharide and sodium hydroxide solution, heat to 48-52℃, stir for 30-40 minutes, add chloroacetic acid, heat to 65-70℃, stir for 5-6 hours, add glacial acetic acid dropwise, adjust the pH value to 5-5.5, dialyze with deionized water and freeze dry to obtain carboxymethylated jujube polysaccharide.

[0011] In a more optimized manner, the aloe vera powder is prepared as follows: take aloe vera leaves, wash, dry, and cut them into pieces; take the cut aloe vera leaves, add chitosan aqueous solution, soak for 30-40 seconds, remove, juice, homogenize under a pressure of 120 MPa, filter, centrifuge, and freeze-dry the supernatant under vacuum to obtain aloe vera powder.

[0012] More preferably, the shower gel comprises the following ingredients by weight: 1-2 parts modified coconut oil fatty acid diethanolamide, 1-2 parts cocamidopropyl betaine, 0.7-0.9 parts sucrose fatty acid ester, 3-4 parts moisturizer, 1-2 parts sorbitol, 2-3 parts emulsifier, 75-85 parts deionized water, 12-15 parts aloe vera powder, and 0.2-0.7 parts citric acid.

[0013] More preferably, the emulsifier is polyglycerol-10 oleate.

[0014] Ideally, the moisturizer is glycerin.

[0015] Ideally, the mass ratio of the modified coconut oil fatty acid diethanolamide to cocamidopropyl betaine is 1:1.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] (1) This invention addresses the unique characteristics of infant skin and the problems existing in current bath products by providing a mild and soothing bath product and its preparation method. This bath product uses milder surfactants such as coconut oil fatty acid diethanolamide and cocamidopropyl betaine, avoiding irritation to infant skin. Furthermore, the bath product of this invention contains natural aloe vera powder. Aloe vera contains natural anthraquinone glycosides or anthraquinone derivatives, which can absorb ultraviolet rays and prevent skin damage from prolonged sun exposure. Aloe vera powder also has excellent moisturizing properties, is non-irritating to infant skin, and provides good hydration.

[0018] (2) Jujube polysaccharide is an important natural component of jujube, which has antioxidant and antibacterial effects. Carboxylation treatment of jujube polysaccharide enhances its solubility in water.

[0019] This invention's shower gel contains surfactants coconut oil fatty acid diethanolamide and cocamidopropyl betaine. The coconut oil fatty acid diethanolamide surfactant is modified using carboxylated jujube polysaccharide. The jujube polysaccharide has a molecular weight greater than 50,000, increasing the molecular weight of the modified coconut oil fatty acid diethanolamide. This higher molecular weight allows for better adhesion during cleaning, aiding in the removal of dirt and grease. However, an excessively large molecular weight can lead to more residue after rinsing, affecting the cleanliness. Furthermore, a large molecular weight can affect foam formation and stability, resulting in poor foaming performance, which is also detrimental to dirt removal.

[0020] This invention adds cocamidopropyl betaine with a small molecular weight for compounding, and controls the mass ratio of modified coconut oil fatty acid diethanolamide and cocamidopropyl betaine to 1:1. The small molecular weight of cocamidopropyl betaine gives the shower gel a lower surface tension, which helps to better moisturize and penetrate the skin surface, and at this time, the foaming performance is good and the shower gel has a good cleaning ability.

[0084] Experiment: The shower gels prepared in Examples 1 to 3 and Comparative Examples 1 to 3 were used for performance testing. The shower gels prepared in Examples 1 to 3 were used for irritation testing. A 5% aqueous solution of the shower gel was prepared using deionized water, and 0.5g of zein was added. The solution was stirred thoroughly, filtered, and the filtrate was used to test the irritation of the shower gel using the Kjeldahl method according to GB50095-2010. The shower gels prepared in Examples 1 to 3 and Comparative Examples 1 to 3 were used for foaming performance testing using a foaming apparatus according to GB / T7462-1994. The data obtained are shown in the table below:

[0085]

[0086] Conclusion: The data comparison in the table shows that the structure of zein is similar to that of keratin in human skin. Zein reacts with irritating substances, leading to its dissolution. In Examples 1 to 3, the amount of zein dissolved was small, less than 0.3g, proving that the shower gel prepared by this invention contains fewer irritating components, making it gentle, soothing, and skin-friendly for infants, without causing irritation. Comparative Example 1, without modification using jujube polysaccharide, showed a decrease in foaming performance. Comparative Example 2 controlled the mass ratio of modified coconut oil fatty acid diethanolamide and cocamidopropyl betaine to 1:0.5. Comparative Example 3 did not add cocamidopropyl betaine; in this case, only modified coconut oil fatty acid diethanolamide was added, resulting in an excessively large molecular weight, which affected foam formation and stability, leading to poor foaming performance, less foam, and hindering dirt removal. In Examples 1 to 3 of this invention, cocamidopropyl betaine with a small molecular weight was added for compounding, and the mass ratio of modified coconut oil fatty acid diethanolamide and cocamidopropyl betaine was controlled at 1:1. The small molecular weight of cocamidopropyl betaine makes the shower gel have a lower surface tension, which helps to better moisturize and penetrate the skin surface. At this time, the foaming performance is good and the cleaning ability of the shower gel is excellent.

[0087] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
