Description

Technical Field

[0001] The present invention relates to the field of daily necessities, and in particular to a bath salt ball and a preparation method thereof. Background Art

[0002] Bath salt balls are a type of bath product. Their main ingredients include baking soda, citric acid, corn starch, sea salt, essential oils, and pigments. These ingredients work together to deliver multiple benefits to the skin. Compared to single-use bath products like shower gel and soap, bath salt balls offer a wider range of functions and are more engaging. Adding toys to bath salt balls can further enhance the user experience, especially for children. As the bath salt ball dissolves, the toys revealed can effectively distract children, relieve their crying, and soothe them.

[0003] Currently, the bath salt balls with toys added inside on the market are all made of hard materials. Due to the limitations of the composition of the bath salt balls themselves, elastic toys cannot be added during the process of pressing them into balls. This directly limits the types of toys contained in the bath salt balls and cannot meet the diversified needs of the market. Summary of the Invention

[0004] The object of the present invention is to provide a bath salt ball, wherein toys made of different materials can be placed in the built-in toys without being restricted by the softness or hardness of the materials, thereby broadening the types and applications of the bath salt ball.

[0005] Another object of the present invention is to provide a method for preparing bath salt balls, which is simple, efficient and has a high yield.

[0006] The present invention solves the technical problem by adopting the following technical solutions.

[0007] In one aspect, an embodiment of the present invention provides a bath salt ball, comprising at least one toy and a bath salt ball body for covering the toy, wherein the bath salt ball body comprises the following raw materials by mass percentage:

[0008] Baking soda 40-50%, sodium sulfate 10-20%, soda ash 3-8%, sodium tripolyphosphate 1-2%, anhydrous citric acid 20-30%, PEG-400 polyethylene glycol 1-3%, fragrance 0.5-1%, pigment 0.1-0.5%, sodium alkylbenzene sulfonate powder 001-0.5%.

[0009] In some embodiments of the present invention, the bath salt ball body comprises the following raw materials by mass percentage:

[0011] In some embodiments of the present invention, the bath salt ball body comprises the following raw materials by mass percentage:

[0012] Baking soda 40%, sodium sulfate 20%, soda ash 6%, sodium tripolyphosphate 2%, anhydrous citric acid 30%, PEG-400 polyethylene glycol 1%, fragrance 0.5%, pigment 0.25%, sodium alkylbenzene sulfonate powder 0.25%.

[0013] On the other hand, an embodiment of the present invention provides a method for preparing a bath salt ball, comprising the following steps:

[0014] S1, mixing baking soda, sodium sulfate, soda ash, sodium tripolyphosphate, PEG-400 polyethylene glycol, spices, pigments, and sodium alkylbenzene sulfonate powder, sieving, adding anhydrous citric acid, and stirring to obtain a raw material mixture;

[0015] S2, pressing and molding the raw material mixture obtained in step S2 to obtain a first bath salt ball body and a second bath salt ball body having a receiving cavity;

[0016] S3, placing the toy in the receiving cavity of the first bath salt ball body, then covering the receiving cavity with the second bath salt ball body, performing a second pressing, connecting the first bath salt ball body and the second bath salt ball body, and thus obtaining the bath salt ball.

[0017] In some embodiments of the present invention, step S3 further includes drying the first bath salt ball body before placing the toy in the receiving cavity of the first bath salt ball body.

[0018] In some embodiments of the present invention, the drying temperature is between 18-40°C.

[0019] In some embodiments of the present invention, in step S2, the pressure for pressing and molding is 500 kg, that is, the pressure for pressing and molding each bath salt ball is the gravity exerted by a 500 kg weight, specifically, the pressure is provided by hydraulic pressure.

[0020] In some embodiments of the present invention, the first bath salt ball body and the second bath salt ball body are both hemispherical in shape.

[0021] In some embodiments of the present invention, the first bath salt ball body is hemispherical in shape, and the second bath salt ball body is plate-shaped.

[0022] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0023] The bath salt ball provided by the present invention has toys placed inside it to increase the fun of bathing, and the bath salt ball body comprises baking soda, sodium sulfate, soda ash, sodium tripolyphosphate, anhydrous citric acid, PEG-400 polyethylene glycol, spices, pigments, and sodium alkylbenzene sulfonate powder. With baking soda and anhydrous citric acid as the main raw materials, baking soda (sodium bicarbonate) reacts with citric acid to generate carbon dioxide gas when it meets water, producing a violent explosion effect, so that the bath salt ball dissolves rapidly in water and releases rich foam. And the baking soda aqueous solution is weakly alkaline, has good deodorizing and cleaning effects, and can effectively remove dirt, scale and odor on the skin surface. Sodium sulfate (sodium sulfate) has certain cleaning ability and can assist in removing dirt and aging keratin on the skin surface. It can also soften skin keratin, making the skin smoother and more delicate. Soda ash (sodium carbonate): can soften hard water, reduce the surface tension of water, make bath water more gentle, and reduce irritation to the skin. It also helps to promote blood circulation and relieve muscle fatigue and pain. Sodium tripolyphosphate: As a chelating agent, it effectively binds calcium and magnesium ions in water, softening it and preventing scale buildup. It enhances the bath salts' cleaning ability, reduces soap scum residue, and promotes a more refreshing bath. Citric acid, containing vitamin C, whitens and moisturizes the skin, improving uneven skin tone and dryness. Citric acid also promotes skin metabolism, helping to eliminate fatigue and leaving skin smoother and more delicate. PEG-400: Its excellent water solubility stabilizes the bath salts' formula and prevents ingredient separation. It also exhibits lubricating, dispersing, and emulsifying properties, improving the speed and uniformity of the bath salts' dissolution in water, making bathing more comfortable. Fragrances add a pleasant aroma to the bath salts, creating a relaxing atmosphere that helps relieve stress and improve sleep. Different fragrances can also provide different sensory experiences, making the bath more enjoyable. Pigments add rich colors to the bath salts, enhancing their visual appeal and making bathing more fun and enjoyable. Sodium alkylbenzene sulfonate powder has powerful cleaning properties, effectively removing dirt and oil from the skin's surface. At the same time, it can also produce rich foam, enhancing the cleansing effect of bathing. As a surfactant, it can also emulsify the oil and dirt on the skin surface, making it easier to be washed away by water.

[0024] The various ingredients in the bath salt balls work together to achieve multiple functions such as cleansing, softening cuticles, whitening and moisturizing, eliminating fatigue, adding fragrance and color, etc., bringing pleasure and enjoyment to the bathing process.

[0025] The preparation method of bath salt balls provided by the present invention comprises the following steps: uniformly mixing the raw materials, stirring them to cause an acid-base reaction to occur in the raw materials, generating a certain viscosity, and then pressing and molding them into a shape having a cavity, into which a toy can be placed. As long as the toy's shape can be placed in the cavity, there is no need to limit the soft or hard material of the toy. The cavity is then sealed to obtain a complete bath salt ball. When making traditional bath salt balls, the toy is directly mixed with the raw materials of the bath salt balls, and then pressed and molded, which is only suitable for hard stationery. The preparation method provided by the present invention, through two-step pressing and molding, is suitable for soft toys, broadening the types of bath salt balls. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer are used. Where the manufacturer of the reagents or instruments is not specified, all are conventional products that can be purchased commercially.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to specific embodiments.

[0035] An embodiment of the present invention provides a bath salt ball, comprising at least one toy and a bath salt ball body for covering the toy. The bath salt ball body comprises the following raw materials by mass percentage:

[0036] Baking soda 40-50%, sodium sulfate 10-20%, soda ash 3-8%, sodium tripolyphosphate 1-2%, anhydrous citric acid 20-30%, PEG-400 polyethylene glycol 1-3%, fragrance 0.5-1%, pigment 0.1-0.5%, sodium alkylbenzene sulfonate powder 001-0.5%.

[0037] Preferably, the bath salt ball body comprises the following raw materials by mass percentage:

[0038] Baking soda 50%, sodium sulfate 15%, soda ash 5%, sodium tripolyphosphate 1%, anhydrous citric acid 25%, PEG-400 polyethylene glycol 2%, fragrance 1%, pigment 0.5%, sodium alkylbenzene sulfonate powder 0.5%.

[0039] Preferably, the bath salt ball body comprises the following raw materials by mass percentage:

[0040] Baking soda 40%, sodium sulfate 20%, soda ash 6%, sodium tripolyphosphate 2%, anhydrous citric acid 30%, PEG-400 polyethylene glycol 1%, fragrance 0.5%, pigment 0.25%, sodium alkylbenzene sulfonate powder 0.25%.

[0041] The effects of each raw material are:

[0042] When baking soda (sodium bicarbonate) and citric acid are mixed, they react with water to produce carbon dioxide gas, creating a violent explosion that rapidly dissolves the bath salt balls in the water and releases rich foam. Baking soda solutions are also weakly alkaline, providing excellent deodorizing and cleaning properties, effectively removing dirt, scale, and odor from the skin's surface.

[0043] Sodium sulfate has a certain cleaning ability, which can help remove dirt and aging cuticles on the skin surface. It can also soften the skin cuticles and make the skin smoother and more delicate.

[0044] Soda ash (sodium carbonate): It softens hard water and reduces its surface tension, making bath water gentler and less irritating to the skin. It also helps promote blood circulation and relieve muscle fatigue and pain.

[0045] Sodium tripolyphosphate: As a chelating agent, it effectively binds calcium and magnesium ions in water, softening it and preventing scale buildup. It also enhances the cleaning power of bath salts, reducing soap scum residue and providing a more refreshing bath.

[0046] Citric acid contains vitamin C, which has a whitening and moisturizing effect on the skin, and can improve uneven skin tone and dryness. Citric acid also promotes skin metabolism, helps eliminate physical fatigue, and makes the skin smoother and more tender.

[0047] PEG-400 polyethylene glycol: With excellent water solubility, it stabilizes the bath salt ball formula and prevents ingredient separation. It also exhibits lubricating, dispersing, and emulsifying properties, increasing the speed and uniformity of the bath salt ball's dissolution in water, making bathing more comfortable.

[0048] The spices add a pleasant aroma to the bath salt balls, creating a relaxing atmosphere that helps relieve stress and improve sleep. Different spices can also bring different sensory experiences, making the bathing process more enjoyable. In the embodiments of the present invention, the spices are commonly used in the art and can be plant spices or synthetic spices.

[0049] The pigment adds rich colors to the bath salt balls, enhances visual appeal, and makes the bathing process more interesting and enjoyable. In an embodiment of the present invention, the pigment is a pigment commonly used in the art, and can be a plant pigment or a synthetic pigment.

[0050] Sodium alkylbenzene sulfonate powder has a strong detergency, effectively removing dirt and oil from the skin's surface. It also produces rich foam, enhancing the cleansing effect of bathing. As a surfactant, it also emulsifies oil and dirt on the skin's surface, making it easier to rinse away with water.

[0051] The preparation method of the bath salt balls comprises the following steps:

[0052] S1, mixing baking soda, sodium sulfate, soda ash, sodium tripolyphosphate, PEG-400 polyethylene glycol, spices, pigments, and sodium alkylbenzene sulfonate powder, sieving, adding anhydrous citric acid, and stirring to obtain a raw material mixture;

[0053] S2, pressing and molding the raw material mixture obtained in step S2 to obtain a first bath salt ball body and a second bath salt ball body having a receiving cavity;

[0054] S3, placing the toy in the receiving cavity of the first bath salt ball body, then covering the receiving cavity with the second bath salt ball body, and performing a second pressing to connect the first bath salt ball body and the second bath salt ball body to obtain the bath salt ball. During the second pressing, the first bath salt ball body and the second bath salt ball body have a certain viscosity under the action of pressure, allowing them to be connected together. Alternatively, a small amount of water or adhesive can be added to the interface and then applied with pressure to connect the first bath salt ball body and the second bath salt ball body.

[0055] Preferably, step S3 further includes drying the first bath salt ball body and then placing the toy into the receiving cavity of the first bath salt ball body. By drying the first bath salt ball body to harden its shape, the first bath salt ball body and its cavity have a certain hardness, so that a toy made of soft, elastic material can be inserted into the cavity without breaking the first bath salt ball body. The second bath salt ball body is then placed over the first bath salt ball body to seal the cavity. Although the first bath salt ball body has been dried and its viscosity has decreased, the second bath salt ball body still has a certain viscosity, and the two can still be connected together when the mold is formed to match.

[0056] The drying temperature is 18-40° C. In step S2 , the pressing pressure is 500 kg. In some embodiments, the shapes of the first bath salt ball body and the second bath salt ball body are both hemispherical.

[0057] In some embodiments, the first bath salt ball body is hemispherical, and the second bath salt ball body is plate-shaped. The plate-shaped second bath salt ball body does not have a receiving cavity. Preferably, the first bath salt ball body is a sphere with a hole, forming a cavity inside. The soft toy can be inserted into the cavity through the hole and then sealed with a cover.
