Description

Technical Field

[0001] The invention relates to the technical field of daily chemical industry, in particular to a water-soluble bubble powder. Background Art

[0002] Bubble water has a wide range of uses, from daily toys to large stage decorations. Bubble water blows out colorful bubbles floating in the air, bringing children endless fun. The safety and transportation convenience of bubble water are also attracting more and more attention. The common formulas for homemade bubble water at home are: ① tea + detergent + sugar; ② soap + tea + sugar; ③ detergent + water + sugar; ④ glue + water + detergent + hand soap (shampoo). However, the above formula has a general bubble blowing effect, the bubbles are not rich enough and easy to break, and may cause children to eat them by mistake. At present, most of the commercial bubble water and bubble water concentrates sold on the market are bubble water with polyoxyethylene ether copolymers and dimethyl diallyl ammonium chloride-acrylamide copolymers as foam stabilizers. Under certain conditions, they will decompose and precipitate, producing high molecular compounds and toxic odors, which can irritate the eyes and skin and affect the central nervous system. Long-term contact may cause allergies, respiratory infections and other health problems, which are greatly limited in practical applications. Summary of the invention

Stir thoroughly with a stirring rod and let it sit for a few minutes to obtain the finished bubble water. The pH value is 5-7.

[0022] Comparative Example 1: In this comparative example, the formula of bubble water includes the following raw materials: sodium dodecylbenzene sulfonate: 1.5 grams; sodium bicarbonate: 0.3 grams; sodium oxalate: 0.5 grams; modified alkyd hydroxyvinyl cellulose: 1.5 grams; polyvinyl alcohol (PVA) 2488: 1 gram; sodium benzoate: 0.04 grams; sodium polyacrylate: 0.02 grams; polyethylene glycol 638 type: 0.2 grams; 6502 type alkyl alcohol amide: 0.5 grams; benzyl ammonium benzoate: 0.01 grams; glucoside: 1 gram; Pour the above-weighed formula directly into 500 ml of water. Stir thoroughly with a stirring rod and let it sit for a few minutes to get the finished bubble water.

[0023] The samples of the above Example 1 and Comparative Example 1 were taken for performance comparison test.

[0024] Compared with Example 1, the formula of Comparative Example 1 lacks sodium α-olefin sulfonate, and the amounts of various raw materials used are different.

[0025] The test project used a bubble wand to blow bubbles for comparison, calculated the number of bubbles (Table 1), and observed the amount of foaming. Although Comparative Example 1 can also blow out a large number of bubbles with a diameter of about 2-5 cm, the bubbles blown out quickly burst in the air, and the number of bubbles existing at the same time is significantly less than that of Example 1. It can be seen that the formula of Example 1 can increase the number of bubbles and prolong the duration of bubbles. The comparison of the number of bubbles of bubble water in Example 1 and Comparative Example 1 is shown in Figure 1 and Figure 2 .

[0026] Table 1: Bubble quantity and duration of bubble water in Example 1 and Comparative Example 1 Foaming quantity Duration (average) Example 1 33~40 1 minute 31 seconds Comparative Example 1 21~29 1 minute 21 seconds

[0027] Comparative Example 2: In this comparative example, the formula of bubble water includes the following raw materials: sodium α-olefin sulfonate: 0.3 g; sodium dodecylbenzene sulfonate: 0.5 g; sodium bicarbonate: 0.7 g; sodium oxalate: 0.4 g; modified alkyd hydroxyethyl cellulose: 2 g; polyvinyl alcohol (PVA) 2488: 0.8 g; sodium benzoate: 0.3 g; sodium polyacrylate: 0.07 g; polyethylene glycol 638 type: 0.2 g; 6502 type alkyl alcohol amide: 0.5 g; benzyl ammonium benzoate: 0.01 g; glucoside: 1 g.

[0028] The preparation method is as follows: In the first step, take 0.3 g of sodium α-olefin sulfonate, 0.5 g of sodium dodecylbenzene sulfonate, 0.7 g of sodium bicarbonate, and 0.4 g of sodium oxalate, and pour them into 500 ml of water. Stir with a stirring rod for 5 minutes; In the second step, pour 2 grams of modified alkyd hydroxyethyl cellulose, 0.8 grams of cold water-soluble polyvinyl alcohol (PVA), 0.3 grams of sodium benzoate, 0.07 grams of sodium polyacrylate, 0.2 grams of polyethylene glycol 638, 0.5 grams of 6502 alkyl alcohol amide, 0.01 grams of benzyl ammonium benzoate and 1 gram of glucoside into the fully dissolved solution in the first step, continue stirring, and let it stand for a few minutes to get the finished bubble water.

[0029] The samples of the above Example 3 and Comparative Example 2 were taken for performance comparison test.

[0030] Compared with Example 3, in the formula of Comparative Example 2, the proportion of sodium lauryl sulfate is reduced, the proportions of sodium bicarbonate and sodium benzoate are increased, and the preparation method is different.

[0031] The test project used a bubble stick to stick bubble water and then waved it outdoors. In the absence of wind or light wind, the length of the bubbles stretched in the air and the number of bubbles formed were observed. Although comparative example 2 can also pull out bubbles, it is obvious that the length of the bubbles stretched in example 3 is longer and the diameter of the bubbles is larger. The comparison of the bubble size of the bubble water in comparative example 2 and example 3 is shown in Figure 2. Figure 3 and Figure 4 .

[0032] Comprehensive evaluation: Embodiments 1 to 3 can all produce bubble water with the expected effect, can all blow out bubbles with large diameters, have a large amount of bubbles, and the bubbles float in the air for a long time.

[0033] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
