Description

Technical Field

[0001] The invention relates to the technical field of detergents, and in particular to fragrance beads and a preparation method thereof. Background Art

[0002] With the improvement of people's living standards, washing clothes is no longer just a basic cleaning. Leaving fragrance on clothes is a fashion and a way to solve many embarrassing problems in some occasions. For example, some specific occasions will produce special odors, such as the smell of fireworks in hot pot and barbecue, the smell of sweat after intense exercise, and the musty smell produced in a humid environment. Aerosols containing these special odors adsorbed on clothes will produce unpleasant feelings. If clothes can emit fragrance for a long time, it can cover and dilute the above odors. Therefore, a product that can make clothes emit pleasant fragrance for a long time after washing is very important for modern life.

[0003] A certain amount of fragrance is usually added to existing washing products such as laundry detergent, laundry tablets, laundry soap and softener to give the products a certain fragrance. The washed clothes also have a certain fragrance, but the fragrance cannot be retained for a long time. When dried naturally, the fragrance lasts for one day. If dried and exposed to the sun, the fragrance retention time is even shorter. This is because the main function of the above-mentioned laundry detergent, laundry tablets, laundry soap and other products is to remove stains, and the fragrance is only an additional function. During the washing process, most of the fragrance in this type of washing product is discharged from the washing machine with the rinse water after 1 to 3 rinses. Therefore, the fragrance retention effect on the clothes is not strong; and the popularity of softeners is not high, and they are mainly for fabrics such as cotton and wool, so there are certain limitations in their use. In addition, most people will choose to spray perfume to add fragrance to their clothes, but fragrance is a volatile substance, and it is difficult for perfume to achieve a lasting effect.

[0004] At present, a low-cost and efficient clothing fragrance bead is disclosed in the Chinese document CN109652215A, and the raw materials include: 50-60 parts of polyethylene glycol, 25-35 parts of calcium stearoyl lactylate, 10-20 parts of inorganic salt, 0.3-1 parts of essence microcapsules and 1-3 parts of essence. The principle of achieving long-lasting fragrance of the fragrance beads disclosed in the Chinese document is: by adding calcium stearoyl lactylate to control the dissolution rate of the fragrance beads in water, the essence wrapped in the fragrance beads can be slowly released during the laundry process, and the fragrance is prevented from being discharged from the washing machine in large quantities during the washing and rinsing process, so that the fragrance is more effectively attached to the clothes for a longer time, and the fragrance is more durable. It can be known from the text records and experimental data of the Chinese document that when the dissolution efficiency of the fragrance beads is improved, that is, when the dissolution time of the fragrance beads is reduced, the fragrance durability of the fragrance beads on the clothes will be reduced at the same time. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the fragrance beads in the prior art cannot maintain a longer fragrance effect with a shorter dissolution time, thereby providing a fragrance bead with a shorter dissolution time and a longer fragrance effect and a preparation method thereof.

[0006] A fragrance bead comprises the following raw materials in parts by weight:

[0007] 40-50 parts of polyethylene glycol, 20-30 parts of water-soluble inorganic compound, 5-15 parts of modified starch, 0.5-3 parts of flavor microcapsule and 1-2 parts of flavor;

[0008] The modified starch includes sodium carboxymethyl starch and oxidized starch.

[0009] The mass ratio of the sodium carboxymethyl starch to the oxidized starch is 1:1-2.

[0010] The raw materials of the fragrance beads of the present invention also include 0.2 to 1 part of microsphere foaming agent.

[0011] The water-soluble inorganic compound is sodium bicarbonate and / or sodium sulfate.

[0012] When the water-soluble inorganic compound is sodium bicarbonate and sodium sulfate, the mass ratio of sodium bicarbonate to sodium sulfate is 1:1.

[0013] The melting point of the polyethylene glycol is in the range of 65-70°C.

[0014] The polyethylene glycol is polyethylene glycol 6000.

[0015] Comprise the following raw materials by weight:

[0016] 36 parts of polyethylene glycol, 28 parts of water-soluble inorganic compound, 12 parts of modified starch, 0.8 parts of microsphere foaming agent, 2.4 parts of flavor microcapsule and 1.6 parts of flavor.

[0017] A method for preparing fragrance beads, comprising:

[0018] S1. Preheat polyethylene glycol in a heating pot and melt it at 65°C to 70°C to form a viscous liquid;

[0019] S2, adding a formulated amount of a water-soluble inorganic compound to the viscous liquid, stirring to uniformly disperse the inorganic compound, then adding a formulated amount of modified starch, and finally adding flavor microcapsules and flavor to form a preparation liquid;

[0020] S3, packaging the prepared liquid, and then cooling it to obtain the clothing fragrance beads.

[0021] In the step S2, after adding the modified starch in the formula amount, the temperature is raised to 100° C., and then the microsphere foaming agent in the formula amount is added, and the temperature is maintained for 5 minutes. Finally, the flavor microcapsules and flavor are added to form a preparation liquid.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The modified starch used in the raw material of the fragrance beads provided by the present invention improves the adhesion of the essence microcapsules to the fibers, that is, the modified starch in the present invention is selected as water-soluble sodium carboxymethyl starch and oxidized starch. Among them, sodium carboxymethyl starch has a coating effect on the essence. When it acts with the essence in the polyethylene glycol medium, it can coat the essence, reduce the volatilization of the essence during processing, swell and disintegrate when it encounters water during washing, accelerate the dissolution of the fragrance beads, and evenly disperse in the water after dissolution, and slowly release the essence wrapped in sodium carboxymethyl starch; oxidized starch is a sizing agent for textiles, has good adhesion to the fabric fibers, and at the same time adsorbs the sodium carboxymethyl starch coated with the essence, so that the essence is combined with the fabric fibers. When the above two substances are used in combination, the fragrance beads can be dissolved more quickly in water, and the essence can be better attached to the surface of the fabric fibers after the fragrance beads are dissolved, so that it can be slowly released at a certain speed, thereby achieving the purpose of making the essence more long-lasting and effective to attach to the clothes, with the advantages of fast dissolution and lasting fragrance.

[0024] At the same time, the amount of modified starch is further limited to 5-15 parts by weight in the present invention. When the amount of modified starch is higher than 15 parts by weight, the melting fluidity of polyethylene glycol will be reduced, resulting in processing difficulties and increased costs; and when it is lower than 5 parts by weight, the flavor is not completely coated and the adhesion effect is reduced. The present invention further limits the amount of modified starch, which can not only meet the requirements of long-lasting fragrance retention and rapid dissolution, but also effectively reduce costs, facilitate preparation and processing, and have better effects.

[0025] 2. The raw materials of the present invention also include a microsphere foaming agent. The role of the microsphere foaming agent used in the present invention is to reduce the density of the fragrance beads by using the microsphere foaming agent. The selection of the amount of the microsphere foaming agent can make the density of the fragrance beads close to 1, thereby meeting the requirement of being suspended in water, so that the fragrance beads are suspended in water during washing, thereby enhancing the combination of fragrance and clothing and prolonging the fragrance retention time.

[0026] 3. In the present invention, the melting point range of polyethylene glycol is limited to between 65 and 70°C, and polyethylene glycol 6000 is further preferred. It not only has better fluidity, but also facilitates the processing of fragrance beads and reduces the difficulty of processing and preparation; at the same time, it can also enable the manufactured product to withstand high environmental temperatures, without adhesion and deformation, and has stronger versatility.

[0027] 4. The water-soluble inorganic compound in the present invention is preferably sodium bicarbonate and / or sodium sulfate, wherein sodium bicarbonate and sodium sulfate can dissolve rapidly in water, leaving no residue on clothing, and can also be evenly dispersed in melted polyethylene glycol without suspension and sedimentation. Sodium bicarbonate can accelerate the dissolution rate of the fragrance beads, and sodium sulfate can effectively improve the hardness of the fragrance beads, prevent extrusion and collision, and produce broken pieces. The amount of the water-soluble inorganic compound in the present invention is preferably higher than 20 parts by weight, which can effectively reduce production costs. At the same time, the amount of the water-soluble inorganic compound is preferably lower than 30 parts by weight, which can effectively avoid the influence on fluidity during processing, reduce processing difficulty, and make molding easier.

[0028] 5. The present invention also provides a preparation process of the fragrance beads, through which the fragrance beads of the present invention can be simply and effectively prepared, and the operation is simple. DETAILED DESCRIPTION

[0060] Test example

[0061] 1. Dissolution rate test

[0062] Take the clothing fragrance beads prepared in Examples 1 to 6 and Comparative Example 1 respectively, with a diameter of 1 cm, and dissolve them in water of the same volume (water addition amount 300 ml / g) and temperature 10°C, leave them naturally, and press the stopwatch to start timing, observe the dissolution of the fragrance beads, press the stopwatch to stop timing when the fragrance beads are completely dissolved, and record the dissolution time of the fragrance beads. The results are shown in Table 1.

[0063] Table 1

[0064]

[0065] 2. Fragrance durability test

[0066] The same clothes (5 kg shirts) were placed in the same washing machine and the same volume of water was added, and the same washing program was set (drum washing machine washing 6L water 15min, dehydration 3min, rinsing 10L water 12min, rinsing 3 times), and then the clothing fragrance beads (20g) of Examples 1 to 6 and Comparative Example 1 were added, washed for the same time and dried in the same environment and conditions, and then the clothes were placed in a sealed box with two small holes at a temperature of 25°C to evaluate their fragrance persistence. The test results are shown in Table 2 below.

[0067] Table 2

[0068] Example 1 After 97 days, there is basically no fragrance Example 2 After 95 days, there is basically no fragrance Example 3 After 80 days, there is basically no fragrance Example 4 After 78 days, there is basically no fragrance Example 5 After 90 days, there is basically no fragrance Example 6 After 92 days, there is basically no fragrance Comparative Example 1 After 78 days, there is basically no fragrance

[0069] Usually, the washing time of a washing machine is generally 15 minutes, and the rinsing and dehydration time is 45 minutes. As shown in Table 1, the clothing fragrance beads prepared in Examples 1, 3, 4, 5, and 6 of the present invention have a suitable time for complete dissolution, which is basically consistent with the time it takes for a washing machine to wash clothes. Among them, the inorganic water-soluble compounds in Examples 3, 4, and 5 are increased, the cost is reduced, the dissolution time is shortened, and the processing difficulty is increased. When the washing machine enters the rinsing program in Example 2, there are still undissolved residues, which will affect the fragrance effect. Its fragrance time is 2 days shorter than that of Example 1. As shown in Table 2, the modified starch in Examples 3 and 4 is reduced, and the fragrance time is shortened. The dissolution time and fragrance time of Examples 1 and 6 are better than those of other examples and comparative examples, but the fragrance time of Example 6 is 5 days shorter than that of Example 1 due to the absence of a microsphere foaming agent.

[0070] It can be seen from the comprehensive data in Tables 1 and 2 above that the change in the formula of the present invention can not only greatly reduce the dissolution time of the fragrance beads, but also, under a shorter dissolution time, the fragrance in the present invention can better adhere to the clothes, greatly prolonging the fragrance retention time, and the effect is very significant.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
