Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of detergent production, and particularly relates to a dehairing laundry condensation bead capable of preventing static electricity and a preparation method thereof. BACKGROUND

[0002] With the improvement of people's living standards, more and more people will choose to raise pets. Pets, as human companions, are a source of happiness and healthy life for us humans, and through raising pets, people's lives can be healthier and more fulfilling. Through communication with pet dogs, the psychological health of the feeder is improved, and unnecessary pressure in life is reduced, thereby improving work efficiency. However, while bringing people a pleasant mood, it also increases the annoyance of pet hair loss. The large amount of pet hair loss in life is actually very disturbing to people. For example, pet dogs will change their hair in spring, summer and autumn, and if not cleaned in time, the house will be full of hair, and there will be a lot of hair on clothes and beds.

[0003] In daily life, the hair on our clothes is mainly transferred by electronic transfer through frequent friction of clothes with the skin. The clothes will be charged, and the static electricity will attract small objects and will attract pet hair. Through the cationic adsorption of cationic surfactants on clothes, the static electricity generated by friction with clothes can prevent hair from being adsorbed by clothes. Laundry condensation beads, as a product specially designed for machine washing, usually wrap super-concentrated laundry detergent in a water-soluble film. When water is encountered, the water-soluble film dissolves, and the contents are released. Each time, only one laundry condensation bead needs to be put into the washing machine to clean a large number of clothes, and it has the advantages of convenient placement, quantitative packaging, and multi-effect combination. Most of the laundry condensation beads currently use anionic surfactants and nonionic surfactants, and there are few laundry condensation beads containing cationic surfactants. This is because the cationic surfactant has low wettability and dispersibility, often precipitates, and appears turbid precipitate and soft outer film. At the same time, the cationic surfactant also needs to have good compatibility with other ingredients in the contents to ensure that no precipitate appears, thus greatly limiting the application of cationic surfactants in the detergent field. SUMMARY

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the present application provides a dehairing laundry condensation bead capable of preventing static electricity, which effectively overcomes the deficiencies in the prior art.

[0005] The above-mentioned dehairing laundry condensation bead capable of preventing static electricity is composed of a water-soluble outer film and contents.

[0006] The content includes: 5-20wt% of quaternary ammonium salt type cationic surfactant, 20-60wt% of non-ionic surfactant, 10-30wt% of alkyl polyglycoside surfactant, 1-10wt% of amino modified polyethylene glycol, 15-30wt% of solvent, 1-15wt% of auxiliary agent, and the balance of deionized water.

[0007] The preparation raw material of the quaternary ammonium salt type cationic surfactant includes 6-10 parts of diethylenetriamine, 8-12 parts of triethylenetetramine, 10-15 parts of hydroxyethyl ethylenediamine, 50-80 parts of stearic acid, and 3-5 parts of quaternary amine agent.

[0008] The amino modified polyethylene glycol has the following general formula:

[0009]

[0010] Wherein, n is 3-8;

[0011] The alkyl polyglycoside surfactant is selected from alkyl polyglycoside with 6-10 hydrophobic chain carbons. The alkyl polyglycoside with 6-10 hydrophobic chain carbons has the excellent performance of low irritancy, non-toxicity and complete biodegradability. When the alkyl polyglycoside surfactant has a lower hydrophobic chain carbon number, its dirt removal capacity is poor, and when the alkyl polyglycoside surfactant has a higher hydrophobic chain carbon number, its water solubility and wetting property are poor. Therefore, the alkyl polyglycoside with 6-10 hydrophobic chain carbons is selected, which has good water solubility and skin affinity, produces less foam, can effectively reduce the number of rinsing, improve the rinsing efficiency, and is easy to be compounded with other surfactants and has good compatibility.

[0012] Further, the solvent is selected from one or more combinations of glycerol, propylene glycol, ethylene glycol, sorbitol, diethylene glycol, and polyethylene glycol.

[0013] Further, the non-ionic surfactant is selected from one or more combinations of secondary alcohol polyoxyethylene ether, fatty alcohol polyoxyethylene ether, isomeric alcohol ether polyoxyethylene ether, and fatty acid methyl ester ethoxylate.

[0014] Further, the auxiliary agent is selected from at least one of chelating agent, solubilizing agent, biological complex enzyme, stabilizer, enzyme preparation, essence, preservative, and pigment.

[0015] Further, the solubilizing agent is selected from one or more combinations of sodium xylene sulfonate, potassium citrate, sodium citrate, ethanol, and urea.

[0016] Further, the deionized water accounts for ≥10% of the weight of the content.

[0017] Another object of the present application is to provide a preparation method of the anti-static unhairing and washing laundry condensing bead, which comprises the following steps:

[0018] S1. mixing diethylene triamine, triethylene tetramine, hydroxyethyl ethylene diamine and stearic acid, stirring, adding water carrying agent, stirring again, heating reaction. Removing unreacted substances, then performing cyclization reaction to obtain stearic imidazoline;

[0019] S2. adding quaternary ammonium agent to the stearic imidazoline, reacting to obtain quaternary ammonium salt type cationic surfactant;

[0020] S3. mixing solvent, amino-modified polyethylene glycol, non-ionic surfactant, alkyl polyglycoside surfactant and quaternary ammonium salt type cationic surfactant, stirring uniformly;

[0021] S4. adjusting pH value, after physical and chemical indexes are qualified, adding auxiliary agent, mixing and stirring uniformly, supplementing deionized water, filtering and discharging, using water-soluble film to perform encapsulation to obtain the product.

[0022] Further, in step S1, the temperature of the heating reaction is 140-160℃, and the time is 4-6h.

[0023] Further, in step S1, the temperature of the cyclization reaction is 220-250℃, and the time is 4-6h.

[0024] Further, in step S1, the water carrying agent is selected from xylene.

[0025] Further, in step S4, the water-soluble film is polyvinyl alcohol film with a thickness of 60-100μm.

[0026] The present application has the following beneficial effects:

[0027] The anti-static dehairing laundry condensation beads of the present application have good synergistic enhancement effect by compounding quaternary ammonium salt type cationic surfactant, amino modified polyethylene glycol and short carbon chain alkyl glycoside surfactant, greatly enhancing the solubility and dispersibility of quaternary ammonium salt type cationic in the content, and making the surfactants have good affinity, the laundry condensation beads can keep transparent, clear, uniform and no stratification in water for a long time. The quaternary ammonium salt type cationic surfactant in the present application is obtained by mixing specific proportions of hydroxyethyl ethylenediamine, diethylenetriamine, triethylenetetramine and stearic acid, then adding quaternary ammonium salt type cationic surfactant, which can well finish the fabric fibers, form an antistatic layer on the surface of the fabric, and has good antistatic effect and soft hand feeling after washing. After adding a certain proportion of amino modified polyethylene glycol and short carbon chain alkyl glycoside surfactant, the amino modified polyethylene glycol has ether group, amino and hydroxyl group, good wetting and solubility, and the amino has strong polarity and adsorption capacity, good compatibility with quaternary ammonium salt type cationic surfactant, strong solubilization and synergistic effect. At the same time, the hydrophobic chain segment of quaternary ammonium salt type cationic surfactant and alkyl glycoside surfactant can well block the penetration of the hydrophilic group of amino modified polyethylene glycol and other contents to the water-soluble film, and the short carbon chain alkyl glycoside surfactant has good compatibility with other surfactants, further improving the stability of the laundry condensation beads as a whole.

[0047] Comparative Example 1

[0048] The laundry condensation beads in Comparative Example 1 are the same as Example 1 in terms of ingredients and preparation method, and the biggest difference is that the laundry condensation beads in Comparative Example 1 do not contain amino-modified polyethylene glycol.

[0049] Comparative Example 2

[0053] Test Example 1

[0054] The laundry condensation beads of Examples 1-3 and Comparative Examples 1-3 were tested for stability, and the specific testing method was as follows:

[0055] Test of low-temperature stability: The laundry condensation beads were placed in an environment with a temperature of 0±2℃, and after constant temperature for 2 months, the appearance stability of the laundry condensation beads was observed, and whether there was obvious discoloration, stratification or precipitation was observed. If the appearance was full, there was no obvious discoloration, stratification or precipitation, it was determined that the low-temperature stability was qualified.

[0056] Test of room temperature stability: The laundry condensation beads were placed in an environment with a temperature of 25±2℃, and after constant temperature for 2 months, the appearance stability of the laundry condensation beads was observed, and whether there was obvious discoloration, stratification or precipitation was observed.

[0058] The stability test results of Examples 1-3 and Comparative Examples 1-3 are shown in Table 2.

[0059] Table 2. Stability test results of laundry condensation beads of Examples 1-3 and Comparative Examples 1-3

[0060]

[0061] From the stability test results of Table 2, it can be seen that the laundry beads of Examples 1-3 can ensure the stability of the samples at each test temperature, the appearance of the beads is full and hard, and the content flows uniformly, while the laundry beads of Comparative Examples 1-3 all have different degrees of performance decline. Comparative Example 1 has no amino-modified polyethylene glycol added, and the concentration of surfactant in the laundry beads is too high, so precipitation occurs. Comparative Example 2 has no alkyl polyglycoside surfactant added, and at low temperature, the stability of the laundry beads is not as good as that of the examples, and at high temperature, the PVA film encapsulated by the laundry beads becomes soft; Comparative Example 3 has no quaternary ammonium salt type cationic surfactant added, although the stability at low temperature is good, but at room temperature and high temperature, the PVA film encapsulated by the laundry beads becomes soft.

[0062] Test Example 2

[0063] The polyester fabric washed by the laundry beads of Examples 1 and Comparative Examples 2-3 was subjected to antistatic testing, the test method referring to the standard GB / T 16801 "Determination of antistatic property of fabric conditioner", the test solution concentration being 10.0 g / L, the test solution soaking the treated polyester fabric piece for 10 min, the soaked fabric piece being dried and subjected to constant temperature treatment according to the standard GB / T 16801, and finally using a high resistance meter to test the surface resistance of the fabric piece, and calculating the logarithmic value reduction of the surface specific resistance of the polyester fabric piece before and after soaking according to the formula, the test results being shown in Table 3.

[0065] Sample Name Surface Resistivity Log Value Reduction (Δlgρs) Standard laundry liquid 3.91 Example 1 6.25 Comparative Example 2 5.58 Comparative Example 3 4.02

[0066] The standard laundry liquid in Table 3 is the standard laundry liquid specified in Appendix B of GB / T 13174, which is purchased from Taiyuan Institute of Daily Chemicals.

[0067] From Table 3, it can be seen that the antistatic effect of the laundry beads of Example 1 after adding the quaternary ammonium salt type cationic surfactant is obviously better than that of the standard laundry liquid and the laundry beads of Comparative Example 3. It is proved that the quaternary ammonium salt type cationic surfactant added to the laundry beads can effectively neutralize the static charge on the fabric and enhance its antistatic property during the washing process.

[0068] Test Example 3

[0069] The pet hair removal performance test was carried out on the laundry condensation beads of Example 1 and Comparative Examples 2-3. The specific test method was as follows: 0.1000 g of pet hair (preferably long dog hair or cat hair) was evenly applied to a pure cotton black T-shirt, 1 laundry condensation bead was added, and the treated T-shirt was subjected to a standard washing program in a drum washing machine. After washing, the T-shirt was placed in a dry place to dry for 24 h, then the hair on the T-shirt was removed with tweezers and weighed, and the calculation was made. The hair removal rate calculation formula: removal rate (%) = (total weight of hair before washing - total weight of hair after washing) / total weight of hair before washing x 100%

[0070] Table 4 Test results of cat hair removal of the detergent compositions of Example 1 and Comparative Examples 2-3

[0071]

[0072]

[0073] As can be seen from Table 4, the hair removal effect of the laundry condensation beads of Example 1 after adding quaternary ammonium salt type cationic surfactant is obviously better than that of the standard laundry liquid and the laundry condensation beads of Comparative Example 3. It is proved that without adding quaternary ammonium salt type cationic surfactant in the laundry condensation beads, the hair removal rate is comparable to that of the standard laundry liquid, and there is almost no obvious effect. After adding quaternary ammonium salt type cationic surfactant, the antistatic property of the fabric after washing can be effectively increased, and the adsorption of the fabric to the hair can be reduced.
