Description

Fabric cleaning composition for pet hair removal TECHNICAL FIELD

[0001] The present application belongs to the technical field of cleaning agents, and particularly relates to a fabric cleaning composition for pet hair removal. BACKGROUND

[0002] With the increasing number of pet owners in China, how to solve the problem of pet hair sticking to clothes / fabrics has become increasingly prominent. Cats and dogs, etc. have a layer of oil on the surface of their hair due to low bathing frequency. Pet hair is prone to static charge and usually has a negative charge. Strong electrostatic interaction occurs when it comes into contact with clothes / fabrics, and it can stick to clothes / fabrics relatively stably. Ordinary laundry detergent usually mainly uses negatively charged anionic surfactants, which are difficult to effectively eliminate the static effect carried by the hair during the washing process, and cannot effectively clean and remove the hair on the surface of the clothes / fabrics. Consumers have to use other methods, such as adhesive rollers, to manually remove the hair.

[0003] The existing household cleaning and care solution has many cleaning products that use cationic surfactants / cationic polymers in combination with anionic surfactants for the cleaning and softening of clothes to achieve dual or multiple effects. For example, CN202010288186 discloses a composition comprising 0.1-20% imidazolinium salt, 0.5-40% fatty acid potassium salt (anion), 1-50% alcohol solvent, and the remaining amount of other components. The composition has both washing and softening functions, and can still provide softening effect for fabrics after going through the entire washing and rinsing process, so that washing and softening can be completed in only one step, which is convenient to use.

[0004] In addition, CN202211457124.3 discloses a liquid detergent with softening function, comprising the following components by weight percentage: 0.2-3% cationic polymer, 0.2-3% hydrophilic modified silicone oil, 5-65% surfactant composition, 0.2-5% washing aid, and the balance is solvent; the hydrophilic modified silicone oil is amino-modified or polyether-modified silicone oil; the liquid detergent has significant softening effect and good stain removal effect, and can realize the functions of softening and washing in one.

[0005] The existing cleaning products focus on the conditioning and softening of clothes during the washing process without affecting the cleaning ability. No special attention is paid to how to eliminate static electricity on a large scale and effectively remove the hair sticking to the surface of the clothes.

[0006] In order to eliminate the negative charge of the hair, the formula often needs to introduce a positively charged cationic substance. The electrostatic neutralization of positive and negative charges can eliminate or eliminate the adhesion ability of the hair to the fabric. During the laundry process, the laundry liquid is highly diluted, usually diluted by more than 100 times, and a certain concentration of cationic substances in the product is needed to effectively neutralize and remove the surface charge of the hair during the washing process. The high cleaning ingredients in the laundry liquid are negatively charged anionic surfactants, and other nonionic / amphoteric surfactants are compounded. During the dilution process of the product itself or the product, the anions and cations are prone to react and flocculate. This process reduces the cleaning performance of the anionic surfactant, and more importantly, it reduces the neutralization and elimination of the positive charge on the hair by the cationic substance, and reduces the hair removal effect of the product. During use, flocculation is also very easy to wrap the washed stains, forming secondary deposition and causing secondary pollution. SUMMARY

[0007] The purpose of the present application is to provide a fabric cleaning composition for removing pet hair, which can effectively eliminate static electricity and remove hair from fabric while maintaining cleaning ability, and limit the charge interaction between anions and cations to maintain good stability of the product during dilution and use.

BRIEF DESCRIPTION OF DRAWINGS

[0026] Figure 1 is a photo of the cleaning composition without antagonistic flocculation phenomenon in the stability (flocculation study) test of Example 2;

[0027] Figure 2 is a photo of the cleaning composition with antagonistic flocculation phenomenon in the stability (flocculation study) test of Example 2. DETAILED DESCRIPTION

[0028] The technical solutions of the present application are further described in detail below in combination with specific examples, which are intended to better understand the essence and characteristics of the present application, and are not a limitation on the scope of protection.

[0029] The pet hair removing fabric cleaning composition of the present application is a stable, high cationic surfactant content, and high decontamination power detergent composition, which can efficiently remove pet hair adhered to clothes and has the function of preventing pet hair from re-adhering to fabric. The composition selects high steric hindrance cationic surfactant with positive charge, adjusts the combination and proportion of anionic surfactant with negative charge and amphoteric surfactant with partial negative charge, and limits the charge interaction between anions and cations. In addition, by adjusting the pH value and balancing the ionic charge intensity, the direct interaction between positive and negative charges is further limited, so as to ensure the stability of the product during storage and use, and during high dilution process, to ensure the high cleaning power of conventional stains and effectively remove pet hair on clothes.

[0030] As described above, the pet hair removing fabric cleaning composition contains high steric hindrance cationic surfactant with a content of 0.5-10%, 2-60% of amphoteric surfactant, 0.5-8% of anionic surfactant, and the rest is water. The ratio of cationic surfactant to anionic surfactant is about 20:1 to 1:8, and the product pH is between 6.0 and 10. A solvent or other functional components can also be included.

[0031] In the cleaning composition, the cationic surfactant is neutralized by the electrostatic interaction of positive and negative charges to eliminate the adhesion of the hair to the fabric. The anionic surfactant, compounded with the zwitterionic surfactant, nonionic surfactant, mainly plays a cleaning role. Due to the presence of a large amount of anionic surfactant, the cationic and anionic surfactants are prone to flocculation, which reduces the cleaning performance of the anionic surfactant, and reduces the elimination of the negative charge on the hair by the cationic surfactant, and reduces the hair removal effect. For the composition of the present application, it is necessary to first maintain the cleaning ability of the composition, and at the same time, sufficient cations can effectively eliminate static electricity and remove hair on the fabric. On the other hand, the charge interaction between the anion and the cation is limited, and the anion and the cation are stably coexisted in the same system for a long time. In dilution and use, the product maintains good stability. Therefore, the performance of the composition needs to meet the requirements and maintain a balance in the three aspects of hair removal rate, detergency and product stability.

[0032] In the following examples, the performance test method of the composition is as follows:

[0033] 1. Stability (flocculation study) test

[0034] 5.0 grams of the cleaning composition was diluted with deionized distilled water, respectively 10 times, 50 times, 100 times (to simulate the change of water amount under different washing conditions and during the washing process), and placed for a certain time. Observe whether there is a stratification phenomenon, or whether there is a flocculation or precipitation.

[0035] 2. Efficacy test method I: hair removal effect test

[0036] (1) Take a commercially available Uniqlo black pure cotton T-shirt, evenly spread 0.30g of the collected Viverricola hair on the front and back of the T-shirt, and carefully count the number of hairs;

[0037] (2) Laundry washing: put the pre-treated T-shirt with hair stains into a pulsator washing machine (Haier, EB60M9), and add 6 pieces of laundry at the same time. Set the water amount to 46L (tap water), add 30ml of laundry detergent, soak for 10 minutes, and wash for 30 minutes. Rinse twice, and take out after spinning. Spread the black T-shirt and count the remaining hair.

[0038] (3) Repeat the above experiment using different laundry detergents.

[0039] Calculate the hair removal effect of the laundry detergent, and the test result is expressed by the removal rate: removal rate = (number of hairs adhered to the laundry before washing - number of hairs adhered to the laundry after washing) / number of hairs adhered to the laundry before washing * 100%

[0040] 3. Efficacy test method II: cleaning detergency test

[0041] The detergency test uses vertical detergency machine, referring to the relevant standards of GB / T 13174-2003 Detergency Value Test of Laundry Detergent in the Standard Compilation of Surfactants and Detergent Products 2005. The details are as follows:

[0042] • Standard national standard dirt cloth category: JB01 (carbon black oily dirt cloth) JB02 (protein dirt cloth) JB03 (sebum dirt cloth)

[0043] • Dirt cloth size: 6 cm diameter disc

[0044] • Dirt cloth quantity: 3 pieces of each, a total of 9 pieces per group

[0045] • Test instrument: RHLQ vertical detergency machine

[0046] • Test parameters: temperature: 30 ± 0.5 ℃, rotation speed: 120 rpm, time: 20 min, hard water concentration 250 ppm, hard water volume 1 L / cylinder, rinsing time: 30 s, drying method: natural flat drying.

[0047] For different national standard dirt cloths, the whiteness values before and after washing are measured, and the difference is determined as the detergency value of the test product to the dirt cloth. For the selected dirt cloth, compare its detergency value with that of the corresponding standard washing product, and calculate the ratio as the detergency of the test product to the dirt cloth. The larger the ratio, the better the washing effect.

[0048] Detergency = test product detergency value / standard washing product detergency value

[0049] = (whiteness value before washing - whiteness value after washing) 测试产品 / (whiteness value before washing - whiteness value after washing) 标准洗涤产品 .

[0050] Preferably, the fabric cleaning composition comprises 1.50-8% cationic surfactant, 3-40% amphoteric surfactant, 1-8% nonionic surfactant, 1-6% anionic surfactant, and the ratio of cationic surfactant to anionic surfactant is between 15:1 and 1:6.

[0051] Example 1

[0052] A fabric cleaning composition for removing pet hair, comprising the following components in weight percentage:

[0053] The pH of the composition is 7.03. The product is stable and clear and transparent at 40°C / 75% RH and at room temperature for 1 week. The product is stable and no abnormal precipitation occurs when diluted with deionized water at 10 / 50 / 100 times. The hair removal rate of the product is 96% (48% for the national standard laundry detergent) according to the above hair removal test method. The cleaning and stain removal power is tested according to the above method. The stain removal power for carbon black stained cloth is 1.15, the stain removal power for protein stained cloth is 2.80, and the stain removal power for sebum stained cloth is 1.50 compared with the national standard laundry detergent.

[0055] The fabric cleaning compositions are prepared according to Table 1 below, and the hair removal effect and cleaning and stain removal power tests are carried out, and the results are as follows:

[0056] Table 1

[0057] The stability (flocculation study) test simulates the normal laundry process, and the cleaning composition is added to deionized water to observe whether the positive and negative charges of the cationic surfactant and the anionic surfactant neutralize each other, and whether the flocculation reaction occurs to precipitate from the solution. Figure 1 shows the phenomenon observed in Example 2-4, and no antagonistic flocculation reaction occurs, and the solution remains clear and transparent; Comparative Example 1 and Comparative Example 2 will undergo antagonistic flocculation, and form flocculation material, as shown in Figure 2.

[0058] The content of anionic surfactant in the composition of Comparative Example 1 is relatively high, and the ratio of cationic surfactant to anionic surfactant is too low, and the product stability is poor; although the content of anionic surfactant is reduced and the ratio of cationic surfactant to anionic surfactant is increased in Comparative Example 2, the flocculation reaction still occurs easily because the steric hindrance of the cationic surfactant is low.
