Description

Technical Field

[0001] The present invention relates to the technical field of pet cleaning products, and in particular to a pet hair cleaning composition, a preparation method and an application thereof. Background Art

[0002] In recent years, the pet care market has grown rapidly, driven by the growing number of pet owners and rising consumer awareness of pet health and beauty. The concept of pet care has expanded from "cleaning and decontamination" to "health care." Traditional pet care products, primarily focused on basic cleaning, offer limited functionality and unsafe ingredients, failing to meet growing consumer demand.

[0003] The epidermis of dogs' skin is thin, and the skin barrier is fragile, which is easily penetrated by external irritants. The pH of the skin surface is neutral to weakly alkaline (7.0-7.5). However, the neutral environment easily promotes the proliferation of some pathogenic bacteria (such as Staphylococcus, Malassezia) and exogenous pathogens (such as Pseudomonas). In addition, long-term use of irritating cleaning products with strong cleaning power can easily over-strip skin lipids, causing damage to the dog's skin barrier and hair and hair loss, which can easily induce skin diseases such as seborrheic dermatitis.

[0004] Therefore, it is very necessary to develop a compound product that combines the functions of gentle cleansing, barrier repair and hair care. Summary of the Invention

[0005] The main purpose of the present invention is to provide a pet hair cleaning and care composition and its preparation method and application, aiming to solve the problems of existing pet hair products having single functions and high irritation.

[0006] To achieve the above object, the present invention provides a pet hair care composition comprising the following components in percentage by mass:

[0007] 0.5% to 5% plant-derived squalane, 8% to 15% alkyl polyglycoside (APG), 3% to 5% sodium lauroyl sarcosinate, 1% to 5% polyethylene glycol, 1% to 3% emulsifier, 0.2% to 1% tocopherols, 0.1% to 0.8% essential oil, 0.3% to 1% antibacterial mite component, 0.1% to 0.3% preservative, pH regulator, and the balance is deionized water; wherein the alkyl polyglycoside includes at least one of coconut glucoside and decyl glucoside.

[0008] In one embodiment, the molecular weight of the polyethylene glycol is 400-600.

[0009] In one embodiment, the aromatic essential oil includes at least one of camellia essential oil, lemon essential oil, rosemary essential oil and chamomile essential oil.

[0010] In one embodiment, the emulsifier is obtained by mixing Span 80 and Tween 80 in a mass ratio of 3:7.

[0011] In one embodiment, the tocopherols include at least one of α-tocopherol and tocopherol acetate.

[0012] The present invention provides a method for preparing the pet hair cleaning and care composition described in the above technical solution, comprising the following steps:

[0013] S1. Heat deionized water to 60-70° C., then add alkyl polysaccharide, sodium lauroyl sarcosinate and polyethylene glycol in sequence and stir to obtain an aqueous phase mixture;

[0014] S2, mixing the emulsifier, plant-derived squalane, tocopherols, aromatic essential oils and antibacterial mite components, heating to 40-45° C. and stirring to obtain an oil phase mixture;

[0015] S3, cooling the aqueous phase mixture to 40-45° C., then adding the cooled aqueous phase mixture to the oil phase mixture, performing homogenization and emulsification treatment to obtain a premix;

[0016] S4. Adding a pH regulator and a preservative to the premix to obtain the pet hair care composition.

[0017] In one embodiment, in step S1, the stirring speed is 1000-1500 rpm, and the stirring time is 10-15 min; and / or,

[0018] In step S2, the stirring speed is 1000-1500 rpm, and the stirring time is 10-15 min; and / or,

[0019] In step S3, the rotation speed of the homogenization and emulsification treatment is 3000-5000 rpm, and the time of the homogenization and emulsification treatment is 20-30 minutes.

[0020] The present invention provides an application of a pet hair care composition, wherein the pet hair care composition is used for maintaining pet hair, wherein the pet includes a pet dog;

[0021] The pet hair care composition includes the pet hair care composition described in the aforementioned technical solution, or includes the pet hair care composition prepared according to the preparation method of the pet hair care composition described in the aforementioned technical solution.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] In recent years, the pet care market has grown rapidly, driven by the growing number of pet owners and rising consumer awareness of pet health and beauty. The concept of pet care has expanded from "cleaning and decontamination" to "health care." Traditional pet care products, primarily focused on basic cleaning, offer limited functionality and unsafe ingredients, failing to meet growing consumer demand.

[0037] Dogs have a thin epidermis and a fragile skin barrier, making them susceptible to penetration by external irritants. The pH of their skin surface is neutral to slightly alkaline (7.0-7.5). However, this neutral environment easily promotes the proliferation of some pathogenic bacteria (such as Staphylococcus and Malassezia) and exogenous pathogens (such as Pseudomonas). Furthermore, long-term use of strong, irritating cleaning products can over-strip skin lipids, leading to damage to the dog's skin barrier and hair, hair loss, and the development of skin diseases such as seborrheic dermatitis. Therefore, it is essential to develop a comprehensive product that combines gentle cleansing, barrier repair, and hair care.

[0038] Based on the above background, the present invention provides a pet hair care composition comprising the following components in percentage by mass:

[0039] 0.5% to 5% plant-derived squalane, 8% to 15% alkyl polyglycoside (APG), 3% to 5% sodium lauroyl sarcosinate, 1% to 5% polyethylene glycol, 1% to 3% emulsifier, 0.2% to 1% tocopherols, 0.1% to 0.8% essential oil, 0.3% to 1% antibacterial mite component, 0.1% to 0.3% preservative, pH regulator, and the balance is deionized water; wherein the alkyl polyglycoside includes at least one of coconut glucoside and decyl glucoside.

[0040] In the technical solution of the present invention, plant-derived squalane and alkyl polysaccharide are used as core ingredients, and polyethylene glycol and aromatic essential oils are compounded. Plant-derived squalane is milder than animal-derived squalane; the zwitterionic properties of an appropriate amount of alkyl polysaccharide can significantly reduce excessive stripping of pet skin lipids. Compared with traditional petroleum-based surfactants, it is mild, less irritating, non-toxic and harmless, and more friendly to pet skin; sodium lauroyl sarcosinate is compounded with alkyl polysaccharide, which has a good synergistic effect and can improve the defect of poor foaming of alkyl polysaccharide, which is conducive to meeting the demand for efficient cleaning in pet washing and care; aromatic essential oils can add a natural fragrance to the prepared pet hair washing and care composition, while providing a certain softening and nourishing effect on hair. The pet hair washing and care composition provided by the present invention has an excellent moisturizing effect by rationally setting the components and their proportions. It can significantly reduce the amount of water loss of pet dog hair in a dry environment, maintain the softness and luster of the hair, and has the effects of hair care and hair beautification. It is less irritating and can simultaneously achieve the three-in-one "cleaning-repairing-care" effect, simplifying the washing and care process while reducing overall costs.

[0041] It should be noted that the squalane used in the present invention is plant-derived squalane. Squalane has high chemical stability, high affinity to the skin, is not prone to allergic or irritating reactions, and is particularly suitable for pets with sensitive skin; squalane has good moisturizing properties and can form a dense water-locking layer on the epidermis, reducing transepidermal water loss and alleviating dryness and itching. At the same time, it can also form a protective film on the surface of the hair to prevent water evaporation and keep the hair moist and soft. In addition, squalane also has strong antioxidant properties, which can reduce the damage of oxidative stress to the skin and hair by neutralizing free radicals, and has significant advantages in repairing damaged hair scales and improving hair gloss. Plant-derived squalane has the same efficacy as animal-derived squalane, but is safer and more environmentally friendly. In one embodiment of the present invention, the plant-derived squalene used is plant-derived squalene prepared from soybeans, which was purchased from Sea Turtle Life Sciences Co., Ltd.

[0042] It should be noted that alkyl polyglycosides (APG) are a type of non-ionic surfactant formed by the combination of natural sugars (such as glucose) and fatty alcohols through glycosidic bonds. They are highly biodegradable, environmentally friendly and safe, have rich and delicate foam, strong compatibility, are non-toxic and harmless, and have no irritation to the skin. They have a good synergistic effect when used with other surfactants. Although alkyl polyglycosides can replace traditional petroleum-based surfactants, the cost of APG raw materials is higher than that of traditional surfactants, and the foaming properties of APG are difficult to meet the needs of efficient cleaning in pet washing and care, resulting in its less use in actual pet market applications, especially in the washing scenarios of long-haired animals. In addition, not all alkyl polyglycosides can be used in the development of washing products. Alkyl polyglycosides with different carbon chain lengths have different HLB values. In the technical solution of the present invention, the inventors comprehensively considered the HLB value of the alkyl polyglycoside, the type and amount of the added emulsifier, and the washing and care effect of the final product, and selected at least one of coconut oil glucoside and decyl glucoside as the alkyl polyglycoside of the present application, and optimized the amount of the alkyl polyglycoside added, and compounded the alkyl polyglycoside with sodium lauroyl sarcosinate, thereby achieving the goal of ensuring the cleaning power of the washing and care product while also ensuring its mildness and non-irritation, further improving the antistatic effect and moisturizing ability of the prepared pet hair washing and care composition.

[0043] In an embodiment of the present invention, the molecular weight of the polyethylene glycol is 400 to 600. Using polyethylene glycol with a molecular weight of 400 to 600 as a multifunctional solvent and moisturizing regulator can also enhance the compatibility of ingredients, balance moisturizing properties and permeability, and avoid stickiness.

[0044] In an embodiment of the present invention, the aromatic essential oil includes at least one of camellia essential oil, lemon essential oil, rosemary essential oil, and chamomile essential oil. Using aromatic essential oils instead of traditional essences enhances the natural fragrance of the prepared pet hair care composition while also softening and nourishing the hair.

[0045] In an embodiment of the present invention, the emulsifier is prepared by mixing Span 80 and Tween 80 in a mass ratio of 3:7. Considering that the pet hair care product prepared in the present invention is an O / W emulsion, its HLB value depends on the polarity of the oil phase. The HLB value of the oil phase used in the present invention is 12-14. Both Span 80 and Tween 80 are relatively mild emulsifiers. Mixing Span 80 and Tween 80 in a mass ratio of 3:7 can achieve an HLB value of 12-14 for the mixed oil phase, forming a stable emulsion.

[0046] In an embodiment of the present invention, the tocopherols include at least one of α-tocopherol and tocopherol acetate. Tocopherols can improve antioxidant properties. α-tocopherol is the most active of all tocopherol forms, with the highest bioavailability and the strongest antioxidant capacity. Tocopherol acetate is an esterified form of α-tocopherol, which is more stable than pure α-tocopherol.

[0047] In an embodiment of the present invention, the antibacterial mite component is a plant-derived component, and the antibacterial mite component includes at least one of fennel essential oil and tea tree essential oil.

[0048] In an embodiment of the present invention, the preservative includes any one of Genma BP and Genma KL.

[0049] In an embodiment of the present invention, the pH adjuster includes citric acid, which is used to adjust the pH value of the pet hair care composition to 6.5-7.0.

[0050] The present invention provides a method for preparing a pet hair care composition, comprising the following steps:

[0051] S1. Heat deionized water to 60-70° C., then add alkyl polysaccharide, sodium lauroyl sarcosinate and polyethylene glycol in sequence and stir to obtain an aqueous phase mixture;

[0052] S2, mixing the emulsifier, plant-derived squalane, tocopherols, aromatic essential oils and antibacterial mite components, heating to 40-45° C. and stirring to obtain an oil phase mixture;

[0053] S3, cooling the aqueous phase mixture to 40-45° C., then adding the cooled aqueous phase mixture to the oil phase mixture, performing homogenization and emulsification treatment to obtain a premix;

[0054] S4. Adding a pH regulator and a preservative to the premix to obtain the pet hair care composition.

[0055] The technology of the present invention adopts a conventional preparation method to prepare a pet hair care composition, first preparing an aqueous phase mixture and an oil phase mixture separately, then adding the aqueous phase mixture to the oil phase mixture and performing a homogenized emulsification treatment to obtain a dispersed and stable pet hair care composition.

[0056] In an embodiment of the present invention, in step S1, the stirring speed is 1000-1500 rpm, and the stirring time is 10-15 minutes.

[0057] In an embodiment of the present invention, in step S2, the stirring speed is 1000-1500 rpm, and the stirring time is 10-15 minutes.

[0058] In an embodiment of the present invention, in step S3, the rotation speed of the homogenization and emulsification treatment is 3000-5000 rpm, and the time of the homogenization and emulsification treatment is 20-30 minutes.

[0059] The present invention provides an application of a pet hair care composition, wherein the pet hair care composition is used for maintaining pet hair, wherein the pet includes a pet dog;

[0060] The pet hair care composition includes the pet hair care composition described in the aforementioned technical solution, or includes the pet hair care composition prepared according to the preparation method of the pet hair care composition described in the aforementioned technical solution.

[0117] Performance Testing

[0118] 1. The pet hair care compositions of the examples and comparative examples were tested for their care effects, and their hair care and hair beautification and hair brightening effects were evaluated. The specific testing steps are as follows:

[0119] (1) Six pet dogs were selected, including three white Pomeranians and three brown poodles, and randomly divided into two groups, each with three dogs, for a hair washing and care test. The experimental group used Example 7 as an example, and the control group used Comparative Example 1. About 25 mL of the pet hair washing and care composition was used each time;

[0120] (2) Each group of dogs performed step (1) once every 7 days. The dogs were photographed from the front, side, and back before and after the washing and care experiment. The hair condition was scored based on the glossiness, softness, and suppleness of the hair. The scores of each tester were counted and analyzed and summarized. The specific scoring criteria are shown in Table 1. The test results can be found in Figures 1 to 4 .

[0121] Table 1 Sensory scoring criteria

[0122] 1 point 2 points 3 points 4 points 5 points Glossiness matte Dark luster Medium gloss Glossier Obvious gloss Softness hard Harder Medium hardness Softer Very soft Softness Rough Rough medium More supple Very soft

[0123] Figure 1 The following is a statistical chart of sensory scores of hair glossiness using the test group and the control group products. Figure 2 The following is a statistical chart of the sensory scores of hair softness using the test group and the control group products. Figure 3 The following is a statistical chart of the sensory scores of hair smoothness using the test group and the control group products. Figure 4 This is an eye view of the hair condition of pet dogs using the test group and control group products, among which: Figure 4 A is the initial hair condition of the pet dogs in the experimental group, Figure 4 B is the initial hair condition of the pet dogs in the control group. Figure 4 C is the hair condition of the pet dogs in the experimental group after washing and care once. Figure 4 D is the hair condition of the pet dogs in the control group after one washing and care.

[0124] Depend on Figures 1 to 4 It can be seen that the experimental group has significantly improved hair gloss, softness and smoothness compared to the control group, indicating that the addition of plant-derived squalane shampoo and conditioner complex has the effect of beautifying and brightening hair.

[0125] According to the above washing and care test method, the pet dogs in the experimental group and the control group were washed and care for 3 times. The back hair samples of the pet dogs in the initial state and after the third washing and care were taken for electron microscopy. The test results can be found in Figure 5 and Figure 6 .

[0126] Figure 5 The electron microscope images of the hair scales of the experimental group of pet dogs before and after washing and care are shown below. Figure 5 A is an electron microscope image of the hair scales of the experimental group pet dogs in the initial state (magnification ×1K), Figure 5 B is an electron microscope image of the hair scales of the test group pet dogs after washing and care for 3 times (magnification ×1K). Figure 5 C is an electron microscope image of the hair scales of the experimental group pet dogs in the initial state (magnification ×15K), Figure 5 D is an electron microscope image of the hair scales of the test group pet dogs after washing and care for three times (magnification ×15K). Figure 6 The following are electron microscope images of the hair scales of the control group pet dogs before and after washing and care. Figure 6 A is an electron microscope image of the hair scales of the control group pet dogs in their initial state (magnification ×1K). Figure 6 B is an electron microscope image of the hair scales of the control group pet dogs after washing and care for 3 times (magnification ×1K). Figure 6 C is an electron microscope image of the hair scales of the control group pet dogs in the initial state (magnification ×15K), Figure 6 D is an electron microscope image of the hair scales of the pet dogs in the control group after washing and care for three times (magnification ×15K).

[0127] Combine Figure 5 and Figure 6 The test results show that the cuticles in the experimental group were significantly taller and thinner, while the cuticles in the control group showed significant defects, becoming shorter and thicker. These results indicate that hair became smoother and glossier after using the experimental product, suggesting that reducing the amount of plant-derived squalane shampoo and conditioner complex can reduce the effectiveness of hair conditioning and beautifying properties.

[0128] 2. The antistatic effect of the pet hair shampooing and care compositions prepared in Examples 1-7 and Comparative Examples 1-2 was evaluated: the back hair of a healthy Pomeranian long-haired dog was selected as a test sample, and an equal amount of the pet hair shampooing and care compositions of Examples 1-7 and Comparative Examples 1-2 was used to clean the hair for 3 minutes, then rinsed with clean water for 3 minutes and dried in an oven at 30°C for 24 hours. Each group of samples was repeated 3 times in parallel, and the test results were averaged.

[0129] Antistatic testing was conducted according to GB / T 16801 using the surface resistivity method. The resistance value (Δlgρs) was used to evaluate the antistatic performance. The test was conducted at 20°C and a relative humidity of 26%. The results are shown in Table 2.

[0130] Table 2 Antistatic effect test results of Examples 1-7 and Comparative Examples 1-2

[0131] Group △lgρs Example 1 0.88 Example 2 0.86 Example 3 0.83 Example 4 0.82 Example 5 0.85 Example 6 0.83 Example 7 0.81 Comparative Example 1 0.91 Comparative Example 2 0.93

[0132] The results in Table 2 show that the pet hair shampoo and conditioner compositions of Examples 1-7 have a good antistatic effect on pet dog hair; the test results of Examples 1-7 are better than those of Comparative Examples 1-2, indicating that the combination of plant-derived squalane and alkyl polysaccharide in the formula has a certain synergistic effect in exerting the antistatic effect.

[0133] 3. The moisturizing effect of the pet hair shampoo and conditioner compositions prepared in Examples 1-7 was tested by measuring the hair moisture loss to evaluate the moisturizing effect. The smaller the hair moisture loss R, the better the moisturizing ability. The test results are shown in Table 3.

[0134] The back hair of a healthy Pomeranian long-haired dog was selected as a test sample, and the pet hair shampooing and care compositions of Examples 1-7 and Comparative Examples 1-2 were used to clean the hair for 3 minutes, then rinsed with clean water for 3 minutes, and then dried in an oven at 30°C for 24 hours. Each group of samples was repeated 3 times in parallel, and the test results were averaged.

[0135] Place the treated sample in a saturated KCl solution and place it in a drying dish with strictly controlled humidity at 80% for 12 hours, then weigh the mass m1. Then place the sample in a saturated CaCl2 solution and place it in a drying dish with strictly controlled humidity at 26% for 12 hours, then weigh the mass m2. Finally, calculate the moisture loss R, R = (m1-m2) / m1×100%.

[0136] Table 3 Moisturizing effect test results of Examples 1-7 and Comparative Examples 1-2

[0137] Group Hair moisture loss R Example 1 4.7％ Example 2 4.6％ Example 3 4.2％ Example 4 4.1％ Example 5 4.3％ Example 6 4.0％ Example 7 4.0％ Comparative Example 1 5.1％ Comparative Example 2 5.0％

[0138] The test in Table 3 shows that, compared with Comparative Examples 1-2, the pet hair shampooing and care compositions of Examples 1-7 can significantly reduce the amount of water loss of pet dog hair in a dry environment, and have a good moisturizing effect. The moisturizing effect test results of Examples 1-7 are better than those of Comparative Examples 1-2, indicating that the moisturizing effect will be worse when the combination without plant-derived squalane or the combination without alkyl polyglycoside is used.

[0139] 4. The pet hair cleaning and care compositions prepared in Examples 1-7 were subjected to skin irritation tests on different breeds of pet dogs. The test results are shown in Table 4.

[0140] With reference to the human patch test method in the 2015 edition of the "Technical Specification for Safety of Cosmetics", healthy adult dogs of different breeds (Pomeranian, Poodle, Golden Retriever, Beagle) without skin diseases were selected, with 3 dogs of each breed, to test the irritation results of Examples 1-7.

[0141] Table 4 Irritation test results of the pet hair care compositions of Examples 1-7

[0142]

[0143] As shown in Table 4, the pet hair care compositions of Examples 1-7 are relatively mild and have little irritation to the skin of dogs of different breeds, indicating that the pet hair care formula provided in this application is applicable to a variety of dog breeds.
