Description

Technical Field

[0001] This invention relates to the field of pet grooming products, specifically to an anti-hair loss pet grooming gel composition and its preparation method. Background Technology

[0002] With the continuous improvement of living standards, the number of pets kept in households is constantly increasing. Because pets mostly have thick fur and like to roam and roll in grass and mud, they easily carry and breed pathogens such as mosquitoes, lice, fleas, and mites. Combined with their body odor, they easily accumulate various bacteria, posing a significant health risk to both pets and their owners. Therefore, pet cleaning not only involves removing dust and dirt from their fur but also achieving the goals of parasite control, odor removal, and antibacterial and bacteriostatic effects. Thus, pet hygiene has always been a major concern. Existing technology has developed various types of pet shampoos, but often, during washing, it is necessary to apply the shampoo and rub it for a long time to enhance its cleaning power, and this can also lead to significant hair loss during washing. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an anti-hair loss pet shampoo and conditioner gel composition and its preparation method.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an anti-hair loss pet shampoo and conditioner composition, wherein the anti-hair loss pet shampoo and conditioner gel composition comprises the following components in weight percentage: 8%–12% octyldodecanool, 1%–4% PEG-40 hydrogenated castor oil, 2%–4% glycerol, 3%–5% maleic anhydride-styrene-methylpropenesulfonate sodium polymer, 5%–10% ginkgo biloba extract, 0.3%–1% nicotinamide, 0.3%–0.8% vitamin E, 0.1%–0.5% aromatic essential oil, 0.1%–0.25% antibacterial and anti-mite components, pH adjuster, and the balance being deionized water.

[0005] In the aforementioned anti-hair loss pet shampoo and conditioner composition, octyldodecaneol, hydrogenated castor oil, glycerol, and maleic anhydride-styrene-methylpropenesulfonate sodium polymer, with octyldodecaneol as the main oil phase, are mixed and homogenized with hydrogenated castor oil, glycerol, and maleic anhydride-styrene-methylpropenesulfonate sodium polymer as the main surfactant to form a microemulsion system. The microemulsion is uniform and transparent, capable of loading effective ingredients such as ginkgo leaf extract, niacinamide, vitamin E, aromatic essential oils, and antibacterial and anti-mite components. The microemulsion loaded with effective ingredients is dispersed in an aqueous system, with an average particle size of 20- With a particle size of 80nm and a polydispersity index (PDI) below 0.3, the microemulsion has a uniform particle size. As an anti-hair loss pet shampoo composition, when gently applied to the pet's body, the small and uniform microemulsion particles can be better and more evenly distributed on the pet's body surface. Moreover, the microemulsion can dissolve oil, sugars, proteins, etc. on the pet's body surface, achieving a cleaning effect. Furthermore, the small and uniform microemulsion particles provide good cleaning effect with direct rinsing, leaving no residue. This avoids the need for repeated rubbing when using pet shampoo, reducing discomfort and hair loss for the pet.

In the anti-hair loss pet shampoo and conditioner composition of this invention, octyldodecaneol, hydrogenated castor oil, glycerol, and maleic anhydride-styrene-methylpropenesulfonate sodium polymer, with octyldodecaneol as the main oil phase, are mixed and homogenized with hydrogenated castor oil, glycerol, and maleic anhydride-styrene-methylpropenesulfonate sodium polymer as the main surfactant to form a microemulsion system. The microemulsion oil is uniform and transparent, and can load effective ingredients such as ginkgo leaf extract, nicotinamide, vitamin E, aromatic essential oils, and antibacterial and anti-mite components. The microemulsion oil is dispersed in an aqueous system with an average particle size of 20-80 nm and a polydispersity index (PDI) of less than 0.3. The microemulsion particles are uniform in size. As an anti-hair loss pet shampoo composition, this anti-hair loss pet shampoo composition is gently applied to the pet's body. Due to the small and uniform size of the microemulsion particles, it can be better and more evenly distributed on the pet's body surface. Moreover, the microemulsion can dissolve oil, sugars, proteins, etc. on the pet's body surface, achieving a cleaning effect. In addition, the small and uniform size of the microemulsion particles means that direct rinsing has a good cleaning effect, leaving no residue. This avoids repeated rubbing when using pet shampoo, reducing pet discomfort and hair loss. Detailed Implementation

[0081] II. Decontamination ability

[0082] Referring to GB / T13174-2021, the detergency of Examples 1-7 and Comparative Examples 1-5 on JB-02 protein-stained cloth and JB-03 sebum-stained cloth was determined by optical whiteness method. The soiled cloth was cut into 6×6cm square pieces, with at least 4 pieces in each group, for the determination of the detergency performance of one sample. The whiteness value of the soiled cloth before and after washing was measured using a whiteness meter at 457nm.

[0083] Before washing, the whiteness was measured by taking two points on each side of the test piece (the two points on the same side are centrally symmetrical). The average whiteness value of the four test pieces was taken as the whiteness of the test piece before washing, and denoted as F1.

[0084] Weigh 3g of sample, dissolve it in 250mg / kg hard water and bring the volume to 1000mL.

[0085] Preheat the vertical stain removal testing machine to 30±1℃. Add the prepared detergent to the washing test tank, add the soiled cloth (ensuring the cloth pieces do not overlap), start stirring at a speed of 5 r / min, and wash for 10 min. Remove the washed soiled cloth, rinse it thoroughly with deionized water, and place it on an enamel tray to air dry naturally. Take the washed and dried soiled cloth and measure its whiteness after washing according to the method for measuring whiteness before washing; record this as F2.

[0086] The stain removal value (R) of a soiled cloth can be expressed by the following formula:

[0087] R = ∑(F2-F1) / n; where F1 represents the spectral reflectance (%) of the test piece before washing; F2 represents the spectral reflectance (%) after washing; and n is the effective number of test pieces in each group.

[0088] P = R / R0, where R0 is the detergency of Libai dishwashing liquid (production license number YueXK16-114-00011) under the same conditions.

[0090]

[0091]

[0092] As shown in Tables 1 and 2, the anti-hair loss pet shampoo composition of the present invention can form a uniform microemulsion with an average particle size in the range of 20-35 nm. It has a high cleaning power even without stirring or rubbing, and can be better and more evenly distributed on the pet's body surface. Moreover, the microemulsion can dissolve oil, sugar, protein and other substances on the pet's body surface, thus achieving a cleaning effect. The microemulsion particles are small and uniform, and have a good cleaning effect with direct rinsing. There is no residue after rinsing, avoiding repeated rubbing when using pet shampoo. It has a high cleaning power even without rubbing, and reduces the pet's discomfort and hair loss by avoiding repeated rubbing.
