Description

Technical Field

[0001] The invention belongs to the technical field of pet cleaning products, and relates to a pet washing and care lotion, and in particular to a pet washing and care lotion and a preparation method thereof. Background Art

[0002] China's pet industry began to take shape in the 1990s. As the demand for pet food and supplies increased, international brands began to enter the Chinese market, which helped domestic pet owners develop a basic understanding of pet-related consumer products. During this period, pets changed from traditional "guardians" to "playmates / companions".

[0003] According to market research reports, the global pet economy industry scale will be approximately RMB 494.2 billion in 2021, and it is expected that the industry scale will exceed RMB 800 billion by 2025, an increase of more than 15% year-on-year. Among them, bath shampoo / hair conditioner and disinfection and deodorization products, as pet cleaning products, account for the highest proportion in the pet product consumption structure. As the number of pets and the size of the pet market increase, the market size of pet cleaning products will also grow accordingly.

[0004] Pets' skin is one of the biggest sources of odor. Uncleaned skin is prone to breeding bacteria, causing odor. In addition, a large amount of dirt and bacteria will adhere to the hair, which will combine with sebum secretions to produce a fishy smell. Currently, most pet care products focus on antibacterial, insect and mite removal, while deodorization and fragrance retention, another major function, has yet to be studied. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a pet washing and care lotion and a preparation method thereof, which has a reasonable formula, is simple to prepare, and has a long-lasting fragrance. It can effectively reduce the frequency of washing pets, allow pets to maintain a long-lasting fresh smell, and avoid damage to the pet's skin and hair due to frequent bathing.

[0038] The pearlescent agent used is the pearlescent paste produced by Guangzhou Chengnuo Biotechnology Co., Ltd., and its main components are ethylene glycol stearate, alkyl ether sulfate, and alkanolamide;

[0039] The oily fragrance used is produced by Guangzhou Baoshidi Flavor & Fragrance Co., Ltd., and the specific fragrance types of the oily fragrance are any one of orchid (model: 3768), aloe (model: 2757), and bergamot (model: 4211);

[0040] Example 1

[0041] This example provides a preparation method of a pet washing and care lotion, including the following steps:

[0042] Step 1: Weigh the raw materials by weight: 5 parts of sodium sulfosuccinate monoesters, 2 parts of coconut oil diethanolamide, 10 parts of cocamidopropyl hydroxysulfobetaine, 5 parts of sodium N-lauroylsarcosinate, 2 parts of trisodium ethylenediaminetetraacetate, 1 part of polyquaternium-22, 1 part of fragrance microcapsules, 2 parts of suspending agent carbomer sf-1, 3 parts of pearlescent agent, 0.05 part of citric acid, 0.5 part of sodium chloride, and 68 parts of deionized water;

[0043] Among them, the fragrance microcapsules are prepared by the following method:

[0044] S1: Weigh 5 parts of oily fragrance, 2 parts of dimethyl maleate, 0.01 part of azobisisobutyronitrile, 0.5 part of Tween-20, and 30 parts of deionized water by weight;

[0045] S2, adding Tween-20 to deionized water, heating to 40°C, and stirring thoroughly to completely dissolve the emulsifier to form an emulsifier solution; mixing the oily flavor, dimethyl maleate and azobisisobutyronitrile and stirring evenly to form an oil phase solution;

[0046] S3, slowly adding the emulsifier solution dropwise into the oil phase solution under stirring, and homogenizing at a speed of 11000 rpm for 5 min to form a stable emulsion;

[0047] S4, adding the emulsion prepared in step 3 into a pressure-resistant tube, filling it with nitrogen, and heating it to 60°C. After reacting for 8 hours, a fragrance microcapsule suspension is obtained, which is filtered, washed with a 30% ethanol solution, and dried to obtain a fragrance microcapsule powder;

[0048] Step 2: Add deionized water to a boiling pot, heat it to 80°C, add trisodium ethylenediaminetetraacetic acid and disodium sulfosuccinate in turn, keep warm and stir for 10 minutes to fully dissolve them, cool it down to 60°C, add coconut oil diethanolamide, cocamidopropyl hydroxysulfobetaine, sodium N-lauroyl sarcosinate, and polyquaternium-22, stir evenly, continue to cool down to 45°C, add carbomer sf-1, flavor microcapsules, and pearlescent agent in turn, stir for 10 minutes until uniform;

[0049] Step 3: Add citric acid to adjust the pH value to 6, add sodium chloride, and stir for 10 minutes until it is uniform to obtain a long-lasting fragrant pet shampoo and conditioner lotion.

[0050] Figure 1 This is the particle size distribution curve result of the flavor microcapsule in Example 1 of the present invention. After testing, the D90 of the flavor microcapsule is 2.112 μm, and its particle size distribution shows obvious normal distribution characteristics, indicating that the microcapsule has a relatively uniform particle size. This uniform particle size distribution helps to ensure the stable release of the flavor and the overall performance of the product.

[0051] Figure 2 is the scanning electron microscope characterization result of the flavor microcapsule in Example 1 of the present invention; Figure 2 It can be seen that the fragrance microcapsules are in a complete spherical shape, and the friction-broken capsules show that they have an obvious core-shell structure. This is crucial to ensure the effective encapsulation of the fragrance and the subsequent sustained release performance, thus laying the foundation for the long-lasting fragrance effect of the product.

[0052] Figure 3 is the thermogravimetric curve result of the flavor microcapsule in Example 1 of the present invention; Figure 3It can be seen that the weight loss rate of the first thermal weight loss is 70%, that is, the embedding rate of the essence microcapsule is 98%, which shows that it has excellent embedding effect. This feature ensures that the essence can be stably released for a long time, thus providing a strong guarantee for the long-lasting fragrance performance of the product.
