Description

Technical Field

[0001] The invention relates to the field of pet lotions, and in particular to a pet essential oil lotion and a preparation method thereof. Background Art

[0002] With the rapid development of the pet market, the cleaning problem of pets has gradually received attention. Pet wash is a cleaning and care product specially designed for pets, which has the functions of cleaning, deodorizing, protecting hair, removing mites, and antibacterial. In order to reduce irritation to pet skin, pet wash containing natural ingredients and pure plant formulas has gradually been favored by consumers. Pet essential oil wash is a pet care product that combines the properties of essential oils and washes. Essential oils are natural aromatic compounds extracted from plants and have various potential health benefits. Pet essential oil washes usually contain some essential oils that are beneficial to pets, such as lavender, mint, Roman chamomile, frankincense and cedar. These essential oils are believed to provide effects such as reducing anxiety, repelling insects, skin care and promoting hair health.

[0003] Patent CN110051598A discloses a pet skin care cleaning liquid and a preparation method thereof, wherein the pet skin care cleaning liquid comprises the following raw materials: long carbon chain fatty acids, sandalwood essential oil, polysorbate alkali metal soap, collagen, dioctyl sodium sulfosuccinate, liquid complex enzyme, sweet potato vine, longitudinal muscle anemone, wild nightshade, flower stalk, rosary root scutellaria, purple bamboo root and ganoderma lucidum. The prepared pet skin care cleaning liquid has a cleaning effect and can regulate the microecological balance to improve immunity, improve the health level of pet dogs, and improve the digestibility of microbial feed preparations. At the same time, it can avoid the side effects such as pollution and drug resistance caused by the use of antibiotics. However, the polysorbate alkali metal soap used in it is easy to irritate the skin and induce allergies.

[0004] Patent CN105560096B discloses a pet antipruritic cleaning liquid and a preparation method thereof, wherein the pet antipruritic cleaning liquid is made of the following materials: polyoxyethylene ether, alkylphenol polyoxyethylene ether, polyether quaternized polysiloxane, thyme essential oil, hydroxyethyl cellulose, camptotheca bark, fine-leaved seven-star sword, Tibetan sorrel, lavender, Schefflera chinensis, salt bran root, hornwort, yangsuizu, wild ramie, Yichang viburnum, feather calyx, swertia asarum, straight-stemmed eucalyptus leaves, bamboo leaf pepper, corydalis, catalpa leaves and oxalis, and the pet antipruritic cleaning liquid has a good cleaning effect, and the addition of traditional Chinese medicine ingredients can effectively relieve itching and inflammation, and eradicate inflammation of pet skin. However, the pet antipruritic cleaning liquid does not contain antibacterial ingredients, and the antibacterial effect is poor.

[0005] Therefore, there is an urgent need for a pet essential oil lotion with good antibacterial effect and not prone to skin irritation on the market. Summary of the invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to obtain a pet essential oil lotion which has good antibacterial and mite removal effects, good antipruritic and hair protection effects, easy penetration of effective ingredients and is not easy to irritate the skin.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] The first aspect of the present invention provides a pet essential oil lotion, which comprises the following raw materials in parts by weight: 25-30 parts of frankincense essential oil, 15-25 parts of anti-mite essential oil, 10-15 parts of modified castor oil, 10-15 parts of antimicrobial peptides, 5-7 parts of penetration enhancers, 1-3 parts of menthol, 1-2 parts of methylparaben, and 1-2 parts of ethylparaben.

[0009] The present application provides a kind of pet essential oil lotion, comprising frankincense essential oil, repellent mite essential oil, modified castor oil, antimicrobial peptide, the essential oil lotion not only has antibacterial and insecticidal effects, but also can provide a cool feeling, and help relieve the itching discomfort of pets. Frankincense essential oil can promote wound healing, enhance immunity, and frankincense essential oil can also strengthen mental strength, relieve anxiety and depression. Menthol has the effects of antipruritic, astringent, anti-inflammatory, wound protection, wound healing, and penetration promotion, and methylparaben and ethylparaben can play the functions of antioxidant, softener, emulsifier, stabilizer, and bactericidal preservative. In addition, the present invention also includes a penetration enhancer, which can ensure that the essential oil components can be evenly distributed on the surface of pet skin, and continuously release over a long period of time to enhance the therapeutic effect, and can make methylparaben and ethylparaben easily enter the skin surface to achieve the effect of deep sterilization. The essential oil lotion of the present invention has the characteristics of easy use, fast action and high safety, and can be directly used for skin cleaning of pets or used in conjunction with pet shampoo to enhance cleaning and therapeutic effects.

[0010] In some embodiments, the method for preparing the modified castor oil comprises the following steps:

[0011] A1. Add castor oil and sodium sulfate to glycerol, and react at 65-85°C for 7-9h to obtain glycerol-modified castor oil;

[0012] A2. Add the hydrolyzed protein, the glycerol-modified castor oil obtained in step A1 and sulfuric acid into a reaction vessel, heat to 75-85° C. and react for 3-4 hours, and obtain modified castor oil after drying.

[0013] Castor oil has lubricating, moisturizing, antistatic, and antibacterial effects. It can be mixed with essential oils and used as a base oil. It can also be coated on the surface of the essential oil during the use of the essential oil so that the essential oil can be evenly distributed on the pet's skin surface and continuously released for a long time. However, castor oil is highly hydrophobic and has a large molecular weight, which can easily clog pores and make the antibacterial components difficult to be absorbed. The present application first uses glycerol to modify castor oil to obtain a glycerol-modified castor oil with a low molecular weight and a high hydroxyl content, and reacts it with hydrolyzed protein. On the one hand, the pet essential oil lotion can be made to soften the hair and relieve skin itching. On the other hand, the hydrolyzed protein has a similar molecular structure to the keratin in the hair, so that the castor oil is easily absorbed by the hair and is not easy to clog the pores.

[0014] In some embodiments, the mass ratio of castor oil to glycerol is 1:(3-5).

[0015] In some embodiments, the mass ratio of the hydrolyzed protein to the glycerol-modified castor oil in step A2 is (0.4-0.6):1.

[0016] Glycerol-modified castor oil may have poor affinity with essential oils. The present application limits the mass ratio of castor oil to glycerol and the mass ratio of hydrolyzed protein to glycerol-modified castor oil, so that castor oil has better affinity with essential oils while increasing the hydroxyl content, making it less likely to clog pores, which is beneficial to improving the antibacterial effect and hair protection effect of the essential oil lotion.

[0017] In some embodiments, the mite repellent essential oil is one or more of lavender essential oil, tea tree essential oil, rosemary essential oil, eucalyptus essential oil, and lemon essential oil.

[0018] Preferably, the anti-mite essential oil is a composition of lavender essential oil and tea tree essential oil, and the mass ratio of the two is 1:(1-2).

[0019] Lavender essential oil has antibacterial and anti-inflammatory effects, soothing and relaxing, repairing sensitive skin and protecting hair; tea tree essential oil has antimicrobial and anti-inflammatory properties and is also widely used in skin care, which can help open the skin's permeability channels. The synergistic effect of the two essential oils can make the essential oil lotion have a better bactericidal and mite-removing effect.

[0020] In some embodiments, the antimicrobial peptide is a Bacillus fermentation product.

[0021] In some embodiments, the preparation method of the penetration enhancer comprises the following steps:

[0022] B1, adding lecithin, hydrogen peroxide and acetic acid to ethanol, reacting at 55-70°C for 2-3h, washing and drying to obtain hydroxylated lecithin;

[0023] B2. Add the hydroxylated lecithin and gallic acid obtained in step B1 into a reaction vessel, and react at 70-80° C. for 3-4 hours to obtain the product.

[0024] Lecithin has a structure similar to that of the skin and has a penetration-promoting effect. The present application uses gallic acid to modify hydroxylated lecithin, so that the hydroxylated lecithin contains a phenol structure, so that the essential oil lotion has a better antioxidant effect and can prevent the effective components from being oxidized. The benzene ring can generate π-π intermolecular forces with the benzene rings on methylparaben and ethylparaben, which can promote its absorption by the skin.

[0025] In some embodiments, the lecithin is egg yolk lecithin.

[0026] The present application uses egg yolk lecithin to prepare a penetration enhancer, which can have a good hair protection effect while exerting a penetration enhancing effect.

[0027] In some embodiments, the mass ratio of lecithin to hydrogen peroxide is 1:(0.2-0.4).

[0028] In some embodiments, the mass ratio of hydroxylated lecithin to gallic acid in step B2 is 1:(0.1-0.3).

[0029] The introduction of gallic acid segments may cause the penetration enhancer to irritate the skin. The present application limits the mass ratios of lecithin and hydrogen peroxide and hydroxylated lecithin and gallic acid to improve the antioxidant and penetration-enhancing properties of pet essential oil lotions while reducing irritation to pet skin.

[0030] A second aspect of the present invention provides a method for preparing a pet essential oil lotion, comprising the following steps:

[0031] S1, adding frankincense essential oil and mite repellent essential oil to modified castor oil, stirring at 70-80° C. for 20-30 min, cooling to room temperature, and obtaining an oily substance;

[0032] S2, adding antimicrobial peptide, penetration enhancer, menthol, methylparaben and ethylparaben into a container, stirring at 25-35° C. for 40-60 min to obtain a mixture;

[0033] S3. Add the mixture obtained in step S2 to the oil obtained in step S1, and stir at 25-35° C. for 1-2 h to obtain the product.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] (1) The present invention provides a pet essential oil lotion, comprising frankincense essential oil, mite-repellent essential oil, modified castor oil, and antimicrobial peptides. The synergistic effect of the substances enables the pet essential oil lotion to have the advantages of good antibacterial and mite-removing effects, good antipruritic and hair-protecting effects, easy penetration of effective ingredients, and not easy to irritate the skin. In addition, the present invention also includes a penetration enhancer, which can ensure that the essential oil components can be evenly distributed on the pet's skin surface and continuously released for a long time to enhance the therapeutic effect, and can also make methylparaben and ethylparaben easily enter the skin surface to achieve a deep sterilization effect.

[0036] (2) The present invention first uses glycerol to modify castor oil to obtain a glycerol-modified castor oil with a low molecular weight and a high hydroxyl content, and then reacts the glycerol-modified castor oil with hydrolyzed protein to obtain modified castor oil. On the one hand, the pet essential oil lotion can have the effects of softening hair and relieving skin itching. On the other hand, the hydrolyzed protein has a similar molecular structure to the keratin in the hair, so that the castor oil is easily absorbed by the hair and is not easy to clog the pores.

[0037] (3) The present invention uses gallic acid to modify hydroxylated lecithin, so that the hydroxylated lecithin contains a phenol structure, so that the essential oil lotion has a better antioxidant effect and can prevent the effective components from being oxidized. The benzene ring can generate π-π intermolecular forces with the benzene rings on methylparaben and ethylparaben, which can promote its absorption by the skin. DETAILED DESCRIPTION

[0085] Performance Testing

[0086] The clinical efficacy of the pet essential oil lotions obtained in the above embodiments and comparative examples for treating canine fungal skin diseases was tested:

[0087] 1. General Information

[0088] 240 sick dogs clinically diagnosed with fungal skin diseases, including various pet dogs (including Border Collies, Teddy, Bulldogs, etc.) (aged 1 to 5 years old), were shaved as experimental animals. The sick dogs were divided into 8 groups, 30 in each group. The sick dogs showed severe itching, large areas of hair loss on the chest, back, and limbs, scattered erythema and papules on the body surface, flushing and congestion of the skin, and thick oily scabs on the hair loss area and surrounding hair roots. As the course of the disease prolonged, melanin deposition occurred in the affected area. Microscopic examination of the affected area dandruff and hair roots showed a large number of bamboo-leaf-shaped fungal spores, and the hair roots were surrounded by a large number of fungal spores in a tube-like shape. Dogs infected with Trichophyton had a thumb-sized hair loss area on their bodies, which resembled the markings on the body surface of a sika deer. Parasitic mites can be detected in case of mixed infection with mites.

[0089] 2. Treatment methods

[0090] Use pet essential oil wash at a dosage of 1.5ml / kg body weight to bathe the sick dog once every two days.

[0091] 3. Clinical efficacy evaluation

[0092] Seven days after administration, dandruff or hair from eight different infected parts of each animal was collected for isolation and identification of pathogenic bacteria. According to the Compilation of Guidelines for Veterinary Drug Research, the results of clinical efficacy tests were divided into three levels: "cured, effective, and ineffective."

[0093] Cure: The rate of negative conversion of skin pathogen isolation is ≥80%, and at the same time, the inflammatory secretions disappear, and the symptoms of rash, dandruff, pus and itching disappear.

[0094] Effective: 60% ≤ Negative conversion rate of skin pathogen isolation < 80%, at the same time, inflammatory secretions are reduced, rashes, dandruff, pus, etc. are reduced, and itching symptoms are alleviated.

[0095] Ineffective: The rate of negative conversion of skin pathogen isolation is <60%, while inflammatory secretions still exist, and there is no reduction in rashes, dandruff, and pus.

[0096] Total effective rate = ((number of cured cases + number of effective cases) ÷ 30) × 100%.

[0097] 4. Hair protection effect

[0098] The hair care effect of pet essential oil lotion was evaluated by the coat color status of pet dogs.

[0099] The test results are shown in Table 1:

[0100] Table 1

[0101] Group Number of cures Valid Number Invalid number Total Effectiveness Coat color status Example 1 24 4 2 93.3％ Shiny and smooth Example 2 23 4 3 90.0％ Shiny and smooth Example 3 25 3 2 93.3％ Shiny and smooth Example 4 22 4 4 86.7％ Shiny and smooth Example 5 21 5 4 86.7％ Dull, rough Example 6 20 5 5 83.3％ Dull, rough Example 7 18 5 7 77.7％ Shiny and smooth Comparative Example 1 16 4 10 66.7％ Dull, rough

[0102] It can be seen from the data in Table 1 that the pet essential oil lotions in Examples 1-3 of the present invention have the advantages of good antibacterial effect and good hair protection effect. From the comparison between Examples 4 and 5 and Example 1, it can be seen that changing the ratio of castor oil and glycerol or hydrolyzed protein and glycerol-modified castor oil will cause the affinity of glycerol-modified castor oil to the essential oil to deteriorate, resulting in the deterioration of the bactericidal effect and hair protection effect of the pet essential oil lotion; from the comparison between Example 6 and Example 1, it can be seen that changing the ratio of hydroxylated lecithin and gallic acid will cause the penetration enhancer to irritate the skin, resulting in the deterioration of the bactericidal effect and hair protection effect of the pet essential oil lotion; from the comparison between Example 7 and Example 1, it can be seen that the bactericidal effect of the pet essential oil lotion is deteriorated by directly adding egg yolk lecithin; from the comparison between Comparative Example 1 and Example 1, it can be seen that without modifying castor oil, the bactericidal effect and hair protection effect of the pet essential oil lotion are deteriorated.

[0103] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
