Description

Technical Field

[0001] The invention belongs to the technical field of daily chemicals, and in particular relates to a fragrant and antibacterial shower gel composition and a preparation method thereof. Background Art

[0002] As a daily cleaning and care product, shower gel plays an important role in people's lives. With the improvement of living standards, consumers are not only concerned about the cleaning ability of shower gel, but also have higher requirements for its antibacterial efficacy and user experience. Traditional shower gels often use chemical antibacterial agents such as triclosan and methylisothiazolinone to inhibit bacterial growth. However, these chemical antibacterial agents have potential irritation and safety risks. Long-term use may cause skin allergies and disrupt the balance of the skin's microbiome. At the same time, existing light-fragrance shower gels often rely on synthetic fragrances to create fragrance. The fragrance is single and has poor long-lasting properties, which makes it difficult to meet consumers' demand for natural, fresh and long-lasting fragrance.

[0003] Therefore, developing a shower gel composition with high-efficiency antibacterial performance and natural fragrance and a preparation method thereof are of great significance to improving the quality and market competitiveness of shower gel products. Summary of the Invention

[0004] The object of the present invention is to provide a fragrant and antibacterial shower gel composition and a preparation method thereof, which solves the problem that the existing compositions added to shower gels have poor antibacterial and fragrance properties.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A fragrant and antibacterial shower gel composition, comprising the following raw materials in parts by weight:

[0007] 0.2-0.4 parts by weight of plant fermentation filtrate, 3-5 parts by weight of cedarwood oil, 0.5-0.9 parts by weight of yarrow oil, 2-3 parts by weight of vetiver root oil, 1-1.2 parts by weight of vanillin, and 85-90 parts by weight of solvent.

[0008] Yarrow (ACHILLEA MILLEFOLIUM) oil has a light, refreshing fragrance that cleanses and balances oil levels on the skin. Cedar (CEDRUSDEODARA) wood oil has a sweet, woody fragrance that moisturizes and nourishes the skin. Vetiver (VETIVERIA ZIZANIOIDES) root oil has a rich, woody, and earthy aroma. It is a relatively viscous essential oil that forms a protective layer on the skin, reducing moisture and aroma loss. Vanillin can combine with other aroma molecules through hydrogen bonds, reducing the volatility of the overall aroma mixture.

[0009] As a preferred technical solution of the present invention, the plant fermentation filtrate includes the following raw materials:

[0010] Oroxylum butterfly root, sea buckthorn fruit, pear fruit, compound bacterial activation solution and deionized water;

[0011] Oroxylum indicum is a plant of the Bignoniaceae family. The roots of Oroxylum indicum mainly contain active ingredients of flavonoids and their glycosides, which can inhibit the activity of key enzymes in bacteria and thus interfere with the metabolic process of bacteria. It has excellent in vitro antibacterial activity.

[0012] Sea buckthorn (HIPPOPHAE RHAMNOIDES) is a deciduous shrub of the genus Hippophae in the family Elaeagnaceae. Sea buckthorn fruit is rich in flavonoids and polyphenols, which can remove free radicals produced during bacterial metabolism and inhibit bacterial growth and reproduction.

[0013] Pyrus communis is a fruit tree of the genus Pyrus in the Rosaceae family. Pear fruit contains flavonoids and phenolic acids, which can destroy the integrity of cell membranes and cause leakage of intracellular substances.

[0014] As a preferred technical solution of the present invention, the amount of the Oroxylum indicum root is 2-4 parts by weight, the amount of the sea buckthorn fruit is 42-47 parts by weight, and the amount of the Pyrus communis fruit is 15-18 parts by weight.

[0015] As a preferred technical solution of the present invention, the addition amount of the composite bacterial strain activation liquid is 0.4-0.6% of the total mass of the oroxylum indicum root, sea buckthorn fruit and western pear fruit; the addition amount of the deionized water is 4-5 times the total mass of the oroxylum indicum root, sea buckthorn fruit and western pear fruit.

[0016] Furthermore, the composite bacterial strain activation liquid comprises Lactobacillus plantarum activation liquid, Bacillus subtilis activation liquid and Lactobacillus bulgaricus activation liquid, which are mixed in a mass ratio of 3-3.5:1-1.4:1.8-2.2.

[0017] Furthermore, the Lactobacillus plantarum activated solution and the Lactobacillus bulgaricus activated solution are activated solutions obtained by inoculating Lactobacillus plantarum and Lactobacillus bulgaricus into MRS culture medium and culturing them according to a conventional method, and the Bacillus subtilis activated solution is activated solution obtained by inoculating Bacillus subtilis into LB culture medium and culturing them according to a conventional method. The above-mentioned culture medium and culture method have no special requirements that are different from those known in the art. The key is to ensure that the effective viable bacteria count of the Lactobacillus plantarum activated solution reaches 1.8-2×10 7 The effective number of viable bacteria in the activated Bacillus subtilis solution is 1-1.5x10 7 The CFU / mL range of Lactobacillus bulgaricus activated solution is 1.5-1.8x107 CFU / mL range, then the purpose of the present invention can be achieved.

[0018] As a preferred technical solution of the present invention, the method for preparing the plant fermentation filtrate comprises the following steps:

[0019] Chop the oroxylum butterfly roots, sea buckthorn fruits and pear fruits, mash them, add deionized water and stir evenly, control the temperature and sterilize to obtain a mixed solution A, control the temperature and add the composite bacterial strain activation liquid to the mixed solution A, mix evenly, control the temperature and ferment, control the temperature and inactivate after the fermentation is completed, filter and centrifuge to obtain the plant fermentation filtrate.

[0020] Furthermore, the temperature of the temperature-controlled sterilization is 121°C, and the time is 30-35 minutes; the temperature of adding the composite bacterial strain activation liquid to the mixed liquid A is 35-38°C; the temperature of the temperature-controlled fermentation is 35-38°C, and the time is 72 hours; the temperature of the temperature-controlled inactivation is 121°C, and the time is 25-30 minutes.

[0021] As a preferred technical solution of the present invention, the solvent comprises deionized water and anhydrous ethanol in a mass ratio of 2:1-1.5.

[0022] A method for preparing a fragrant and antibacterial shower gel composition comprises the following steps:

[0023] S1. Evenly mix cedarwood oil, yarrow oil, vetiver root oil, and anhydrous ethanol under temperature control to obtain a mixed solution A, which is set aside; evenly mix the remaining raw materials to obtain a mixed solution B, which is set aside;

[0024] S2. Mixed liquid A and mixed material B are stirred at controlled temperature and then homogenized to obtain a finished composite product.

[0025] As a preferred technical solution of the present invention, the temperature of the temperature control in step S1 is 28-30°C.

[0026] As a preferred technical solution of the present invention, the temperature of the temperature control in step S2 is 30-32° C., the stirring time is 30-45 minutes, and the homogenization time is 3-5 minutes.

[0027] The invention discloses an application of a fragrant and antibacterial shower gel composition in preparing shower gel. The application comprises adding the shower gel composition into the shower gel.

[0028] As a preferred technical solution of the present invention, the addition amount of the shower gel composition is 2-3% of the total mass of the shower gel.

[0029] Beneficial effects of the present invention:

[0030] (1) The present invention selects pear fruit, oroxylum root and sea buckthorn fruit as the main antibacterial ingredients. The raw materials complement each other and can synergistically exert a certain antibacterial effect from the direction of destroying the integrity of cell membranes, interfering with bacterial metabolic processes and inhibiting bacterial growth and reproduction. On this basis, the composite bacterial strain activation liquid is added to further activate the active ingredients in the plant raw materials, which can effectively enhance the antibacterial efficiency and antibacterial effect of the finished product.

[0031] (2) The yarrow oil selected in the present invention can balance oil, cedarwood oil can moisturize and nourish, and vetiver root oil can form a protective layer on the skin surface. The combination of the three can make the finished product have outstanding moisturizing and hydrating effects, and can soften the skin. In addition, the combined use of yarrow oil, cedarwood oil and vetiver root oil can also give the user a cool, refreshing and natural smell of being in the deep mountains and dense forests. On this basis, vanillin is added, which combines with the aroma molecules in the system through its hydrogen bonds, effectively reducing the volatilization rate of the overall aroma of the system, making the fragrance last for a long time. In this way, the finished product of the composition has both a refreshing fragrance and a moisturizing effect, which can greatly improve the overall quality of the product. DETAILED DESCRIPTION
