Description

Technical Field

[0001] This application relates to the field of daily chemical products technology, and more specifically, to an antibacterial and deodorizing fragrance composition, its preparation method, and its application. Background Technology

[0002] Fragrances are mixtures made by blending natural or synthetic flavorings to impart a specific aroma or fragrance characteristic to a product. Fragrances are classified in various ways, primarily according to their use, aroma characteristics, solubility, and dosage form: by use, they can be divided into daily-use fragrances (such as those used in soaps, creams, perfumes, etc.), food fragrances (suitable for beverages, candies, seasonings, etc.), and other-purpose fragrances; by aroma, they can be divided into floral, fruity, and aldehyde fragrances; by solubility, they can be divided into water-soluble (including alcohol-soluble) and oil-soluble types; and by dosage form, they include liquid (such as liquid, paste, emulsion) and solid (such as powder, block).

[0003] In daily-use fragrances, antibacterial and deodorizing fragrances combine active ingredients with bactericidal and bacteriostatic functions with fragrances. They effectively inhibit bacterial growth while providing a long-lasting fresh scent, making them widely used. The deodorizing function of antibacterial and deodorizing fragrances is mainly achieved through sensory modification and chemical deodorization. Sensory modification involves releasing chemicals with prominent odors to stimulate the olfactory and gustatory organs, diverting, distracting, or blurring attention from odors, reducing the nose's sensitivity to residual odors, and enhancing the feeling of freshness. Chemical deodorization involves reacting with odor molecules to transform them into odorless or low-odor substances. The antibacterial function of antibacterial and deodorizing fragrances is achieved through the effective inhibition of the growth of various bacteria and fungi by their volatile components.

[0004] Regarding the aforementioned technologies, the inventors believe that sensory modification relies on highly volatile fragrance raw materials, which can occupy olfactory receptors immediately; while chemical deodorization and antibacterial effects require active ingredients to remain on the action surface for a long time in order to continuously neutralize the constantly generated odor molecules or inhibit the growth of microorganisms. When sensory modification, chemical deodorization, and antibacterial ingredients are combined, it is often difficult to achieve a balance and coordination in their effects, resulting in the deodorization and antibacterial effects failing to meet expectations. Therefore, there is an urgent need to propose a solution to address the above-mentioned technical problems. Summary of the Invention

[0005] To achieve a better balance and coordination among the sensory modification, chemical deodorizing, and antibacterial components in fragrances, thereby exerting excellent deodorizing and antibacterial effects, this application provides an antibacterial and deodorizing fragrance composition, its preparation method, and its application. In a first aspect, this application provides an antibacterial and deodorizing fragrance composition, which adopts the following technical solution: An antibacterial and deodorizing fragrance composition, made from raw materials comprising the following parts by weight: 10-40 parts of chemically reactive deodorizing fragrance base; Sensory modification and receptor blocking: 30-60 parts of fragrance base; 5-20 parts of antibacterial and synergistic fragrance base; The chemically reactive deodorizing fragrance base is composed of component A and component B; Component A is one or more of citral, citronellol, and decanal; Component B is one or more of damascene ketone, durazone and methyl dihydrojasmonic acid. The sensory modification and receptor blocking fragrance base is composed of component C and component D; Component C is menthol and its derivatives; Component D is one or more of linalool acetate, dihydromyrceneol, and eucalyptol. The antibacterial and synergistic fragrance base is one or more of farnesol, eugenol, thymol, tea tree oil, and rosemary extract.

[0006] By employing the above technical solutions, for chemically reactive deodorizing fragrance bases, component A, an aldehyde fragrance containing an active carbonyl group (-CHO), reacts with the amino group (-NH2) in odor molecules to form a Schiff base reaction, generating odorless Schiff base compounds with larger molecular weights and water, thereby neutralizing the odor. Component B, an α,β-unsaturated carbonyl compound, undergoes a Michael addition reaction with sulfur-containing odor molecules such as thiols, covalently "locking" the sulfur group and causing it to lose its volatile odor. The synergistic effect between the two enhances the overall fragrance retention time and fixative effect, making the deodorizing effect more lasting and comprehensive. For sensory modification and receptor blocking fragrance bases, component C directly inhibits bitter taste receptors, blocking the perception of odor molecules and achieving deodorization at the receptor level. Component D interferes with or blocks the receptor's recognition of residual trace odor molecules, causing the brain to "ignore" these odor signals, enhancing subjective cleanliness and improving sensory experience. The synergistic effect of the two can exert excellent sensory modification and receptor blocking effects. For antibacterial and synergistic fragrance bases, it can effectively inhibit various odor-causing microorganisms such as Staphylococcus aureus and Moraxella osloi, reducing odor regeneration at the source and achieving a long-lasting effect. Through the combined use of the above-mentioned chemically reactive deodorizing fragrance bases, sensory modification and receptor blocking fragrance bases, and antibacterial and synergistic fragrance bases, the components promote each other and synergistically enhance each other's effects, organically combining sensory modification, chemical deodorization, and antibacterial functions while maintaining a good balance and coordination, thereby exerting excellent deodorizing and antibacterial effects.

[0007] Preferably, the weight ratio of the chemically reactive deodorizing fragrance base, the sensory modification and receptor blocking fragrance base, and the antibacterial synergistic fragrance base is 6:11:3.

[0008] By adopting the above technical solutions, the sensory modification and receptor blocking fragrance bases in the above proportions can quickly release fragrance, mask odors immediately, and rapidly occupy olfactory receptors, ensuring the immediacy and durability of sensory modification and receptor blocking; the chemically reactive deodorizing fragrance bases in the above proportions ensure sufficient concentration of active ingredients while avoiding irritation that may result from excessive use, and can maintain deodorizing ability for a longer period of time; the antibacterial synergistic fragrance bases in the above proportions can achieve the best balance of antibacterial effects; therefore, at the above proportions, through scientific volatility gradients, synergistic effects of functional ingredients, and safety considerations, a perfect balance of the three major functions of sensory modification, chemical deodorization, and antibacterial properties can be achieved, ultimately resulting in an antibacterial and deodorizing fragrance composition with superior application quality.

[0009] Preferably, the chemically reactive deodorizing fragrance base is composed of component A and component B in a weight ratio of 1:(0.8-1.2).

[0010] By adopting the above technical solution, component A has relatively high volatility, which can quickly release fragrance, mask odors immediately, and provide an immediate deodorizing effect; component B has low volatility, which can prolong the overall fragrance retention time and ensure the longevity of the deodorizing effect; under the above ratio, the chemical synergy, volatility gradient balance, sensory modification and chemical deodorization coordination are better, and finally a high-quality antibacterial and deodorizing fragrance composition can be obtained.

[0011] Preferably, component A is composed of the following components in parts by weight: Citral 7.5-8.5 parts; Citronellol 6.5-7.5 parts; Component B is methyl dihydrojasmonic acid.

[0012] By adopting the above technical solution, citral and citronellol have active aldehyde structures and relatively high volatility, which can quickly release fragrance, mask odors immediately, and provide an immediate deodorizing effect; methyl dihydrojasmonate has an elegant and soft jasmine fragrance, long-lasting scent, and low volatility, which can extend the overall fragrance time and ensure the longevity of the deodorizing effect; when the above raw materials are used as component A and component B respectively, a perfect combination of immediate deodorization and long-lasting fragrance is achieved, thereby enabling the chemically reactive deodorizing fragrance base to exert its excellent corresponding effect.

[0013] Preferably, the sensory modification and receptor blocking fragrance is composed of component C and component D in a weight ratio of 1:(1.5-2).

[0014] By adopting the above technical solution, component C can directly interact with the odor binding site, physically inhibiting the binding of natural odor molecules, thereby preventing receptor activation and achieving sensory-level deodorization; component D, as a mid-note component, can prolong the overall fragrance retention time and ensure the longevity of the deodorization effect; the combination of the two in the above ratio can balance the volatility gradient and optimize the fragrance retention performance, achieving immediate sensory modification and receptor blocking, as well as long-lasting effects, ultimately obtaining an antibacterial and deodorizing fragrance composition with better application quality.

[0015] Preferably, component C is menthol; Component D consists of the following components in parts by weight: 15-25 parts of linalyl acetate; 10-20 parts of dihydromyrcenol.

[0016] By adopting the above technical solution, menthol has high volatility and can release aroma quickly, occupy olfactory receptors immediately, and provide immediate sensory modification effect; linalyl acetate and dihydromyrcenol can continuously release aroma, form a good aroma transition with menthol, and can synergistically exert excellent sensory modification and receptor blocking effects with menthol, thereby enabling the sensory modification and receptor blocking fragrance groups to exert excellent corresponding effects.

[0017] Preferably, the antibacterial and synergistic flavor base is composed of the following components in parts by weight: Farnesol 4-6 parts; 4-6 parts thymol; Tea tree oil, 4-6 parts.

[0018] By adopting the above technical solution, farnesol is a sesquiterpene alcohol with multiple antibacterial mechanisms, thymol can inhibit the formation of biofilms without affecting bacterial growth, and terpinene-4-ol, the main active ingredient of tea tree oil, has broad-spectrum antibacterial activity. The combination of the three components at the above dosage can achieve a highly efficient, safe, and long-lasting antibacterial effect through synergistic action of multiple mechanisms, broad-spectrum antibacterial coverage, and a balance of safety, ultimately obtaining an antibacterial and deodorizing fragrance composition with better application quality.

[0019] Secondly, this application provides a method for preparing an antibacterial and deodorizing fragrance composition, using the following technical solution: A method for preparing an antibacterial and deodorizing fragrance composition includes the following steps: (1) Prepare raw materials containing chemically reactive deodorizing fragrance base, sensory modification and receptor blocking fragrance base, and antibacterial and synergistic fragrance base according to the formula ratio; (2) The chemically reactive deodorizing fragrance base, sensory modification and receptor blocking fragrance base, and antibacterial and synergistic fragrance base raw materials from step (1) are placed in a stirring container and stirred and mixed. After the mixture is evenly mixed, the resulting liquid mixture is homogenized under high pressure to obtain an antibacterial and deodorizing fragrance composition.

[0020] By adopting the above technical solution, the above preparation method is relatively simple and suitable for large-scale industrial production. Furthermore, high-pressure homogenization after uniform mixing of the raw materials is beneficial to ensure that the raw materials are fully mixed, thereby ensuring that a high-quality and stable antibacterial and deodorizing fragrance composition is obtained.

[0021] Thirdly, this application provides an application of an antibacterial and deodorizing fragrance composition in daily chemical products, employing the following technical solution: The application of an antibacterial and deodorizing fragrance composition in daily chemical products, including fabric washing and care products, space fragrance products, and personal care products.

[0022] By adopting the above technical solutions, the antibacterial and deodorizing fragrance composition can effectively solve the problems of odor and bacteria in three dimensions: fabrics, space and human body, and achieve all-round deodorization and antibacterial protection from the source to the end.

[0023] In summary, this application has the following beneficial effects: This application utilizes a combination of chemically reactive deodorizing fragrance bases, sensory-modifying and receptor-blocking fragrance bases, and antibacterial synergistic fragrance bases, based on specific raw material combinations. This allows the components to promote each other and synergistically enhance each other's effects, organically combining sensory modification, chemical deodorization, and antibacterial functions while maintaining optimal balance and coordination. This results in excellent deodorizing and antibacterial effects, ultimately yielding an antibacterial and deodorizing fragrance composition with superior application quality. Detailed Implementation

[0042] Test method: Under constant temperature (23±1°C) and constant humidity (50±5%RH) for 1m 3 The sealed olfactory chamber is filled with ammonia gas (50 ppm) and hydrogen sulfide gas (20 ppm) at standard concentrations. Place a glass slide coated with a bacterial solution of 1.0 × 10⁻⁶. 6 CFU / mL, coating amount 0.01mL / cm 2 Then, a pet deodorizing fragrance composition was sprayed onto the glass slide carrier at a concentration of 0.5 mg / cm². 2The bacterial strains used were Staphylococcus aureus (ATCC 6538), Escherichia coli (8099), and Candida albicans (ATCC 10231), and three slides were used. Ten professional evaluators with normal sense of smell (no rhinitis, colds, or other illnesses) were selected and required to pass the ISO 8586 standard olfactory sensitivity test. Then, an antibacterial and deodorizing fragrance composition was sprayed into the olfactory chamber at a rate of 0.6 mL / m². 3 One minute after spraying, a professional evaluator enters and completes the scoring within one minute. The scoring is based on a 10-point scale (1 = obvious odor and large odor residue, 10 = completely masked and no odor residue). The average score given by the professional evaluator is recorded as the final score.

[0043] Meanwhile, the inhibition rate was measured after 1 hour. The inhibition rate (%) = (initial bacterial count - bacterial count after 1 hour) / initial bacterial count × 100%. The average value of the three types of bacteria was recorded as the average inhibition rate.
