Description

Technical Field

[0001] The present application relates to the technical field of daily chemical fragrances, and more specifically, to a mild and hypoallergenic fragrance for children's care products and a preparation method thereof. Background Art

[0002] In the field of childcare products, as parents' concern for their children's health continues to grow, their requirements for product safety and mildness are becoming increasingly stringent. Fragrances are commonly added to childcare products to improve the product's scent and enhance the user experience.

[0003] Traditional daily fragrances are often made from synthetic chemicals with complex ingredients. Some of these chemicals may irritate children's delicate skin and sensitive respiratory tract, triggering allergic reactions such as redness, itching, and respiratory discomfort. In recent years, cases of allergies in children from using skincare products containing irritating fragrances have been on the rise. Camellia, with its soothing and nourishing properties, has gradually gained attention in the skincare market. The development of a children's care fragrance using natural camellia extract as its core ingredient eliminates the irritants that may be present in traditional synthetic ingredients, ensuring the fragrance is highly safe and gentle on children's delicate skin and sensitive respiratory tract, reducing the risk of allergies at the source. Its elegant and pleasant aroma is also well-received by the public.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the essence is composed of substances containing volatile components and sensitive activities, and it is difficult to maintain stable fragrance release during the release process. Although the above-mentioned camellia floral fragrance has a unique fragrance that is mild and low-sensitivity, it sacrifices the persistence and stability of the fragrance, and it is difficult to meet the comprehensive needs of parents for high quality, safety and good user experience of children's care products.

[0005] Therefore, it is urgent to propose a solution to solve the above technical problems. Summary of the Invention

[0006] In order to solve the problems of short lasting fragrance and poor stability of existing hypoallergenic fragrances, and to enable camellia floral fragrance to stably release fragrance and prolong lasting fragrance when used in children's care products, the present application provides a mild hypoallergenic fragrance for children's care products and a preparation method thereof.

[0007] In a first aspect, the present application provides a mild hypoallergenic fragrance for child care products, which adopts the following technical solution: A mild hypoallergenic fragrance for child care products, comprising the following raw materials in parts by weight: 5-10 parts of methyl dihydrojasmonate; 10-50 parts of fragrance solvent; 10-50 parts of ambergris; Musk T1-5 parts; 1-5 parts of lily of the valley pyran; 1-5 parts of Galaxanthide stock solution; 1-5 parts of ethyl linalool.

[0008] By adopting the above technical solution, methyl dihydrojasmonate has a rich sweet floral fragrance with a slight hint of fruit and jasmine, as well as a fresh and soft lemon-like fruity aroma, and can be used as a main fragrance or a coordinating agent; ambergris acts as a fixative in fragrances and can give fragrances a vivid, lasting and harmonious aroma; musk T can effectively fix the aroma of other fragrances, making them more lasting and harmonious, and has excellent diffusivity, allowing the fragrance of the fragrance to be more evenly diffused into the air, enhancing the overall fragrance effect; lily of the valley pyran has a fresh, soft, and natural lily of the valley fragrance with a frankincense note and can enhance the floral aroma; galaxolide stock solution has a strong and lasting musk aroma accompanied by woody notes, with a sweet, green and powerful aroma, excellent penetration and diffusivity, and long-lasting fragrance, and is often used in the preparation of spices and fragrances; ethyl linalool can significantly increase the richness and persistence of fragrance. The combination of the above raw materials can accurately formulate the camellia floral fragrance, completely preserving the fresh and elegant characteristics of the camellia fragrance; at the same time, the compounding of methyl dihydrojasmonate, ambergris and musk T can not only synergistically enhance the fragrance persistence, but also delay the release through the macromolecular structure and form a double-layer fragrance fixative system, exerting an excellent compound synergistic effect, which can solve the problems of short fragrance lasting time and poor stability of existing low-sensitivity fragrances, so that the camellia floral fragrance can stably release fragrance and prolong the fragrance lasting time when used in children's care products.

[0009] Preferably, the raw materials are further added with 1-5 parts by weight of a functional additive, which consists of composition A, composition B and glycerol; The composition A consists of tea polyphenols and aloe vera gel; The composition B consists of lotus leaf wax and palm wax.

[0010] By adopting the above technical scheme, in composition A, tea polyphenols contain highly active phenolic hydroxyl groups, which can inhibit the oxidative decomposition of flavor ingredients, and can form an antioxidant network in combination with aloe vera gel to improve the stability of the flavor ingredients; in composition B, lotus leaf wax can avoid the sudden release of fragrance to a certain extent, and palm wax can form a rigid skeleton, and by maintaining structural stability, ensure that the release rate is linearly controllable. The combination of the two can significantly improve the fragrance retention time and stability of low-sensitivity flavors; glycerin can improve the coordination between composition A and composition B, and coordinate it to deeply act on other component raw materials to achieve a balance between interactions, and then after the application of functional additives, it can significantly improve the application stability of mild low-sensitivity flavors for children's care products, bringing about an excellent improvement in stable fragrance release and extended fragrance retention time.

[0011] Preferably, the composition A is composed of tea polyphenols and aloe vera gel in a weight ratio of 1:(1.8-2.6).

[0012] By adopting the above technical solution, excessive tea polyphenols are prone to precipitation, and excessive aloe vera gel will hinder the release of flavors. When tea polyphenols and aloe vera gel are used in combination in the above weight ratio, the two have a better synergistic effect and have uniform dispersion in the mixed system of mild and low-sensitivity flavors for children's care products, so that the functional additives can exert better application effects.

[0013] Preferably, the composition B is composed of lotus leaf wax and palm wax in a weight ratio of (0.3-0.5):1.

[0014] By adopting the above technical solution, an excessive amount of lotus leaf wax is insufficient to form continuous contact with the rigid skeleton dominated by palm wax, and an excessive amount of palm wax is difficult to stabilize the fragrance molecules through its own structure. When lotus leaf wax and palm wax are used in combination in the above weight ratio, the synergistic effect of the two is better, and the fragrance release requirements are matched in the mixed system of mild and low-sensitivity fragrances for children's care products, so that the functional additives can exert better application effects.

[0015] Preferably, the weight ratio of the composition A, composition B and glycerol is (0.6-0.8):(0.1-0.3):1.

[0016] By adopting the above technical solution, when composition A, composition B and glycerin in the above weight ratio are used in combination, the three can exert a stable and better effect in the mixed system of mild hypoallergenic fragrance for children's care products, and better improve the fragrance retention time and stability of mild hypoallergenic fragrance for children's care products.

[0017] Preferably, the fragrance solvent is dipropylene glycol.

[0018] By adopting the above technical solution, dipropylene glycol has good co-solubility in water, oil and hydrocarbons. It can not only dissolve and carry fragrance ingredients and distribute them evenly in the product, but also prolong the retention time of the fragrance. At the same time, due to its low volatility and good stability, it can ensure that the fragrance is continuously released during the use of the product.

[0019] In a second aspect, the present application provides a method for preparing a mild hypoallergenic fragrance for child care products, using the following technical solution: A method for preparing a mild hypoallergenic fragrance for child care products comprises the following steps: (1) preparing raw materials including methyl dihydrojasmonate, fragrance solvent, ambergris, musk T, lily of the valley pyran, galaxol stock solution and ethyl linalool according to a proportion; (2) placing the raw materials in step (1) in a stirring container and stirring and mixing them, stirring and mixing them uniformly, and then subjecting the obtained mixed liquid to high-pressure homogenization to obtain a mild hypoallergenic fragrance for child care products.

[0020] By adopting the above technical solution and the above preparation method, the operation process is simple, the production is stable, the obtained product is of excellent quality, the overall applicability is good, and it is suitable for large-scale industrial production.

[0021] Preferably, step (2) is specifically configured as follows: The raw materials in step (1) are placed in a stirring container and stirred and mixed. After stirring and mixing evenly, the obtained mixed liquid is subjected to high-pressure homogenization, and then an emulsifier is added and stirred for pre-emulsification to obtain a semi-finished product. Then, a sodium alginate aqueous solution is added to the semi-finished product and ultrasonically homogenized, and finally the semi-finished product is added dropwise to a calcium chloride solution to obtain a mild hypoallergenic fragrance for child care products.

[0022] By adopting the above technical solution, sodium alginate-calcium chloride microencapsulation forms an ion-crosslinked gel wall material, and the semi-finished product flavor molecules are embedded. During application, the gel wall material is used to soften and gradually release the flavor molecules, thereby significantly improving the fragrance retention time and stability of the low-allergy flavor, and obtaining a mild low-allergy flavor for children's care products with better application quality.

[0023] In summary, this application has the following beneficial effects: 1. This application utilizes a compounding of methyl dihydrojasmonate, ambroxan and musk T to not only synergistically enhance the fragrance persistence, but also delay the release through the macromolecular structure and form a double-layer fragrance fixation system, thereby exerting an excellent compounding synergistic effect, thereby solving the problems of short fragrance retention time and poor stability of existing low-sensitivity fragrances. When the camellia floral fragrance is used in children's care products, it can stably release fragrance and prolong the fragrance retention time. 2. This application uses composition A composed of tea polyphenols and aloe vera gel, composition B composed of lotus leaf wax and palm wax, and glycerin as functional additives, and applies them to mild hypoallergenic fragrances for children's care products, which can significantly improve the stable release of fragrance and extend the fragrance lasting time; 3. This application uses sodium alginate-calcium chloride microencapsulation to embed flavor molecules, which can significantly improve the fragrance retention time and stability of low-allergy flavors, and obtain mild low-allergy flavors for children's care products with better application quality.

[0048] Comparative Example 2 A mild, hypoallergenic fragrance for childcare products is disclosed, which differs from Example 1 in that methyl dihydrojasmonate and musk T are not used in the raw materials.

[0049] Comparative Example 3 A mild hypoallergenic fragrance for child care products is disclosed, which differs from Example 1 in that ambergris and musk T are not used in the raw materials.

[0050] Comparative Example 4 A mild hypoallergenic fragrance for child care products is different from Example 1 in that methyl dihydrojasmonate is not used in the raw materials.

[0051] Comparative Example 5 A mild hypoallergenic fragrance for child care products, which differs from Example 1 in that no ambergris is used in the raw materials.

[0052] Comparative Example 6 A mild hypoallergenic fragrance for child care products is different from Example 1 in that musk T is not used in the raw materials.

[0053] Comparative Example 7 A mild hypoallergenic fragrance for child care products is provided, which differs from Example 1 in that methyl dihydrojasmonate, ambergris ketone, and musk T are not used in the raw materials.

[0054] Performance test samples: The mild hypoallergenic fragrances for child care products obtained in Examples 1-20 were selected as test samples 1-20, and the mild hypoallergenic fragrances for child care products obtained in Comparative Examples 1-7 were selected as control samples 1-7.

[0055] Test method: (1) Hypoallergenic test: 50 volunteers were randomly divided into 25 groups of two people each, half of them were male and half were female. Then, test samples 1-20 and control samples 1-7 were applied behind the ears. If small rashes, itching and other symptoms appeared at the application site (usually within 24 hours), they were immediately rinsed with clean water and recorded. According to the above-mentioned sensitive stimulation within 24 hours of application, the results were recorded in Table 2.

[0056] (2) Fragrance long-lasting stability test: Based on the national standard "GB / T 14454.2-2008 Fragrance Aroma Evaluation Method", 10 sensory evaluators were selected and tested using the triangulation method to ensure that they could quickly and accurately distinguish different aroma concentrations. The sensory evaluators were asked to score the fragrance stability of test samples 1-20 and control samples 1-7 after standing for 10 days on a scale of 1-10. The fragrance lasting time of each sample was also tested and the overall score was scored on a scale of 1-10. The longer the fragrance lasting time, the higher the score. The average of the two scores was taken as the final result, and the results were recorded in Table 2.

[0057] Table 2 Test results of test samples 1-20 and control samples 1-7 Combining Examples 1-3 and Comparative Examples 1-7 with Table 2, it can be seen that the present application can significantly improve the fragrance release stability and durability of mild hypoallergenic fragrances for children's care products by compounding methyl dihydrojasmonate, ambroxan and musk T; however, if any one or two of methyl dihydrojasmonate, ambroxan and musk T are added, the corresponding improvement effect is limited, and the effects of each other can only be simply superimposed. Only when the three are used together can a significant improvement effect of 1+1>2 be achieved, thereby effectively solving the problems of short fragrance retention time and poor stability of existing hypoallergenic fragrances.

[0058] Combining Examples 1 and 4-10 with Table 2, it can be seen that the functional additives composed of composition A consisting of tea polyphenols and aloe vera gel, composition B consisting of lotus leaf wax and palm wax, and glycerin are used in a mild, hypoallergenic fragrance for children's care products, which can further bring about a significant improvement in the stable release of fragrance and the extension of the fragrance retention time. Combining Examples 11-13 with Table 2, it can be seen that if composition A, combination B, or glycerin are added alone, although the corresponding effects can be improved, the improvement is limited, and the sum of the improvement effects brought by the use of the three alone is far less than the excellent improvement effect brought by the combination of the three. It can be seen that the use of the three as functional additives can bring about an excellent compound improvement effect. Combined with Examples 14-17 and Table 2, it can be seen that if only any one of tea polyphenols and aloe vera gel is used in composition A, and only any one of lotus leaf wax and palm wax is used in composition B, it is found that the improvement effect brought by the application of the functional auxiliary agent composed of composition A, combination B and glycerin will be significantly discounted. It can be seen that the combination of the three is irreplaceable and indispensable, so that the excellent performance of the significant compounding effect can be achieved.

[0059] From Example 1 and Example 20 and Table 2, it can be seen that encapsulating the flavor molecules by sodium alginate-calcium chloride microencapsulation can significantly improve the fragrance retention time and stability of the hypoallergenic flavor, thereby obtaining a mild hypoallergenic flavor for children's care products with better application quality.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
