Description

Technical Field

[0001] This invention belongs to the field of fragrance technology, specifically relating to a detergent fragrance containing lavender extract and its application. Background Technology

[0002] Fragrance is an artificially formulated mixture containing two or more, even dozens, of fragrance ingredients, possessing a specific aroma. The main raw material used in fragrance formulation is aromatic essential oil, which has functions such as pain relief, anxiety reduction, and hypnosis, and is widely used in detergents, cosmetics, textiles, food, and pharmaceuticals. However, fragrance molecules are unstable, highly volatile, and easily oxidized, greatly limiting their applications. If used directly on textiles, the fragrance's duration is very short. Furthermore, most detergent fragrances currently on the market suffer from poor aroma and antibacterial effects. Therefore, providing a fragrance that solves these problems is of great practical significance. Summary of the Invention

[0019] An application of a detergent fragrance containing lavender extract, wherein the detergent fragrance is added to the detergent at a weight percentage of 1-3%.

[0020] The beneficial effects of this invention are:

[0021] Component A of this invention is a blend of juniper fruit oil, sage essential oil, magnolia oil, and lavender essential oil, which enhances the fragrance of the detergent, making it pleasant and rich in aroma, while also having the effects of balancing the mind and body, calming the nerves, and soothing the nerves. Specifically, the main components of juniper fruit oil are limonene, α-pinene, and β-myrcene, which can suppress anxiety by inhibiting sympathetic nerve activity and enhancing parasympathetic nerve activity, thereby reducing respiratory rate and heart rate to some extent. In addition, sage essential oil, with its strong and refreshing aroma and rich in α-pinene and α-thujone, assists juniper fruit oil in soothing the parasympathetic nervous system and preventing fatigue caused by excessive parasympathetic nerve activity. Furthermore, this application also adds magnolia oil, which is rich in methyl methylbutyrate, linalool, and cis-linalool oxide, with linalool exhibiting a significant central nervous system sedative effect. Lavender essential oil, with its long-lasting and gentle aroma, relieves fatigue and soothes, thereby harmonizing the body's balance and promoting relaxation. Therefore, the four essential oils added in this invention—juniper fruit oil, sage essential oil, magnolia oil, and lavender essential oil—can work synergistically to give the resulting detergent fragrance excellent effects of balancing the mind and body by inhibiting sympathetic nerve activity, soothing the parasympathetic nervous system, calming the central nervous system, and relieving fatigue.

[0022] (2) The juniper fruit oil added in this invention has a strong inhibitory effect on Bacillus subtilis, Staphylococcus epidermidis and Staphylococcus aureus; the added spikenard essential oil mainly contains spikenardone, terpinene, aristolochnine and spikenard alcohol, which have a strong bactericidal effect on Escherichia coli and Staphylococcus aureus; the added perilla seed oil is rich in L-perillaldehyde, and also contains isoperillone, trans-limonene and perillone, which have a broad-spectrum antibacterial effect and also have the functions of preservation and fragrance enhancement. Therefore, it can assist the juniper fruit oil and spikenard essential oil to jointly enhance the antibacterial effect of component B, and at the same time promote the release of a rich aroma of component A, further making the obtained detergent fragrance have an outstanding antibacterial effect.

[0023] (3) This invention uses a complex of hydroxypropyl-β-cyclodextrin and sodium alginate as the inner wall material and gum arabic as the outer wall material. Montmorillonite is added to the inner wall material to increase its density, which hinders the release of essential oils encapsulated by the wall material and reduces their release rate. The resulting double-encapsulated detergent fragrance provides better protection for the essential oils and solves the problem of easy volatilization and short fragrance retention time after the essential oils are simply mixed with other detergent components. At the same time, it also makes the finished fragrance product have a long-lasting and slow-release effect, effectively improving the stability of the detergent fragrance. Detailed Implementation

[0082] Test Example 1

[0083] (1) Fragrance richness and comfort test: Cotton cloth (specification 20cm*20cm) was ultrasonically cleaned for 10min each with distilled water, anhydrous ethanol and distilled water, and then dried in a ventilated place to remove the impurities remaining in the cotton fibers. Then, the cotton cloth after removing the impurities was immersed in the detergent products prepared in Examples 1-3, Comparative Examples 1-4 and Comparative Examples 8-10 respectively in a constant temperature water bath at 30℃ for 1h, and then dried at room temperature.

[0084] A sensory evaluation panel composed of 12 professional sensory evaluators immediately conducted sensory evaluations on the soaked cotton fabric to test its aroma and calming effects. The sensory evaluation used a 5-point scale; a higher score indicated better overall aroma comfort and calming effects after the cotton fabric was soaked. The average score from the sensory evaluation panel was taken as the final score. Descriptions of each characteristic and scoring criteria are shown in Table 1, and the final results are shown in Table 2.

[0085] (2) Slow-release performance test: After the cotton fabric tested in (1) above was placed for 14 days and 28 days, a sensory evaluation group composed of 12 professional sensory evaluators who evaluated the cotton fabric tested in (1) above was invited to evaluate the cotton fabric again using the same standards in Table 1. The average value of the sensory evaluation group was taken as the final score value. The final results are shown in Table 3, which reflects the slow-release performance of the product. The higher the final score value, the more durable the product is and the better the slow-release performance.
