Stabilized Nasal Aroma Stick Containing Natural Essential Oils

Abstract

This invention relates to a nasal aroma stick that provides controlled aroma release to be perceived through the nose. Within the scope of the invention, aromatic components consisting of menthol and at least one natural essential oil are impregnated into an absorbent carrier structure, which is then housed within a closed body. The menthol is stabilized using a water bath method, and the aromatic mixture of stabilized menthol and essential oils is released evenly and over time through the absorbent carrier structure. The invention encompasses formulations with different aroma profiles, each containing menthol-dominant, intensely cooling, citrus-based, floral or woody, and herbal notes, with specific ratios of menthol and various natural essential oils. This structure prevents the rapid evaporation of aroma components, ensuring a consistent and controlled aroma experience throughout the usage period.

Description

Stabilized Nasal Aroma Stick Containing Natural Essential Oils Technical Area This invention aims to provide a feeling of freshness through aromatic components perceived via the nose. products in this field, especially those containing natural essential oils and stabilized menthol, It refers to nasal aroma sticks that provide controlled and long-lasting aroma release. The invention relates to the physical stabilization, controlled evaporation, and absorbent properties of menthol and essential oils. It includes technical solutions for releasing signals from a carrier system. State of the Art Prior to the invention, products developed to provide a feeling of freshness through the nose were generally... nasal sprays, drops, inhaler sticks and similar aromatic application devices These products consist mostly of menthol, eucalyptol, and similar volatile substances as active ingredients. The components used are generally alcohol, glycol or similar. It is presented to the user after being dissolved in chemical solvents. In current nasal sprays and drops, menthol and essential oils are in the liquid phase. It is present within the system and evaporates rapidly after application. This situation, It creates a short-term and immediate effect; however, in terms of duration of effect, it offers sustainable performance. This is not possible. Furthermore, the chemical substances used as solvents in such products have a long lifespan. Prolonged or frequent use may cause undesirable effects such as dryness, sensitivity, and irritation of the nasal mucosa. It can lead to various effects. In inhaler sticks and similar solid-form products, menthol and aromatic components are usually present. It is used by being absorbed into an absorbent wick or carrier material. However, in these products Menthol is usually found in unstabilized crystalline form or dissolved in solvents. Because of its presence, crystallization, decomposition, or irregular evaporation may occur over time. Problems arise. This situation is related to the aroma intensity during the first use of the product. This leads to a widening gap between subsequent uses and affects the user experience. It has a negative impact. In previous technical products, the volatility characteristics of menthol were not sufficiently controlled. It cannot be obtained. Menthol, due to its high volatility, is especially important at high temperatures. It is sensitive to changes, and this can lead to sudden and uncontrolled aroma release. This causes the aroma intensity in existing products to decrease rapidly. 35 loses its effect quickly. 1 In some applications, synthetic binders or additives are used to improve the stability of menthol. Chemical stabilizers are used. However, these types of additives do not affect the natural content of the product. This weakens its perception and reduces its desirability among users. Furthermore, this type of Aroma profiles in these systems are limited, with menthol exhibiting a dominant character and being volatile. It becomes difficult to perceive the fats in a balanced way. In the perfume and fragrance industry, the stabilization of menthol crystals is achieved using the water bath method. Several techniques are known for this purpose. These techniques aim to make menthol acquire a more homogeneous structure. and aims to ensure controlled evaporation. However, these methods are mainly It is limited to the production of perfume raw materials or cosmetic applications; nasal in portable products designed for use with a controlled oscillation mechanism It is not being implemented. Also in existing technical solutions, in products where menthol and essential oils are used together. A holistic approach to ensuring long-term and balanced aroma release. It is not available. The products generally either produce a short-lived intense effect or have a low menthol content. When reduced, it does not provide a sufficient feeling of freshness. In conclusion, the previous technique addressed the stability of menthol, the control of aroma release, and the duration of effect. technical aspects of extending and developing formulations focused on natural ingredients. It has limitations. This situation applies to stabilized products that use menthol and essential oils together. There is a clear need for a new technical solution that provides controlled and long-lasting aroma release. It reveals. The invention, application number 2020 / 09419, describes a nasal device that prevents allergic reactions. It is a compound and differs from this invention. Purpose of the Invention The primary aim of this invention is to provide a feeling of freshness through aromatic components perceived via the nose. stability, duration of effect and ease of use encountered in products aimed at providing this. The aim is to offer a technical solution to their problems, especially regarding existing products containing menthol and essential oils. Uncontrolled evaporation observed in the products, short-lived effect, and irritation due to chemical solvents. The aim is to eliminate the risks. Another aim of the invention is to stabilize the physical structure of menthol crystals over time. The aim is to prevent undesirable situations such as crystallization, precipitation, or decomposition. In this way... The volatility characteristics of menthol are controlled and remain consistent throughout the product's shelf life. An aroma profile is provided. 35. The invention also describes the balanced and controlled preparation of aromatic mixtures composed of natural essential oils. 2 It aims to develop a system that makes its release possible. Thanks to this system, the aroma Instead of a sudden and intense impact, the release is spread over time and is more balanced for the user. It takes place in a way that will offer an experience. Another aim is to reduce the need for synthetic solvents and alcohol-based carriers by using natural ingredients. The goal is to obtain a nasal aroma product that is focused on, highly user-friendly, and hygienic. This approach both improves the user experience and adapts the product to different user preferences. It increases its adaptability. Finally, this invention is presented in a portable, enclosed, and mass-production-suitable structure. An innovative product that combines stabilized menthol and essential oils, providing controlled release. It aims to offer a nasal aroma stick. Description of the Invention The invention involves a blend of natural essential oils containing stabilized menthol with controlled aroma release. This is a nasal aroma stick that provides a unique scent. The product contains stabilized menthol and optimized volatile oils. Oil formulations consist of an absorbent carrier system and a closed body structure. This The elements work together to produce a balanced, long-lasting, and controlled aromatic composition. It allows it to be released. 1. Water Bath Stabilization of Menthol Within the scope of the invention, menthol crystals are processed using the water bath method within a specific temperature range. It is stabilized by processing. During this process, the structure of menthol crystals is homogenized. and intracrystalline stresses are reduced. Thus, the volatility behavior of menthol is improved. It is becoming predictable and controllable. The water bath stabilization process prevents menthol from crystallizing and separating over time. or irregular evaporation is prevented. This ensures that the product maintains a similar concentration with each use. This technique also makes it possible to release aroma. Furthermore, this technique allows menthol to be directly released into solvents. It offers a more stable and sustainable structure compared to dissolving it. This stabilization method, while adapted from known perfume technologies, is nasal. In terms of use with aroma sticks and controlled release systems, it was the previous It deviates from the technical aspect. 35 3 2.
