Abstract: The present invention relates to a solid fragrance composition which can improve the load rate of a fragrant material, can selectively load a fragrance which can be acquired during the aging process of a mixed fragrant material, maintain the fragrance from the beginning of the loading, and improve the longevity of the fragrance at a uniform strength. In addition, the issue of being harmful to the human body can be resolved by reducing powder flying around, and stability at a high temperature can be improved so as to be applied in various environments.

Abstract: The present invention relates to a fragrant material containing aromatic essential oil for improving the retention of the smell and intensity of aroma of aromatic essential oil, and to a method for preparing the same. The fragrant material having long-lasting fragrance according to an embodiment of the present invention contains aromatic essential oil and porous silica loading the aromatic essential oil and having controlled hydrophilicity or hydrophobicity of a surface thereof, wherein the required hydrophilic-lipophilic balance (rHLB) of the aromatic essential oil and the O/C ratio in the porous silica satisfy 0.9?required hydrophilic-lipophilic balance (rHLB) of aromatic essential oil/(O/C ratio of porous silica)?2.9.

Abstract: The present invention relates to a solid aromatic composition capable of significantly improving the loading rate of fragrance substances, selectively loading fragrance that can be acquired during the aging procedure of blended fragrance substances, maintaining fragrance from the early stage of the loading, and improving the persistence of fragrance to have constant intensity. Furthermore, the solid aromatic composition can resolve the problem of harmfulness to the human body by reducing a powder flying phenomenon, and can be applied to various environments by improving high-temperature stability.
