Fragrant material having long-lasting fragrance and method for preparing same |
| 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. |
