Water-based air-freshener gels are replacing traditional organic solvent-based gels, making them environment-friendly. A water-based gel was prepared in this study. The gel contains perfume ingredients and water that vaporizes over a period of time. In order to characterize the rate of fragrance dissipation, thermal analysis was used. The loss of functional characteristic was studied using an accelerated program employing thermogravimetry and derivative thermogravimetry. The DTG plot showed the disappearance of the perfume ingredient as the gel was heated. Water-based gels were prepared in this way and characterized.
