As we all know, the reason why aromatherapy has a beautiful aroma is because it contains essence and flavor. When perfumers prepare fragrances, they need to consider the fragrance retention, so they use fixatives. The purpose of the fixative effect is to prolong the individual spices in the essence The volatilization time limit of the components also allows the aroma characteristics or fragrance of the essence to remain stable and long-lasting. Perfume fixative changes the vapor pressure, viscosity, and relative humidity of the essence. Molecular mass, solubility, molecular attraction and other methods can be used to improve the fragrance retention of the entire fragrance. Because of the addition of fixative, there is electrostatic attraction and hydrogen bonding between the molecules of the fragrance, etc. Changes occur, resulting in a reduction in the vapor pressure of the essence, slowing down the evaporation rate, thereby achieving the purpose of retaining fragrance. In some cases, with the addition of fixative, the threshold concentration of spices in the essence is reduced, changing the viscosity of the essence, thereby extending the time limit of being smelled. Moreover, there is not only one type of fixative. Different fragrance needs require different ingredients in the fixative. The role of fixative is like a child holding on to a rapidly rising balloon, preventing the balloon from breaking free and rising freely. The same is true for aroma. The fixative captures those volatile aroma elements and enhances the fragrance retention of the entire essence.
Its function: The volatile liquid of fire-free aromatherapy aroma products is also used as a solvent for aroma products and a fixative for daily fragrances. This is the purpose of aromatherapy requiring dipropylene glycol methyl ether.
Fragrance Fragrances are widely used in aromatherapy, home accessories, sachets, car perfumes, air fresheners, aromatic essential oils and dried flowers. It is an indispensable and important raw material for high-quality human life in modern society, and its market size is also on a growing trend. For example, triethanolamine can be used to prepare cosmetic balms.
