Measuring the Effectiveness of a Sol-Gel Matrix in Preserving Essential Oil Concentration

As a common feature of many commercial items such as detergents and personal hygiene products, fragrances are an important aspect of a product\u27s design. In order to preserve the integrity of a fragrance, companies use a variety of techniques to provide a method of controlled release. This project studies the release of fragrances encapsulated within a sol-gel matrix, particularly pure essential oils. Fragrances are analyzed repeatedly in order to study the sol-gel\u27s efficiency in preserving the fragrance over time
