Ingredients to Help Fragrance Last Longer in Liquid Soap

Making fragrance last longer on the skin from a wash-off product like liquid soap can be challenging as the fragrance tends to rinse away. However, there are ingredients and technologies that can help improve fragrance longevity.

Two approaches you can consider are using a fragrance fixative or utilizing fragrance encapsulation technology.

• Fragrance Fixative: An ingredient like Encap Shampoo (which is actually a fragrance fixative, not a shampoo) can be used. Its chemical name is 2-tert-butylcyclohexyl acetate. It helps to prolong the life of other fragrances when added to the formulation. It is typically used at a low concentration, such as 0.1%.

• Fragrance Encapsulation: A more advanced method for wash-off products is fragrance encapsulation, such as the AromaLock™ (Fragrance Encapsulation Service). This service encapsulates your chosen fragrance into a water-soluble powder. This encapsulated form helps the fragrance adhere better to the skin during washing and allows for a more sustained release of scent, making it last longer after rinsing. This technology is specifically designed for products like shampoos, conditioners, and skin cleansing products to enhance fragrance retention on the skin.

Choosing between these options depends on your desired performance and formulation complexity. Encapsulation generally offers superior performance for wash-off products but involves a service rather than a direct ingredient purchase.
