Improving Fragrance Longevity in Lotion

It's common for fragrances to smell strong in the product but fade quickly on the skin, especially in water-based formulations. This is because the volatile fragrance molecules evaporate from the skin surface.

To help your lotion's fragrance last longer on the skin, you can consider adding ingredients that help "fix" or retain the scent. Here are a couple of approaches:

• Use a Fragrance Encapsulation Technology: Encapsulation involves trapping the fragrance molecules within a protective shell. This prevents them from evaporating too quickly and allows for a slower, more sustained release of the scent on the skin. An example of this technology is AromaLock™.
• Add a Film Former: Film formers create a thin, often invisible, layer on the skin. This film can help to physically trap the fragrance molecules, reducing their evaporation rate and keeping the scent on the skin for a longer period. Comfort Film is a water-based film former suitable for lotions that can help improve product durability on the skin, which in turn can help with fragrance longevity. You can add Comfort Film to the water phase of your formula. The typical usage rate is 5-50%, so you could start with a lower percentage (e.g., 5-10%) and adjust as needed.
• Slightly Increase Fragrance Concentration: While not a primary solution for longevity, a slightly higher concentration of fragrance (within safe limits) might make the scent more noticeable for a longer time. However, focus on encapsulation or film formers for true longevity improvement.

Consider adding either an encapsulated fragrance product like AromaLock™ or a film former like Comfort Film to your existing formula to help the beautiful scent last longer on your skin after application.
