Scientists develop first ever perfume that makes you smell better the more you sweat

Wouldn’t it be great if the more you worked up a sweat the less you would have to worry about social awkwardness and the better you would smell? Well thanks to a new development at Queen's University Belfast this could become a reality.

The team of scientists have developed the first-ever perfume delivery system to ensure the more a person sweats, the better they will smell, as more of its aroma will be released when it comes into contact with moisture.

Researchers in the Queen's University Ionic Liquid Laboratories (QUILL) Research Centre developed the unique new perfume delivery system which makes it so a person smells nicer when their sweat levels increase, and published its study in the journal Chemical Communications.

“This is an exciting breakthrough that uses newly discovered ionic liquid systems to release material in a controlled manner,”​ says project leader, Dr Nimal Gunaratne, from the QUILL Research Centre.

“Not only does it have great commercial potential, and could be used in perfumes and cosmetic creams, but it could also be used in others area of science, such as the slow release of certain substances of interest."

‘Perfumed ionic liquid’

This innovative perfume system works by tagging a raw fragrance onto an ionic liquid (salt in the form of liquid) which has no smell. The 'perfumed ionic liquid' releases its aroma when it comes into contact with water, allowing more of the perfume's scent to be released onto a person's skin.

In addition, the perfume system also has the ability to remove the bad odours that come from sweat. The 'thiol' compounds that are responsible for the malodour of sweat are attracted to the ionic liquid, attaching themselves to it and losing their potency.

The breakthrough could have major commercial possibilities, potentially providing a new way to develop products for the huge personal care market.

QUILL researchers are currently working with a perfume development company to identify a number of product ideas that could eventually be sold in shops.

"This innovative development demonstrates the drive of researchers at Queen's to advancing knowledge and achieving excellence for the benefit of society as a whole,"​ adds Gunaratne.
