Intelligent deodorant

Our Rexona deodorant uses body-responsive micro-capsule technology that kicks in when it’s needed most, giving people the confidence to face the day's more stressful situations.

The challenge

Instances of stress – whether expected or unforeseen – can make people sweat more than usual. However, at times like these most deodorants can’t cope. Our challenge was to develop a product that offered extra protection at such moments, delivering additional freshness and giving consumers the confidence that comes from knowing they look in control.

Understanding sweat

The key to solving the issue lay in understanding sweat. Our studies showed that humans produce two quite different types: physical sweat that the body makes when it’s hot, and sweat that breaks out in moments of stress, anxiety or high emotion. Unlike physical sweating, emotional sweating occurs predominantly on the hands and armpits. This type can produce up to five times more sweat than the physical kind and can smell more unpleasant. Physical sweat takes five to ten minutes to occur; emotional sweat can be instantaneous.

Responsive technology

Since deodorants deal primarily with physical sweat, we set about developing a technology that could also cope with emotional sweat. In partnership with key suppliers, our scientists developed a new anti-perspirant – Rexona Activreserve – whose special micro-capsules of odour protection are activated when the body responds to stressful situations.

These capsules sit on the skin’s surface. When pressure or stress cause a sudden, uncontrollable burst of sweat in the underarms, the sweat dissolves the capsules giving extra odour protection when it’s most needed. So whether an individual is sweating a lot or a little, the technology will always release the right amount of protection.

Putting it to the test

Using assessors who are trained to sniff body odour and rate its intensity and character, we demonstrated that Rexona Activreserve continues to reduce odour up to 24 hours after it’s applied, even with multiple stressful moments during the day.
