Unilever’s scientists have developed a unique toothpaste which combines a warming sensation that battles bad breath with long-lasting, cooling freshness.
The secret of Close Up Fire-Freeze toothpaste’s revolutionary formula lies in its range of novel ingredients and the expertise of Unilever’s R&D specialists.
The Fire-Freeze sensation
Brushing with the red and blue gel offers an experience quite unlike any other toothpaste.
Fire-Freeze first delivers a mild, warm tingle while it cleans, thanks to chemosensory technology and extracts including eugenol, an oil found in cloves.
The heat then builds from a blend of aromatic spices and wintergreen, also known as methyl salicylate, a plant-derived product with a natural warming ability.
From hot to cold
Next comes an intense hit of icy freshness, a sensation Unilever scientists were determined to make last long after brushing.
The Fire-Freeze formula uses a patented technology – the longest-lasting cooling agent on the market – which offers up to ten times the power of other cooling molecules.
Zinc sulphate, an anti-malodour active which provides up to 12 hours of fresh breath, ensures the cool feeling lasts for hours. And a blend of menthol, peppermint and vanilla adds the finishing touch to the unforgettable flavour.
Results indicate that using Close Up Fire-Freeze over four weeks reduces malodour significantly compared to a conventional gel toothpaste.
Close Up Fire-Freeze launched in Brazil, India and the Philippines in 2011.
