Radiant colours and sophisticated colour changes with Iragon® and Puricolor®

Standing out from the crowd by means of visual effects is becoming increasingly important, particularly in the home care and personal care sectors. This can be achieved, for example, by using a slight fluorescent sparkle or a colour change. With its Puricolor® and Iragon® product lines, BTC offers a series of dyes that are particularly suited for various applications. “There are a number of interesting applications which use colour changes to indicate that a product is effective,” says Gisela Herzog, Marketing & Sales Manager Europe for Colorants Home and Personal Care. 

Colour-changing toothpaste and cleaning products

Indicator dyes can be used in a variety of applications, such as in toothpaste that changes its colour to indicate that the teeth have been brushed long enough, or in cleaning products that change colour depending on the pH value. This makes it possible to identify places that are still need cleaning – in a way, the product thinks for itself. Other options include colour-changing bubble baths or toilet cleaners.

Fluorescent: radiant signal colours

If you wish to create a real eye-catcher or highlight a particular product claim, you can also use fluorescent colours – such as in shower gels that are advertised as providing extraordinary vitality or refreshment, or in personal care products targeted at young people. “The many specific queries by our customers clearly show that fluorescent colours are back in vogue,” says Herzog.

Colour strength for strong colours

All dyes of the Puricolor® and Iragon® series have one thing in common: their high colour strength is truly impressive. “This is something that really sets us apart in terms of quality,” says Herzog. At the same time, the large number of different colour shades enables customers to mix their very own personal colour, either by relying on their own formulation know-how or by taking advantage of the solid experience of the BTC experts.
