GlaxoSmithKline has introduced a new toothpaste delivery system that disperses active ingredients quickly, penetrating hard-to-reach areas of the mouth, according to the company.
Iso-active, which is available in the company's Aquafresh and Sensodyne products, is delivered in a canister with a gel-to-foam action. The toothpaste is dispersed from the canister as a gel and turns to foam in the mouth as a result of an ingredient called isopentane, GlaxoSmithKline said.
Isopentane responds to temperature increases caused by the warmth of the mouth. A relatively small increase in temperature causes the isopentane ingredient to evaporate, stimulating the product's foaming action.
"The rich active foam that is produced when iso-active reacts with the warmth of the mouth is a new technology never used before in the oral healthcare category," said David Urquhart, principal scientist of new product development at GlaxoSmithKline, in a press release.
