Bofors toothpaste 1968-1971 In the 1960s, the Swedish weapons manufacturer Bofors tried to branch out and start making so called ‘peace products.’ Like toothpaste, artificial sweeteners and caterpillar tractors. The toothpaste contained plastic beads as a mild abrasive. In 1971, unfounded rumors started about how the plastic beads were toxic. This quickly killed the peaceful toothpaste.
