Hi my dear friends , we like this colgate active salt tooth paste. Bcoz it is a number one brand in the market and good quality totally. Once upon a time our people used to for cleaning teeth, charcoal with salt . that same process this cogate people are useing. So our fore fathers knows the formula. So again with this colgate people are useing the same formula. So here old is gold. And this colgate active salt peole are useing mostly like 3: 1 familys friends. So largest selling in the market because of salt mixeing.
