ABSTRACT:
This invention relates to toothpaste containing an alumina hydrate abrasive and flavoring.
According to the invention, there is provided a toothpaste containing flavoring and unmilled, precipitated alumina trihydrate as an abrasive, wherein the alumina trihydrate particles have a median particle size of at least 3 micrometers.
The median particle size of the alumina trihydrate is preferably below 30 micrometers, more preferably from 5 to 20 micrometers, and most preferably 8 to 12 micrometers.
It has been found that the use of an unmilled alumina trihydrate, obtained by precipitation, reduces the amount of flavoring material required to obtain a given flavor strength when compared with an equivalent content of milled alumina trihydrate of similar particle size.
