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

    摘要： This invention relates to toothpaste containing an alumina hydrate abrasive and a source of fluoride.
    According to the invention, there is provided a toothpaste containing a source of fluoride ions and unmilled, precipitated alumina trihydrate as an abrasive, wherein the alumina trihydrate particles have a median particle size of at least 3 micrometres.
    The median particle size of the alumina trihydrate is preferably below 30 micrometres, more preferably from 5 to 20 micrometres, and most preferably 8 to 12 micrometres.
    It has been found that the use of an unmilled alumina trihydrate, obtained by precipitation, substantially reduces the loss of available fluoride on storage whereas the use of a milled alumina trihydrate causes significant loss of available fluoride.
