Abstract: A paint or varnish composition is described which comprises a medium, such as an alkyd resin, and an anticorrosion agent which is environmentally non-hazardous and soluble or adapted to be soluble in the medium. The composition is suitable for application to a metal substrate and the anticorrosion agent is selected so as to enable a dry paint or varnish film to be obtained on the metal substrate, preferably within 24 hours from the time of application.

Abstract: 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 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, substantially reduces the loss of available fluoride on storage whereas the use of a milled alumina trihydrate causes significant loss of available fluoride.

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.
