Dentifrice compositions having decreased abrasivity and increased cleaning and stain removal properties comprising an abrasive system and about 0.1-2% of a linear high molecular weight polymer selected from the group consisting of polyacrylamide derivatives such as partially hydrolyzed polyacrylamide and double substituted guar gum derivatives such as hydroxypropylated carboxymethylated guar gum.

Dentifrice having decreased abrasivity

The present invention relates to a cosmetic preparation which is particularly effective for providing a cosmetic product that is heated at time of use by the heat of an exothermic reaction, and a process for carrying out such heating.

Self-heating shaving composition

Dentifrice possessing superior cleaning and polishing characteristics containing as the essential ingredients at least one hard abrasive in an amount to provide a radioactive enamel abrasion to the dentifrice of above about 400, such as calcined alumina, zirconium silicate, and the like, and a non-toxic zinc compound in an amount to provide at least about 0.0065% by weight of zinc to the dentifrice.

Modified abrasive system for dentifrices

Liquid scouring compositions possessing enhanced cleaning properties and reduced abrasion characteristics containing as the essential cleaning agent the abrasive calcium metasilicate, stably suspended in an aqueous vehicle.

Liquid scouring cream containing calcium metasilicate

Dentifrice possessing superior cleaning and polishing characteristics comprising a silicious and calcined alumina abrasive system in an amount to provide an enamel abrasion to the dentifrice of above about 450, (as measured by the radioactive method) and about 0.005-1.0% and preferably about 0.1-1.0% by weight of a water soluble fluoride salt, such as sodium fluoride, sodium monofluorophosphate, stannous fluoride and the like, with or without raising the pH of said composition to preferably above about 7 so as to reduce said enamel abrasion thereof.

Reduction of abrasiveness in dentifrices

Dentrifice possessing superior cleaning and polishing characteristics comprising a silicious and calcined alumina abrasive system in an amount to provide an enamel abrasion to the dentrifice of above about 450, (as measured by radioactive method) about 0.1-5% by weight and preferably 1-5% of a calcium, magnesium or sodium salt selected from the group consisting of the carbonates, bicarbonates, chlorides, phosphates, silicates and nitrates, with or without raising the pH of said composition to preferably above about 7, so as to reduce said enamel abrasion thereof.

Reduction of abrasiveness in dentrifices

Dentifrices containing flat flakes of alpha-alumina.

Dentifrices

Dentifrices containing ground crystals of alpha-alumina having a mean ultimate particle size of about 1 to 2 microns. Typically, the size is that essentially 100% are below 10 microns; about 95% are below 5 microns; about 85% are below 3 microns; about 75% are below 2 microns; about 25% are below 1 micron; and about 5% are below 0.5 microns.

Dentifrice possessing enhanced cleaning and polishing characteristics containing as the essential cleaning and polishing agent calcium meta silicate.

Calcium meta silicate as dental polishing agent

Dentifrice possessing enhanced polishing characteristics containing abrasive system including at least calcium pyrophosphate and a non-toxic zinc compound in an amount to provide at least about 0.0065% of zinc to the dentifrice.

Calcium pyrophosphate abrasive system for dentifrice

Dentifrices containing flat flakes of alpha-alumina

Toothpaste formulations having dispersed therein an invisible abrasive material and visible abrasive agglomerates are disclosed. The abrasive agglomerates comprise subparticles of hard abrasive materials (Moh hardness of at least about 5) joined together by a binding agent material, and provide increased cleaning and polishing characteristics as well as an attractive speckled appearance to the toothpaste formulation.

Abrasive agglomerates of abrasive subparticles and binder material

A dental cream comprising a dental vehicle a small portion of flat flakes of alpha-alumina and a small proportion of iridescent flakes. The vehicle preferably has dispersed therein amorphous silica or aluminosilicate as a dental abrasive.

Dental polishing creams

There is disclosed a toothpaste containing dispersed particles of sodium bicarbonate and a polishing agent composition comprising titanium dioxide powder having a particle size less than about 2 microns, the amount of titanium dioxide powder being about 0.1 by weight on the weight of the toothpaste and a method of making same.
