Abstract

1,264,292. Dentifrice compositions. UNILEVER Ltd. 14 May, 1970 No. 23339/70. Addition to 1,186,706. Heading ASB. Dentifrice compositions, particularly toothpastes, contain as a cleansing and polishing ingredient a synthetic, amorphous, porous silica xerogel having an average particle diameter in the range from 2 to 20 microns in an amount sufficient to give the dentifrice a dentin abrasion value of at least 15 units. The silica xerogel may have an average particle diameter in the range 3 to 15 microns, a surface area of at least 300 square metres per gram, e.g. Syloids 73 and 404, and may be the sole or principal cleansing and polishing ingredient preferably constituting from 5 to 50% by weight of the dentifrice. The compositions may also contain a silica thickening agent such as a pyrogenic silica or a silica aerogel, and/or a water-insoluble sodium metaphosphate. The dentifrice may contain various optional ingredients as enumerated in Parent Specification.
