Abstract: Non-cariogenic sugar composition comprising 2 to 10 ppm fluoride, and preferably 50 to 400 mg/100 g each of calcium ion and phosphate (calculated as P) and 5 to 50 mg/100 g magnesium. The composition is made by blending a composition deficient in fluoride ion with a composition superabundant in fluoride ion, preferably obtained by selection of a superabundant fluoride ion containing fraction of cane sugar containing molasses, such as raw cane sugar, molasses, affination syrup, dried solids of molasses or of affination syrup or a blend thereof with refined sugar, or by evaporation of a mineral water to obtain a concentrate.

Abstract: Continuous production of aluminum hydroxycarbonate gel by continuous reaction of aluminum salt solution with mixed alkaline carbonate and bicarbonate solution under homogeneous conditions in a relatively small reaction vessel, and continuing the reaction in a subsequent reaction vessel under controlled pH. The product gel is separated from the non-aluminum cation containing reaction mixture within less than about 6 hours, whereby formation of poorly soluble addition reaction products such as dihydroxy aluminium sodium carbonate, which contribute undesired non-aluminum cations to the gel product, is reduced. The aluminum salt solution is adjusted in pH by adding to it a portion of the mixed carbonate and bicarbonate solution to obtain a clear solution of pH 3.5 to 4.0. This results in a smooth, creamy gel with less objectionable chalky mouth feel.

Abstract: Dental hygiene compositions containing as antiplaque/antiseptic/deodorizing active ingredient highly pure alkali metal lauryl sulphate substantially free from non-lauryl alkyl salts.

Abstract: Aluminum hydroxycarbonate gel is precipitated under highly homogeneous conditions by continuously introducing an aluminum salt solution and an alkaline-reacting carbonate and bicarbonate solution into a vigorously agitated reactor vessel and continuously withdrawing the reaction mixture.
