Development of the composition and technology of a cosmetic toothpaste with a low level of abrasiveness for the care of sensitive teeth. In the process of developing and standardizing toothpaste, a set of complementary methods was used. The organoleptic evaluation of the developed cosmetic product was carried out according to the indicators of appearance, color and smell. The hydrogen ion concentration (pH) was determined by potentiometry using a SevenCompact pH meter (Mettler Toledo, Switzerland). The relative abrasiveness index of toothpaste was determined by the original nephelometric method, which is based on determining changes in the turbidity of the surface of polymethyl methacrylate plates in the presence of the test solution and the solution of the reference abrasive, which was prepared in accordance with the requirements of the EN ISO 11609:2017 standard "Dentistry - Dentifrices - Requirements, test methods and marking". The optimal composition of a model toothpaste for the care of sensitive teeth was developed, containing purified water, calcium carbonate, magnesium carbonate, potassium nitrate, CO₂ extracts of chamomile, sage and green tea, sorbitol, xylitol, glycerin, carboxymethylcellulose, cocamidopropyl betaine, polyvinyl alcohol, a preservative based on phenoxyethanol and ethylhexylglycerol, as well as peppermint essential oil. It was established that the relative abrasiveness index to PMMA plates (RPA) of the developed cosmetic product is 31.0 ± 2.5, which corresponds to a low level of abrasiveness. The pH value for the studied sample is 9.0 ± 0.2. Based on the results obtained, a rational technological scheme of industrial production was developed with the definition of critical stages of the process and key quality control indicators. A low-abrasive toothpaste technology based on mineral abrasives combined with functional plant extracts has been developed. The nephelometric method has been used for the first time as a tool for quantitative assessment of the relative abrasiveness of toothpaste, which expands methodological approaches to the standardization of cosmetic products. The developed composition and production technology of toothpaste with a low level of abrasiveness can be implemented in the industrial production of cosmetic products for the care of sensitive teeth.
