A study of 84 homemade toothpaste recipes and the problems arising from the type of product

Abstract

Objective Growing consumer mistrust of a number of ingredients used in industry has led to the development of a trend for homemade products. This now affects all types of sectors, but particularly the hygiene sector for shampoo and toothpaste products. The aim of this work is therefore to study recipes found on the internet for these types of products in order to assess risks associated with their use.

Materials and methods Eighty-four recipes were collected from the internet and their composition was analysed.

Results None of the 84 formulas analysed contained any fluoride salts, well known for their oral health benefits. Eighty percent did not contain a foaming agent either, which is very useful in the cleaning function of toothpastes. Furthermore, the quantities of substances to be used were usually expressed in tablespoons or teaspoons, measures which are imprecise and could, for example, lead someone to use large quantities of an abrasive agent such as calcium carbonate.

Conclusions Attention should be drawn to homemade toothpaste recipes that contain no fluoride and whose abrasivity, purity and microbial contamination cannot be verified.

Key points

  • Shows that homemade toothpaste recipes can be dangerous.

  • Highlights that none of the formulas analysed contained any fluoride salts.

  • Highlights that it is impossible to predict their abrasiveness and microbiological quality.
