Dentrifrice Comprising MVE Copolymer, Lactic Acid, Fluoride
Summary
USPTO published patent application US20260108434A1 for a dentifrice composition containing a copolymer of MVE with maleic acid (0.9–1.1% by weight), lactic acid or alkali metal salt (1–4% by weight), and a fluoride ion source. The composition is mildly acidic with a slurry pH of 5.0–6.5 and is designed to enhance fluoride uptake into teeth and provide protection against acidic challenges. The application was filed on December 10, 2025, with application number 19414831.
“A dentifrice composition is described comprising a copolymer of MVE with maleic acid; lactic acid or alkali metal salt thereof; and a source of fluoride ions, wherein the copolymer is present in an amount of range 0.9% to 1.1% by weight of the total composition; wherein the lactic acid or alkali metal salt thereof is present in an amount of 1% to 4% by weight of the total composition, wherein the dentifrice composition is mildly acidic, having a slurry pH in the range 5.0 to 6.5.”
About this source
USPTO classification A61K covers pharmaceutical preparations: formulations, dosage forms, combination therapies, delivery systems, and the vehicles that carry active ingredients. Every newly published application in A61K lands in this feed, around 245 a month. Applications publish 18 months after filing, so this feed reveals what pharma formulators at major sponsors and generics were working on in the prior year and a half. Watch this if you compete in drug formulation, file freedom-to-operate analyses, scout competitive drug products before clinical readouts, or follow novel delivery platforms like nanoparticles, lipid carriers, and long-acting injectables.
What changed

Abstract
A dentifrice composition is described comprising a copolymer of MVE with maleic acid; lactic acid or alkali metal salt thereof; and a source of fluoride ions, wherein the copolymer is present in an amount of range 0.9% to 1.1% by weight of the total composition; wherein the lactic acid or alkali metal salt thereof is present in an amount of 1% to 4% by weight of the total composition, wherein the dentifrice composition is mildly acidic, having a slurry pH in the range 5.0 to 6.5. The composition enhances fluoride uptake into teeth and provides protection against acidic challenges.
