CITROCOAT® EP

Introduction

CITROCOAT® EP is an agglomerated effervescent compound, bringing citric acid and sodium bicarbonate together in the right composition to create a highly reactive but storage-stable effervescent powder with a target pH of 5.5. Due to the excess acidity, a rapid effervescent reaction is to be expected, and the slightly acidic pH value ensures a fresh flavour. In order to prevent premature reactions, the citric acid used in CITROCOAT® EP is coated with a thin layer of monosodium citrate. The two effervescent components are agglomerated using a binder, reducing the potential for segregation and improving compressibility. This leads to significantly harder tablets than with a formula based on regular citric acid and sodium bicarbonate.
