Important Note

  • The concentration & volume of sodium hydroxide solution can be adjusted according to your in-house requirements.
  • The concentration and volume of food-grade detergent can also be adjusted according to requirements.
  • In place of sodium hydroxide solution, you can use any basic detergent which is validated for your cleaning process.
  • We use basic detergent or Sodium hydroxide solution because enteric coating polymers are removed by basic solutions.
