Global Guard™: Food Grade Status and pH Suitability for Preservation in Cream
คำถาม
I have questions about Global Guard™.
- If it can be used in products that go into the mouth, does that mean it is food grade?
- If the cream is at
pH 5.4, is it still usable? I intend to use it as the only preservative in the formula.

Global Guard™ Usage and pH Suitability
Regarding your questions about Global Guard™:
Is Global Guard™ food grade?
The description for Global Guard™ mentions that it is highly preferred for oral care products because its main components, Sodium Benzoate and Potassium Sorbate, are well-known for their use in food. While these components are food-approved and the product is suitable for oral care, the description does not explicitly state that Global Guard™ itself is classified as "food grade".Is pH 5.4 suitable for Global Guard™ as a sole preservative?
Yes, a pH of 5.4 is suitable for the effectiveness of Global Guard™. The product is effective in formulations with a pH between 2.0 and 5.5. However, whether it is sufficient as the only preservative in your specific cream formulation requires a challenge test to confirm its efficacy against microbial growth in that particular product.
