Preservatives for Mouth Spray

For mouth spray formulations, it's important to choose preservatives that are safe for oral use, water-soluble, and effective against bacteria, particularly those causing odor.

• Cetylpyridinium chloride (CPC): This ingredient is commonly used in oral care products, including mouth sprays and mouthwash, specifically for its ability to act directly on odor-causing bacteria. It also functions as a preservative in cosmetic formulations. It is water-soluble.
• Mild Preserved™ COS: This is a broad-spectrum, water-soluble preservative that is odorless and effective over a wide pH range (2-8). It can be a good general-purpose option if an odorless preservative is preferred.
• Eye Preserved™ (Polyhexamethylene Biguanide, PHMB): While developed for sensitive areas like around the eyes, it is gentle and can kill odor-causing bacteria. It is water-soluble and works in a pH range of 3-8 (recommended 3-6.5).
• NaturePreserve™ Ultra (Gluconolactone & Sodium Benzoate): A natural, water-soluble preservative effective in a pH range of 3-6.
• Global Guard™ 221: Another natural, water-soluble, broad-spectrum preservative effective in a pH range of 2-7.
• Preserve-BSB™: A water-soluble preservative effective up to pH 5.5.
• NaturePreserve™ LB2: A natural, water-soluble anti-bacterial agent effective at low pH values (2.0-6.5).

When selecting a preservative, consider the specific pH of your mouth spray formulation and any desired claims (e.g., natural). Always perform a challenge test to ensure the chosen preservative is effective in your final product formulation.
