Natural Preservatives for Herbal Shampoo

For preserving herbal shampoo formulations with natural ingredients, several options are suitable. When choosing a preservative, consider the pH range of your shampoo base and the manufacturing process (specifically, if heat is involved).

Here are a few recommended natural preservatives:

• NaturePreserve™ Ultra: This is a natural preservative effective in a pH range of 3-6 and is heat tolerant. It is water-soluble and easy to incorporate.
• Global Guard™ 221: A water-soluble, broad-spectrum natural preservative effective in a pH range of 2-7. It should be added when the formula temperature is below 45°C.
• Coco-Preserve™: Derived from coconut extract, this is a water-soluble, broad-spectrum preservative working in a pH range of 4-8. Avoid heat exceeding 50°C.
• NaturePreserve™ LB2: A natural origin antibacterial agent that is water-soluble and broad-spectrum, effective in a pH range of 2.0-6.5. Avoid heat exceeding 50°C.
• PaeoniaPreserve™: A natural preservative from Paeonia root extract that is soluble in water. Avoid heat above 60°C and add it in the final step of your formulation.

Remember to perform a challenge test on your final shampoo formulation to ensure the chosen preservative is effective at preventing microbial growth in your specific product.
