Preservatives for Herbal Body Scrub

To ensure your herbal body scrub containing ingredients like turmeric, 'prai' (ginger/related), 'din sor phong' (clay), and water remains stable and free from mold and spoilage for a long shelf life, the most crucial factor is the quality and cleanliness of your raw materials.

As discussed previously, it is essential to use cosmetic-grade ingredients for all components, especially natural materials like turmeric, 'prai', and 'din sor phong'. Food-grade ingredients often have higher microbial loads that standard cosmetic preservatives cannot effectively control over time.

Once you have ensured all your raw materials are cosmetic-grade and you have created your scrub formulation, the next step is to measure the final pH of your product. The effectiveness of a preservative is highly dependent on the pH range of the formula.

Here are some examples of cosmetic-grade ingredients and broad-spectrum preservatives that might be suitable, depending on your formula's pH:

• Herbal Ingredients:
  • For Turmeric, cosmetic-grade extracts like WhiteCumin™ 2x (a liquid form of Tetrahydrocurcuminoids) or Turmeric Extract Curcumin Yellow Color (Natural Colorant) (a water-soluble powder) are available.
  • For 'Din Sor Phong', cosmetic-grade clays such as Kaolin (China Clay) or Green Clay can be used.
• Preservatives:
  • Mild Preserved™ COS is a broad-spectrum, odorless liquid preservative effective in a wide pH range of 2-8.
  • NaturePreserve™ Ultra (Gluconolactone & Sodium Benzoate) is a natural powder preservative effective in a pH range of 3-6.
  • NaturePreserve™ LB2 is a natural origin liquid preservative effective at lower pH values (2.0-6.5).

After measuring the pH of your finished scrub, you can select a preservative that works optimally within that specific pH range.

Important Note: Before selling your product, it is highly recommended to perform a challenge test. This test verifies that the chosen preservative system is effective in preventing microbial growth in your specific formulation under realistic conditions.

Please measure the pH of your scrub and provide the value so we can recommend the most suitable preservative from our range.
