Preserving Tamarind Juice for Hair Serum
Question
I want to use tamarind juice in a hair serum formulation. Can I add preservatives directly to unsterilized tamarind juice? If not, what is the proper method? Also, can I use NaturePreserve™ at 1.25-2.0% and Thyme Care™ together?
Answer
Based on the information provided, adding preservatives directly to unsterilized tamarind juice for your hair serum is not possible or effective. Tamarind juice has a very high microbial load, which requires a more rigorous method to eliminate microorganisms.
You would need to perform an effective sterilization process on the tamarind juice first. Examples of effective sterilization methods include using very high heat (like autoclaving/sterilizing) or gamma radiation. These methods ensure that microorganisms are completely killed.
Once the tamarind juice has been completely sterilized, then using NaturePreserve™ at a concentration of 1.25-2.0% would be sufficient for microbial control in your formulation.
Regarding your question about using both NaturePreserve™ and Thyme Care™, the information suggests that NaturePreserve™ is suitable after sterilization. Thyme Care™ was not mentioned as a suitable option in this specific context by the staff.
