Questions on Preservative Compatibility, Safety, and FDA Documentation
Question
I have a few questions regarding preservatives and formulation:
- Can NaturePreserve be used with Silky Serum Base or Soy Lecithin? What is the recommended usage percentage (around 1%)?
- What is the difference in usage between NaturePreserve and Mild Preserve Economic (Ethylhexylglycerin/Caprylyl Glycol)? Which one is considered safer or less irritating?
- When applying for FDA registration, does the company provide ingredient breakdown documents?
Answer
Regarding the compatibility of Macadamia extract with Silky Serum Base: The staff does not have information on this specific extract and cannot confirm compatibility.
Regarding the use of NaturePreserve with Silky Serum Base: Yes, NaturePreserve can be used with Silky Serum Base, provided the formula's pH is within the range of 3-6.
Regarding the difference in safety between NaturePreserve and Mild Preserve Economic (Ethylhexylglycerin/Caprylyl Glycol): Both preservatives are FDA-approved for cosmetic use within specified limits and are generally considered safe for health. Allergy risk is individual for any ingredient. However, Mild Preserve Eco was specifically developed to be less irritating and is likely to cause less irritation compared to other preservatives, including NaturePreserve.
Regarding documentation for FDA registration: You can request the necessary ingredient breakdown documents from customer service at care@myskinrecipes.com.
