Mild Preserved Eco™ and Face Mist Formulation

Regarding your questions about Mild Preserved Eco™ and its use in a face mist formulation:

1. Is Mild Preserved Eco™ a Broad Spectrum Preservative?
   Based on the product description, Mild Preserved Eco™ is not classified as a preservative according to FDA regulations and is described as "Preservative-Free". It functions to control microbial growth but is not explicitly stated to be a broad-spectrum preservative like Mild Preserved™ COS, which is specifically described as broad spectrum.

2. Can it be used in a water-based Face Mist?
   Yes, Mild Preserved Eco™ can be used in water-based formulas like a face mist. The description indicates it can dissolve in water, although it requires blending.

3. Is an additional preservative needed if using Rose Water, Lavender Water, and Chamomile Water at 60% combined?
   According to the descriptions of Rose Water, Lavender Water, and Chamomile Water, if these floral waters are used as the main ingredient (over 60% of the formulation), there is no need to add additional preservatives because the manufacturer has already added a preservative (Phenoxyethanol) to these ingredients during their production. Therefore, if your formula contains 60% or more of these pre-preserved floral waters combined, you would typically not need to add another preservative like Mild Preserved Eco™ or Mild Preserved™ COS.
