Question
I am making a toner formulation that contains Rose Water and Witch Hazel.
Is it necessary to add a preservative? Is Mild Preserved Eco at 1% suitable for this formula?
Answer
Based on your toner formula, which contains a high percentage of water-based ingredients like Rose Water and Witch Hazel, adding a preservative is necessary for long-term storage to prevent microbial growth. The staff's recommendation of Mild Preserved Eco at 1% is a suitable broad-spectrum preservative for this type of formulation.
