Pros and Cons of Preserving Lotion with Sodium Benzoate and Sodium Dehydroacetate?
I am formulating an O/W body lotion with a target pH of 5.4 and shelf life of 18 months. I am considering using Sodium Benzoate and Sodium Dehydroacetate (INCI: Aqua, Sodium Benzoate, Sodium Dehydroacetate; Brand Name ISCA’s Aquaguard 9093) as the preservation system.
What are the pros and cons of using Sodium Benzoate and Sodium Dehydroacetate as the preservation system for this type of body lotion? Are there any other preservatives that could be used in addition to Aquaguard 9093 to fortify and improve the action of its weaker antibacterial and anti-mold characteristics?
Any thoughts, comments and suggestions would be greatly appreciated. Thanks.
