Robust Preservative Combos?
Good morning everyone,
I hope you are all safe and doing well. I want to express my gratitude to this forum and the professionals that are so gracious in sharing their knowledge. It truly means a lot to people like me who are still learning. I humbly ask for opinions on preservative combinations. I’ve been observing preservatives used in bigger brands’ products as I’d like a more robust preservative system for the products that I create for myself and my family. With proper GMP (I DIY in my husband’s lab), low to medium risk packaging, chelation, and less than 5% botanical extracts in mind, I would love to get you guys’ opinion on the following preservative systems:
1. Euxyl 703 (Phenoxyethanol (and) Benzoic Acid (and) Dehydroacetic Acid) (I apologize as I’ve forgotten which company & product I saw this in combo in, which led me to buy this.)
2. Euxyl PE 9010 (Phenoxyethanol (and) Ethylhexylglycerin) + Sodium Benzoate (I saw this combo in J&J’s baby shampoo)
Question regarding #2: What would be an appropriate percentage of sodium benzoate to use? Would I use COSING’s max limits?
Despite educating my family on the safety of parabens and f-donors, they still ask for me to not use them. I tried :’-( As always, thank you for you time, thoughts, and inputs.
