Too Much Preservative?
Hi everyone, I am tasked with a hair and scalp mist and would like your opinion on the amount of preservative used. We are using Phenoxyethanol and Ethylhexylglycerin at .8%, Sodium Benzoate at .3% and Potassium Sorbate at .2%. We are also using a chelator at .1%. Is this overkill? pH will be approximately 5.
Distilled Water 87.65
Aloe Water
Hydroxypropyl Bis-Hydroxyethyldimonium Chloride
Glycerine
Polyquaternium 81
DL Panthenol
Phenoxyethanol and Ethylhexylglycerin 0.8
Sorbitan Oleate Decylglucoside Crosspolymer
Allantoin
Sodium Benzoate 0.3
Potassium Sorbate 0.2
Tetrasodium Glutamate Diacetate 0.1
Lavender Essential Oil
Tea Tree Essential Oil

These are on the high side BUT, within the boundaries of safety (per established ceilings and HRIPT if you can access), there is no “too much preservative”. Folks here work under the technical cover of USP 51-type testing that merely tells that a preservative effect is there - not that it’s enough. Be assured that every cosmetic recalled passed that test and prob with complete kill.
Some pharma micro folks titrate their systems to just pass USP 51 effectively assuming a safety role. To my perspective this is absolute BS. I hope none here follow this stupid practice.
