Help me make sense of this: effective and compatible over a pH range of 3 – 8.
As you know…I help out on beginner forums. Where preservative selection is done by polling other beginners. So here is the INCI of one they love to flock to:
Benzyl Alcohol (and) Salicylic Acid (and) Glycerin (and) Sorbic Acid
So… I see an alcohol…and two acids. All is somewhat good to this point. But …. What about that title… Mfg says this magic elixer works at a pH range up to 8! Now memba…most of these folks that have flocked to this, have never heard of a chelate….and they have piled more bug food into the formula than a F-bomb plus parabens could handle. That … and the pH…is just gonna be native. Heck…what good would adding lactic acid do? 😂
So can one of you chemistry whiz’s tell me how those last two ingredients are gonna help when the pH gets much above 6?
I suspect the ‘eager to sell product’ mfg…is of the attitude…that JUST the Benzyl alcohol will carry the load in the 6-8 pH window? Am I wrong? Will these neutralized acids…have some magic residual activity I am just to dull to understand?
The mommies and I…look forward to your answer.
