Imagine my surprise!! Ricky Mountain product development never got back with info requested.

Hard to see how they “sterilize” and maintain as sterile packaging and raw materials and how thyey consider Aw in context of an emulsion.
Asked for validation through consumer use - they forward to their product development.
Let’s see.

here’s what they said, it’s BS
Products can be made with zero preservatives (oat lotion) adhering to the following conditions:
Use 100% sterile raw materials
Use 100% sterile packaging materials
Follow strict GMP from start to end, as listed below.
Design the product as very low water-activity
Maintain the pH in the 4-6 range
Use raw materials which act as pseudo-preservatives.
Minimize human (user contamination).

Sure seems risky. i asked for their justification Let’s see what they say.

Can you identify the specific product/brand?
Is there anything unique about the package?

I’d confirm Biotin is responsible, and if so, reduce it to 0.01%

Cetyl ethylhexanoate is an ester.
Work with the definitions

To Microformulation’s point, city water typically includes Pseudomonas aeruginosa etc. at some level, typiucally in a biuofilm context. IF you use it, you should heat it 1st -prefer 80C but at least to minimal Pasteurizing levels - ~60C.

You should check Philippine regs.
60-95% is the typical range - but please be aware the aloe and guava may screw up your efficacy.
-
Is this for personal use or to be marketed - and in what country?
-
0.7 prevents growth, does not kill. For emulsions Aw may not matter.

PLEASE - read this stuff carefully before accepting it’s BS.
The guava article is a classic example of garbage science published in a 3rd rate journal. Their protocol couldn’t tell the diff between Pov-Iodine and saline or likely anything, much less show something about guava extract. Everthing was the statistically the same so they concluded an “implied”a benefit for guava.
The other links are to verbage.

As a “disinfectant” - antiseptic, ethanol is an active. How/to what action/efficacy are guava extract, centella extract and aloe vera extract “actives”?

If you’re in US - wave MoCRA at them, might be a like crucifix to a vampire.
