    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).

    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%

    Stability should be conducted in your product package.

    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.

    0.7 prevents growth, does not kill. For emulsions Aw may not matter.

    I have some insight re. this - the active is not the only “tricky” element.

    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”?

    Yup - I remember those days - and everyone in the room nodding in unison to meaningless jargon.

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

    These are effectively the same test in execution with 51 crtieria being less stringent. As established passing through stability, it would be seen as justifying marketing.
