As always excellent comments from my colleague graillotion

Safe? Please explain.
Neither is likely to be a good preservative system.
-
Euxyl™ k 712 = Sodium Benzoate (and) Potassium Sorbate (and) Aqua; PE 9010 = Phenoxy + EHG
pH 4-5.
Should be ok. Please confirm with challenge testing as made and in stability.
-
Please drop the commercial names and address the specific chemical preservatives. Decide what actives you want The ones you propose are prob more than you need.
-
Have to ask - what is your pH?

1) It was a buddy at J&J pissed that activists scared his management into 86ing Dowicil (Quat 15) from their classic baby shampoo.

and https://www.cfs.gov.hk/english/whatsnew/whatsnew_fa/files/formaldehyde.pdf
2) Levels vary between products and specific FA releasing preservative. On my exp. with Germall, Glydant, Dowicil, the levels of free formaldehyde were 100-200 ppm and steady. Recall EU regs req’d labeling in >500 ppm to folks were careful to test..
3) Formaldehyde is a carcinogen by inhalation so P&G conducted head space and in-shower studies. Don’t recall levels or if there were any but human safety toxicologist were satisfied with safety factor (orders of magnitude v. NOEL).

The next “innovation” will likely be as fictional as “clean beauty” BS.

I see.
Problematic but prob useless.
Bacteria will certainly grow in water deposited on the surface - esp. with water dissolving sugar from such a high level. If any preservative would work, it would be a highly water soluble preservative like a formaldehyde releaser. But it’s unlikely you’d find protection from any preservative. It would only access that low level at the contact surface - diluting beyond any effective level.
If you have mold growth on the surface, add a parabens.
-
Can you describe how you water exposure makes a preservative necessary?
-
No - it is not.
-
You should have your supplier take the responsibility.
-
I’d not switch preservatives. If you do, you must support 9010 with something for mold and Gram positive bacteria.
-
Heat to reduce and gamma radiation to sterilize. Both will likely screw up your material.
-
For Prop 65 requires labeling for material that cause cancer or reproductive toxicity - “known to the State of California to cause cancer birth defect or other reproductive harm.”
The state lists the chemicals https://oehha.ca.gov/proposition-65/proposition-65-list/
There is a ‘safe harbor concept that allows risk assessment exemption of labeling.
For example, you’ll see warnings for alcoholic beverages, fisingc lures (the paint).
-
Ingredients label of virtually all ingredients but trade secret (FDA approval req’d - only ~one ever) and incidental ingredients
The provisions of this section do not require the declaration of incidental ingredients that are present in a cosmetic at insignificant levels and that have no technical or functional effect in the cosmetic. For the purpose of this paragraph, incidental ingredients are:
In this case - Substances that have no technical or functional effect in the cosmetic but are present by reason of having been incorporated into the cosmetic as an ingredient of another cosmetic ingredient.

Think CIR has it up to 0.1% (you should check.. I’ve used it at much less, down to 100 ppm Issue with anything that low in % and low water solubility is adequate distribution in batch. Some dissolve in glycol
-
methyl parabens 0.2%and propyl 0.1%
with phenoxy - phenonip[
-
pH is sure on the high side, esp. for a cream. You need something for fungi. Maybe sorbate but stability can be an issue. Parabens would be best - if your policy allows. Can you find a combination with IPBC?
-
What does the company claim?
-
P&G can afford equipment and methods that break out effects - not that these will translate to something a consumer would perceive.
-
Think you should start with BS and look for reasons that being veracity
-
Pasteurization - heating to 140F/60C - try it. May not have same same effect as with aqueous stuff.
-
Doubt these will be effective. Bacteria filters work with aq. solutions not oils. Preservatives work poorly on dormant cells and not on spores.
-
Mike - none of that supports your melodramatic, chemophobic “dark side title or discussion and the allergic comment is no more valid for synthetics than for natural (so-called and real). Curious re. the “we discovered”. Is the we - Mike the toxoicologist? Please tell us the data and its analysis.
I understand your marketing effort to differentiate. Please explain “very transparent” in sourcing. Are suppliers names and address on your labels?
-
Claiming sales of a product familiar here to no one here but you is not much of an argument when products of the type Meemcha described are sold at huge volumes globally.
I’d also like to hear the defense of “natural” for this product.
