No control over making (quality?) of your base soap? What is source of base?
With above, not only does “Premium” seems unsupportable - but how do you ensure the safety of your product? -
Geogard 221 is not natural and as you found is not that great of a preservative system in any context. The best preservative systems is prob. a formaldehyde releaser, parabens and EDTA.
Natural in the literal sense - there is nothing to recommend.
“Natural” in the COSMOS/Ecocert marketing sense - you formula dependent. -
Methyl - 0.2%.
In theory, Gram negatives are the risk for shampoos so DMDM Hydantoin alone with EDTA would seem to be enough. In practice, combination with another increases protection vs. Gram negative adaptation and is a much better system. -
Your formulating with another company’s product, apparently a drug product.
Don’t think you listed those ingredients.
Are you planning to sell this? -
No - that’s way too much
-
Dump it. Please use GMP
-
With benzoate
-
Yes - colonies in monsavon soap - think Kurtia
-
That is upper limit — start with 2000-2500 ppm active
-
They prefer anhydrous but suggest at least 60%, offer no data - then formulas with 35% (shampoo) no data and and weasel words. It’s an undescribed hydrosol that prob has the usual components pinenes terpineols etc. at whatever levels.
look like niche marketing without much substance -
Pseudomonas typically in consumer tap water and consumers lack of care will risk contamination. Decide where your ethics take you.
-
Milk in bar soap will increase micro contamination risk
-
4 months? If selling - how will you ensure consumers will not use any products older than 4 months?
Where did you get that info re cardamom ? -
Some toothpaste products do not include preservatives. Combination of pH, water activity, pyrophosphates, flavor (esp. peppermint) may be effective. Risk is largely manufacturing as tube packaging substantially reduces risk of consumer contamination.
Sodium lactate is not a preservative.
Preservation is your responsibility. -
How well controlled/specified are your relevant ingredients?
-
Agree Mark - and pH should be a specification to serve efficacy that can be achieved more more cheaply.
@Cafe33 - assume your not claiming that combination as “natural.”
-
Formaldehyde releasers 2000-3000 ppm have given 100-300 ppm free formaldehyde. Folks don’t use formaldehyde now, the releasers are much better in maintaining an effective level..
-
Geogard Ultra + Sodium Citrate + Phenoxyethanol + EDTA, pH 4.8-5.2
What is the product and what are in-product levels of preservative components??
Suggest you drop Geogard and use Na benzoate. Geogard ultra is an overpriced combination that you don’t need - With EDTA gluconolactone is a waste.
Na citrate also serves no purpose.
In any case, please use ISO 11930 (criteria) rather than USP 51.

None of them are that good, and that some org takes it upon itself to redefine “natural” does not change the fact that these are synthetic. “Approved” merely gives license to mislead.
-
I’ll send text if you can’t get in
-
You can register - think the journal free
-
Some are allegedly natural - some are clearly not incl. GSE, Silverion, Geogards 221 and ultra. Further GSE is a fraud and Leucidal has similarly been reported to include synthetic disinfectant actives.
The future of their use - many will to continue happily to buy into and repeat the credentialed “natural” lie for synthetic systems. Those pursuing systems arguable natural (without the disingenuous quotes) will continue to risk consumers safety with weak systems of inconsistent chemical composition.The future of cosmetic preservatives?

The larger question is the microbiological safety of cosmetics -
My bet - if FDA asked for safety data, they’d have nothing much to share.
-
They’re required by regulation to display some information at “point of sale” - this includes ingredient labeling. It’s routinely ignored
-
Good point - guess they’re trying to fly under the radar with “conditioning” claim. They do mention hair growth with ingredient
Trifluoromethyl Dechloro Ethylprostenolamide
Trifluoromethyl dechloro ethylprostenolamide is a prostaglandin, or lipid compound, that is associated with increased hair growth.
