to the chemistry, I found the primary formula variable controlling free formaldehyde was perfume.
-
Sadly - I think the EU limit is 10 ppm so free formaldehyde per se is irrelevant- don’t use FA releasers in that regulatory climate.
FA releasers are also banned in Washington state. https://www.bdlaw.com/publications/washingtons-department-of-ecology-plans-to-ban-formaldehyde-releasers-from-cosmetics/
Ignorance is the only excuse.
-
meant the cap and pent glycols
-
What is formula, package and product? This would not be esp food in a shampoo.
Generally, Na benzoate is ok - glycols are too low and needs a chelator.
-
Please speak in chemical names - not supplier terminology. Phenoxy/EHG with Benzoate and EDTA is reasonable. Why not use CMIT?
-
Can you name the product?
-
You do need some preservation
-
The crappy odor is not something to mask - it indicates a stability issue you need to address
-
Unfortunately MoCRA did not include the state preemption that brought support of the major companies and PCPC in the Feinstein-Collins senate bill.
Beware politicians, their posturing ignorance knows no bounds.
-
Sure looks that way and no, major brands will not attempt to break our those 2 states.
FA releasers have lost market share for some time so prob. not a major impact.
-
Incremental change will not buy much. Why can’t you use CMIT and EDTA?
-
pH?
-
What “antibac”? and why?
-
Ok - and please, EDTA
-
Think a formaldehyde releasers would be a better choice.
-
CMI.
-
That’s a tough question. It is rinse off but an intimate area. Think I’d not use it in this context.
-
benzyl alcohol and benzoate work in formula?
-
Phenoxy with a questionable ester. Can you use EDTA? The gluconolactone (breaks down to gluconic acid) is not much.
Need something for fungi - what’s pH?
-
What is your policy - FA releasers? parabens? “natural”?
-
Would you please add a preservative
-
Thanks, I see. Suppose parabens and IT’s are off the list too. oh well.
For leave ons (with lament for FA’s, i knew them well)
9010 with EDTA and benzyl, benzoate or DHA. Control pH. They can add sorbic with benzoic - some think it “synergistic” but I wonder at stability. If they need more efficacy, add glycols (cap or pent or both) at 1% or greater. Dave Steinberg insists antioxidant with benzyl but I don’t think that is a problem.
For surfactants and hair conditioners (with a lament for CMIT, another friend)
9010 with EDTA- and benzyl (for conditioner) and benzoate( for surfactant ) control the pH.
-
Germall + but still a FA releaser. 9010 not much for fungi and weak vs Gram +
-
Maybe that the stuff is another crap, patented preservative combination, bait for those eager to use a fake natural claim?
-
Please Phil. Phenoxy and cap glycol are not natural , commercial sorbate is synthetic and formula 95%+ synthetic.
To your question - the levels you had should have worked and incremental increases are unlikely to make a difference. Please track down why you had apparent contamination - poor water quality, contaminated raw material, failed making hygiene, something.
