    got it - do use ISO challenge method and criteria.

    Prob doesn’t hurt to add sorbate - the stuff isn’t that stable through time consistent with consumer use.

    Citrate is not that good a chelator in this context (but prob as poor a prevative as phytoBS). Maybe GLDA?

    “seem to be present” - is this in challenge testing or just de facto content testing?

    Good grief - drop the silly PhytoBS. No one knows what’s in the stuff - other than the claim of “salicylates”. Assume you are chasing “clean” BS, control your pH to <5, drop the sorbate, do add benzyl and perhaps a long chain glycol. You need a chelator like EDTA. Find your own green one but not gluconolactone.

    Your problem is Gram negative bacteria.

    Could not open photo.

    Might be microbial contamination - a fairly common bacterial contaminant Serratia marcescens produces a red pigment and your preservative is absolute BS.

    She may have heard it from a source she trusted. Appears a lot of ophthamologists are ignorant re. preservatives too - https://www.contactlensjournal.com/article/S1367-0484(13)00025-8/fulltext

    Holy crap - what an idiot! Of course you don’t want ingredients that fire up the eye - the consumer will very likely/hopefully toss it before they can contaminate the stuff. They may never know it’s full of bugs - until they get an infection.

    The eye is uniquely prone to infection from cosmetics with blindness as a result. https://www.sciencedirect.com/science/article/abs/pii/0002939477903348 - for this one, point of entry was thought to be inadvertant contact of mascara brush to cornea with to minor scratches.

    Right - you know that clown has no idea the safety and mildness around the eye of her weak naturals.

    FDA is esp. concerned with contamination of eye area products. In fact, cosmetics were included in the original FD&C act of 1936 because of eye infection. Ironic toi this discussion - irritation may have been involved. The agency has eye area products as a big worry.

    Please determine if distilled or deionized water shows the same problem.

    It looks like the CM needs help to meet your specs. Either you/your partner invest expertise or find a capable CM. I’d not waste much time in addressing the “or”.

    September 11, 2023 at 8:55 am in reply to: Raspberry ketone as a multifunctional preservative

    Another miracle “natural” preservative - broad spectrum, wide pH range, heat stable, even “multifunctional” and vegan and some wonderful data. That never happens. In real life, there are no such miracles - efficacy as it may be is due to chemical consitituent(s) alone or in combination at effecitive level(s).

    As with any complex mixture, composition can vary from batch to batch. Presuming the miracle and as preservation is a critical function, supplier (Ashland) needs to provide CoA that confirms analytically the active principles are at specified levels. Failing that you should do efficacy testing for each product with each batch.

      p-Hydroxybenzyl acetone 4-p-Hydroxyphenyl)-2-butanone - the active. It is produced synthetically and naturally of course from raspberries. Also synthesized by bacteria and fungi from 5 ppm with one report of max level~100 ppm. So if natural extract - how much raspberry ketone is in raspberry ketone.

    Raw material spec is discretionary but to your concern, you don’t want the raw to put your finsihed product out of spec. If the spec on the material is 10/g - 200 puts it out of spec making it and any relevant product adulterated. 10/g for is pretty low for this kind of stuff.

    Can you describe the raw material - a fluid extract? powder? and the finshed product shampoo? cream? pH? The “at least 200” here might mean the stuff is indeed moldy/adulterated - recall mold growing as colonies will not disperse well. As Mark said, citric acid is not going to help.

    Mark’s post was spot on for dates of compliance. Agree, timing looks tough but the Agency will likely take the position that safety has always been a requirement and this merely asks that it be documented. To your concern for anhydrous, generate a justifying risk assessment

    Establish your “responsible person”.

    Begin your own adverse reporting system.

    Work in good faith. Comply to the letter of the law - no more no less. Ask questions here.

    Be aware - this is a new group at FDA. We don’t know if it will include the CFSAN folks who had cosmetics before but the CFSAN guys I know do not expect to move . In any case, the new bunch is scrambling to build an org. and meet their own target dates.

    Good point - as MoCRA will make folks more accountable for safety up front.

    I know nothing of “assignment bro” - appears to claim service as academic writing resoruce rather than safety assessment.

    September 12, 2023 at 5:56 am in reply to: Honest reviews on the institute of personal care science

    Good points. I’m developing an online course - cosmetic manufacturing hygiene focused on microbiology - for the Spring semester at a university. Of the many lectures, I’ve prepared only a few. All the many others are by some of the most experienced industry folks I believe in the world. Re. these experts, I know content is right and delivery is my primary worry. Great expertise is not always accompanied by great communication skills and these folks are not educators. In fact, I’ve something of a bias against “professors” . Most publications by academics addressing cosmetic microbiology are poor to total crap. For my lecturerers, this is not their day job so one can only ask limited revisions by these busy, proud folks.

    I’ll see how the course is received, test and poll students. If it continues, i hope student comments re. indovudal lectires can improve the effort.

    True - consumers do not accept a product as premium (in performance) unless priced as premium.

    You can’t clean up an OOS raw material.

    Alot of naturals are effectively preserved by Aw with glycols - fungi being the remaining, moderate risk. Adding more preservative to an OOS material does not change its adulterated status and in this case prob won’t work.

    Shampoos and conditioners very rarely have problems with fungi, but this is the supplier’s problem to fix, not yours to accept/attempt to control the risk as proxy for your customer - who owns the risk you take. Suppliers CDA specs - total aerobic count @ 100/g and fungi and “levaduros” (yeast) @ 10. Your 200 and greater shows these guys are not in control. Start up with this and you’ll be stuck with whatever they send - accept it or shut down production. They’ll say no one else complains - so get 3rd party lab data to support your complaint.

    Decide what you’ll share with your customer.

    To graillotion’s exce;lent post, I’ll add that metely adding prreservatives means little AND the comment that the problem was the consumers’ is absurd - the purpose of preservation is to protect the consumer during use.

    The product should be recalled. What brand is this?

    Nope there is a range - suave is positoned more economically and there are store brands. So why do folks buy Pantene?

    Thanks Mark.

    The anhydrous tests I’ve seen are tests for the sake of a test. They strain to offer any sense of reality. Failure may mean little to nothing re. actual risk but more apt to fail than not - sure would screw up ones safety assessment. Jumping in with a product already on the market could be a disaster - failure a time bomb waiting for some regulator or law suit to discover.

    Mark can you share the FDA source comments mentioned?

    Disagree with running some test on whatever “anhydrous” product - unless you know what the results should be, have reason to beleive you’ll pass and plan to do it ongoing. USP 51 is weak enough in validation - many anhydrous tests are pretty flakey.

    There are no specifics at this time tho’ HRIPT is reasonable - but may be be minimal. If micro is required, it’ll probably be satisfied with a risk assessment that includes challenge as appropriate.
