    Mike - re.” Importantly, we must make a distinction between synthetic and essential oil fragrances. Safety assessments have not been conducted for many of the synthetic fragrances.”

    I dispute this statement. Extensive safety assessment IS conducted by major manufacturers for their perfumes and perfume ingredients - synthetic or otherwise. These data are not made public as they represent substantial investment by perfume suppliers. I’ll offer that natural ingredients including essential oils in general have much less (some no) analytical and safety data support - both as expected and as supplied.

    Further, we should avoid casual, unjustified scare mongering.. re. “Avoid any product that uses the words fragrance, parfum, phthalate, DEP, DBP, or DEHP in its ingredient list.”

    Consider phthalates. Citing its own findings and conclusions of CIR, CDC and NIEHS, FDA comments “… the FDA does not have evidence that phthalates as used in cosmetics pose a safety risk.”

    Good idea - but do not “blend”. Formulate as individual ingredients and, if pH allows, use Na benzoate rather than sorbate. Doubt you really need the tocopherol.

    Adding tap water will add Pseudomonas aeruginosa - a typical water bug and one of the worst for cosmetic contamination. Using the same bottle with the added water will give it a chance to adapt and grow in your product.

    Consumers in general are, at best, vaguely aware. Pressure comes from retailers and their “priority lists” influenced by industry parasites loke EWG and EDF (e.g. https://www.newbeauty.com/how-sephora-is-doubling-down-on-their-chemical-policy/). And there are is occasional moronic legislaion (e.g. https://ecology.wa.gov/waste-toxics/reducing-toxic-chemicals/washingtons-toxics-in-products-laws/toxic-free-cosmetics-act).

    Alternatives - “natural” (that very rarely are), clean beauty, preservative-free etc. preservation is sold on ignorance and hype as are the broader product claims of biodegrable, natural, green, environmentally friendly, sustainable, etc. The number of such product claims is typically inversely proportional to micro and chemical safety. But that IS the basis of our cosmetic business, ignorance and hype - add hope and self delusion.

    Mike you are not a toxicologist (nor am I) and it is not agreeing to disagree - it is risk assessment vs risk elimination (aka scare mongering). As with parabens and some of chemical targets of endocrine disrupting scare mongering, there are data of some effect (tho parabens data are often crap). Science addresses those data by estimating the risk in use - and that is the practice of toxicologists at FDA, CIR SCCP, IFRA, P&G, Unilever etc. Presence of data/potential risk/publishes articles means nothing practical until placed into a use context.

    The only totally safe material/chemical is the one that hasn’t been tested. Risk assessment considers exposure, effect, NOEL, product context, etc. by standardized and validated protocols and specified safety factors.

  • Cynical posturing from a criminally-incompetent Indian company. “Abundance of caution” with a body count and FDA Enforcement Report noting “Non-Sterility: FDA analysis found unopened products to have bacterial contamination.” and includes recall from the same folks of eye ointment for the same problem. Marketers were EzriCare and Delsam.

    Dave’s right- tough to see a scenario by which a consumer contaminates eye drops with aeruginosa but obviously a manufacturing risk.

    What is your preservative policy? do you use formaldehyde releasers? parabens? And what is your pH?

    May or may not be important to your problem but that is a useless preservative system

    Nancide (assume Naticide) is a sham. If by “Grapefruit extract” you mean the seed extract, you’ve fallen for more BS.

    Great! You should expect no recovery -even one is a concern as you hopefully will be selling the product for years exposing lots of folks. If you find bugs, check product for chemical and physical adulteration. Some folks like to combine products or dilute. Chemical adulteration unless frequent, is not something preservative risk assessment needs to address. Dilution is common for shampoos and less so hand soaps. For that, establish the level whose risk you accept. We used 50% as it was common globally and about the limit of what consumers would see as functional.

    Sure Mike, and risk is driven by application and culture. Hand soap product in pump less so than shampoo in a bottle. Culture - e.g. customers intentionally diluting product - some Chinese customers use sachets for months for family washing.

    Mike - I do not know if consumer safety is compromised by your products. Based on our previous exchanges, I understand have no data that preservative function - protecting the consumer in use - is fulfilled with your products. So you too do not know.

    There are no “toughest standards” for functional preservation anywhere but with the major companies who preserve to address in-use risk. And that in general would not be just passing a USP/ISO/EP/BP test.

    Thanks for clarification - I understand the test and a member of the committee responsible for it.

    Do NOT go off happy it passed “unpreserved” - it is preserved but how?. There is a reason and you need to confirm the WHY and confirm that the WHY will be in every product you make through stability. It might be a preservative or impurity in a raw material that the supplier may not maintain, some unique combination of ingredients and process that is not controlled.

    My point is this - one would expect any alkaline true soap product to “Pass” as USP/ISO/ASTM/EP protocol. The bugs are weak sisters - pH alone knocks down and add fatty acids esp. C12 - the product passes..

    But the purpose of preservation is to protect in-use. With good GMP’s and manuf hygiene, one can make poorly preserved products clean. IN[-use - a pump product may protect but in a typical shampoo bottle, you will get water ingress and poorly preserved products fail. We’ve spoken before on this and i understand you have noIin-use data to this risk.

    Let’s see where MoCRA comes out. Mike may indeed be right that preservative testing is required, and I’m sure 3rd parties (good and the EWG types) will offer their services as intermediaries. Haven’t heard that FDA will make that part official.

    Should not use isothiazolinone (here Kathon CG) in a leave-on product.

    Also difficult to get effective dispersion of small quantities (e.g. Kathon) added to finished product.

    Ingredient statement must be provided at point of purchase - with responsibility being on the head of the “guy” named on the package. You’re seeing attemtp at cya from retail folks for their inventory control practices.
