    I‘ll add, presuming a short shelf life for any category of product is irresponsible. Hydrosols are not preservatives.

    If you’re in US, Saligard is neither legal nor esp. good for your application. Again in the US - regulations limit how much alcohol you can use.

    To the “shelf life” - is the supplier stating their product is not chemically stable? Think they’re pulling that stuff out of their butt.

    Wrong to add preservatives? This is an aerosol product that folks will inhale. It’s very wrong to risk their health with a poorly preserved product.

    Anhydrous oil, why do you need an antimicrobial preservative?

    3.5% IPA is not a preservative

  • Hydroxamates are ok versus fungi not Gram negatives

    Trust folks who call it “natural”? Benzyl has some efficacy versus fungi

    Sorbic acid is not that great a preservative for stability considerations.

  • If you want to sell in US. Assume this is a pump spray.

    Germall + is not at safety issue, tho’ there are some concerns for aerosolized IPBC. But it’s not legal in household products. You need to use chemicals registered with EPA as pesticides for use as preservative. Pretty sure phenoxy and certain cap glycol are not registered (don’t think much of cap glycol in any use). Consider a registered DMDM Hydantoin- e.g. Dantogard with some ethanol and maybe some Sodium Benzoate is your pH allows. Emerald Kamala now Lanxess sells a registered version. Low levels of ethanol even down to 5% can help, but you need ~20% to assure preservation.

    You must ensure every chemical in your product is on the “TSCA inventory”. https://www.epa.gov/tsca-inventory.

    VOC reg’s are a pain and vary among the states. Use California’s – none are more demanding. . https://ww2.arb.ca.gov/sites/default/files/2022-11/Consumer%20Products%20Reg%20Article%202_11-30-22.pdf

    Reading the reg’s is complicated and haven’t dealt with those guys in years but look at the reg’s – you need to decide what you are. Air freshener pumps are 18% VOC but fabric refresher is down to 5%. There is no “Linen spray” category per se. They regulate VOC content by weight with “VOC” being any carbon containing chemical with few exemptions so your product’s plastic bottle is 100% VOC. BUT I recall exempt those with vapor pressure < 0.1 mm Hg at 20C.

    They should be with right pH. Added as salts. I prefer just benzoate - sorbic acid stability can be troublesome.

    Neither would be legal in US. Add alcohol think the limit is 5%- not enough on its own but it helps. Preserve with Dantogard +- DMDM hydantoin + IPBC - legal in this application. Some add phenoxy with the “solvent” excuse but it’s not thre best if you have freedom to use others.

    If no water - as in none added and none in ingredients - doubt you need a preservative. You still need to test for content - numbers of microbes.

    Organic acid(s) prob ok for y/m. I’d also add a chelator?

    Please challenge test.

    Can’t offer comment to that without context - product, pH, other preservatives.

    The thought for a shampoo. Do not use Kathon in leave on product like hair wax. What is formula - esp how much water

    No water? Nothing in ingredients? Does it take up water in a humid bathroom?

    Seems reasonable - need to confirm with appropriate testing.

    No, ketchito is right. Appreciate that parabens are being considered but will not be enough in this context. Suggest addition of formaldehyde releaser like Germall or Glydant or an isothiazolinone like Kathon CG.

    Would not expect enough

  • Phenoxy+EHG should be ok in that range v Gram negatives - do not trust supplier BS

    The latter is much better

  • You can see how discouraging state regulatory activism is to small businesses. Regulations like these favor big guys who have staff to understand and negotiate and money to comply. They stress small guys who are surprised and haven’t the money and expertise to reformulate without screwing up their product. Big guys can pick off those with good brand names.

    Phenoxy/cap glycol may work but is not a legal preservative system. They might have contrived a BS story as cover and hope EPA never gets around to looking at their product - phenoxy is a perfume carrier or solvent and cap glycol is ???

    Perry’s right. Big guys acquire little guys for brand names and less so products. “Due diligence” is financial and rarely gets down to the folks who know products so most of these generate a bunch of “oh shits!” - micro, safety, regulatory, manufacturing ,personnel problems the resolution of which erodes excitement.

    My bet - Body Shop was one of the 1st to use very successfully social and enviro activism to communicate brand. They used little to no conventional advertising so their initial success did not stand up to other brands chasing the same positioning <b style=”background-color: var(-bb-content-background-color); font-family: inherit; font-size: inherit; color: var(-bb-body-text-color);”>with conventional advertising. Acquisitions by big companies can be strategic and can be on a whim of management. Bet Body Shop was more of the former - we can rescue this fading brand for a position in a sector we don’t now occupy. Immediate result is always loss of true believers - activist folks who see big companies as the devil and here Roddick as selling out. Bet there were oh shits - including Roddick. Whatever Unilever did - this was still a small brand and management changes of the next years saw it as a distraction that needed to go. years
