  • Vaginal safe preservative and ingredients

    Posted by MaidenOrangeBlossom on March 4, 2023 at 12:43 am

    I’d like to formulate a personal lube for older women or even women with cancer managing vaginal dryness. What is a safe eco cert or food and vaginal safe preservative? Which ingredients are safe to apply to the vulva/vagina for dryness from menopause/radiation etc? It should also be food and condom safe as well. Would GDL work along side Leucidal to maintain the shelf life?

    Appreciate your professionalism and concern for safety. In that regard, please drop the Ecocert charade and forget the GDL/Leucidal - in any application.

    Suggest . parabens and organic acid(s).

      I agree- traditional would be safer, cheaper and better but it seems to be an trend right now. Its unfortunate as a lot of times these are exponentially more expensive and still fail challenge testing. ???? “but the supplier’s marketing propaganda said this leaf would give 3 yr shelf life”

    I’ve developed a few “clean” vaginal lubricants for a brand. The preservative system of choice for these brands tends to be potassium sorbate/sodium benzoate. I have a preference for more robust systems, but this combo seems to be the standard for “clean”. Just make sure to pH the product correctly as these are pH sensitive.

    Before you go too far down this path … Are you aware that what you are describing is regulated at an FDA 510K Medical Device. The testing to get a product like this to market runs around $200,000.

    But, yes, the salts of organic acids are generally preferred in these products. You might also consider coupling those with Phenethyl Alcohol

      FDA is only valid for USA though.

        Fair comment; though in many countries such products are also considered a medical device. However, sometimes it does come down to the wording on the pack.

        Treating vaginal dryness would be a medical claim and thus a medical device in many countries.
