  • EPC-K1 for deodorant

    Posted by Bluebird on June 5, 2023 at 7:53 am

    Has anyone tested that and seen good effect?

    I read a paper saying that EPC-K1 can have anti-odor generating efficacy.

    However, the cost is quite high-more or less $4000 per kg!

    Amount per product doesn’t have to be high, though, so cost is manageable.

    But it would be more reassuring to buy this after I hear some good accounts from people who’ve tried.

    DO you mean the tocopherol diphosphate ester used in pharma? Of course it is expensive! Just because its pharma, right? Wouldn’t a combination of ethylhexylglycerin and zinc ricinoleate plus a little PCMX handle it just as well for a lot less coin? Just sayin’

      They would have different effects that do matter.

      But EPC-K1 is also used for cosmetics already, so not just pharma.

      I believe it’s just expensive now because it’s uncommon.

      But why ethylhexylglycerin there?

        EHG is a well known member of an elite set of constituents for deo. It works synergistically with other ingredients to manage the bugs. Deo is ALL ABOUT….bug management. Human body does not produce odor!

    I guess we are wondering….there are absolutely bullet proof ways to make amazing deo….why would you spend big $$$ for suspect ingredients….when the good ones are cheap….and right in front of you?

      EPC-K1 manages odor even when there are bacteria.

      Other ingredients try to kill bacteria.

      But bacteria make a comeback-for some people, easily.

      It is a matter of always try to kill vs having an additional weapon as an additional layer.

      Blatant killing without additional measure often does not work well in fighting microbes.

      However, I’d like to hear what are such awesome deo recipes you mention.

      Do you know ingredients that would lead to at least 48h odor protection?

      Please share, I have a lot to learn.

    There are a couple of approaches in deo….one is….don’t worry too much about the bugs…just catch the odor they produce.

    I am not real keen on that approach…to me…the cows are already out of the barn…and you’re trying to close the door.

    The other approach is… minimize bug levels to the point they don’t create enough odor, to offend the user, or those in proximity. I like this approach much better…but this is just personal opinion. So…the solution for this system involves lower bug population…and keeping it there. As you know…a low pH product applied to skin…the skin will in very short order…return the pH to the pH it wants…..so an initial application…might give 30-60 min of the desired effect of pH. If only there was an ingredient…that could extend this lower pH…for a longer amount of time… (you know…kinda like a buffer system). ????????

    I think the other aspect is finding ingredients…that have a little staying power…..if you want extended protection. If you look at products of yester-year….there was something called Triclosan, that did a bang up job as a deo active. Well, that is of course yester-year….so if only there was something more natural….that did what Triclosan did…. ????????

    If you think about it long enough….you’ll figure it out. 🙂
