    Hi folks, 

    Looking at a novel product “Lume deodorant” that promises to: “completely halt the odor-causing reactions on external skin. … Lume blocks the ability for bacteria to consume fluids like sweat, semen, urine, and blood that lead to odor… “
    Which ingredient you think is the one that delivers on the promise? I do not see anything special besides Mandelic Acid. Would love your opinion.

    Panthenol

    Caprylic/Capric Triglyceride

    Less than 1% Ingredients

    Allantoin

    Xanthan Gum

    Sclerotium Gum

    Tocopherol

    Lavender essential oil (scented version only)

    Clary Sage essential oil (scented version only)

    Polysorbate 60

    None.

    For my AT/deo cream I use triethyl citrate (Dermofeel TEC eco) as deodorizing active (and aluminium chlorohydrate as antiperspirant.) (Although I expect most, if not all, from the AlClOH).


    ‘Completely halt the odor-causing reactions on external skin. … ‘ 
    What a bold claim btw!

    N.B. I use these ingredients in an AT/deo cream for the armpits only.
    I don’t see the use for or value of deodorants for ‘private parts’, like this Lume product advertises. Deodorizing odours from blood, urine or semen? These people need a shower, not a deodorant!

    @Doreen the product is intended for dry to very dry regions where there is very little or no water. And absolutely  NO USERS??? and what a topic to end the season with. 
    Happy holidays

    I also don’t see a Deodorant active that jumps out at me. I have seen some try and attach this benefit to the Clary Sage.
    As far as “completely halt the odor-causing reactions on external skin. … Lume blocks the ability for bacteria to consume fluids like sweat, semen, urine, and blood that lead to odor… ” goes, this sounds to me as if a Marketer dressed up the action where the bacteria are blocked from causing malodor. They really put some effort into that statement!

    There isn’t anything obvious that would function as a deodorant active per se, except perhaps the Clary Sage. 

    If the LOI is correct, most of the work would be done by the high level of Mandelic Acid creating a low pH surface on the skin where this is applied plus some antibacterial effect from the EHG/Phenoxyethanol & Clary Sage.

    haha :)) right, a shower is better. Thanks for comments, folks. Users seem to be very pleased with the product but then again, could be false reviews.

    Ethylhexylglycerin is a deodorant active. It is sold by Schulke as Sensivia SC50.

    Sensiva SC50 would be used at a higher level. I would wager that they were declaring the preservative, such as Euxyl PE9010.

    My best guess is that the product does not deliver on the expected promise. But if you read the claim, it’s pretty wide open for interpretation. 

    Lume blocks the ability for bacteria to consume fluids…”

    It could do this in any number of ways.
    -killing the bacteria
    -binding with bacteria receptors
    -physically separating bacteria from the food source

    or since there is no way to measure what it means to “block the ability” it could have no effect at all. Some people will just like how it feels on the skin or how it smells and believe that it’s working. 

    or it is indeed a fake review. I think a large percentage of online reviews are fake.
