  • Using Magnesium oxide in deodorant

    Posted by ffernandes84 on February 17, 2025 at 7:29 am

    Good morning, everyone!

    I need some help.

    I’ve searched the internet for information about magnesium oxide and its use in natural solid deodorants. I’ve used two deodorants that used oxide and I didn’t get any allergies, but I did with bicarbonate.

    I’m trying to make a deodorant with magnesium oxide, zinc ricinoleate and oils. however, I’ve tried various percentages of the oxide and I really can’t make my armpits feel uncomfortable. I can’t understand how I came to use one that lists magnesium oxide and in the end when I try to make it I can’t find any percentage to use.

    I’ve read that it should be from 8% but I can’t find the correct percentage. I’ve even used less than 1%. when I managed to remove it and use only zinc ricinoleate and triethyl citrate (which is another one that gave me discomfort and then I found a good %) it didn’t work but it didn’t have the lasting effect that I’m looking for 48h+. I can share with you 2 lists of one that I saw on the internet that include oxide with citrate but I can’t find anywhere a basis for using magnesium oxide. I’ve also used it without the fatty alcohols such as cetyl, stearyl and cetearyl alcohol, in the case of wax and butters and finally with the alcohols. and the sensation has diminished well but it’s still there and this time I used 8% with the alcohol. could you share your vision, if you know of anything how I can proceed with this idea? the idea was to make it as basic as possible and that it lasts 48h+ for natural certifications.

    Thank you!

    Most beginners use magnesium hydroxide… maybe if you use that as your query you will get returns.

    Magnesium oxide when combined with water (sweat) has a pH of 10-11. The reason your do not get the pH burns that you got from baking soda is that it is far less soluble in water than the BS is. BS releases that horrible pH on the unspecting skin….all at once. The mags, due to solubility….might for lack of a better term …. be considered ‘timed release’ high pH.

    You seem to be grasping at random concepts you have seen around the net. TEC needs a low pH to function. You are not providing it, so it does nothing of what you think it is supposed to do. It is simply a high-cost ester in your package. Drop it.

      Thank you for replying.

      Yes, I don’t use BS, it was just informative. I’ve been using magnesium oxide and I’ll tell you that I’ve liked the results. as I was looking for something that wasn’t like aluminium, I found the change interesting. I even used 3 different test deodorants to see and compare their use, but they contained more or less the same things. I looked at the ingredients on the label of one of them and saw that it used this list below.

      At first I thought he was using Trietil so that when the magnesium oxide wore off it could have a secondary effect, but I’ve been looking and I’ve also seen it elsewhere, and even something you said about it being used as an emollient. so I thought I’d switch to zinc ricinoleate and use two other vegetable oils that are more geared towards this part of the odor that I’ve seen some studies on. However, the real problem is the amount of magnesium oxide that I’ve seen on the internet. I’ve seen information that they usually use between 5 and 15%. and that it’s not really possible to use it. if you look at the list and get an idea of the amount and secondly from what they say in some documents on the net. that’s why I tried less than 1% to see. because if I use less than 1%, according to the list it can be placed anywhere in the list. however, I lose effectiveness of 48h+. and I can’t find a balance even by increasing the emollients to calm the skin. and this one even uses citrate, and yes it works well for this odor issue, at least it worked well for me.
