Hi, Steve Barwick here, for


One of the most frequently asked questions I receive is this:  “Can colloidal silver be mixed with other substances?”


And the answer, of course, in general, is “Yes!”


For example, people use vinegar and colloidal silver together as a very effective fruit and vegetable wash and disinfectant.  To learn how it’s done, read my article A Simple, Effective Colloidal Silver Fruit and Vegetable Wash at this link.
Colloidal silver can also be used with apple cider vinegar as an effective athlete’s foot cure.  For more specifics, see my article Colloidal Silver for Athlete’s Foot and Other Topical Fungal Infections at this link.

Colloidal silver can also be used with a variety of essential oils and other substances to make natural health and beauty care products, including a minty homemade mouthwash, a refreshing homemade aftershave, or even a homemade deodorant spray.

Even More Examples

Experienced colloidal silver users also use colloidal silver in combination with antimicrobial essential oils (i.e., such as Tea Tree oil) for topical use as a “double whammy” against stubborn topical infections such as boils or even MRSA.  Learn more by reading my article, An Unusual Colloidal Silver Remedy for Infected Boils in Inconvenient Places, at this link.


Some people even mix colloidal silver with liquid soap in a pump dispenser to give their favorite hand-soap powerful antimicrobial qualities.  See my short video, Make Your Own Colloidal Silver Gel and Colloidal Silver Soap, at this link.


Finally, people mix colloidal silver with a variety of natural oils or gels, such as coconut oil, argan oil or aloe vera gel, to make all-natural germicidal topical products.  See my article, Germ-Busting Colloidal Silver Gels and Creams at this link, and scroll down to the section on “Making Your Own.”


General Rule-of-Thumb On Mixing
The general rule-of-thumb when mixing colloidal silver with other substances is to make up the combination fresh for each use whenever possible.



Because when colloidal silver is mixed with other substances, over the course of time it can begin to oxidize, or even bond with other constituents of the substance you’ve mixed it with, and lose potency as a result.

Sometimes, there’s not enough potency loss to make a big difference.  But sometimes there is, depending upon the substance being mixed with the colloidal silver and whether or not specific constituents of that substance tend to interfere with the antimicrobial activity of the silver over time.

So, for example, when mixing colloidal silver with vinegar to create a natural, disinfectant fruit and vegetable wash, you should probably consider making up a fresh mixture each time since the acidity in vinegar tends to oxidize silver more quickly than other substances would.

After all, it only takes a few seconds to mix a fresh batch of your colloidal silver and vinegar wash.  And you’ll enjoy maximum potency and effectiveness from the silver by mixing the wash up fresh each time.  If you were to use the same batch you mixed a week earlier, it might not be nearly as potent as mixing a fresh batch.

But when making things like a personal natural deodorant, a natural minty mouthwash or a refreshing natural aftershave by mixing colloidal silver with other substances, most users agree you can go as long as one week without having to mix up a fresh batch.

Some people prefer to make only three days’ worth at a time just to be sure they’re getting maximum antimicrobial potency from the silver.

The bottom line, general speaking, is that the fresher-made the combination is, and the sooner it’s used, the more potency and effectiveness the silver will maintain.

On the other hand, when mixing colloidal silver into liquid soaps and shampoos, the silver seems to maintain its potency very well over long periods of time.  Apparently, certain constituents of soap make for good carriers of silver, rather than acting as neutralizing agents.

That’s why I never fail to add colloidal silver to my favorite shampoo, and to my favorite bathroom countertop liquid soap dispenser!



There is some controversy over the idea that mixing colloidal silver with other substances can negate the effectiveness of the silver over time.

Indeed, in many cases there appears to be very little loss of silver’s potency at all, even over long periods of time.  And this appears to be borne out at least several clinical studies.

For example, one study has shown that when small amounts of silver is used as a disinfectant agent in “multiple dose products” such as cosmetics or pharmaceutical preparations, the silver continues to work over time, “even in the presence of strong interfering additives.”

In other words, the silver particles still demonstrate antimicrobial effectiveness in spite of the presence of ingredients that should interfere with it.


Here’s a quote from the study:

“The wide antimicrobial spectrum, the high microbicidal potency, the good water solubility and the safety of anodic silver, therefore, provide an encouraging background to the investigation of the use of this ion as a preservative in pharmaceutical or cosmetic formulations…


The high rate of kill of anodic silver is very useful to ensure a rapid reduction of microorganisms. However, the effectiveness of silver in keeping the number of surviving organisms at less than 0.01% of the starting inoculum after repeated inocula, even in the presence of strong interfering additives, appears the most interesting feature for its possible use as a preserving agent in multiple-dose products”.


— Scalzo, M., et al. 1996. Antimicrobial activity of electrochemical silver ions in nonionic surfactant solutions and in model dispersions. Journal of Pharmacy and Pharmacology, 48, 60-63.


[From the “What the Experts Say About Colloidal Silver” page at]

What that basically says is that when manufacturers use ionic silver in cosmetics or in pharmaceutical products as a disinfectant and preservative to help prevent the product from becoming contaminated with bacteria, the silver is able to keep the number of surviving microbes down to less than 0.01% even after the product has been used repeatedly, and even if the product contains “strong interfering additives.”

So the good news is that if you make an all-natural mouthwash, for example, using colloidal silver and other natural ingredients, and you still have some left over after a week or so, it should still be good to use!

What to Watch For

Just be sure to watch for signs that the colloidal silver you’ve mixed with another substance isn’t being neutralized, oxidized or otherwise degenerated over the course of time.

For example, if the solution you’ve made is turning gray, cloudy or murky looking, this is a sure sign the silver particles have lost their electrical charge and are oxidizing and falling out of suspension, or agglomerating with other constituents in the solution you’ve mixed.  That’s when it’s time to mix a new, fresh batch.

As I’ve mentioned previously, to insure maximum potency of the silver, most experienced colloidal silver users agree that fresh batches of such homemade natural products should be made for each individual use.

The exceptions are in cases of mixing colloidal silver with liquid soaps or shampoos (in which cases silver seems to maintain potency indefinitely), some gels (such as Aloe Vera gel, in which colloidal silver seems to maintain potency indefinitely) or in making a natural mouthwash or underarm deodorant spray (in which case experienced users generally make no more than one week’s worth at a time).

Just keep your eye on your homemade solutions to make sure there’s no discoloration in them that would indicate the silver particles are agglomerating or oxidizing and falling out of suspension and thereby losing their potency.



Yours for the safe, sane and responsible use of colloidal silver,
