I recently saw a question on Google that read like this:
“Can you put rubbing alcohol (isopropyl alcohol) on a dog to make him stop licking?”
Are you kidding me? Then I read about a woman who uses isopropyl alcohol to mix the edible frosting colors for a dog birthday cake. Really?
Well, then I did some poking around in the dog product industry. And I suddenly realized that many people think isopropyl alcohol is okay.
It is not!
When you look at the isopropyl alcohol Material Safety Data Sheet, here’s what you’ll see …
Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause kidney damage. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure.
Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Inhalation of vapor may cause respiratory tract irritation.
This is not something I’d ever put on my dog’s skin. Especially somewhere she can inhale or lick it.
Alcohol In Pet Products
Despite the warnings and the research … isopropyl alcohol has been sneaking its way into the cosmetics industry for years. And now it’s found a nice cozy bed in the pet care industry.
The world of alcohol is vast … with many different types of alcohol. And they all serve their purpose in each specific industry that uses them.
Alcohol is used as …
- a solvent (a substance that dissolves another substance)
- an antiseptic
- a humectant (a substance that helps retain moisture)
- a preservative
But the scary part is how alcohol delivers ingredients into the skin. It does it by breaking down the natural oils and antibacterial layer.
Forms Of Alcohol
Alcohol comes in many forms. They’re not all created equal. When most people see alcohol on a label they think of drinking alcohol or spirits. Those are the opposite of isopropyl alcohol.
Here are a few types of alcohols you’ll find …
Ethanol Or Grain Neutral Spirits
Drinking alcohol is what the industry calls undenatured ethanol or grain alcohol. Most alcohol produced in North America is from corn. Natural alcohol can also come from other sources like …
- Sugar cane
Grain alcohol or ethanol is available in different proofs. A grain alcohol’s proof is its ratio of alcohol to water. For example, 190 proof is 95% ethanol and 5% water. When you look at a bottle of alcohol in the liquor store … you’ll see that it says, “__ proof”. The proof is twice the percentage of alcohol. So, 80 proof would mean that the bottle contains 40% ethanol.
Alcohol In Herbal Tinctures
As an herbalist, I use alcohol to extract the active ingredients in plants … to make herbal tinctures. My alcohol of choice is organic grain alcohol because it’s non-GMO and safe in small amounts. Tincture dosages for dogs are usually 1 to 3 single drops.
I prefer alcohol extractions for dogs.
- They’re easily absorbed into the bloodstream. That’s why I call alcohol extracts “predigested herbs.”
- Alcohol extractions don’t need heat, so the plant’s volatile oils are preserved. This makes the tincture more effective.
- And … with proper storage, alcohol tinctures have an unlimited shelf life.
Most dogs are fine with herbal tinctures. The small amount of alcohol makes them very safe. But if your dog doesn’t tolerate herbal tinctures well, here’s the solution.
Dilute the tincture dose with an equal amount of hot water. It’ll cause the alcohol to evaporate.
Organic alcohol is the same as ethanol or grain alcohol … but the fermentation, distillation and packaging processes use organic standards.
Methyl Alcohol or Methanol
Methanol is a highly toxic form of alcohol. It’s also known as wood alcohol. Methanol is used in antifreeze, as a solvent, an industrial cleaner, and in the synthesis of formaldehyde.
Denatured alcohol can be made of ethanol … or sometimes other chemically classified alcohols that are not ethanol based.
This type of alcohol is denatured by the addition of toxic solvents. This makes the alcohol unfit for consumption.
Companies denature alcohol to avoid having to pay taxes. It also stops people from buying ethanol anywhere but a liquor store.
The chemicals used to denature vary. But the most popular are …
- methyl isobutyl ketone
- isopropyl alcohol (rubbing alcohol)
- methyl ethyl ketone
Many of these added chemicals are nearly impossible to distill out of the alcohol. This makes them the toxins of choice for the denatured alcohol industry.
Isopropyl alcohol is touted as a mild antiseptic, cleaner and disinfectant. It’s made through the hydration of water and a carbon called propene. This comes from fossil fuels like petroleum, natural gas and coal.
Why You Should Care About Isopropyl Alcohol
Isopropyl alcohol is rapidly absorbed through your dog’s skin. It has several negative effects.
- Skin irritation and excessive dryness.
- Delays healing of skin tissue.
- Removes the skin’s naturally occurring moisture barrier.
- Can cause respiratory tract irritation when inhaled.
- Is a neurotoxin (harming the nervous system).
- It contains petroleum-based propene, which makes it unfit to drink … and twice as toxic as ethanol.
- The liver oxidizes isopropyl alcohol into acetone. With prolonged exposure this process can damage the kidneys.
Other Names For Isopropyl Alcohol
Isopropyl alcohol has a few other names:
- propyl alcohol
- isopropyl alcohol
- 2-propyl alcohol
- dimethyl carbinol
So … look out for these names when you shop for dog products.
Pet Care Products With Isopropyl Alcohol
Here are two examples of popular pet care products containing isopropyl alcohol.
1. This first product is for use on paws and hot spots. It touts that “your dog would ask for it.” My pug, Francis, has firmly verified that she would not.
Active ingredients: Cod Liver Oil, Gentian Violet, Brilliant Green.
Other Ingredients: Isopropyl Alcohol, Balsam Peru, Glycerine, Cade Oil, Tannic Acid, Turpentine.
I can’t ignore that this product uses a substance called Brilliant Green. This is also known as Zelyonka. It’s a Russian dye that’s toxic when eaten. And it’s likely your dog would eat it. Because the first ingredient is cod liver oil. I don’t know any dog who wouldn’t do her best to lick the fish oil off her skin and paws.
And when she licks the fish oil … in goes the brilliant green, turpentine and isopropyl alcohol as well.
2. The second example is a muscle recovery rub for dogs. This one kind of made me want to go postal.
Ingredients: menthol 20mg/g, camphor 6.25mg/g, isopropyl alcohol 350mg/g in a gel base.
This is an example of a product that may seem natural to some. But it’s anything but. Let’s look at the ingredients:
- 20mg of menthol is too much for a dog … and it can irritate the lungs.
- Camphor should never be used on dogs. It can cause severe issues like seizures and liver failure.
- Isopropyl alcohol.
- The gel base usually contains propylene glycol, copolymers, polysorbates and sodium laureth sulfate.
But those are just two. Manufacturers love to use isopropyl alcohol for many other dog products:
- ear washes and flushes
- all types of skin treatments
- skunk washes
- so-called “pet-safe” household cleaners
- chewing sprays like Bitter Apple
- different types of wipes
- miracle urine cleaners
- paw care products
- wound care sprays
- floor cleaners
There’s another group of alcohols that are generally recognized as safe (GRAS). They’re made from natural fats and oils. This group of fatty alcohols has a different effect on the skin than their ethanol-based counterparts. Most fatty alcohols are emulsifiers (that blend liquids together) and emollients (skin softeners).
Extracted from coconut oil, cetyl alcohol is a foaming emollient and emulsifier. It stabilizes or alters the formula it’s added to. It has a low occurrence of irritation.
Stearyl alcohol is mostly made from coconuts, shea nuts, and sometimes, animals. It’s used as an emollient, emulsifier, and thickening agent. This alcohol is mostly solid at room temperature. It’s soothing and non-drying to the skin.
Cetearyl alcohol is an emulsifying wax. It’s derived from natural oils or fats. It’s very efficient as a stabilizing agent because it gives an emollient feel to the skin.
What Can You Do?
You can avoid isopropyl alcohol with a bit of care. There are natural solutions for every product that contains it.
1. Don’t buy any product that doesn’t provide a full ingredient list.
2. If you come across an ingredient you don’t know … Environmental Working Group’s Skin-Deep database is an excellent place to start.
3. Look for these ingredients instead:
- alcohol-free witch hazel
- apple cider vinegar
- aloe vera juice
- vegetable glycerin
- purified water.
4. If the product needs alcohol, look for grain or organic alcohol from plant sources.
As I said earlier, I use organic grain alcohol to extract plant ingredients when I make herbal tinctures. It’s non-GMO and it’s safe.
There are many other types of alcohol that I haven’t covered. But isopropyl rubbing alcohol is the denatured alcohol you’ll find most in dog products.
The danger of using this form of alcohol definitely outweighs any benefit a manufacture could conceive.
Always Read Labels
Even though some labels can be disheartening, you must read them each time you buy something new. Or even something that you’ve used for a long time. Manufacturers love to change ingredients when you’re not looking.
It’s up to you as a dog owner. You have to do the work it takes to protect your dog from the dangers of modern industry.
