What Are The Ingredients In Voltaren? | Full Label Guide

Why Voltaren Ingredients Matter

When you rub Voltaren on sore joints, you are not only putting diclofenac on your skin. You are also putting a blend of gel base, solvents, fragrance, and other helper ingredients on that same area. If you have allergies, sensitive skin, or you compare brands, those extra names on the back panel start to matter a lot.

Most versions of Voltaren use diclofenac as the only pain-relieving drug. The rest of the ingredient list controls how the gel feels, how well it spreads, how long it stays on the skin, and how diclofenac moves through the upper layers. A closer look at those names can help you spot possible triggers, understand why one gel feels lighter or greasier than another, and decide whether a generic version suits you.

The details in this guide rely on official drug labels for Voltaren Arthritis Pain Gel and Voltaren Emulgel products. Ingredient lists can change, so always match what you read here with the “Drug Facts” or leaflet that came with the tube in your hand.

Voltaren Ingredient List By Product Type

The name “Voltaren” sits on several products around the world. In the United States, the best known version is an over-the-counter arthritis pain gel with diclofenac sodium 1%. In many other countries you will see Voltaren Emulgel with diclofenac diethylamine at regular or extra strength levels.¹

Every one of these products keeps diclofenac as the active ingredient, but the salt form and strength shift a little, and the gel base can shift as well. The table below gives a broad view of how the main Voltaren gels compare.

Voltaren Product	Active Diclofenac Salt	Strength Per 1 g Gel
Voltaren Arthritis Pain Gel (US OTC)	Diclofenac sodium	10 mg (1% diclofenac sodium)
Voltaren Emulgel Regular Strength	Diclofenac diethylamine	11.6 mg (≈10 mg diclofenac sodium)
Voltaren Emulgel Extra Strength	Diclofenac diethylamine	23.2 mg (≈20 mg diclofenac sodium)
Voltaren Emulgel Back & Muscle Pain	Diclofenac diethylamine	1.16% or 2.32% (by market)
Generic Diclofenac Sodium Topical Gel 1%	Diclofenac sodium	10 mg (1% diclofenac sodium)

The ingredient lists in this section draw on the official diclofenac sodium topical gel drug facts label and on Voltaren Emulgel product leaflets used in Canada and other markets.^1,2

Active Ingredient: Diclofenac In Voltaren

Diclofenac belongs to the nonsteroidal anti-inflammatory drug group (NSAIDs). In Voltaren gels it is used at low strength to target pain in joints close to the skin, such as hands, wrists, elbows, feet, ankles, and knees.^3,4

In the United States, Voltaren Arthritis Pain Gel lists diclofenac sodium 1% as the active ingredient. In many Voltaren Emulgel packs outside the United States, the label lists diclofenac diethylamine, a related salt that delivers a similar amount of diclofenac base per gram of gel.^1,2

Once on the skin, diclofenac blocks the formation of prostaglandins, substances that play a big part in joint pain and swelling. Systemic absorption from skin use stays much lower than from tablets, but that lower number does not remove risk. People with past problems from oral NSAIDs still need care with topical forms.^3,4

Non-Medicinal Ingredients In Voltaren Gels

The answer to “what are the ingredients in voltaren?” goes beyond diclofenac. The gel base includes several non-medicinal ingredients that shape texture, spreadability, scent, and shelf life. Names can change slightly by brand and country, yet the groups stay fairly similar.

Gel Base And Texture Ingredients

Most Voltaren gels rely on carbomer, an acrylic polymer, to thicken the product and create that smooth, semi-solid feel on your finger. When neutralized with a small amount of base (such as ammonia or diethylamine), carbomer turns the mix into a stable gel that holds its shape until you rub it out over the skin.^1,2

Macrogol cetostearyl ether (also called polyoxyl 20 cetostearyl ether) and mineral oil or liquid paraffin sit in the base as emulsifiers and emollients. They help keep the oil and water portions blended, stop the gel from separating in the tube, and give the product a softer, more caring feel on dry skin.

Solvents And Spreading Agents

Isopropyl alcohol and propylene glycol show up on nearly every Voltaren gel ingredient list. They work as solvents that help dissolve diclofenac and other ingredients, and they help the gel spread thinly without sticky residue. Propylene glycol also acts as a humectant, drawing a bit of water into the upper layers of the skin, which can help diclofenac move into the target area.^1,2

Cocoyl caprylocaprate (often written coco-caprylate/caprate) is another common name. This light oil comes from coconut and helps the gel feel less tacky, more silky, and easier to rub in. Together, these ingredients shape how fast the gel dries, how glossy it looks, and how your skin feels after application.

Stabilizers, Fragrance, And Neutralizers

Many Voltaren packs list fragrance or perfume, sometimes with a note that it contains benzyl benzoate. This blend gives the gel a mild scent and can mask the natural smell of diclofenac and solvents. People with fragrance allergies may react to this part of the formula, not to diclofenac itself, so the fragrance line deserves attention if you have a history of perfume-related rashes.^2,5

Some versions also include butylhydroxytoluene (BHT) as an antioxidant to slow down oxidation of the oils, plus strong ammonia solution or diethylamine to set the pH of the carbomer gel. Purified water rounds out the list and forms the main base in which the other ingredients sit.

The full blend of carbomer, macrogol cetostearyl ether, cocoyl caprylocaprate, isopropyl alcohol, propylene glycol, mineral oil or liquid paraffin, fragrance, water, and small stabilizers is described in detail in the official Voltaren Emulgel product information used by health professionals.^1,2,5

How Voltaren Ingredients Vary By Country And Brand

Ingredient lists for Voltaren look broadly similar around the globe, yet they are not identical. A tube bought in the United States lists diclofenac sodium 1% and uses one exact set of excipients. A Voltaren Emulgel pack from Canada or Europe lists diclofenac diethylamine and a closely related but not identical list of excipients.^1,2,5

Regulators in each country approve a specific formula. When a drug company updates a gel base or fragrance blend, older tubes in stores may still show the previous list for a while. On top of that, generic diclofenac gels often copy the same general pattern of carbomer, alcohol, propylene glycol, and emollients, yet may choose slightly different grades or suppliers for each one.

Because of these small shifts, ingredient lists you see online always need to be cross-checked against the Drug Facts label or patient leaflet in the box you have at home. That label is the final word for that batch and that country.

How To Read A Voltaren Drug Facts Label

Standing in the pharmacy aisle, the Drug Facts panel or leaflet can look like a solid wall of text. Breaking it into small steps makes it easier to match ingredients with your own needs.

Here is a simple way to work through it:

• First line under “Active ingredient” tells you the diclofenac salt and strength.
• The “Purpose” line confirms that Voltaren in that pack is an arthritis pain reliever.
• Below that, the “Inactive ingredients” list names the gel base and helper ingredients.

When you see longer chemical names, you do not have to memorize them all. Instead, scan for items you already know you react to, such as fragrance, propylene glycol, isopropyl alcohol, mineral oil, or certain preservatives. If any line looks unfamiliar and you have a complex allergy history, bring the pack to your doctor or pharmacist and ask whether that ingredient fits your plan.

If you like to double-check details, you can compare the pack in your hand with the latest online version of the diclofenac sodium gel label on DailyMed or with the current Voltaren Emulgel leaflet from the manufacturer.^1,2

Who Should Pay Extra Attention To Voltaren Ingredients

Some people can scan the ingredient list quickly and move on. Others need a slower, more careful read. If you belong to one of the groups below, spend a bit more time with the label before you reach for the tube.

• Anyone with past allergy to oral NSAIDs such as diclofenac, ibuprofen, or naproxen.
• People who have reacted to fragrance, propylene glycol, or isopropyl alcohol in other skin products.
• People with eczema, very dry skin, or a history of contact dermatitis.
• People who already take other NSAID medicines by mouth.
• Pregnant people and those trying to conceive.

For these groups, both the active ingredient and the excipients matter. Your doctor or pharmacist can help match a specific Voltaren gel or an alternative topical to your health history, other medicines, and skin needs.^3,4

Comparing Voltaren Gel With Generic Diclofenac Gels

In many pharmacies you will see Voltaren Arthritis Pain Gel sitting next to generic diclofenac gels. Most of those generic products share the same 1% diclofenac sodium strength and a broadly similar list of inactive ingredients such as carbomer, coco-caprylate/caprate, isopropyl alcohol, mineral oil, polyoxyl 20 cetostearyl ether, propylene glycol, water, and ammonia.¹

When you compare packs, look at two lines first: the active ingredient line and the inactive ingredient list. Ask yourself:

• Does the generic use the same diclofenac salt and strength as Voltaren?
• Are there any inactive ingredients you already avoid in other skin care products?
• Do you prefer fragrance-free or a scented gel?

A generic diclofenac gel that matches Voltaren on these points can give a similar experience for many users. Still, the exact balance of emollients, solvents, and fragrance may change the feel on the skin and the chance of irritation for some people.

Ingredient Roles In Voltaren Gels

By this stage you have seen many names. It helps to sort them by what they do inside the tube and on your skin. The next table groups the most common names by their main role.

Ingredient	Type	Main Role In The Gel
Diclofenac sodium / diclofenac diethylamine	Active drug	Reduces joint pain and swelling as an NSAID
Carbomer homopolymer Type C	Gelling agent	Builds the gel structure and thickness
Macrogol cetostearyl ether	Emulsifier	Keeps water and oils blended and stable
Cocoyl caprylocaprate	Emollient	Improves spread, leaves a soft skin feel
Isopropyl alcohol	Solvent	Helps dissolve diclofenac and speeds drying
Propylene glycol	Humectant/solvent	Helps water balance and drug movement in skin
Mineral oil / liquid paraffin	Emollient	Softens skin and slows water loss
Fragrance / perfume	Scent	Masks raw smell, gives a mild scent
Butylhydroxytoluene (BHT)	Antioxidant	Protects oils from oxidation over shelf life
Strong ammonia solution / diethylamine	pH adjuster	Neutralizes carbomer and sets gel pH
Purified water	Vehicle	Main liquid base carrying all ingredients

Some packs will list every one of these names, while others skip BHT or use a slightly different emollient blend. The label on your own tube is always the reference for that product.

Frequently Asked Questions

Does Voltaren Contain Any Steroids?

No. Voltaren gels use diclofenac, which belongs to the NSAID group, not to the steroid group. There is no hydrocortisone, prednisone, or similar steroid listed on standard Voltaren ingredient labels.

If a tube lists a steroid in the active ingredient line, it is a different product and should not be treated as Voltaren.

Is Voltaren Fragrance-Free Or Scented?

Many Voltaren Emulgel products list “fragrance” or “perfume” as a non-medicinal ingredient. That blend can include benzyl benzoate and other scent components, which gives the gel its light smell.

In some markets, generic diclofenac gels skip fragrance. If you know fragrance tends to irritate your skin, scan the inactive ingredient list for that line before you buy.

Can I Use Voltaren If I Am Allergic To Propylene Glycol?

Propylene glycol appears on the inactive ingredient list of many Voltaren gels and generic diclofenac gels. People with a known allergy to this solvent can react to these products, even if they have no problem with diclofenac itself.

If your allergy testing named propylene glycol, ask your doctor or pharmacist to help you find a topical pain product that avoids it.

Do Voltaren Tablets And Gels Share The Same Ingredients?

Voltaren tablets share the same active drug, diclofenac, but they use tablet fillers and coatings rather than gel bases. The inactive ingredients in tablets differ from those in topical gels.

People who react to a gel excipient such as fragrance or propylene glycol may still tolerate oral diclofenac, and the opposite can also be true. Each product needs its own review.

How Can I Check If My Voltaren Tube Matches The Latest Label?

Start with the Drug Facts panel or leaflet that came with your pack. Match the active ingredient strength and inactive ingredient list with the details printed on the box or tube.

Then, if you want an extra check, compare your pack with the latest Voltaren or diclofenac gel label on trusted drug information sites or on the manufacturer’s site for your country.

Wrapping It Up – What Are The Ingredients In Voltaren?

Voltaren keeps things simple on the drug side: diclofenac stands alone as the pain-relieving ingredient across gels and Emulgel products. Around that core, each tube carries a crafted mix of carbomer, emollients, solvents, fragrance, and stabilizers that shape how the gel feels and behaves on your skin.

When you read the label, think about two things at once: whether diclofenac as an NSAID fits your health plan, and whether any of the inactive ingredients have caused trouble for you in other skin products. With that habit, you can pick the Voltaren or generic diclofenac gel that suits your joints, your skin, and your comfort level with the ingredient list.
