Barbasol shaving cream is not toxic when used as intended, but it does contain several ingredients that carry moderate safety concerns, particularly for people with sensitive skin or allergies. The Environmental Working Group rates the original formula a 3 out of 10 on its hazard scale, which it labels “high hazard” relative to other personal care products. That doesn’t mean it’s dangerous to shave with, but it’s worth understanding what’s actually in the can.
What’s in Barbasol Original
The ingredient list for Barbasol’s original formula is relatively short: water, stearic acid, isobutane, triethanolamine, laureth-23, sodium lauryl sulfate, propane, and fragrance. Stearic acid is a fatty acid that creates the cream’s texture and is considered safe. Water is obviously harmless. The rest of the list is where things get more interesting.
Barbasol does not contain parabens or phthalates, two categories of chemicals that have drawn scrutiny for potential hormone-disrupting effects. The company confirms this on its FAQ page for all Barbasol products.
The Ingredients That Raise Flags
Three ingredients in Barbasol carry the most concern: fragrance, triethanolamine, and the aerosol propellants.
Fragrance scores an 8 out of 10 on the EWG hazard scale, making it the highest-rated concern in the formula. “Fragrance” is a catch-all term that can represent dozens of undisclosed chemical compounds. Manufacturers aren’t required to list them individually because fragrance formulas are considered trade secrets. The concern is that fragrance blends frequently contain allergens and compounds linked to moderate endocrine (hormone) disruption. If you’ve ever had skin irritation from a scented product, this is the most likely culprit in Barbasol.
Triethanolamine scores a 6 out of 10. It acts as an emulsifier, helping the oil and water components blend together. The primary concern is contamination with nitrosamines, a class of compounds formed when triethanolamine interacts with certain other ingredients. Nitrosamines are considered potential carcinogens. The cosmetics industry safety panel has deemed triethanolamine safe for use in cosmetics with concentration limits, and the EU restricts its use in cosmetic products. In a rinse-off product like shaving cream, which stays on your skin briefly, the exposure is lower than it would be in a leave-on lotion or moisturizer.
Isobutane and propane are the aerosol propellants that push the cream out of the can. Both score a 3 on the EWG scale. In the tiny amounts released during a normal shave, they pose minimal risk. The real concern with these gases is inhalation in concentrated amounts: high exposure can cause dizziness, irregular heartbeat, and in extreme cases, loss of consciousness. This is relevant if you’re spraying in a small, poorly ventilated bathroom for an extended period, but a quick burst onto your hand is a very different scenario. Isobutane also carries a contamination concern for trace amounts of butadiene, a known carcinogen, though the levels present in consumer aerosol products are extremely small.
Skin Irritation and Contact Risks
Sodium lauryl sulfate (SLS) is a foaming agent found in everything from shampoo to toothpaste. It’s a known skin irritant, especially for people with eczema or sensitive skin. It won’t cause long-term harm for most people, but if your face feels tight, red, or itchy after shaving with Barbasol, SLS is a likely contributor alongside fragrance.
Barbasol’s non-aerosol therapeutic shave cream (a different product from the classic can) has a pH of 12, which is quite alkaline. Its safety data sheet notes that prolonged contact with skin can cause caustic burns. The standard aerosol version doesn’t carry this same warning, but it’s a good reminder that shaving cream is meant to be rinsed off promptly, not left sitting on your skin.
If swallowed, Barbasol can cause gastrointestinal distress. The recommended first aid is to drink water and seek medical attention without inducing vomiting. This matters mostly for households with young children who might be attracted to the foam.
Barbasol Sensitive Skin: Is It Safer?
Barbasol’s Sensitive Skin formula uses the same base ingredients as the original, including triethanolamine, isobutane, propane, SLS, and fragrance. The main additions are thyme extract, papaya fruit extract, willow bark extract, and aloe. These botanical ingredients may soothe skin, but the formula doesn’t actually remove any of the ingredients that carry the highest hazard ratings. If fragrance is your concern, the Sensitive Skin version still contains it.
Putting the Risk in Perspective
Shaving cream is a rinse-off product. You apply it, shave for a few minutes, and wash it away. That brief contact time significantly limits how much any ingredient can absorb into your skin compared to a moisturizer or sunscreen you wear all day. The concentrations of concerning ingredients like triethanolamine are also regulated, and the cosmetics industry safety panel has reviewed them specifically for use in products like this.
The realistic risks from Barbasol are skin irritation and allergic reactions, not acute poisoning or serious toxicity. People with sensitive skin, fragrance allergies, or conditions like eczema are the most likely to have problems. For everyone else, the formula is broadly comparable to most mainstream aerosol shaving creams on the market, which use similar propellants, surfactants, and fragrance blends.
If you want to reduce your exposure to the flagged ingredients, look for shaving creams that are fragrance-free (not “unscented,” which can still contain masking fragrances), SLS-free, and sold in tubes rather than aerosol cans. These changes eliminate the three categories that account for most of the hazard rating in Barbasol’s formula.
