When you read a product label, you might see a list of scientific names that look harmless. But many of these are silent saboteurs, posing a risk to both human and pet health. Here’s a breakdown of the most common culprits and their impact.

1. Phthalates

• What they are: These chemicals are often hidden under the umbrella term “fragrance” and are used to make scents last longer.
• Impact: Phthalates are known endocrine disruptors, meaning they can interfere with our hormones. For humans, this can lead to developmental and reproductive issues. For pets, who are much smaller and spend a lot of time on the floor where these chemicals settle, exposure has been linked to thyroid problems and even certain types of cancer.

2. Ammonia

• What it is: A common ingredient in glass cleaners, floor polishes, and all-purpose sprays.
• Impact: Inhaling ammonia fumes can cause severe irritation to your eyes, skin, and respiratory system. For pets, with their heightened sense of smell, these fumes are particularly irritating and can lead to coughing, burning of the nasal passages, and even damage to their lungs. Never, ever mix ammonia with bleach, as this creates a deadly gas called chloramine.

3. Bleach (Sodium Hypochlorite)

• What it is: A powerful disinfectant found in many common household cleaners.
• Impact: Bleach releases corrosive fumes that can cause serious irritation and chemical burns upon contact with skin and eyes. For pets, inhaling these fumes can lead to chemical pneumonitis, a dangerous inflammation of the lungs. If ingested—even a small amount—it can cause severe gastrointestinal and internal burns.

4. Quaternary Ammonium Compounds (Quats)

• What they are: Found in many disinfectants, fabric softeners, and laundry detergents. They are often listed as “Quats” or under names like Benzalkonium Chloride.
• Impact: Quats are known respiratory irritants and have been linked to the development of asthma in humans. For our furry friends, prolonged exposure can lead to skin irritation and is known to be an endocrine disruptor, potentially affecting their immune system and reproductive health.

5. Glycol Ethers

• What they are: These are solvents found in degreasers, stain removers, and all-purpose cleaners. Look for names like Butoxyethanol or Ethylene Glycol.
• Impact: Glycol ethers are easily absorbed through the skin and can be inhaled. They can cause eye, throat, and respiratory irritation. Long-term exposure has been linked to potential damage to the liver and kidneys in both humans and animals.

6. Artificial Fragrances

• What they are: The single biggest “vibe killer” in the cleaning aisle. This one word can hide over a hundred different synthetic chemicals.
• Impact: Fragrances are one of the most common causes of allergic reactions, headaches, skin rashes, and respiratory issues in humans. For pets, whose noses are thousands of times more sensitive than ours, these strong synthetic odors can cause everything from chronic sneezing to severe respiratory distress.
