SDS of the Week: Mycomist Spray – The Mold Killer with a Secret

‍

At first glance, Mycomist Spray looks like your average hospital fungicide—a small, 4 oz aerosol meant to knock out mold and mildew in medical settings. But peek under the cap (or better yet, into the SDS), and things start to get a little... spicy.

While the packaging screams “sterile efficiency,” the contents whisper something more flammable, more toxic, and frankly more surprising.

🔍 So What’s in the Can?

According to its Safety Data Sheet, Mycomist Spray contains:

• Isopropyl Alcohol (45–50%) – Classic flammable solvent
  
  
• Paraformaldehyde – Yup, the same stuff used in embalming fluid. This is the heavy hitter for fungal annihilation.
  
  
• Propellant – Not specified, but assume it's a pressurized gas that helps this concoction make its airborne debut
  
  

🚨 Classification Highlights

This little 4 oz can comes with a hazard cocktail that includes:

• Flammable Liquid – Category 2
  
  
• Acute Toxicity – Inhalation
  
  
• Carcinogenicity – Category 1B
  
  
• Skin & Eye Irritation – Category 2
  
  

Yes, you read that right—Category 1B Carcinogen. The paraformaldehyde makes this a no-joke classification challenge. Depending on how and where this product is stored, used, or disposed of, you're stepping into OSHA, DOT, and possibly RCRA territory.

🧬 What Makes This a Compliance Curveball?

At first glance, it’s just another surface spray in a sea of cleaners. But...

• It’s technically a pesticide – regulated under FIFRA, not TSCA.
  
  
• It contains paraformaldehyde – a substance banned or restricted in certain states (especially for indoor use).
  
  
• It’s pressurized AND flammable – so storage and transport fall under strict DOT flammable aerosol rules.
  
  
• It's used in clinical or sensitive settings – increasing regulatory scrutiny in healthcare compliance.
  
  

🧼 The Bottom Line

Mycomist may be fighting fungi, but it’s also raising red flags across regulatory agencies. A small can that packs a serious classification punch, it’s the kind of product that looks routine—until your EHS team starts sweating.

Remember: Not all hospital-grade cleaners are created equal. Some come with formaldehyde and a flammability rating.

💡 Pro tip: If you’re managing regulated CPGs in healthcare or retail environments, don’t let “clinical” fool you. Dig into the SDS, because even a mold spray can trigger complex compliance obligations.
