At Koh, we proudly claim that our products are fume-free—but what does that actually mean? Some customers have asked about this, especially since a few of our cleaning solutions have a mild scent due to the ingredients we use. Let’s break it down, explain why fume-free doesn’t mean scent-free, and how independent certifications like GECA and Sensitive Choice support our commitment to safer cleaning.
Fume-free vs. fragrance-free: what’s the difference?
- Fume-free means our products do not contain or release high levels of volatile organic compounds (VOCs) that evaporate into the air and linger in your home. Many traditional cleaning products contain ammonia, chlorine, or petroleum-based solvents that can create strong fumes, which may contribute to respiratory irritation, headaches, or poor indoor air quality.
- Fragrance-free means we don’t add synthetic perfumes or essential oils that can trigger asthma, allergies, or sensitivities. Many “green” or “natural” products still contain plant-derived fragrances, but at Koh, we leave them out entirely.
One of the biggest concerns with fragrances is that they often contain phthalates—a group of chemicals used to help scents stick to surfaces for longer. Phthalates have been linked to endocrine disruption, meaning they can interfere with hormone function. Some studies have linked phthalate exposure to reproductive issues, developmental problems, and even certain cancers. Many cleaning products—including those labeled as "natural"—can still contain hidden fragrance chemicals that contribute to indoor air pollution.
By choosing fume-free and fragrance-free products like Koh, you’re reducing your exposure to these unnecessary chemicals.
Why do some Koh products have a mild scent?
While Koh products are fragrance-free, some may have a subtle scent. For example, Cocamidopropyl Betaine, a surfactant derived from coconut oil, is used in some of our formulations to enhance their cleaning power.
This ingredient helps break down dirt and grease while being gentle on skin and low in irritation potential. Unlike artificial fragrances, Cocamidopropyl Betaine does not evaporate into the air, meaning it doesn’t contribute to airborne irritants. Any mild scent that remains is simply a byproduct of the raw materials used in the formulation.
The role of GECA & Sensitive Choice certifications
Koh products meet the standards set by GECA (Good Environmental Choice Australia) and the National Asthma Council’s Sensitive Choice program. These programs provide independent assessments of products to determine if they meet criteria relating to environmental and health impacts.
- GECA certification evaluates products for environmental impact, human toxicity, and VOC levels, among other factors.
- Sensitive Choice approval helps consumers identify products that are considered a better choice for people with asthma and allergies.
These certifications provide independent verification that supports our commitment to developing products with low environmental impact and minimal respiratory irritants.
So, is Koh really fume-free?
Yes! Even though some ingredients have a mild scent, our products are still considered fume-free because:
- No artificial fragrances or hidden scent-masking agents (which often contain phthalates)
- No added VOCs or harsh chemicals that contribute to indoor air pollution
- GECA and Sensitive Choice certified, reinforcing our commitment to safer, more eco-conscious cleaning solutions
You can clean with confidence, knowing you’re not breathing in anything harmful.
