Every No Nines™ formula is built to the documented No Nines™ Standard™. Carol, who's a Master's-degreed Chemical Engineer, evaluates every ingredient for safety, performance, and scientific integrity before it earns a place in the formula.
No Nines was created by Carol Krska, a chemical engineer (M.S.) who spent years studying what goes into the products families use every day. She did not like what she found. Conventional cleaners are full of ingredients that do not belong on your skin, in your lungs, or down your drain. So she formulated a full line without them – using clean, effective chemistry that works as hard as anything on the shelf, without the harsh tradeoffs.
Woman-formulated. Crafted in Kansas, USA.
The story behind the standard
The No Nines™ Standard™
Nine categories of harsh chemicals. Zero place in your home.
Most conventional cleaners rely on ingredients linked to skin irritation, respiratory sensitivity, and environmental harm. We drew a hard line. The No Nines Standard is our promise: these nine chemical categories will never appear in our formulas. Not in small amounts. Not hidden behind the word “fragrance.” Not ever.
