Does Febreze remove odors or merely mask them? Here's the chemistry behind how Febreze works, including information about its active ingredient, cyclodextrin, and how the product interacts with odors. Show
Febreze was invented by Procter & Gamble and introduced in 1996. The active ingredient in Febreze is beta-cyclodextrin, a carbohydrate. Beta-cyclodextrin is an 8-sugar ringed molecule that is formed via enzymatic conversion of starch, usually from corn. The cyclodextrin molecule resembles a doughnut. When you spray Febreze, the water in the product partially dissolves the odor, allowing it to form a complex inside the "hole" of the cyclodextrin doughnut shape. The stink molecule is still there, but it can't bind to your odor receptors, so you can't smell it. Depending on the type of Febreze you're using, the odor might simply be deactivated or it might be replaced with something nice-smelling, such as a fruity or floral fragrance. As Febreze dries, more and more of the odor molecules bind to the cyclodextrin, lowering the concentration of the molecules in the air and eliminating the odor. If water is added once again, the odor molecules are released, allowing them to be washed away and truly removed. Some sources say that Febreze also contains zinc chloride, which would help to neutralize sulfur-containing odors (e.g., onions, rotten eggs) and might dull nasal receptor sensitivity to smell, but this compound is not listed in the ingredients, at least in the spray-on products.  Don’t settle for masking odors—Febreze has the technology to fight bad odors at the source. The good news: Fighting odors isn’t rocket science… but it does take a little bit of chemistry know-how to do it right. Read on to learn why the technology in Febreze is designed with the safety of you, your family, and your pets in mind.Febreze: tackling bad odors with good science No fluff in your fresh air! Febreze gets to the point on fighting odor… down to the molecular level. We found four enemies to stinky smells and combined them (science!) to fight bad odors. You might be surprised to recognize some of them: Find it in: It’s the bubbly in your club soda, and the fresh zest in citrus and pine needles. What it does: These zesty molecules fight bad smells by balancing out their pH (so they become as neutral as water). Find it in: summer sweet corn and potatoes What it does: This donut-shaped molecule traps odors in its center. Find it in: Febreze! This polymer was specially created to tackle odors in hard-to-wash fabrics. What it does: This odor magnet digs deep to draw out odors, then traps them while releasing bursts of freshness. Find it in: Flowers, fruits, and fresh rain! We re-created natural scents in Febreze by replicating their molecular composition. What it does: These various perfume molecules react and bind to bad odor, thus forcing them to change their stinky ways. natural or synthetic: Is there really a difference? Often, there is no difference between natural and synthetic ingredients; that’s why many of them are called “nature identical.” Yep, the ingredients used in our air fresheners are identical to their natural counterparts. When examined under a microscope, they look exactly the same. So when you smell a lavender fragrance molecule that’s created in a lab, it’s indistinguishable from the scent of lavender growing in your yard. Febreze takes a responsible approach to fragrance, opting for synthetics when choosing a botanical that could be harmful to the environment… or even strip away a rare plant species. A molecule from a fresh orange vs. the orange essence used in Febreze So now you know: There’s no secret to the stink-busting power of Febreze. Just good, clean science. Doesn’t that feel like a breath of fresh air? Febreze is an American brand of household odor eliminators manufactured by Procter & Gamble. It is sold in North America, South America, Europe, Africa, Asia, Australia, and New Zealand. First introduced in test markets in March 1996,[1] the fabric refresher product has been sold in the United States since June 1998, and the line has since branched out to include air fresheners (Air Effects), plug-in oil (Noticeables), scented disks (Scentstories), odor-eliminating candles, and automotive air fresheners. The name Febreze is a portmanteau of the words "fabric" and "breeze". The name is a popular example of the Mandela effect, with many people claiming to remember the name being previously spelled "Febreeze", despite there being no indication or evidence of the product name having actually been changed.[2][3][4][5] In many non-English speaking countries such as Nepal, the products are sold as Ambi pur. IngredientsThe active ingredient in several Febreze products is hydroxypropyl beta-cyclodextrin (HPβCD). The molecule traps and binds volatilized hydrocarbons within its structural ring, retaining malodorous molecules, which reduces their volatility and thus the perception of their scent.[6] The active ingredient is produced from corn cobs.[7] The use of cyclodextrin as a sprayable odor absorber was patented by Procter & Gamble.[8] The products include additional ingredients such as emulsifiers, preservatives, and perfumes. Benzisothiazolinone is a preservative included in some of the products.[9] LinesThere are many types of Febreze branded products. For example, the main Febreze products are air freshener sprays, which are claimed to have a disinfectant effect. There are specialized ones for odor from pets, for cars, and for fabric. Some are aromatic and others are odorless.
In other countries, there are Febreze products for house dust and toilet facilities. MarketingThe product was initially marketed as a way to get rid of unpleasant smells, it sold poorly until P&G realised that people become accustomed to smells in their own homes, and stop noticing them even when they are overpowering (like the smell of several cats in a single household). The marketing then switched to linking it to pleasant smells and good cleaning habits instead, which resulted in a massive increase in sales. Only after the product became well established in the marketplace did the marketing go back to emphasising odour elimination properties as well.[10] The Veterinary toxicology experts working for the ASPCA Animal Poison Control Center consider Febreze fabric freshener products to be safe for use in homes with pet dogs, cats, ferrets, rabbits, and rodents.[11] However, the package labeling indicates that the product is considered not safe around birds, and results from testing with other animals are not indicated.
