This product contains material that can break down into soil in either a backyard or industrial composting system. These products are declared compostable by the manufacturer, but may not third-party certified. Contact your local waste-hauler or composting facility to determine where these materials may be accepted. Certain materials may be better fit for industrial facilities than backyard composting systems. Industrial facilities may not exist in your area.

Paraben Free

Parabens are synthetic chemical preservatives, commonly used in beauty products like shampoo, lotion, and deodorants. Parabens can accumulate in your body, and have been linked to hormonal disruption and reproductive problems. In studies of breast cancer patients, parabens have been found in the tissue of cancerous tumors–yikes! If you want to avoid Parabens in your beauty products, keep an eye out for methylparaben, propylparaben, butylparaben, and ethylparaben in the ingredients list.

Phthalate Free

Phthalates are found in toys, electronics, personal care products, plastic wraps, containers, and more. These petroleum based chemicals help soften plastics, and bind fragrances to perfumes, deodorants, creams, and other personal care products. Phthalates are are not chemically bound, meaning they can easily get released into the air, water, or your body, just by using the products as intended. Phthalates have been found to disrupt the endocrine system, which can cause reproductive damage, hormonal imbalances, infertility, mood changes, metabolism changes, and more.

About the Company


At RADIUS, they don’t do anything halfway. By taking a holistic approach to designing and manufacturing products, they’re able to stay rooted in their commitment to sustainability and a reduced carbon footprint. Before they create a product, they do a “360 degree evaluation”, considering the entire life cycle of the product from birth to end of life. This evaluation is just one of the many reasons that RADIUS toothbrushes consistently outlast the competition.

By manufacturing locally in the USA, they ensure maximum quality products with less transportation emissions. All products are made small-batch style on low-energy machines, recycling damaged or imperfect toothbrushes, and eliminating waste as much as possible. Instead of using traditional plastic, they employ bioplastics, derived from renewable biomass sources like vegetable oils or used plastic bottles. Not only are these materials better for the environment, but they require less fossil fuels and energy to produce! Click below to learn more about why EarthHero loves RADIUS!

    I’ve been trying to find a more earth-friendly floss for ages and bought this and some bamboo for the household to try. I found both types worked just fine, no breakages; however, I think my partner has sharp edged teeth as it kept breaking – they prefer the bamboo – I can use either. Don’t expect a ‘gliding’ effect – it does the job for me though.

    This floss is great. I like it better than any I’ve used before. It is strong and easy to grip onto. Of course, I love that the box is not plastic.

    For me this silk floss is much too thin and breaks too easily. It doesn’t work for me. I wish it did.

    Great stuff.

    I didn’t think I would like the texture of this at first, but it really cleans well with no breaking or fraying. Easy to use even for someone used to the slick plastic floss.

    Pretty great

    The floss works, love that it is biodegradable. The only issue I have with the product is that if you have teeth pretty close together, like me, it breaks after flossing between a few teeth.

    So far so good

    orangecappy (verified owner)

    I recently have actually been in the habit of flossing every night. I was using a laminated floss, and this definitely has a different texture on my teeth. However it seems to function equally well; if feel a bit rough, and I enjoy being able to throw it in the compost afterward. However I would like if they upgrade their packaging to be more compostable as well. Some floss products come in a paper box; this would be better than the plastic container this is in.

    Replace your plastic floss!


    I love it and can’t wait to place my order with EarthHero. I first bought this product at Whole Foods and was terribly disappointed when they stopped carrying it – and didn’t replace it, either. Silk floss provides a superior result on my teeth because of its texture (think about it – slippery plastic for cleaning out between your teeth???) and the Radius product was just right in all ways. Thank you, EarthHero!

    Great floss!


    Most floss comes in bulky packaging. This floss is compact, thin, and works perfectly well.
