Is Cocofloss Clean? The Truth About The Cult-Favorite Floss

📅 Updated February 2026⏱️ 4 min readNEW

TL;DR

Cocofloss is a massive upgrade over conventional Teflon-coated flosses because it is strictly PFAS-free. However, it is not 100% natural. The floss is made of polyester (plastic), coated in petroleum-derived microcrystalline wax, and most flavors contain synthetic fragrances. If you want the cleanest option, stick to their Delightful Mint flavor.

🔑 Key Findings

1

Cocofloss is completely free of PFAS and PTFE (Teflon).

2

The floss string is made from 85% recycled polyester, which is plastic.

3

It uses microcrystalline wax, a highly refined petroleum byproduct, instead of natural plant or beeswax.

4

All flavors except "Delightful Mint" use a blend of natural and synthetic fragrances.

The Short Answer

Cocofloss is completely PFAS-free, making it far safer than conventional slippery tape flosses. However, it is not entirely natural.

The floss is made from recycled polyester, coated in a petroleum-derived wax, and relies on synthetic fragrances for its trendy fruit flavors. If you love the brand's plaque-grabbing texture, stick to the Delightful Mint flavor—it's the only one that uses 100% natural essential oils.

Why This Matters

Floss goes directly into your bleeding gums and bloodstream. Conventional flosses are notorious for being coated in PTFE (Teflon)—the exact same toxic forever chemicals (PFAS) used in non-stick pans. Is There Pfas In Floss

Because of this, consumers are frantically searching for clean alternatives. Cocofloss positions itself as a premium, non-toxic savior. But "PFAS-free" does not automatically mean "natural." What Floss Is Pfas Free

While Cocofloss avoids the most dangerous chemicals, it still uses plastic and petroleum derivatives. If your goal is a zero-waste, 100% natural routine, Cocofloss falls short. But if you just want to avoid the forever chemicals found in mainstream drugstore brands, it's a massive upgrade. Safest Dental Floss

What's Actually In Cocofloss

  • Recycled Polyester — The string itself is made of 85% recycled plastic water bottles. It's great for the environment, but it is still plastic (microplastics) and is not biodegradable.
  • Microcrystalline Wax — This gives the floss its "slip." Unlike natural beeswax or candelilla wax, microcrystalline wax is derived from petroleum.
  • Coconut Oil — A genuinely clean ingredient. Coconut oil acts as a natural antimicrobial to soothe gums and fight bacteria.
  • Synthetic Fragrance — To achieve fun flavors like "Cara Cara Orange" and "Vanilla Bean," Cocofloss uses a blend of natural and synthetic aromas. Only the Mint flavor is 100% natural.

What to Look For

Green Flags:

  • PFAS-Free — Cocofloss guarantees their product is free from toxic forever chemicals. Which Floss Has Pfas
  • Textured Weave — The 500+ interwoven filaments act like a loofah, physically scrubbing away plaque rather than just sliding over it.

Red Flags:

  • Synthetic Fragrances — Hidden under proprietary "aromas" to create their unique fruit flavors.
  • Petroleum Wax — A refined byproduct of the oil industry that goes directly into your gumline.

Avoid
🚫

Smooth Slide Floss Mint

Up & Up (Target)

This generic store-brand floss tested over 70,000 ppm for organic fluorine in recent consumer studies. The 'smooth slide' marketing is a major red flag that the product relies on toxic chemical coatings rather than natural waxes.

Avoid

Solimo (Amazon)

Another budget-friendly store brand that failed independent lab testing, showing over 70,000 ppm of organic fluorine. It utilizes synthetic PTFE-like compounds to aggressively mimic the texture of premium glide flosses.

Avoid
🚫

Glide Deep Clean Cool Mint Floss

Crest

The entire 'Glide' family of products was originally invented using Gore-Tex fibers and is heavily reliant on PTFE. Independent testing has repeatedly linked these slippery tapes to elevated levels of perfluorohexanesulfonic acid (PFHxS) in human blood.

Avoid
⚠️

Burst

Despite its eco-friendly refillable marketing, independent laboratory testing found 208 ppm of organic fluorine in this floss. While lower than traditional glide flosses, it highlights the problem of greenwashing when forever chemicals are still present.

Use Caution
⚠️
Smart Floss

drTung's

Highly popular in natural health circles, but an independent consumer study detected 48 ppm of organic fluorine in this specific product. Although it is free of petrochemical waxes, the presence of PFAS markers means purists should look for verified non-detect alternatives.

Use Caution
⚠️

Bamboo Floss

EcoRoots

This zero-waste floss is marketed as a pristine eco-friendly option, but lab tests revealed 14 to 23 ppm of organic fluorine across multiple samples. It illustrates the severe issue of unintentional PFAS contamination within the supply chain of commercial bamboo processing.

Use Caution
⚠️

Listerine

Independent testing found 16 ppm of organic fluorine in this mainstream tape. Additionally, the ingredient profile relies heavily on petroleum-derived microcrystalline wax and synthetic polymer coatings to prevent shredding.

Use Caution
🚫

EaseBetween Original Dental Floss

CVSHealth

Modeled directly after mainstream slippery flosses, this drugstore generic relies on synthetic PTFE fibers to prevent snapping. Because it uses the exact same core materials as premium glide brands, it carries a severe risk of exposing your gum tissue to toxic fluorinated compounds.

Avoid
⚠️

Thieves Dental Floss

Young Living

While it uses high-quality essential oils like clove and peppermint, the string is heavily coated in microcrystalline wax. This wax is a highly refined byproduct of the petroleum industry, making it less than ideal for a strictly natural oral care routine.

Use Caution
🚫

Avoid
⚠️
