Fabrics, especially those for furniture, and carpets are typically treated for soil, stain, and water resistance with per-and poly fluoroalkyl substances (PFAS). Scotchgard is one well-known brand that has historically been made of PFAS (though now Scotchgard is no longer a PFAS-based treatment).
But many people have health concerns and environmental concerns with these “forever chemicals”.
Some companies make stain-resistant upholstery fabrics and carpets that are free of PFAS, but they do not list which chemicals they have used to replace them.
A review of the literature shows that non-fluorinated stain guard treatments are most likely acrylic, polyurethane, silicon dioxide, or silica coatings.
I list a few brands that claim to be PFAS-free.

Brands of Fabric Protectors (Free of PFAS)
1. ProtectME Premium Fabric Protector
This fabric protector spray is based on nano silicon dioxide and water (nothing else) and is odorless. They claim it’s free of PFAS/PFC and biodegradable (a spray made with PFAS would not be biodegradable).
Silicon dioxide is used in supplements but it is not totally non-toxic. Please review it’s toxicity profile which is not covered here.
It can be used on any type of fabric, from clothes, to sofas, furniture, purse, backpacks, shoes, car seats, etc and it will not change the look, feel, or smell.
2. ProofPlus Home Fabric Protector
This is another option that says it’s free of PFAS/fluoropolymers. (Also, the propellant is just air).
The safety data sheet reveals it’s made of amorphous silica CAS 7631-86-9, a synonym of silicon dioxise. On SharkTank they say it’s made of nanoparticles, is non-toxic, and someone sprays it in their mouth as a demonstration.
Silicon dioxide is used in supplements but it is not totally non-toxic. Please review it’s toxicity profile which is not covered here.
It does not change the look or feel of fabric they say.
They do not recommend the product on suede, leather, or synthetic leather. It is safe to use on cotton, linen, polyester, canvas, rugs, & more.
They have four unscented formulas:
- One for babies: to be used on Bassinets, Car Seats, High Chair Cushions, Baby Shoes, Play Mats, Pack & Plays
- One for outdoor gear: to be used on Jackets, Hats, Grill Covers, Mittens, Patio Furniture, Hiking and Camping Gear
- One for shoes: to be used on Slips Ons, Athletic Sneakers, Flats, Heals, Dress Shoes, Hiking Boots
- One for upholstery and cars: to be used on Sofas, Chairs, Rugs, Carpet, Car Seats
3. Graphenoil Fabric Spray
This spray says it’s made with nano-graphene and Titanium Dioxide (TiO2). I have reached out to confirm that it’s free of PFAS but did not hear back.
This type of formula was not mentioned in the patents I looked at so I know less about it.
A Review of the Literature
Acrylic, Polyurethane, silicon Dioxide, Silica Alternatives
A 2015 patent describes the current common non-per and polyfluoroalkyl substances (non-PFAS) used as water and dirt-repellant fabric treatments are made mainly of copolymers based on polyacrylates or urethanes. (ie. acrylic or polyurethane plastic coatings). (source)
Another 2015 patent that is active and was filed in many countries outlines a stain-resistant coating for carpets based on nanoparticulate silicate clay and an acrylic-based copolymer. (source)
In an overview of the industry written by DuPont, they outline the preferred non-fluorinated (non-PFAS) soil-resistant agents, which include:
- polymethylmethacrylate (acrylic)
- methyl methacrylate/ethyl methacrylate copolymer (acrylic)
- an alkali metal salt of a hydrolyzed styrene maleic anhydride copolymer or of a hydrolyzed styrene/maleic anhydride/cumene terpolymer
- an ammonium salt of a hydrolyzed styrene/maleic anhydride copolymer or of a hydrolyzed styrene-maleic anhydride/cumene terpolymer
- amorphous silicon dioxide
- colloidal silica and amorphous silica
- (source)
Silicone-Based Alternatives
A 2014 patent that pertains to non-fluorinated stain guard carpet coatings describes a textile treatment made of silicone and quaternary ammonia. The patent is active and was filed in many countries around the world (source).
And in two other patents, one by 3M regarding carpet, and one for textiles by a Chinese company, they outline a silicone-based stain-resistant coating (source and source).
Supreen fabric uses a silicone-based (non-PFAS) treatment.
Conclusions
Based on the reading of all the patents I could find on this topic:
- I would expect the main PFAS-free stain and water-resistant coatings to be based on acrylic, polyurethane, or silica or silicon dioxide
- I would not expect non-fluorinated stain-resistant coatings to contain bisphenols like BPA
- I would not expect non-fluorinated stain-resistant coatings to contain phthalates
- It is possible for stain-resistant coatings to contain formaldehyde
- It is possible that stain-resistant coatings can contain soy protein as just one component. If they claim that they use a “soy-based” or “bio-based” stain-resistant coating I would not expect that to be wholly accurate to explain the entire coating

Bottom line, do you feel crypton performance fabric is toxic to humans based on non knowing what’s in their patented fabric?
