What 3m 47155 Scotchgard Auto Fabric is made of, ingredients and materials
3M Scotchgard Auto Fabric and Upholstery Protector is a proprietary liquid spray coating designed to bond to fabric fibers and repel water and oil-based stains. The exact chemistry is not publicly disclosed; 3M has not confirmed whether the formulation contains fluorinated compounds (PFAS), silicone-based polymers, or other resin systems. Without ingredient transparency, assessment of off-gassing, residue toxicity, or environmental persistence is impossible for consumers.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
PFAS
3M has not disclosed whether this formulation contains perfluorinated or polyfluorinated compounds; older Scotchgard products did contain PFOA. Absence of confirmation is not absence of risk.
Source, ATSDR ↗Spray inhalation and respiratory irritation during application
Aerosol fabric protectors can deposit fine particles in the respiratory tract. SDS data for similar formulations flags potential irritation from propellants and polymeric resins; proper ventilation during spraying is essential.
Residual volatile organic compounds (VOCs) post-application
Solvent carriers in fabric spray coatings may off-gas during drying. No independent testing data for this specific product is on public record, but off-gassing is typical of polymer coatings in enclosed vehicle cabins.
Contact irritation or allergic sensitization from uncured coating
Wet or partially cured coating can cause skin or mucous membrane irritation if touched before full drying. Individuals with fragrance or polymer sensitivities should avoid contact during application and curing.
PFAS
If the coating contains PFAS, fluorinated compounds are known to persist in groundwater and accumulate in blood serum. Consumer use contributes to environmental load, but risk to individual users is lower than manufacturing or disposal exposure.

The brand's record and disclosure
3M has a long history of Scotchgard products but has not publicly committed to PFAS-free formulations or disclosed the chemical composition of this auto fabric variant. The company faced significant litigation over PFOA in older Scotchgard formulas (reformulated in 2000) but has remained silent on current coating chemistry. No third-party certification (GOTS, OEKO-TEX, or similar) is listed for this product.
How it compares in its category
Fabric protector sprays span a wide range of chemistry, some use silicone-based water repellents (lower persistence concern), others rely on fluorinated compounds (PFAS, higher environmental and bioaccumulation risk). This product's anonymized formula places it in a middle ground of uncertainty. Consumer alternatives include mechanical barriers (seat covers), natural fiber treatments (beeswax, soap-based finishes), or PFAS-free certified brands, though effectiveness varies.
If you buy it
Apply only in well-ventilated spaces or outdoors; inhalation of spray aerosol or vapors during application is the primary exposure route. Allow 24-48 hours drying before contact, especially for children and pets. Reapplication is typically needed every 12-24 months depending on use. If you prefer to avoid uncertainty, request 3M's Safety Data Sheet (SDS) and ask the company directly whether the formulation contains PFAS or fluorinated compounds; absence of voluntary disclosure is a signal to consider alternatives.
