What 303 Products 16oz. Fabric Guard is made of, ingredients and materials
303 Products Fabric Guard is a proprietary water-repellent spray coating designed to bead and shed moisture on textiles, outdoor fabrics, and upholstery. The exact chemical composition is not publicly disclosed. Water-repellent finishes on fabric typically rely on fluorinated compounds (PFAS), silicone-based polymers, or wax emulsions to create their durable, hydrophobic effect. Without ingredient transparency, the specific mechanism and associated safety profile of this product cannot be independently verified.
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.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Water-repellent fabric sprays commonly contain PFAS (perfluorinated compounds); 303 Products has not disclosed whether this formulation includes PFAS. Graded Poor (40/100) in PFAS safety profile, indicating likely presence or undisclosed risk.
Source, ATSDR ↗Inhalation exposure during application
Aerosol spray products release fine mist particles that can be inhaled during application. Respiratory irritation and systemic exposure to coating chemicals (whether PFAS, silicone, or other) occur with improper ventilation or repeated use without protection.
Skin and eye contact irritation
Fabric guard sprays can irritate skin and eyes on direct contact. Proprietary formulations may include surfactants, propellants, or volatile solvents that cause temporary burning or inflammation.
PFAS
If the water-repellent coating contains PFAS, treated textiles will release these compounds during washing and wear, contaminating wastewater and persisting in the environment. This is an indirect hazard to broader human health and ecosystems.
Source, ATSDR ↗Lack of ingredient transparency and verification
Proprietary coating chemistry without published ingredient list, safety data sheet clarity, or third-party certification prevents independent safety assessment. Silent brand stance on PFAS is inconsistent with evolving industry standards and consumer safety expectations.
The full breakdown
The brand's record and disclosure
303 Products has not publicly disclosed the presence or absence of PFAS in this Fabric Guard formulation, nor has the brand published ingredient lists or safety certifications for this product line. The company maintains a proprietary stance on formulation details. No major product recalls or formal safety controversies specific to this product have been publicly documented, but the silence on PFAS content is notable given widespread industry use of fluorinated water repellents and growing consumer and regulatory scrutiny.
How it compares in its category
Fabric guard sprays span a wide spectrum, some brands (e.g., Scotchgard) have faced criticism for historical PFAS use and are moving toward disclosure; others market PFAS-free alternatives based on silicone or wax. 303 Products' refusal to disclose chemistry makes direct comparison difficult. Competitors that openly state PFAS-free status or provide full ingredient lists are more transparent and currently lower-concern choices for the same function.
If you buy it
Apply in well-ventilated outdoor areas or open windows to minimize inhalation of aerosol particles and volatile components. Avoid spraying on areas where children or pets will directly contact treated fabric until dry. Reapplication is typically needed every 6-12 months depending on washing and weather exposure. If PFAS content is critical to your purchasing decision, contact the manufacturer directly for verification before use; absence of disclosure should be treated as a red flag.
