What 303 Products Fabric Guard Trigger Sprayer is made of, ingredients and materials
303 Fabric Guard is a fabric coating spray applied to textiles to repel water and stains. The brand does not publicly disclose the active repellent chemistry, treatment formulation, or whether it contains fluorinated compounds (PFAS) or silicone-based alternatives. Without transparent ingredient disclosure, it is impossible to assess what solvents, binders, or processing agents are present in the aerosol or trigger liquid.
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.
Volatile organic compounds (VOCs) from solvent and propellant
Trigger spray aerosol products typically contain organic solvents and liquefied gas propellants; inhalation exposure is foreseeable during application. No VOC profile or propellant type is disclosed by the brand.
Respiratory or skin irritation from undisclosed active ingredients
Water-repellent coatings often contain surfactants, siloxanes, or fluorochemicals that can irritate mucous membranes. Without ingredient transparency, irritation risk cannot be quantified or ruled out.
Skin or eye contact injury from spray mist
Fabric guard sprays in trigger format carry typical aerosol hazards; eye contact with fine mist can cause irritation. The brand provides minimal guidance on protective measures.
Contamination of food contact surfaces or dishware
If spray is applied near kitchen linens, dish towels, or aprons without containment, residue may transfer to food-contact items. No on-label guidance addresses this transfer risk.
Environmental persistence and bioaccumulation from undisclosed fluorochemicals
The poor PFAS grade (40/100) reflects likely fluorochemical content; such compounds persist in water systems and wildlife. Brand silence on treatment chemistry means no commitment to phasing out persistent chemicals.
The full breakdown
The brand's record and disclosure
303 Products has not published ingredient lists, safety data sheets, or statements about PFAS use in this product line. The brand has not sought third-party certifications (such as Bluesign or STANDARD 100 by OEKO-TEX) that would validate reduced hazard chemistry. Silence on a water-repellent product's composition is a red flag, as fluorochemicals or other persistent treatments are common in such formulations.
How it compares in its category
Fabric guard sprays range widely in transparency, some brands (e.g., Grangers, Nikwax) publish ingredient disclosure and offer PFAS-free alternatives; others are silent. 303's lack of communication puts it below competitors who certify their formulations. Silicone-based or plant-oil coatings exist as lower-concern alternatives, but 303 does not market these distinctions.
If you buy it
Apply in a well-ventilated area away from skin and eyes; the aerosol propellant and solvent base carry inhalation risk if used indoors. Do not allow spray mist to contact food, utensils, or food-contact surfaces. Store away from heat and children. Test on an inconspicuous corner first, as trigger sprays may darken or stain some fabrics. Request a safety data sheet from the retailer or manufacturer before purchase if you have respiratory sensitivity.
