What 303 Protectant is made of, ingredients and materials
303 Protectant is a spray-applied UV and water-repellent coating marketed for automotive, marine, and fabric surfaces. The manufacturer does not publicly disclose the specific polymer chemistry, active ingredients, or carrier solvents, only describing it as a protective formula. Water-repellent treatments in this category typically rely on silicone-based or fluorocarbon-based compounds; the opacity around 303's formulation makes independent hazard assessment difficult. The product is aerosolized, meaning inhalation exposure is a primary route of concern.
What’s concerning
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Volatile organic compounds (VOCs) from spray propellant and carriers
Aerosolized protectant sprays typically contain solvent carriers and propellants; inhalation during application is foreseeable, especially in enclosed spaces. 303 does not disclose VOC content or specific solvents, so exposure risk cannot be quantified but should be assumed.
Skin and eye irritation from direct contact
Water-repellent sprays commonly cause mild irritation if applied directly to skin or eyes. 303 Protectant labeling warns against such contact, and adverse event rates appear low in typical use, but irritation remains a foreseeable hazard.
Respiratory sensitization or irritation from repeated aerosol exposure
Chronic or repeated inhalation of spray coatings can trigger respiratory irritation in sensitive individuals. No specific allergic reactions or asthma-trigger reports are documented for 303 Protectant, but the risk is consistent with the product class and opaque formulation.
Incomplete biodegradability of polymer film residue
Water-repellent polymers applied to fabrics or outdoor surfaces may persist in soil and waterways. 303 does not disclose polymer biodegradability or environmental fate data, making long-term ecological impact unclear.
Undisclosed chemical composition and potential unreported hazards
The lack of published full ingredient lists or PFAS testing creates a residual uncertainty hazard. Consumers cannot independently verify claims or assess personal sensitivity to unstated compounds; this is a transparency failure, not a confirmed chemical risk, but a material concern.
How is this PFAS grade calculated?
The brand's record and disclosure
303 Products (maker of 303 Protectant) is a subsidiary of Clorox and has not published detailed safety data sheets, ingredient breakdowns, or PFAS testing results on their consumer-facing website. The brand has not made public commitments to PFAS phaseout or transparency initiatives common in the personal care and household products sector. While Clorox-owned brands have faced scrutiny over chemical transparency, 303 Protectant itself has no documented recalls or formal safety violations on public record for non-PFAS hazards.
How it compares in its category
303 Protectant is a mainstream, premium-positioned product in the UV/water-repellent coating spray category. Competitors range from silicone-based sprays (less PFAS risk but sometimes less durable) to ceramic coatings (more durable, variable PFAS status). Many alternatives similarly lack full transparency; however, some brands now offer PFAS-free or fluorine-free UV protectants. 303's market share and long history suggest it is well-tolerated in normal use, but it does not stand out for chemical transparency or verified PFAS avoidance.
If you buy it
Use 303 Protectant outdoors or in well-ventilated spaces to minimize inhalation of spray aerosol and any volatile organic compounds. Apply in thin, even coats; overuse does not improve protection and increases exposure. Test on a small, inconspicuous area first, especially on fabrics or unsealed surfaces, to check for darkening or staining. Reapply according to product directions (typically every 3-6 months for automotive use) and store in a cool, dry place away from heat or flame.
