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.
Fragrance allergens
Murphy's Oil Soap contains fragrance from natural or synthetic fragrance blends to provide its characteristic scent. While plant-derived fragrances are generally mild, undisclosed fragrance components may trigger contact dermatitis or respiratory sensitivity in susceptible individuals, especially with repeated or prolonged skin contact.
Skin irritation from soap concentration
Undiluted or heavily concentrated soap can disrupt the skin's natural pH and lipid barrier, causing irritation, dryness, or eczema flare-ups. Risk is low with proper dilution and glove use, but individuals with compromised skin barriers or atopic dermatitis should exercise caution.
Inhalation of dust and particles during application
Cleaning wood surfaces, especially older or painted finishes, may release dust, lead particles (if wood is old and lead-painted), or mold spores. Murphy's Oil Soap itself poses no inhalation hazard, but the cleaning activity can stir up environmental contaminants unrelated to the product's chemistry.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Plant-based oils used in traditional soap formulations are not known to be significant vectors for cadmium, lead, or mercury contamination. No recalls or reports link Murphy's Oil Soap to heavy metal exposure.
Source, FDA ↗Microbial growth or preservation failures
The soap base and water formulation have inherent preservation properties; no documented cases of mold, bacterial contamination, or product breakdown in Murphy's Oil Soap under normal storage exist on public record.
The full breakdown
What it's made of and why it matters
Murphy's Oil Soap is formulated from plant-based oils (primarily vegetable oil derivatives), soap, and water, with no synthetic surfactants or harsh solvents. This composition avoids the polymer coatings and chemical additives that carry contamination risks in many household cleaners. The soap breaks down readily in the environment and poses minimal systemic toxicity risk from typical skin contact or incidental ingestion during wood-cleaning tasks. Plant-based formulations inherently lack the persistent organic structures that bioaccumulate.
The brand's record and disclosure
Murphy's Oil Soap (owned by Colgate-Palmolive) has marketed this product for over 100 years with a longstanding reputation for simplicity and non-toxicity; it is widely recognized as a gentle cleaner. The brand does not prominently advertise third-party certifications (EWG verification, Green Seal, etc.), but the formula has remained largely unchanged and stable. No major recalls or contamination incidents are on public record for this specific product. The brand's silence on PFAS reflects the product's traditional formulation, which contains no fluorinated compounds.
How it compares in its category
Murphy's Oil Soap is notably simpler than modern multi-surface cleaners, which often contain synthetic fragrances, preservative systems, and antimicrobial additives. Compared to spray cleaners or silicone-based polishes, it avoids volatile organic compounds (VOCs) and siloxane buildup. It ranks low-hazard among wood-care products because it is applied topically and rinsed or buffed off, limiting skin exposure duration. Eco-friendly alternatives like castile soap are chemically similar, making this product representative of the lower-concern segment of its category.
If you buy it
Dilute according to label instructions (typically 1/4 cup per gallon of water for most cleaning tasks) to minimize any skin irritation risk from concentrated soap. Wear gloves if using repeatedly or if you have sensitive skin, as even mild soaps can disrupt skin barrier over prolonged contact. Ventilate adequately if cleaning large wood surfaces indoors, though VOC risk is minimal; the primary concern is inhalation of dust particles displaced during scrubbing. Store in a cool place and avoid freezing; the product is stable indefinitely under normal conditions.
