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.
Skin sensitization and irritation from fragrance or soap components
While mineral oil and soap are low-irritancy, prolonged skin contact or use in individuals with eczema or fragrance sensitivity may cause mild irritation. No documented allergic reactions to the formulation are on record, but fragrance is present in some formulations and should be rinsed off skin promptly.
Bacterial or mold growth in the product or on treated surfaces
Water content in the formulation can support microbial growth if the sealed bottle is contaminated or stored improperly. On wood surfaces, residual moisture from diluted application may promote mold if ventilation is poor; always allow surfaces to dry fully and ensure airflow.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Volatile organic compounds (VOCs) and off-gassing
Mineral oil-based formulation has no documented volatile components. Water-based delivery and soap-based emulsification mean no aromatic or aliphatic solvent off-gassing is expected during or after application.
Formaldehyde / VOCs
Standard Murphy Oil Soap formulations do not contain formaldehyde resins, urea-formaldehyde, or formaldehyde-releasing biocides. The product relies on its oil and soap chemistry for preservation, not aldehyde compounds.
Source, ATSDR ↗Heavy metals
Mineral oil is a refined petroleum fraction with no inherent heavy metal load. The product contains no colored pigments or dyes that would introduce lead, cadmium, or antimony contamination.

What it's made of and why it matters
Murphy Oil Soap is formulated from mineral oil, soap (saponified oils), and water. Mineral oil is a highly refined petroleum derivative with no volatilization hazard at room temperature, making off-gassing a non-concern for this product class. The soap component acts as an emulsifier to allow oil and water to mix, a standard food-safe surfactant approach. No aromatic solvents, aldehydes, or harsh organics are present in the standard formulation.
The brand's record and disclosure
Murphy Oil Soap (owned by Colgate-Palmolive) has maintained a stable, minimalist ingredient list for decades with no major safety recalls tied to the cleaner itself. The brand does not publish detailed safety certifications or disclose PFAS testing status, though the product's simple mineral oil base makes PFAS presence unlikely. No established controversies regarding toxic residues or off-gassing exist in public health databases.
How it compares in its category
This product sits in the lower-volatility segment of wood cleaners. It avoids the solvent-heavy profiles of some commercial wood polishes (which may contain petroleum distillates or phenolic compounds) and the potential formaldehyde off-gassing of some varnish-based alternatives. As a simple cleanser rather than a sealant or stain, it poses fewer long-term indoor air quality risks than furniture refinishing products.
If you buy it
Apply diluted (as directed on label) to wood surfaces with minimal pooling to avoid swelling or water damage to veneers or joints. Ensure good ventilation during application, though fume risk is minimal. Do not use on unsealed or water-sensitive wood finishes. Store in a cool place away from heat; no special containment needed. Replace if the product separates significantly or develops mold (indicates water contamination), though shelf life is typically 2-3 years unopened.
