Ernie Ball 3123 Coated Super Slinky Electric Guitar Strings
Unclear coating chemistry; PFAS risk cannot be confirmed for guitar strings.
A proprietary polymer coating extends string life, but Ernie Ball withholds coating details and any PFAS information. Guitar strings are low-contact products with minimal typical PFAS exposure versus cookware or apparel.

What Ernie Ball 3123 Coated Guitar Strings is made of, ingredients and materials
Ernie Ball 3123 strings use a nickel-plated steel core wound with a proprietary polymer coating designed to extend playability life and reduce finger noise. The coating chemistry is proprietary and not publicly disclosed, which means the specific polymer type (polyurethane, polyester, acrylic, or other) cannot be independently verified. Nickel-plated steel is a standard material in electric guitar strings and poses minimal dermal or ingestion risk during normal playing, though nickel sensitivity in players with contact dermatitis is theoretically possible but rare.
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.
Unknown / proprietary coating
A coating is recorded with no disclosed chemistry.
Nickel contact dermatitis
Nickel-plated strings can trigger contact dermatitis in users with nickel sensitivity, though prevalence among musicians is low. Direct skin contact during play is the primary exposure route.
PFAS
The specific polymer coating formulation is not disclosed. Unknown additives (plasticizers, cross-linkers, antimicrobials) in the coating could pose minor inhalation or dermal risk if coating degrades, but no reports of adverse effects exist for this product.
Source, ATSDR ↗What’s reassuring
Coating degradation and particulate shedding
Coated strings are designed to resist wear, and no studies document harmful particulate release during normal playing. If coating flakes with age, small polymer particles may contact skin or be inhaled, but this is not an established hazard class for guitar strings.
Heavy metals
The nickel-plated steel core is not formulated to release lead, cadmium, or other regulated metals during normal use. Nickel plating is a standard guitar string material with no known leaching hazard into skin or saliva during play.

The brand's record and disclosure
Ernie Ball does not publicly disclose the chemical composition of its proprietary string coatings or provide material safety data sheets accessible to consumers. The brand has no known environmental certifications (e.g., ISO 14001) or third-party toxicology assessments for string products. No recalls, safety warnings, or regulatory actions specifically targeting Ernie Ball strings have been documented in public records. The lack of transparency on coating chemistry is typical across the guitar string industry but limits independent hazard verification.
How it compares in its category
Coated strings (Ernie Ball, D'Addario, Elixir) generally carry similar undisclosed coating chemistry risks as this product. Uncoated strings (plain steel or bronze) avoid proprietary polymer exposure but wear faster and require more frequent replacement. Ernie Ball is a market leader with long consumer use history and no documented safety incidents, suggesting a baseline safety profile comparable to or better than lesser-known brands. The coating durability claim (longer lifespan than uncoated) means fewer string replacements, reducing cumulative chemical exposure over time.
If you buy it
Store strings in a cool, dry place away from humidity and saltwater environments, as moisture can degrade the coating and expose the nickel-plated core. Wash hands after playing if you have known nickel sensitivity or dermatitis. Replace strings when they lose intonation stability, show visible rust or coating flaking, or fail to maintain tuning, typically every 1 to 3 months depending on playing frequency. Avoid prolonged contact with skin for users with nickel allergy; otherwise, normal playing poses negligible hazard.
