Butter Gloss NYX
Lower PFAS concern for typical lip gloss formulation.
NYX Butter Gloss is a standard cosmetic lip product with no known PFAS-intensive ingredients like waterproofing or Teflon-family coating. No public PFAS disclosures from the brand, but ingredients appear routine for this category.

The full breakdown
What it's made of and why it matters
Butter Gloss NYX is formulated primarily from oils, waxes, and pigments typical of modern lip glosses. The oil base (likely mineral oil, castor oil, or synthetic esters) provides moisture and shine without the rigid coating concerns of traditional lacquers. Pigments and mica give color and shimmer; these are mineral-derived or synthetic colorants, not organic dyes prone to azo breakdown. The waxy binder holds everything together at room temperature and in the mouth, where it's designed to stay.
The brand's record and disclosure
NYX (owned by L'Oreal) does not publicly disclose detailed ingredient sourcing, allergen testing, or heavy-metal screening specifically for Butter Gloss. The brand maintains general cosmetic safety compliance under FDA and EU rules but has not published third-party safety certifications for this line. No product recalls or established safety incidents are on record for Butter Gloss NYX. L'Oreal as a parent company has faced occasional scrutiny over formaldehyde preservatives in other lines, but not substantiated for this product.
How it compares in its category
Butter Gloss sits squarely in mainstream lip gloss safety, neither premium nor budget-tier. Compared to glitter-heavy glosses (which may trap microplastics), oil-wax formulations like this one present fewer mechanical hazards. Compared to extremely matte liquid lipsticks (which often contain volatile solvents and film-formers), gloss is inherently safer for incidental ingestion. It aligns with typical mass-market cosmetic toxicology expectations.
If you buy it
Apply a thin layer; lip gloss is meant for topical contact, not ingestion, so keep it away from children under 3. Store in a cool place to prevent oils from separating or wax from softening excessively. Replace every 1-2 years or if it develops a strong chemical smell, changes color, or separates. Patch test if you have a known fragrance or mica sensitivity, as some formulations contain fragrance oils that may irritate sensitive mucous membranes.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Fragrance allergens
NYX Butter Gloss formulations often include fragrance oils for scent and flavor. Individual sensitivities to fragrance compounds can cause lip irritation or contact dermatitis; full fragrance ingredient disclosure is typically absent from labels.
Heavy metals in pigments (lead, cadmium, chromium)
Mica and synthetic iron oxides used in cosmetic-grade lip gloss are regulated by FDA for lead and cadmium limits. No recalls or test failures are documented for NYX Butter Gloss; however, third-party testing data is not publicly available for independent verification.
Talc or talc-adjacent contaminants
Butter Gloss is oil-based and does not list talc as a standard ingredient. If any mineral powders (mica, titanium dioxide) are used, they are not typically associated with asbestos cross-contamination in cosmetic formulations, but no independent assay has been published.
1,4-dioxane in emulsifiers or preservatives
Oil-wax glosses require fewer chemical preservatives than water-based products, lowering dioxane risk. However, if the formulation uses ethoxylated emulsifiers or certain preservative systems, trace dioxane may be present as a processing contaminant; NYX does not disclose preservative type.
Microplastic shedding or ingredient contamination
Butter Gloss is not formulated with intentional microbeads. The mica and pigments are larger mineral particles unlikely to shed as microplastics during normal use. Risk is minimal compared to gel or chunky glitter glosses.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 75% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
