The full breakdown

What it's made of and why it matters

This brush uses natural hair bristles (likely goat, squirrel, or similar animal hair) set into a wooden handle. Natural bristles carry far lower chemical risk than synthetic alternatives because they skip polymer synthesis, adhesive heavy use, and anti-static coatings. Wood handles are inert when untreated or finished with standard non-toxic sealers. The main exposure is incidental contact with skin during application, making material purity the primary concern.

The brand's record and disclosure

RMS Beauty markets itself as a clean beauty brand focused on natural and minimalist formulations, but published safety disclosures or third-party certifications for tools (as opposed to their cosmetic formulas) are not readily documented in public records. The brand does not appear to have faced major tool-safety recalls or formal complaints. However, their silence on PFAS or material sourcing for brushes suggests limited transparency in that direction, typical of smaller indie beauty brands.

How it compares in its category

Natural hair brushes are considered safer than synthetic nylon or taklon brushes, which can shed microplastics and may retain synthetic coatings or dyes. This product sits in the premium-natural segment, alongside brands like Artis and Wayne Goss, which prioritize hair quality over cost. Wooden handles are standard across this tier and preferable to plastic alternatives that risk BPA or phthalate leaching.

If you buy it

Rinse bristles gently with lukewarm water and mild soap after each use to prevent product buildup and bacterial growth, then air-dry bristle-end-up. Avoid prolonged water exposure on the wooden handle or soaking, which can warp wood and weaken bristle adhesive. Replace the brush if bristles shed excessively, fall out, or become matted. Store in a dry location away from heat to preserve bristle integrity and wood finish.

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.”

Possible

Formaldehyde resins in wood finish

Wooden handles may be sealed with lacquer or varnish containing formaldehyde releasers, though RMS Beauty's natural brand positioning suggests lower likelihood. No specific testing data for this product is on record.

None known

Heavy metals or dyes in natural bristles

Animal hair bristles are not synthetic or chemically dyed and pose minimal risk. Natural bristles are pre-colored by the source animal. No recalls or contamination reports exist for RMS Beauty brushes.

Possible

Bristle shedding and microfiber exposure

Natural hair bristles can shed, especially with frequent wet cleaning or aging. Shed bristles on face carry negligible toxicological risk but may cause minor irritation in sensitive individuals.

Possible

Bacterial or mold growth if not dried properly

Wet bristles stored without adequate air circulation can harbor bacteria or mold, a hygiene rather than chemical hazard. Risk is user-dependent and controlled by maintenance.

None known

Adhesive toxins at bristle-handle junction

Premium natural hair brushes typically use animal-based or non-toxic synthetic adhesives. RMS Beauty's brand ethos suggests avoidance of epoxy or formaldehyde-based binders, but no public material specification is available.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
