Cariloha Retreat 4-Piece Oasis Green Split King Sheet Set
Lower PFAS concern for pure bamboo rayon sheets, but brand makes no explicit disclosure.
Cariloha Retreat sheets are made from bamboo viscose rayon, a cellulose fiber without inherent PFAS chemistry. The brand does not market PFAS-free credentials or provide transparency about dye/finish treatments.

The full breakdown
What it's made of and why it matters
These sheets are rayon produced from bamboo viscose, a regenerated cellulose fiber. The viscose process itself uses sodium hydroxide and carbon disulfide as solvents, but industrial mills recover most of these chemicals; finished rayon fiber contains minimal residual solvent. The advertised 'stain-resistant' claim on this specific product is the main concern: Cariloha does not disclose the stain-resist chemistry, which is typically applied as a post-production coating and may involve PFAS compounds (already graded separately) or other functional finishes.
The brand's record and disclosure
Cariloha does not publish detailed chemical disclosures, safety certifications (such as OEKO-TEX or GOTS), or independent testing results for this product line on public record. The brand markets sustainability and comfort but remains silent on treatment chemicals and PFAS stance. No major recalls or regulatory actions against Cariloha sheets are documented in public sources. This lack of transparency is atypical for premium bedding brands and limits independent verification of stain-resist additive safety.
How it compares in its category
Untreated bamboo viscose sheets are chemically safer than many synthetic blends (polyester-cotton) and far safer than sheets with heavy flame-retardant coatings. However, competing brands like Bali Bamboo and Ettitude explicitly disclose their treatment chemicals or pursue third-party certifications; Cariloha's marketing-focused approach without such transparency is a relative weakness. The stain-resistant feature adds convenience but introduces undisclosed chemistry absent from basic viscose alternatives.
If you buy it
Wash before first use to reduce any residual finish or solvent traces. Bamboo viscose is delicate; use cold or warm water (not hot) and avoid high dryer heat, which can degrade the fiber and potentially concentrate any surface coatings. Line-dry or low heat extends sheet life and minimizes thermal release of finishes. Replace when elasticity visibly declines, typically after 2-3 years of regular use; worn sheets may shed microfibers more readily.
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.”
Undisclosed stain-resist coating chemistry
Cariloha does not publicly identify the active agent in the stain-resistant treatment. Typical options include PFAS (fluorochemicals), silicones, or acrylates; without disclosure, the specific hazard cannot be ruled out, though PFAS risk is assessed separately at 75/100.
Formaldehyde or formaldehyde-releasing resins in finishes
No public record of formaldehyde content or release testing for this product. Bamboo viscose base fiber itself does not require formaldehyde; any residual formaldehyde would stem from dye-fixing or finish resins, which Cariloha has not disclosed.
Residual viscose process solvents (sodium hydroxide, carbon disulfide)
Modern viscose mills are designed to recover solvents; finished rayon fiber typically contains minimal residue. No recalls or testing reports implicate Cariloha sheets for solvent contamination, and cold pre-washing further reduces any trace levels.
Microplastic shedding from degraded coatings
If the stain-resist coating is polymer-based (acrylic, urethane, or Teflon-family coating), mechanical wear and heat exposure may cause flaking or fiber breakage. High-temperature drying or aggressive washing could accelerate this process, though no specific data for this brand exists.
Azo dyes in the 'Oasis Green' colorant
Azo dyes can release hazardous amines under certain conditions; however, no regulatory action or testing report documents this issue in Cariloha products. The brand does not publish dye sourcing or safety certification.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
