PFAS, sometimes called "forever chemicals," don't break down in nature or in your body. They're used to make products water and stain-resistant. We tested for more than 60 PFAS compounds across two independent international methods and every result came back below detectable limits.

What are they?

PFAS is short for per- and polyfluoroalkyl substances. It's not one chemical but a family of thousands, created to make products water- and stain-resistant. The problem is that they don't break down in the environment or in your body. Instead, they accumulate over time.

What we tested for:

More than 60 individual PFAS compounds across two independent finished-product tests, including PFOA, PFOS, HFPO-DA (GenX), PFHxS, PFNA, PFBS, PFBA, PFPeA, PFHxA, PFHpA, PFDA, PFUnA, PFDoA, PFTrDA, PFTeDA, PFDS, PFHpS, PFOSA, the 4:2, 6:2, 8:2, and 10:2 fluorotelomer alcohols, acrylates, methacrylates, and sulfonates, and the N-methyl and N-ethyl FOSA and FOSE variants.

The standards:

EN 17681-1:2025, the newest European reference method for PFAS in textiles published this year. Plus OEKO-TEX Standard 100 Method 9, the certification protocol behind our Product Class I certification, the strictest tier for products in contact with infant skin.

Phthalates are plasticizers used to soften plastics. They've been linked to hormonal and reproductive effects, which is why they're heavily restricted for products that touch skin. We tested for 21 individual phthalates and every result landed below the strictest thresholds for skin-contact products.

What are they?

Phthalates are chemicals added to plastics to make them more flexible. They're found in products like plastic toys, food packaging, beauty products, and vinyl flooring. The concern is that they can leach out of materials over time and have been linked to endocrine and reproductive effects, particularly in young children. The EU restricts the most-studied phthalates under REACH, and the US restricts several under the Consumer Product Safety Improvement Act.

What we tested for:

21 individual phthalates including DBP, BBP, DEHP, DIBP, DIDP, DINP, DNOP, DPENP, DPP, DCHP, DIPP, DMEP, DHNUP, DIHP, DHP, DIHxP, DHxP, DIOP, DMP, DEP, and DPrP.

The standards:

OEKO-TEX Standard 100 Methods 6 and 6.1, the certification protocol behind our Product Class I certification. Plus RoHS Directive 2011/65/EU, the EU restriction on hazardous substances, and REACH SVHC screening, the European Chemicals Agency’s list of substances of very high concern.

Heavy metals like lead, cadmium, and mercury are toxic even in small amounts. They accumulate in the body over time and can affect the nervous system, kidneys, and developing organs. We tested for 13 heavy metals to ensure every result is well within the strictest safety thresholds for products that touch baby skin.

What are they?

Heavy metals like lead, cadmium, mercury, and arsenic are toxic even in trace amounts. They accumulate in the body over time and can affect the nervous system, kidneys, and developing organs. Some come from industrial processes, while others occur naturally in mineral deposits in raw materials. The strictest international limits for baby products are set by OEKO-TEX Standard 100 Product Class I, the tier we hold.

What we tested for:

13 heavy metals: lead, cadmium, mercury, arsenic, chromium (both total and hexavalent), cobalt, nickel, antimony, copper, manganese, barium, selenium, and zinc.

The standards:

OEKO-TEX Standard 100 Methods 3.1 (extract) and 3.2 (digestion), the certification protocol behind our Product Class I certification. Plus RoHS Directive 2011/65/EU and Chinese GB 28004.1-2021.

100+ pesticide compounds screened across two independent reports. Even trace amounts of agricultural residues can accumulate, so we screen our natural-fiber substrates and plant-derived ingredients and every result comes in below the strictest allowed limits.

What are they?

Pesticides are chemical compounds used in agriculture to kill insects and weeds. Even though our materials go through multiple processing steps, residues can persist on natural fibers and plant extracts. We screen for the major families used globally.

What we tested for:

100+ individual pesticide compounds across two independent reports, covering all major families: organochlorines, organophosphates, pyrethroids, carbamates, herbicides, and triazines.

The standards:

GB/T 18412 series (Chinese national standard for pesticide residues in textiles) and GB/T 39665-2020 (comprehensive pesticide residue standard for plant-derived raw materials).

Bisphenol A (BPA) and its replacements have been linked to endocrine effects. We tested for 19 known and emerging bisphenols to verify each one falls below detectable limits.

What are they?

Bisphenols are used to make plastics hard and clear. BPA is the most famous, but manufacturers have developed replacements like BPS, BPF, BPB, and BPAF that may carry similar endocrine effects. We test for all known and emerging variants, including newer compounds regulators are still studying.

What we tested for:

19 individual bisphenols and bisphenol-related compounds, including BPA, BPS, BPF, BPB, BPAF, BPC, BPE, BPM, BPP, BPZ, BPAP, BPFL, BPBP, BPPH, methyl-bisphenol C, and four additional related compounds (DBMC, DCDPS, DPPO, DCUP).

The standards:

OEKO-TEX Standard 100 Method 25, the certification protocol behind our Product Class I certification. Plus REACH SVHC screening, the European Chemicals Agency’s list of substances of very high concern, and EPA Method 8321B.

Brominated, chlorinated, and phosphate-based flame retardants are banned or restricted in many countries for products that touch skin. We tested for 33 flame retardants across three families.

What are they?

Flame retardants are added to materials to slow or prevent burning. Brominated, chlorinated, and certain phosphate-based variants have been restricted or banned in the EU and other jurisdictions due to health and environmental concerns. Some are persistent and can accumulate in dust, fabrics, and the body over time. Manufacturers still use them in some products, so we test for them specifically.

What we tested for:

33 individual flame retardants across three families:

• 10 polybrominated diphenyl ethers (PBDEs), including DecaBDE
• 11 polybrominated biphenyls (PBBs)
• 12 chlorinated and phosphate-based flame retardants, including HBCDD, TBBPA, TCEP, TCPP, TDCPP, TEPA, TOCP, TXP, TRIS, TMP, TPP, and BBMP

Plus separate testing for short-chain and medium-chain chlorinated paraffins (SCCP and MCCP).

The standards:

OEKO-TEX Standard 100 Methods 8 and 16, the certification protocol behind our Product Class I certification. Plus RoHS Directive 2011/65/EU, the EU restriction on hazardous substances, and REACH SVHC screening.

VOCs (volatile organic compounds) are chemicals that off-gas from materials into the air. Babies breathe faster and are closer to diapers than adults realize. We tested for VOCs in three ways: on the finished diaper and on the materials inside it, to ensure every result is within the strictest safety thresholds.

What are they?

Volatile organic compounds are chemicals that evaporate from materials at room temperature, entering the air you and your baby breathe. This is called off-gassing. Babies have faster respiratory rates and spend hours close to their diaper, making this a meaningful exposure route.

What we tested for:

44 individual VOCs measured on the finished diaper across three families: chlorinated solvents, aromatic hydrocarbons (benzene, toluene, xylene, styrene), and glycol ethers and acetates. Plus a bulk VOC emission test on the finished diaper and a separate 7-day off-gassing test on backsheet materials.

The standards:

GB/T 35613-2017 (bulk VOC emissions from the finished diaper) and GB/T 35613-2024 (7-day off-gassing on materials). Plus OEKO-TEX Standard 100 Method 17, the 44-compound VOC speciation panel behind our Product Class I certification.

The results:

• Total VOC emissions on the finished diaper: 0.0 mg/m³
• 7-day off-gassing test on backsheet: No VOC release detected 
• 44-compound VOC speciation panel on the finished diaper:

Certain azo dyes can break down on contact with skin into aromatic amines linked to cancer. These dyes are banned in the EU and restricted in many other jurisdictions for products that touch skin. We tested for 53 of these breakdown products across two independent reports.

What are they?

Azo dyes are the most common synthetic dyes used in textiles. Most are safe, but a specific subset can break down, when exposed to skin, sweat, or saliva, into aromatic amines that are classified as carcinogenic. The EU bans 22 of these aromatic amines from any skin-contact product. We tested for those 22 and then tested for 31 more.

What we tested for:

53 carcinogenic aromatic amines (arylamines) across two independent reports, including aniline, o-toluidine, p-chloroaniline, benzidine, 4-aminobiphenyl, 2-naphthylamine, 4,4'-oxydianiline, 4,4'-methylenebis(2-chloroaniline), 3,3'-dichlorobenzidine, 2,4-diaminoanisole, and 43 others.

The standards:

EN ISO 14362-1:2017 (REACH Annex XVII, Entry 43, the EU regulation that bans these arylamines in skin-contact products). Plus OEKO-TEX Standard 100 Method 11.1, the certification protocol behind our Product Class I certification.

Many chlorinated compounds are restricted or banned in skin-contact products. We tested for 66 chlorinated substances across three families to ensure every result is within the strictest safety thresholds.

What are they?

Chlorinated compounds are used in bleaching, as solvents, and as processing aids in manufacturing. Many have been restricted or banned by the EU and other regulatory bodies for skin-contact products due to toxicity concerns. A few persist as low-level environmental background contaminants and are nearly impossible to eliminate completely from any modern manufactured material, so the strictest international standards set safety thresholds rather than absolute bans. That is the bar we test against.

What we tested for:

66 chlorinated compounds across three families:

• 19 chlorinated phenols, including pentachlorophenol and other restricted variants
• 33 chlorinated benzenes and toluenes
• 14 chlorinated solvents

The standards:

OEKO-TEX Standard 100 Methods 5, 12, and 17, the certification protocols behind our Product Class I certification. Plus REACH SVHC screening, the European Chemicals Agency’s list of substances of very high concern.

PAHs (polycyclic aromatic hydrocarbons) are combustion byproducts that can contaminate petroleum-based materials. Several are classified as probable human carcinogens. We tested for 25 individual PAHs across two independent reports.

What are they?

PAHs form when organic matter burns incompletely. They can contaminate fossil-fuel-derived materials like some plastics, rubbers, and dyes. Several PAHs, including benzo[a]pyrene, the most studied, are classified as probable human carcinogens by the International Agency for Research on Cancer. The EU restricts 8 PAHs most strictly in skin-contact products under REACH Annex XVII.

What we tested for:

25 individual PAHs across two independent reports, including the 8 PAHs the EU restricts most strictly: benzo[a]pyrene, benzo[e]pyrene, benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[j]fluoranthene, benzo[k]fluoranthene, and dibenz[a,h]anthracene. Plus naphthalene, anthracene, phenanthrene, fluoranthene, pyrene, fluorene, and 11 others.

The standards:

OEKO-TEX Standard 100 Method 13, the certification protocol behind our Product Class I certification. Plus independent GC-MS analysis, the gold-standard analytical method for PAH detection.

Organotin compounds are used as stabilizers in some plastics and have been restricted for skin-contact products. We tested for 18 organotin compounds on the finished diaper and ran additional component-level tests across the supply chain.

What are they?

Organotin compounds are used as heat and light stabilizers in PVC and other plastics, and as biocides in marine coatings. They are known endocrine disruptors. The most studied, tributyltin (TBT), dibutyltin (DBT), and dioctyltin (DOT), are tightly regulated for any product that touches skin. TBT is restricted under the Stockholm Convention; the EU restricts multiple organotins under REACH Annex XVII.

What we tested for:

18 individual organotin compounds on the finished diaper, including trimethyltin (TMT), monobutyltin (MBT), dibutyltin (DBT), tributyltin (TBT), tetrabutyltin (TeBT), monooctyltin (MOT), dioctyltin (DOT), trioctyltin (TOT), tetraoctyltin (TeOT), monophenyltin (MPhT), diphenyltin (DPhT), triphenyltin (TPhT), tricyclohexyltin (TCT), and five additional variants.

The standards:

OEKO-TEX Standard 100 Method 7, the certification protocol behind our Product Class I certification. Plus GB/T 20385.1-2021 (component-level testing across three independent reports) and REACH SVHC screening.

APEOs (alkylphenol ethoxylates) are surfactant residues that can break down into endocrine-disrupting compounds. They're restricted under European REACH regulations for products that touch skin. We tested for 8 alkylphenol and alkylphenol ethoxylate compounds.

What are they?

APEOs are surfactants, cleaning agents, commonly used in textile manufacturing. The concern is that they can break down into alkylphenols, specifically nonylphenol and octylphenol, which act as endocrine disruptors and persist in the environment. The EU restricts both APEOs and their breakdown products under REACH for products that contact human skin. We test for the full family, both the surfactants and the alkylphenols they break down into.

What we tested for:

8 individual alkylphenol and alkylphenol ethoxylate compounds. 

The standards:

OEKO-TEX Standard 100 Method 20, the certification protocol behind our Product Class I certification. Plus GB/T 30133-2022, the Chinese national standard for topsheets in disposable hygiene products, and REACH SVHC screening.

N-nitrosamines are a class of compounds, several of which are classified as probable human carcinogens. We tested for 15 individual nitrosamines under two conditions, both as existing compounds and as precursors that could form them, for 30 total measurements.

What are they?

N-nitrosamines form when certain chemicals react with nitrogen oxides. Several are classified as probable human carcinogens by the International Agency for Research on Cancer, and they've been the subject of major recent regulatory actions on rubber, cosmetics, and food contact materials. The most rigorous testing protocols look for two things: nitrosamines that are already present in a material, and the precursor compounds that could form nitrosamines under conditions like skin contact, heat, or exposure to bodily fluids. We test for both.

What we tested for:

15 individual N-nitrosamines, each measured both as a free compound and as a nitrosatable precursor, for 30 total measurements.

The standards:

OEKO-TEX Standard 100 Method 19, the certification protocol behind our Product Class I certification.

The European Chemicals Agency maintains a list of substances identified as posing the greatest risk to human health and the environment, currently 254 substances. We tested every major component of the diaper against the full list.

What are they?

The European Union's REACH program (Registration, Evaluation, Authorization and Restriction of Chemicals) identifies Substances of Very High Concern: chemicals that pose serious risks to human health or the environment. The list is maintained by the European Chemicals Agency, updated twice yearly, and currently includes 254 substances spanning solvents, processing aids, UV stabilizers, siloxanes, bisphenols, phthalates, heavy metals, PFAS, and emerging chemicals of concern. It is the most comprehensive consolidated list of regulated harmful substances anywhere in the world.

What we tested for:

The entire REACH SVHC list, 247 substances on the current candidate list plus 7 candidates pending designation, tested across five independent reports covering every major component of the diaper, the topsheet nonwoven, structural nonwovens, hot melt adhesives from two suppliers, and core layers.

The standards:

REACH Regulation (EC) No 1907/2006 SVHC Candidate List (January 2025 edition), tested by independent SGS, SOAR, and CTI laboratories.

Poor manufacturing hygiene can introduce bacteria and fungi at any stage of production. We test the most contamination-prone material in the diaper, the adhesives, for six microbial indicators under the strictest Chinese national hygiene standard for single-use sanitary products.

What are they?

Microbiological contamination results from poor hygiene during manufacturing or storage. Adhesives are particularly susceptible because they're applied wet during assembly and can harbor microbial growth if not properly controlled. We test for the most common and problematic bacteria and fungi that could cause infection or skin irritation.

What we tested for:

Six microbial indicators per GB 15979-2024, the Chinese national hygiene standard for single-use sanitary products:

• Coliforms (including E. coli)
• Total aerobic bacterial count
• Total fungal and mold count
• Pseudomonas aeruginosa
• Staphylococcus aureus
• Hemolytic streptococcus

The standards:

GB 15979-2024, the Chinese national hygiene standard for single-use sanitary products. Tested by independent GTTC (Guangzhou Inspection Testing and Certification Group) laboratories.
