The label problem
Walk through any natural-goods store and you'll see the same words on every shelf: "natural," "organic," "non-toxic," "clean." None of them mean anything specific. There's no federal standard for "non-toxic" on a household product. "Natural" has no legal definition in personal care. "Organic" on fabric? Also unregulated unless a certification backs it.
Certifications exist to do the thing the label claim won't: spell out what was tested, what was prohibited, and who checked the work. But not every certification covers the same things — and using the wrong one as a shortcut can give you false confidence in categories it doesn't actually govern.
This guide covers the three most credible certifications you'll encounter when shopping for non-toxic home and personal care products: EWG Verified, OEKO-TEX Standard 100, and GOTS. They have different scopes, different methods, and different blind spots. Understanding the difference is the practical skill.
EWG Verified
Who certifies it: The Environmental Working Group (EWG), a U.S. nonprofit that maintains Skin Deep, one of the largest cosmetic ingredient databases in the world.
What it covers: Personal care products and home cleaning products. Shampoo, body wash, lotion, sunscreen, dish soap, laundry detergent — the things that go on skin or into the household environment daily.
What it actually tests:
EWG Verified isn't a lab test in the conventional sense. The certification screens each ingredient against EWG's "Unacceptable" list — more than 1,500 ingredients of concern flagged for reproductive toxicity, carcinogenicity, endocrine disruption, or environmental harm. To pass:
- Every ingredient must appear in the formulation at full disclosure — no "fragrance" catchall, no "proprietary blend" opt-out.
- No ingredient on EWG's Unacceptable list can be present.
- The brand submits formulation documentation to EWG annually, and EWG may send products for third-party verification testing.
- The certification must be renewed each year.
What it doesn't cover: EWG Verified doesn't govern how the product was made, what the packaging is made of, or how the supply chain operates. It also isn't designed for textiles. A cotton T-shirt or a linen sheet cannot earn EWG Verified — that's outside the certification's scope entirely.
How to verify a claim: Search the product on EWG's Skin Deep database or browse EWG's verified product list. Legitimate products display the full ingredient list within Skin Deep. If a brand says "EWG Verified" but the product isn't in the database, the claim is unverifiable.
Best for: Skincare, body care, personal care, and household cleaning products. If you're looking for a reliable ingredient screen on a shampoo or dish soap, EWG Verified is the strongest credential available at retail scale.
OEKO-TEX Standard 100
Who certifies it: One of 17 OEKO-TEX member institutes worldwide (Hohenstein, TESTEX, OETI, and others). Each institute is accredited by OEKO-TEX, the Swiss international association.
What it covers: Textiles and finished goods — fabric, bedding, clothing, towels, mattresses, rugs, stuffed toys. It tests the physical product that will be in your home or on your skin, not just the fiber source.
What "finished product" testing means:
This is the certification's key distinction. OEKO-TEX Standard 100 tests every component of a finished textile — the fiber, dyes, thread, buttons, zippers, and any chemical treatment — for more than 100 harmful substances. Pesticide residues, formaldehyde, heavy metals, azo dyes, pH, color fastness, allergenic dyes, and biocidal finishes all get tested. Passing means the product as you'd actually use it meets the limits.
The four classes set different testing thresholds based on how the item is used:
| Class | What it covers | Strictness |
|---|---|---|
| Class I | Baby products (children up to 36 months), items with direct oral contact | Strictest — babies chew, mouth, and sleep against these items |
| Class II | Items with direct skin contact (underwear, shirts, socks, bedding) | High — persistent skin contact is the assumption |
| Class III | Items without direct skin contact (outer jackets, upholstery) | Moderate — limits set for occasional contact |
| Class IV | Decoration materials (curtains, furniture fabrics, wall coverings) | Lowest — assumes no sustained body contact |
For most households, Class I and Class II are the labels that matter. For baby clothing, crib bedding, and anything a child will chew or sleep against: look for Class I specifically. A product carrying only a Class III certificate on baby pajamas is not the same thing.
What it doesn't cover: OEKO-TEX Standard 100 does not certify organic fiber sourcing. A conventional cotton sheet can earn OEKO-TEX Standard 100 Class I if the finished product passes residue testing. The certification is also not a supply chain audit — it doesn't cover labor conditions or the environmental impact of farming.
How to verify a claim: Every certified product has a certification number printed on its label or packaging. Look it up in OEKO-TEX's verification database at my.oeko-tex.com or via the OEKO-TEX app. The database returns the specific certificate, the product type, and the expiration date. If you can't look it up, the claim isn't verifiable.
Best for: Bedding, towels, clothing, and any finished textile where you want assurance that the finished product has been tested for harmful residues — particularly when GOTS-certified options aren't available in a category.
GOTS — Global Organic Textile Standard
Who certifies it: GOTS-accredited independent certifiers (Control Union, Ecocert, OneCert, and others). GOTS sets the standard; the certifiers conduct on-site audits.
What it covers: Textiles from fiber to finished product. GOTS is the most comprehensive textile certification, governing both what the fiber is made of and every step of the processing chain: spinning, knitting, dyeing, finishing, and manufacturing.
The two tiers:
- "Organic" label (green GOTS logo): ≥95% certified organic natural fiber. The remaining ≤5% must be a non-harmful synthetic.
- "Made with Organic [fiber]" label: ≥70% certified organic natural fiber. The label must name the fiber (e.g., "Made with Organic Cotton").
Both tiers apply the same processing restrictions — the percentage requirement only affects the labeling claim, not the standards for dyeing, finishing, or manufacturing.
What processing coverage means:
A product can be made from 100% certified organic cotton and still be finished with azo dyes, formaldehyde-based wrinkle treatments, or synthetic fragrance. GOTS closes that gap. Substances prohibited in GOTS-certified processing include:
- Azo dyes that cleave to carcinogenic arylamines
- Formaldehyde-based wrinkle-resistance treatments
- Heavy metal-based dyes and mordants
- Chlorine bleaching (only hydrogen peroxide allowed)
- Organotin compounds, phthalates, PFAS
- Nanosilver, triclosan, and other antimicrobial textile treatments
- Synthetic fragrance and allergenic fragrances
Social criteria: GOTS incorporates ILO (International Labour Organization) core labor standards — no child labor, no forced labor, freedom of association, and safe working conditions. Most textile certifications cover chemistry. GOTS covers the people doing the processing too.
How to verify a claim: GOTS maintains a public database at global-standards.org. Search by brand or product name. Because GOTS audits entire production facilities rather than individual products, the database lists the certifier and scope — check that the product's processing steps fall within the certificate's scope.
Best for: Clothing, bedding, towels, baby textiles — anywhere you want both organic fiber sourcing and clean processing under one standard. GOTS is the most credible textile certification available and the hardest to earn.

Decision matrix by product type
Skincare and body care (lotion, shampoo, body wash, deodorant, sunscreen): → Look for EWG Verified. No textile certification applies here. If EWG Verified isn't available, MADE SAFE is a credible alternative (see below). Manually checking Skin Deep ratings is a reasonable fallback.
Household cleaning products (dish soap, laundry detergent, surface cleaners): → EWG Verified is the only major certification that covers cleaning product ingredients systematically.
Baby clothing: → GOTS is the strongest signal. If GOTS isn't available, look for OEKO-TEX Standard 100 Class I — the stricter tier designed for items babies will mouth, wear for hours, and sleep near. A baby garment with only a Class II or Class III certificate is not equivalent. The baby clothes guide covers what to look for beyond certifications in this category.
Adult clothing (underwear, t-shirts, anything worn against skin): → GOTS preferred; OEKO-TEX Class II acceptable when GOTS isn't available. GOTS gives you fiber integrity plus processing; OEKO-TEX Class II ensures the finished product tested clean.
Bedding and towels: → GOTS for organic fiber sourcing — your bedding touches skin for 8 hours a night. OEKO-TEX Class II is acceptable when GOTS isn't available: it ensures the finished product doesn't carry residues even if the fiber isn't organic. The bedding and towels guide covers how to evaluate both certifications in practice.
Crib mattresses: → GOTS for the textile cover, plus GREENGUARD Gold for VOC emissions from the core. The two certifications address different risks — organic fiber in the cover doesn't tell you anything about off-gassing from foam or adhesives inside. See the crib mattress guide for the full breakdown.
Baby and children's toys (fabric, stuffed, plush): → OEKO-TEX Standard 100 Class I at minimum, since children mouth fabric toys. GOTS preferred.
Rugs and home furnishings (curtains, upholstery): → OEKO-TEX Class III or GOTS for items in a child's room. Categories with significant off-gassing potential (rugs, foam upholstery) additionally warrant GREENGUARD Gold or an equivalent low-VOC certification.
Combinations that matter
GOTS and OEKO-TEX Standard 100 are not in competition — they test different things, and a textile can legitimately hold both.
GOTS certifies the supply chain: the fiber was organically grown, the processing was clean, the labor conditions met ILO standards. OEKO-TEX Standard 100 tests the finished product: what's actually in it after all that processing, measured in the product you'll use.
A GOTS-certified sheet that also carries OEKO-TEX Standard 100 Class II gives you both supply-chain assurance and finished-product verification. That combination is the strongest available signal in a textile. Some premium bedding and towel brands hold both for exactly this reason — it's worth looking for in high-contact, high-use categories.
One practical note on scope gaps: GOTS certifies the textile, not auxiliary components. A GOTS-certified pillow cover does not necessarily have a GOTS-certified insert. Read the product listing carefully to see which components the certification actually covers.
A note on MADE SAFE
MADE SAFE (Made with Safe Ingredients) is a U.S. nonprofit certification for products applied to the body or used in the home — personal care, baby products, cleaning products, and some textiles. Its ingredient screen is comparable in rigor to EWG Verified, using a database of known and suspected harmful ingredients vetted by scientists.
Where MADE SAFE appears most often: baby personal care (balms, shampoos, wash), cleaning products from smaller brands, and children's product categories where EWG Verified coverage is sparse. It's not a step down from EWG Verified — both are legitimate independent screens with documented methodology.
