An eco friendly organic sanitary pad is only as credible as the documents behind it. Two report families do most of that work: an in vitro cytotoxicity test on the skin-contact nonwoven material, and a skin sensitization or skin allergy test. They measure different things, on different samples, under different standards. This guide explains, document by document, what each report covers, which product it belongs to, and how a buyer should check it before placing a private-label order.

In Vitro Cytotoxicity Test Report No. SDWH-M201900236-1 (E) for non-woven fabrics used as skin-contact raw material, tested to the ISO 10993-5:2009 method shown in the report.

1. Problem Definition: "Tested" Is Not a Test Report

A cytotoxicity test and a skin allergy test are routinely treated as the same piece of evidence. They are not. A cytotoxicity report evaluates a material in a laboratory cell-culture test. A skin allergy or sensitization report evaluates a defined sample against skin reaction criteria. One can be issued for a roll of nonwoven fabric; the other can be issued for a finished, sealed pad. A buyer who accepts one as proof of the other ends up with a compliance file that cannot support the claim printed on the packaging.

The practical problem shows up in three ways during sourcing of eco friendly organic sanitary pads.

• Wrong sample scope. A material-level report is quoted as if it were a finished-product test, or a report for one pad size is quoted for an entire size range.
• Missing identifiers. A supplier sends a screenshot with a visible logo but no sample name, no standard, no issuing laboratory and no report number — nothing that can be checked.
• Unverifiable claim language. Words such as "hypoallergenic" or "dermatologically tested" are published without naming the document, the sample or the test method that would justify them.

The fix is procedural, not promotional. Before evaluating price, a buyer should be able to answer five questions for every document on the table: what sample was tested, under what standard, by which laboratory, under what report number, and what exactly does that document allow me to say.

2. Industry Background: Why Report Numbers Became a Purchasing Requirement

The organic and biodegradable segment has moved from a niche shelf position to a documented procurement category. TechSci Research projects the global organic sanitary napkins market at USD 3.02 billion in 2025, rising to USD 4.51 billion by 2031. Mark & Spark Solutions estimates the biodegradable sanitary napkins segment will grow at a compound annual growth rate of 20.1% between 2024 and 2030, reaching USD 8.54 billion by 2030. Dataintelo reports that Asia Pacific held a 38.6% revenue share of the biodegradable sanitary napkins market in 2025.

Trade mechanics reinforce the same direction. Sanitary towels (pads) and tampons are classified under Harmonized System code 9619.00, as listed by trade-data provider Descartes Datamyne, which means cross-border shipments are described, declared and inspected using a shared product language. On the regulatory side, compliance summaries note that the FDA Quality Management System Regulation (QMSR) under 21 CFR Part 820, which incorporates ISO 13485:2016, took effect on 2 February 2026 for menstrual products — adding another reason why suppliers are asked for controlled documents rather than product adjectives.

Growth in a regulated category produces one predictable outcome: buyers stop comparing suppliers on wording and start comparing them on evidence. For an organic pad project, that usually means material-level biocompatibility reports, finished-product hygiene and performance reports, material-origin certificates, and market-entry documents.

3. Detailed Solution: The Two Test Paths Behind Organic Sanitary Pads

Four document families sit behind a typical eco friendly organic sanitary pad file. Each answers a different question, and each has a defined limit.

Path A — In vitro cytotoxicity on the skin-contact nonwoven (ISO 10993-5:2009)

An in vitro cytotoxicity test screens a material for cytotoxic response in a controlled laboratory setting. For feminine hygiene products, the relevant material is the nonwoven fabric that touches skin.

Report No. SDWH-M201900236-1 (E) is an In Vitro Cytotoxicity Test Report for Non-woven fabrics, issued by the Sanitation & Environment Technology Institute, Soochow University, using the ISO 10993-5:2009 test method shown in the report. Its scope is non-woven fabrics used as skin-contact raw material for feminine hygiene products. Organic bamboo sanitary pads fall inside this material coverage, because the pad's skin-contact layer is a nonwoven fabric.

What this means for a buyer: the fabric that sits against skin has been screened in a laboratory test with a named method, a named issuing institution and a traceable report number — rather than being described only as soft, natural or skin-friendly in a catalogue.

Path B — Skin sensitization and skin irritation on the same nonwoven

Two companion reports extend the material-level review. Report No. SDWH-M201900236-2 (E) is a Skin Sensitization Test Report for Non-woven fabrics, and Report No. SDWH-M201900236-3 (E) is a Skin Irritation Test Report for Non-woven fabrics. Both were issued by the Sanitation & Environment Technology Institute, Soochow University, under the ISO 10993-10:2010 test method shown in the reports, with the same scope: non-woven fabrics used as skin-contact raw material for feminine hygiene products.

Sensitization testing addresses the risk of a delayed reaction after repeated contact; irritation testing addresses local skin reaction. Read together with the cytotoxicity report, the three documents form a material-level biocompatibility set for the skin-contact fabric — and they share one limitation: they describe the material, not the finished pad.

Skin Sensitization Test Report No. SDWH-M201900236-2 (E), issued by the Sanitation & Environment Technology Institute, Soochow University, for non-woven skin-contact fabric.

Path C — Finished-product skin allergy testing under GB 15979-2024

The document buyers most often mean when they ask for "a skin allergy test" is a finished-product report. Report No. 252004820 is a fabric skin allergy test report for Amyas disposable sanitary pads (sterilized grade), size 245MM, issued by Guangzhou Inspection Testing and Certification Group Co., Ltd. (GTTC) on 30 January 2026, under GB 15979-2024, the Chinese hygienic requirements standard for disposable sanitary products.

The distinction is not administrative. The sample identity line on this report names a product, a grade and a size. A material report names a fabric. If your specification changes the topsheet material, the pad size or the production line, the finished-product evidence has to be re-confirmed for the new build — a material certificate cannot be stretched to cover a new product configuration.

Report No. 252004820, issued by GTTC on 30 January 2026 for Amyas disposable sanitary pads (sterilized grade), size 245MM, under GB 15979-2024.

Path D — Finished-pad performance and hygiene evidence

Product-level evidence sits alongside biocompatibility evidence. Report No. 260059776 covers Lilimolone Ultra-Thin Bamboo Sanitary Pads 245mm, tested for physical-chemical and hygiene safety for sanitary pads. It was issued by GTTC on 1 April 2026 under GB/T 8939-2018, the standard for sanitary absorbent pads and panty liners, together with GB 15979-2024. This is the report a retail buyer usually wants to see when confirming that a specific finished pad meets a defined hygiene and performance baseline.

4. Step-by-Step: How to Read a Cytotoxicity or Skin Allergy Report

The following sequence works for any test report presented during an eco friendly organic sanitary pad project.

• Step 1 — Classify the document. Is it material-level biocompatibility (ISO 10993 series), finished-product hygiene and performance (GB/T 8939-2018, GB 15979-2024), antimicrobial activity, or material origin (GOTS, OCS, FSC)? The class determines what the document can support.
• Step 2 — Read the sample identity line first. Compare exact wording: non-woven fabrics as skin-contact raw material, versus Amyas disposable sanitary pads (sterilized grade), size 245MM, versus Lilimolone Ultra-Thin Bamboo Sanitary Pads 245mm. The sample line is the boundary of the claim.
• Step 3 — Confirm the standard and test method. Check that the number on the report matches the standard you are relying on: ISO 10993-5:2009, ISO 10993-10:2010, GB 15979-2024, GB/T 8939-2018 or GB/T 20944.3-2008.
• Step 4 — Identify the issuing body and its field. A university institute, a testing and certification group and a microbiology centre each cover different test types. Match the institution to the test.
• Step 5 — Verify the report number and any verification code. Ask the supplier to quote the number in writing and match it against your copy. Where a verification code exists — for example LU9T6NKP on Report No. 2025FM19954R01E — use it.
• Step 6 — Check dates honestly. Some documents carry a clear issue date: Report No. 252004820 on 30 January 2026, Report No. 260059776 on 1 April 2026, Report No. 2025FM19954R01E on 19 November 2025, Report No. 210285558 on 23 September 2021. If a copy shows no visible issue date, request the controlled version rather than assuming the report is current.
• Step 7 — Match the report to the pad you are ordering. A 245mm finished-product report belongs to a 245mm product. Material coverage applies to the material, not to every size, thickness or absorbency level built from it.
• Stey 8 — Map the evidence to your market file. EU-oriented files may reference the ISO 10993 series through a Declaration of Conformity; GB-based reports support product-level hygiene evidence; Halal, FSC, GOTS and OCS answer separate questions about market acceptance, pulp traceability and organic material scope.
• Step 9 — Write the claim only after the document is named. If you cannot complete the sentence "this claim is supported by report number ___, on sample ___, under standard ___, issued by ___", do not publish the claim.

5. Use Cases: Who Actually Reads These Documents

Private-label brand launching an eco-positioned line. The brand needs two layers of evidence: material-level biocompatibility for the skin-contact fabric, and finished-product hygiene and performance data for each size that goes on shelf. Bamboo fiber and organic cotton positions usually add material-origin certificates so the sustainability wording is anchored to a document.

Pharmacy or retail distributor running supplier due diligence. Two quotations for similar organic pads are separated fastest by one question: can you send the report number, the sample scope and the issuing laboratory today? Suppliers who can answer move into the shortlist; suppliers who answer with adjectives do not.

OEM/ODM buyer developing a custom specification. Customization changes the inputs. A supplier offering OEM, ODM, Private Label and customized sanitary pad development and supply-chain services can adjust pad length, shape, thickness, absorbency, wings, organic cotton topsheet, fluff-pulp absorbent core, SAP dosage, plant-based backsheet, individual wrapper, pack count, artwork, logo and language version — and each change should be reflected in a re-confirmed sample and document set.

Export team assembling a market file. A complete file typically combines a Declaration of Conformity, an authorized representative agreement, Halal documentation, FSC chain-of-custody evidence, GOTS or OCS material scope certificates and product test reports. Each document answers one question; none substitutes for another.

E-commerce seller writing product claims. Marketplace listings are where unsupported skin claims cause the most damage. Anchoring descriptions to named reports is the cheapest form of risk control available.

6. Comparison Table: Which Report Proves What

Read the table as a boundary map. Material reports protect the fabric decision; finished-product reports protect the shelf decision; antimicrobial reports support surface-layer wording only; origin certificates protect the sustainability wording. A buyer who needs all four asks for all four — not for one document described in four different ways.

8. Conclusion: Evidence Discipline Is the Real Differentiator

Eco friendly organic sanitary pads are sold in a market where the sustainability and skin-comfort claims are increasingly easy to make and increasingly easy to challenge. The documents that survive scrutiny are narrow by design. Report No. SDWH-M201900236-1 (E) speaks for a nonwoven fabric under ISO 10993-5:2009. Report No. SDWH-M201900236-2 (E) and Report No. SDWH-M201900236-3 (E) speak for the same fabric under ISO 10993-10:2010. Report No. 252004820 speaks for Amyas disposable sanitary pads (sterilized grade) at 245MM under GB 15979-2024. Report No. 260059776 speaks for Lilimolone Ultra-Thin Bamboo Sanitary Pads 245mm under GB/T 8939-2018 and GB 15979-2024. Each one is limited, and that limitation is exactly what makes it usable.

For buyers at the evaluation and execution stage, the sequence is straightforward: decide which report class your claim needs, ask for the report number and sample scope in writing, check the standard and issuing laboratory, confirm the sample matches the product you are ordering, and only then move to sampling, MOQ and lead-time discussion. Suppliers who can answer those questions quickly are, in practice, the ones who can also run a repeat order on the same specification.
