DOTP Passes 3 SGS Tests: Phthalate, EN 71-3, PFAS Free

On June 2, 2026, Shandong Changxing Plastic Additives Co., Ltd. received official SGS-CSTC Qingdao test reports (Work No. TICRSTS260520095013KIYV) for its DOTP plasticizer. As a national-level "Little Giant" specialized and sophisticated enterprise, a Shandong Gazelle Enterprise, and a Shandong Manufacturing Single Product Champion, the company achieved passing results across all three critical environmental compliance tests: phthalates, EN 71-3 element migration, and PFAS total fluorine screening. This article presents the verified test data and explains what the results mean for downstream manufacturers.

Test Summary: Three Reports, Three Passes

Why These Three Tests Matter for Plasticizer Exporters

Dioctyl terephthalate (DOTP) is a leading non-phthalate plasticizer used in PVC flooring, wire and cable, film, artificial leather, and children's toys. However, EU REACH, US CPSIA, and China GB 6675 impose strict limits on phthalate migration, heavy metal leaching, and PFAS content. If the plasticizer itself contains restricted substances, downstream products will fail end-market compliance regardless of manufacturing quality. Third-party plasticizer test reports are therefore the first gate in the export compliance chain.

SGS is a world-leading inspection, verification, testing, and certification company. Its reports are accepted across the EU, US, Japan, South Korea, and Southeast Asia. Choosing SGS-tested DOTP means buyers avoid raw-material re-testing risk and can use the data directly for their own product compliance filings.

Phthalate Testing: 17 Substances, Nearly All Undetectable

Scope and Methodology

The phthalate analysis followed US CPSC standard CPSC-CH-C1001-09.4, using Gas Chromatography-Mass Spectrometry (GC-MS) for qualitative and semi-quantitative screening of 17 phthalate esters. The list covers all substances restricted under EU REACH and US CPSIA: DEHP, DBP, BBP, DINP, DNOP, DIDP, DMP, DEP, DPrP, DIBP, DnPP, DnHP, DCHP, DNP, DIOP, DMEP, and DHpP.

Result Interpretation: DEHP 0.010%, All Others Below MDL

Only DEHP was detected at 0.010% (100 ppm); the remaining 16 substances were below the method detection limit of 0.005%. It is important to note that 0.010% DEHP is far below the EU REACH 0.1% limit for toys and child-care articles, and below US CPSIA safety thresholds for permanently banned substances. For an industrial-grade DOTP plasticizer, this result demonstrates that the terephthalate molecular structure inherently avoids co-formation of phthalate impurities, validating our continuous esterification and multi-stage rectification purification process.

EN 71-3 Element Migration: Zero Detected Across 19 Elements

The Strictest Simulation of Child Exposure

EN 71-3:2019+A2:2024 is the core safety standard under the EU Toy Safety Directive, simulating the ingestion risk of soluble elements through children's mouthing or scraping. Our DOTP was tested under Category III (scraped-off toy materials), using ICP-OES, IC-UV, and LC-ICP-MS to screen for 19 elements: lead, antimony, arsenic, barium, cadmium, chromium III, chromium VI, mercury, selenium, boron, cobalt, manganese, strontium, zinc, copper, aluminum, nickel, tin, and organic tin.

Strategic Significance: Zero Introduction Risk

The report concluded that all 19 elements were non-detectable (ND). This is strategically significant: when DOTP is used in PVC children's toys, food-contact films, or medical tubing, the plasticizer itself does not introduce any regulated heavy metals or hazardous elements. Downstream manufacturers can confidently use our DOTP in high-sensitivity applications without worrying about compliance failures caused by plasticizer migration.

PFAS Fluorine Screening: Below Detection Limits

Preemptive Compliance Amid Global PFAS Restrictions

PFAS (per- and polyfluoroalkyl substances) are under increasing global regulatory scrutiny due to their persistent organic pollutant characteristics. The EU has proposed broad PFAS restrictions, and multiple US states have enacted bans on specific PFAS in consumer goods. SGS performed total fluorine screening using EN 14582:2016 and ion chromatography (IC), with a method detection limit of <20 mg/kg.

Test Result: ND, Well Below Client Requirement

Our DOTP total fluorine screening result was non-detectable (<20 mg/kg), well below the client requirement of 50 mg/kg. While this test screens for total fluorine (which may theoretically include trace inorganic fluoride background), the result confirms the absence of detectable organic fluorinated compounds. For customers targeting markets with emerging PFAS restrictions—such as the EU, North America, and Japan—this is a key preemptive compliance advantage.

The Quality Infrastructure Behind Full SGS Clearance

Passing all three tests at once is not accidental. Shandong Changxing Plastic Additives Co., Ltd. has built an end-to-end quality system covering raw material sourcing, process control, finished-product inspection, and traceability management:

• Integrated management systems: Certified to ISO 9001 (Quality), ISO 14001 (Environment), ISO 45001 (Occupational Health & Safety), and ISO 50001 (Energy);
• Process certification: DOTP production process certified as "internationally advanced," with over 20 national patents;
• Production scale: 300,000 tons annual capacity, with the Jining Wansheng subsidiary adding 150,000 tons of high-standard intelligent production lines;
• Raw material control: Primary feedstocks PTA and octanol sourced from tier-1 suppliers such as Sinopec and CNPC, with batch inbound inspection;
• Online monitoring: DCS automatic control system with real-time key parameter acquisition and out-of-limit automatic alarms.

The SGS test reports are merely external validation of the above quality system. For procurement managers, choosing SGS-tested DOTP means choosing a third-party-backed, reproducible quality assurance capability.

Compliance Value Across Application Scenarios

PVC Flooring and Wall Panels

EU REACH and US EPA set clear limits on phthalates and heavy metals in PVC building materials. Using DOTP that has passed SGS phthalate and EN 71-3 tests helps flooring manufacturers directly satisfy EU EN 14041 and US ASTM F1700 requirements, reducing raw-material re-testing costs.

Wire and Cable Sheathing

EU RoHS 2.0 and China SJ/T 11363 impose strict limits on lead, cadmium, and mercury in cable compounds. With all 19 elements non-detectable in DOTP, cable manufacturers do not need to worry about additional heavy metal compliance risks introduced by the plasticizer.

Children's Toys and Food-Contact Materials

The toy industry is most sensitive to EN 71-3 and phthalate limits. The full SGS clearance of our DOTP provides toy factories with traceable third-party data when facing EU CE marking, US CPSC inspections, and China CCC certification.
