Phthalate-Free Explained Glue-Down LVT · REACH Restriction · DINCH · DOTP
Phthalate-free indicates that a glue-down LVT product uses alternative plasticizers rather than the traditional phthalate-based compounds (DEHP, DBP, BBP, DIBP) that are restricted under REACH and other regulations. Because LVT is a PVC-based product, plasticizers are essential to its formulation — the question is which type is used. Phthalate-free products substitute higher-molecular-weight, lower-migration alternatives such as DINCH or DOTP. Reference-only: no product recommendations.
Key regulated phthalates (DEHP, DBP, BBP, DIBP) are restricted to ≤0.1% by weight under REACH in articles sold in the EU. Common alternatives in phthalate-free LVT are DINCH and DOTP. A phthalate-free claim should cover all product layers — verify scope via an HPD or manufacturer test report. The claim is about plasticizer chemistry, not PVC content.
Regulatory Context for Phthalates in LVT
REACH restriction
Under the European Union's REACH regulation (Annex XVII, Entry 51), four high-concern phthalates — DEHP (di(2-ethylhexyl) phthalate), DBP (dibutyl phthalate), BBP (benzyl butyl phthalate), and DIBP (diisobutyl phthalate) — are restricted in articles placed on the EU market to a maximum of 0.1% by weight (1,000 ppm), individually or in combination. Floor coverings are classified as articles under REACH, so this restriction applies directly to LVT sold in Europe and to products certified for EU markets. Products marketed as phthalate-free typically comply with this limit and often go further by eliminating these substances entirely rather than staying just below the threshold.
North American context
In North America, the U.S. CPSIA restricts certain phthalates in children's toys and childcare articles but does not impose the same blanket 0.1% limit on flooring products for general commercial use. However, many commercial specifications for healthcare, K–12 education, and LEED projects voluntarily specify REACH-level phthalate limits for flooring, effectively importing the EU standard into North American project requirements. California's Safer Consumer Products program has also designated certain phthalates as priority chemicals, and some state-level procurement requirements may apply to commercial flooring in public buildings.
Alternative Plasticizers in Phthalate-Free LVT
The most widely used alternative plasticizers in phthalate-free LVT are DINCH (diisononyl cyclohexane-1,2-dicarboxylate, also sold under the trade name Hexamoll DINCH) and DOTP (dioctyl terephthalate, also called DEHT or Eastman 168). Both are high-molecular-weight plasticizers that function similarly to phthalates in PVC processing but have lower hazard classifications. DINCH has been extensively evaluated by the German BfR and European EFSA for food-contact applications and carries low chronic hazard classifications; it is commonly used in healthcare-grade LVT where maximum chemical safety is required. DOTP is also widely used and has received favorable regulatory review. Both alternatives are non-SVHC under current REACH listings. The specific plasticizer type and quantity is identifiable in the product's HPD if one has been prepared.
Spec Sheet Checklist
- Confirm which phthalates are excluded — the claim should specifically cover DEHP, DBP, BBP, and DIBP at minimum.
- Verify whether the phthalate-free claim applies to all product layers or only selected layers (wear layer, backing, etc.).
- Request the HPD or test report to identify the alternative plasticizer type (DINCH, DOTP, or other) used in each layer.
- Confirm the basis for the claim — REACH compliance, third-party laboratory testing, or program certification (e.g., bluesign, Cradle to Cradle).
- Check whether the claim is product-specific or collection-wide — formulations can vary within a manufacturer's line.
FAQ
Is phthalate-free the same as PVC-free? ⌄
No. PVC is the polymer resin; phthalates are plasticizers added to make it flexible. A product can be phthalate-free while still being fully PVC-based — it simply uses alternative plasticizers like DINCH or DOTP instead of restricted phthalate compounds. The two claims address different aspects of a product's chemistry. Phthalate-free does not mean the PVC resin has been eliminated; it means the specific class of plasticizer has been substituted.
Which phthalates are regulated and what are the limits? ⌄
Under REACH, the four restricted phthalates — DEHP, DBP, BBP, and DIBP — are limited to 0.1% by weight (1,000 ppm) in articles sold in the EU, including floor coverings. North American regulations are less comprehensive for flooring, but many commercial project specifications voluntarily adopt the REACH 0.1% threshold as the project requirement. Some manufacturers report phthalate content in parts per million in their HPDs or test reports, allowing direct comparison against applicable limits.
What plasticizers are used instead of phthalates? ⌄
The most common alternatives in phthalate-free LVT are DINCH and DOTP. DINCH (marketed as Hexamoll DINCH) is a cyclohexane-based plasticizer with extensive regulatory review history and low chronic hazard classification, commonly used in healthcare-grade products. DOTP (dioctyl terephthalate) is a terephthalate-based alternative widely used in commercial LVT. Both have lower migration potential than traditional phthalates and are not classified as SVHCs under current REACH listings.
Does a phthalate-free claim apply to all layers of an LVT product? ⌄
Not always, and this is an important detail to verify. Some manufacturers have transitioned all layers of their LVT to phthalate-free plasticizers; others may apply the claim only to the wear layer or the primary contact surface. The backing layer — which is in direct contact with the adhesive and subfloor — often uses a separate formulation. The HPD for the product, if available, identifies the plasticizer used in each layer separately and is the most reliable source for confirming whether the full product is phthalate-free.
