Ecosky-3103 is a 100% bio-based rubber process oil made from tall oil derivatives, the forest-derived by-product of kraft paper production. It is REACH-registered for the EU market and falls outside the scope of the EU Deforestation Regulation (EUDR), because its feedstock comes not as a product of forests but as a side stream of existing pulp production. This structure gives tyre and rubber manufacturers a tangible decarbonisation tool without competing with the food chain for resources.

Forest by-product feedstock

Tall oil is a by-product released during kraft (sulphate) pulp production from pine and similar coniferous trees. Crude tall oil (CTO) is separated by distillation into fatty acids (TOFA), rosin and pitch; Ecosky-3103 is likewise made from these tall oil derivatives. In other words, the feedstock comes not from felling trees to extract oil but by valorising an existing pulp/paper process stream. This is the basis of the product's 'waste valorisation' and 'circular' character.

BİO BAZLI ÜRÜNLEREcosky-3103 (Bio-Based Rubber Process Oil)KORKİMYA offers Ecosky-3103 to manufacturers with sustainable-sourcing and carbon targets, with REACH and EUDR documentation support.

Why outside EUDR scope?

The EU Deforestation Regulation (EUDR) requires proof that certain commodities (soy, cattle, palm oil, coffee, cocoa, rubber, wood) are sourced without causing deforestation. Tall oil, the feedstock of Ecosky-3103, is not a primary forest commodity within this scope but a by-product of kraft pulp production. The product is positioned not as a primary forest commodity but as a chemical derived from an existing industrial stream; it is therefore treated as out of EUDR scope.

EUDR scope interpretation depends on the product, supply chain and current legislation. Ecosky-3103's out-of-scope position is based on producer information; for your own compliance assessment, rely on the product's current documentation and your legal advisor.

REACH registration and content safety

Ecosky-3103 is REACH-registered for the EU market and supports regulatory compliance across the supply chain. In terms of content it is free of phthalates and PAHs (polycyclic aromatic hydrocarbons); total sulphur content is max. 2.0%. These properties offer an advantage over high-aromatic petroleum-based oils in both worker safety and the finished product's regulatory profile.

  • REACH-registered (EU market).
  • Outside EUDR scope - tall oil derivative, forest by-product.
  • Biomass that does not enter the food chain - no resource competition with food production.
  • Free of phthalates and PAHs; total sulphur max. 2.0%.

The decarbonisation narrative

Sustainable rubber sourcing is not only a compliance question but also a carbon question. Per the producer declaration, Ecosky-3103 carries a carbon-negative footprint of -1771.1 kg CO2/tonne (ISO 14067); compared with petroleum-based TDAE at about +2900 kg CO2/tonne, the switch delivers a tangible reduction in product carbon footprint (PCF) and Scope 3 reporting. Manufacturers can thus combine a bio-based content claim, an out-of-EUDR-scope and REACH-registered position, and a carbon-negative footprint in a single material decision. For a numerical comparison of the two oils, see the Ecosky-3103 vs TDAE article.

Safe handling

Store Ecosky-3103 in a cool, dry place away from heat sources and direct sunlight, in tightly closed containers. Use chemical-resistant gloves and eye protection to avoid skin and eye contact; avoid ignition sources in hot operations above the flash point and follow the product's current Safety Data Sheet (SDS).
Why is Ecosky-3103 considered outside EUDR scope?

Its feedstock, tall oil, is not one of the primary forest commodities targeted by EUDR but a by-product of kraft pulp production. The product is positioned not as a primary forest commodity but as a chemical derived from an existing industrial stream; it is therefore treated as out of scope.

Is Ecosky-3103 REACH-registered?

Yes, it is REACH-registered for the EU market. It is also free of phthalates and PAHs, and its total sulphur content is max. 2.0%.

Does the tall oil feedstock compete with food production?

No. Tall oil is a forest/pulp by-product that does not enter the food chain, so it creates no land or feedstock competition with food resources.

How does Ecosky-3103 contribute to sustainability reporting?

Per the producer declaration it carries a carbon-negative footprint of -1771.1 kg CO2/tonne and is 100% bio-based (ASTM D6866). Switching from petroleum-based oil shows up as a direct reduction in product carbon footprint and Scope 3 accounting.

Where can I obtain EUDR and REACH documentation?

You can contact KORKİMYA for current REACH- and EUDR-related product documentation and the technical data sheet; base your own compliance assessment on these documents and your legal advisor.
