To request a TOFA 180 sample, fill in the sample request form on the product page; in return you receive a traceable sample drawn from a specific production lot, shipped with that lot's certificate of analysis (CoA) and a Turkish Safety Data Sheet (SDS/GBF). When working with a new or second supplier, the real risk is committing to a purchase order before the product has been verified in your own formulation and your own lab; a sample is how you remove that risk before you commit.

How do you request a TOFA 180 sample?

Stating your application (flotation collector, bitumen/asphalt additive intermediate, industrial soap or metal cutting fluid) and your target specification range in the request helps the right lot and the right documentation get prepared. If you are unsure which grade to choose, reviewing the TOFA 185 vs TOFA 180 comparison first and deciding which grade fits your application before requesting a sample saves time.

What should you check in the lab when the sample arrives?

Four measurable values define TOFA 180's grade. Measuring these four in your own lab and comparing them against the CoA results tells you whether the product will behave predictably in your formulation:

  • Acid value (ASTM D1980): must be min. 180 mg KOH/g; it determines the free fatty-acid content and the amount of active matter available on saponification.
  • Iodine value (ASTM D5768): must be min. 150; it indicates the degree of unsaturation and therefore the product's reactivity.
  • Rosin (resin) acid content (ASTM D1240): must not exceed 3%; a higher share can affect color and compatibility in some formulations.
  • Unsaponifiable matter (ASTM D1065): must not exceed 6%; it indicates the share of non-reactive components.

If your lab measurement matches the CoA figures, you have concrete evidence that your TOFA 180 supply will stay consistent from lot to lot.

What documentation should come with the sample?

  • Lot-specific certificate of analysis (CoA): shows the measured acid value, iodine value, rosin acid and unsaponifiable results for the production lot the sample was drawn from.
  • KKDIK registration: TOFA 180 is registered under KKDIK, Türkiye's REACH-equivalent chemical registration system.
  • Turkish Safety Data Sheet (SDS/GBF): provides handling, storage and emergency information in Turkish.

Why do local stock and a documented sample matter more than unit price?

When evaluating a second supplier, the lowest unit price is not the only decision criterion. A supplier that cannot provide a lot-specific CoA or a Turkish SDS carries the risk of an unexpected non-conformance on your production line. Sourcing TOFA 180 from local stock, with KKDIK registration and a CoA for every lot, keeps your formulation consistent from lot to lot and keeps your supply chain auditable.

BİO BAZLI ÜRÜNLERTall Oil Fatty Acids 180 (TOFA)KORKİMYA supplies TOFA 180 as a technical grade in bulk (ISO tank, 20-24 MT net); you can request a sample for lab validation before placing a purchase order.

Safe handling and storage

TOFA 180 is a combustible organic liquid; its vapors and aerosols can irritate the eyes and respiratory tract. Keep the product, including the sample, away from heat, sparks and ignition sources. Always follow the product's current Safety Data Sheet (SDS).
  • Store in closed tanks at 20-40°C; avoid direct sunlight and low-humidity environments.
  • Preferred tank material is carbon steel or stainless steel.
  • Shelf life is 12 months and can be extended to 24 months following a quality-control test.
  • Apply the same handling and storage rules to the sample, even though the quantity is small.
Is the TOFA 180 sample free?

Sample cost and shipping terms can vary by request; confirm the specifics when you submit the sample request. KORKİMYA supports lab validation with a sample and CoA before you commit to a purchase.

What is a typical sample quantity?

No fixed sample quantity is stated for TOFA 180; stating the volume you need for your lab tests in the request helps the right quantity get prepared.

Which value should be tested first?

Acid value (ASTM D1980, min. 180 mg KOH/g) is the first value to check, since it defines the grade and the amount of active matter available on saponification. Then compare the iodine value, rosin acid and unsaponifiable results against the CoA.

Does the sample come with a CoA?

Yes. The sample is drawn from a specific production lot and shipped with that lot's certificate of analysis (CoA), the same practice used for commercial orders.

Can I move straight to a purchase order once the sample is validated?

Yes. If your lab results match the CoA values, you can move to a purchase order with the same specification and documentation (KKDIK registration, Turkish SDS, lot-specific CoA).
