Fatty Acids from Vegetable Oils

Slight darkening of oleic acid is a natural oxidation process caused by exposure to air and light, and it does not affect chemical properties. The iodine color scale may shift from 3 to 5 mg I₂/100 cm³ over the shelf life, which remains within acceptable limits. To minimize darkening, we recommend storing the product in sealed containers in a dark room at +5…+25°C. If you require consistently light-colored acid for cosmetic formulations, we supply a refined grade with antioxidant - please consult your manager.

Iodine value is a critical parameter, and we test it for every batch. Before shipment, we send you a copy of the quality certificate with actual test results - you approve the batch before payment. If the iodine value falls outside your required range, we’ll select another grade (A or C). We offer three grades of oleic acid, enabling us to meet the requirements of any production process.

Fatty acid prices depend on global vegetable oil market rates, exchange rates, and logistics costs - all of which fluctuate monthly. Annual price fixation is possible under a contract with monthly volume selection and 100% prepayment for the chosen month. Alternatively, we offer a long-term contract with a transparent pricing formula: base price + indexation to vegetable oil market indices. This protects you from sudden price spikes.

Every drum and IBC container undergoes leak-tightness inspection before dispatch. During transport, we use wooden bracing and stretch film. Upon receipt, you must inspect packaging integrity in the driver’s presence. If damage is found, we prepare a report with photo documentation and ship a replacement at our expense within 3 business days.

For trial purposes, we supply as little as 20 kg in special containers (5-10-20 L jerrycans) at the standard product price. This volume is sufficient for laboratory and pilot-scale trials. When moving to full-scale production, the minimum order is 200 kg (one drum).
