Agnique ME 18 RD-F is a naturally derived C18 rapeseed oil methyl ester (methyl canolate) produced by BASF (formerly Cognis), used as a high flash point solvent, carrier oil, and adjuvant base for emulsifiable concentrate, oil dispersion, and tank-mix adjuvant formulations in crop protection applications.
Agnique ME 18 RD-F is produced by the transesterification of rapeseed (canola) oil with methanol, yielding a mixture of C16–C18 and C18-unsaturated fatty acid methyl esters dominated by methyl oleate (C18:1), methyl linoleate (C18:2), and methyl linolenate (C18:3), with smaller proportions of methyl palmitate (C16:0) and methyl stearate (C18:0).
Agnique ME 18 RD-F is a preferred oil adjuvant and carrier solvent in crop protection formulations due to its high flash point greater than 300°C, excellent solvency for hydrophobic active ingredients, low phytotoxicity, ready biodegradability, and renewable bio-based origin from rapeseed (canola) oil.

Benefits or Advantages of Agnique ME 18 RD-F:
Agnique ME 18 RD-F has an exceptionally high flash point greater than 300°C, making it inherently safe from a fire hazard perspective during manufacture, storage, and transport, and enabling formulations that comply with regulatory requirements for high flash point solvents.
Agnique ME 18 RD-F is derived from renewable rapeseed (canola) oil, providing a bio-based carbon profile, contributing to lower lifecycle greenhouse gas emissions, and supporting formulators in developing more sustainable agrochemical products.
Agnique ME 18 RD-F is readily biodegradable, consistent with the established biodegradability of rapeseed oil methyl ester under OECD 301 test conditions, making it an environmentally preferred solvent in crop protection and industrial applications.
Agnique ME 18 RD-F significantly enhances the foliar uptake and efficacy of systemic post-emergence herbicides, functioning as an activating adjuvant that improves weed control ratings compared to formulations without a methylated oil component.
Agnique ME 18 RD-F has low phytotoxicity to most economically important crops when applied at recommended rates, enabling its use in selective herbicide programs without unacceptable crop damage.
Agnique ME 18 RD-F has a pour point below -10°C and a cloud point of approximately -12°C, ensuring it remains liquid and pourable under typical cold-weather conditions encountered in temperate European and North American agricultural regions.
Features of Agnique ME 18 RD-F:
Agnique ME 18 RD-F is a yellow to amber clear liquid at 25°C with a mild fatty characteristic odor, a viscosity below 50 mPa·s at 25°C, a density of approximately 0.88 g/cm³, and a saponification value of approximately 184 mg KOH/g.
Agnique ME 18 RD-F has a pour point below -10°C, a cloud point of approximately -12°C, a flash point greater than 300°C (closed cup), and a vapor pressure of approximately 0.03 hPa at 20°C, reflecting its low volatility and high thermal stability.
Agnique ME 18 RD-F is insoluble in water but miscible with most organic solvents, fatty alcohols, vegetable oils, and mineral oils, and is compatible with a wide range of nonionic, anionic, and cationic surfactants used in crop protection formulation.
Agnique ME 18 RD-F does not foam excessively, has low viscosity facilitating easy pumping and mixing in formulation manufacturing, and does not solidify at typical storage temperatures encountered in European climate zones.
Chemical Properties of Agnique ME 18 RD-F:
Agnique ME 18 RD-F (CAS 67762-38-3) is classified as fatty acids, C16-18 and C18-unsaturated, methyl esters, consisting primarily of methyl oleate (C18:1, ~55–65%), methyl linoleate (C18:2, ~18–25%), methyl linolenate (C18:3, ~8–12%), methyl palmitate (C16:0, ~4–6%), and methyl stearate (C18:0, ~1–3%), reflecting the typical fatty acid profile of European rapeseed (canola) oil.
Agnique ME 18 RD-F is chemically stable under normal storage and handling conditions; as a polyunsaturated ester mixture containing linoleate and linolenate groups, it has moderate oxidative stability and should be stored protected from prolonged air exposure, elevated temperatures, and metal ion contamination that could catalyze oxidation.
Agnique ME 18 RD-F is incompatible with strong oxidizing agents, concentrated strong acids, and concentrated strong alkalis at elevated temperatures; it undergoes saponification under strongly alkaline conditions and hydrolysis under strongly acidic or alkaline conditions.
Agnique ME 18 RD-F thermal decomposition or combustion may produce carbon monoxide, carbon dioxide, and irritating organic fumes; it has a very high auto-ignition temperature well above its very high flash point.
Production of Agnique ME 18 RD-F:
Agnique ME 18 RD-F is produced by BASF (Cognis origin) in France through the base-catalyzed transesterification of rapeseed (canola) oil with methanol using sodium or potassium methoxide catalyst, followed by glycerol separation, water washing, neutralization, drying, and filtration to obtain fuel-quality or agrochemical-grade rapeseed oil methyl ester.
Agnique ME 18 RD-F production controls fatty acid methyl ester composition by GC, acid value, saponification value, water content, cloud point, and color to ensure compliance with product specifications for agricultural and industrial use.
Agnique ME 18 RD-F is available from BASF SE through the BASF global supply network and BTC Europe distribution; the product-specific Safety Data Sheet and Technical Data Sheet should be obtained from the local BASF representative prior to use.
