Castorseed futures prices fell by Rs.83 to Rs.4,545 per quintal. This is due to the increased supply in the market and lower industrial demand.
At the National Commodity and Derivatives Exchange, castorseed price for the month of February dropped down by Rs. 83 to Rs.4,545 per quintal, with an open interest of 7,370 lots. Near March-month delivery contract also fell by Rs 70, or 1.61 percent, to Rs 4,277 per quintal, with an open interest of 5,770 lots.

Etocas and Croduret (trade names) are vegetable-derived nonionic surfactants which find widespread use in agrochemicals as general emulsifiers and solubilisers. They are of particular value as biodegradable, sustainable alternatives to nonyl phenol ethoxylates. Etocas and Croduret , both marketed by Croda, are ethoxylated castor oil and ethoxylated hydrogenated castor oil respectively.
The emulsion characteristics judged were
1. Ease of dispersion of the surfactant/solvent mixture in water at 25ºC
2. The particle size of the resulting emulsion
Lower molar ethoxylates of castor oil are used as dispersing agents for oil based systems. They are generally considered to present no special hazards. However, as with other nonionic surface active agents of this type, they may be irritating to the eyes as supplied.

Viscosity, the measurement of the internal flow resistance of a liquid, constitutes an intrinsic property of vegetable oils. It is of remarkable influence in the mechanism of atomization of the fuel spray, in other words, in the operation of the injection system. This property is also reflected in the combustion process, whose efficiency depends the maximum power developed by the engine. This work aims at assessing the rheological behavior of castor oil, castor oil biodiesel, and undegraded and degraded biodiesel at different exposure times and temperatures. Castor oil biodiesel presents viscosity higher than diesel oil, but this drawback can be corrected by means of blends of both components at different proportions. The viscosity data indicated that the heat treatment leads to a degradation of the samples accompanied by an increase of the viscosity, probably because of interactions with intermediary compounds. The degraded samples presented a pseudoplastic behavior, once the flow index, m, is smaller than 1.

The castor oil seed has 47–49% of oil. Biodiesel obtained from castor oil has a lower cost compared to the ones obtained from other oils, as due its solvability in alcohol transesterification occurs without heating. The use of biodiesel will allow a reduction on the consumption of petroleum-derived fuels minimizing the harmful effects on the environment. This work wants to provide a thermoanalytical and physical-chemistry characterization of castor oil and biodiesel. Biodiesel was obtained with methyl alcohol and characterized through several techniques. Gas chromatography indicated methyl ester content of 97.7%. The volatilization of biodiesel starts and finishes under inferior temperatures than the beginning and final volatilization temperatures of castor oil. Biodiesel data are very close to the volatilization temperatures of conventional diesel.
In India, the ministry under Mamata Banerjee has re-classified de-oiled cakes and oil meals from Class 110 to Class 120, effective December 27,2010 which will entail a freight rate increase between 11 and 13 per cent. Since oil cake and meals are used effectively as high nutrient bird and animal feeds, the rise in raw material prices will be passed on to consumers.
Solvent Extractors Association (SEA), in a memorandum to the railways minister and chairman of the Railway Board as well as secretary, Ministry of Agriculture, Commerce, Animal Husbandry and Finance, highlighted that de-oiled cakes were locally produced, traded and occasionally exported on wafer-thin margins. This increase in freight rate would make the production of de-oiled cakes unviable thereby forcing many processing plants to decrease their production and thereafter leading to
De-oiled cakes end-use is in manufacture of compound feeds for cattle, poultry and aqua and also as natural fertilisers and hence such a large increase in freight would place great constraint on the viability of dairy and food industry as well as on the farmers. Also, exports of de-oiled cakes, which face stiff international competition from giants in the US and South America, will be adversely affected. In fact, to compete in the international market, the government has granted a 2 per cent incentive under the Focus Product Scheme for exports of some de-oiled cakes and 5 per cent under Vishesh Krishi Gram Upaj Yojana for castor de-oiled cake. The hike in freight will totally nullify the benefit granted to the exporters of de-oiled cakes and would place them at a great disadvantage.
Commenting on the technical outlook, Dharmesh Bhatia, associate VP-Research, Kotak Commodities Services said the following:
Castor Seed January prices are trading firm and has made a contract high of Rs 4,439, next level is at Rs 4,650. Unless price closes below Rs 4,110, buying is advisable at Rs 4,310-4,360, with stop loss of Rs4,225 and target of Rs 4,610.
In Singapore, Legend Venture and Home Touch Holding have started a program to develop 3 million acres over the next five years to cultivate castor in China and unnamed southeast Asian countries.In 2011, Legend and Home Touch expect to develop 30,000 acres, as well as find investors and land. The castor oil is known for its use in lubricants, nylon, paints and soap. While castor oil can be used in biofuels, it has yet to be economically viable in China.
