Evolution of organic castor oil from India

Castor oil as we know a reputed raw material for industrial chemicals is often cultivated and processed in fields and oil mills respectively with synthetic inputs to make it available in bulk with desired properties. However, such pretreatments are longer a valid aspect when oil with quality and sustainability is required for certain subset of applications as production of pure natural cosmetics and related skin care products. This conditional demand faced by Wala Heilmittel GmbH, a German firm to market its completely natural skin products based of cold pressed castor oil had made it to formulate an approach of synthetic components free, organic castor oil exchange with India, involving mutual benefits for growers, processors and consumers.  Christine Ellinger, a scientific representative of the firm initiated her actions via contacts with an Indian NGO called Satvik which then functioned with team of eco-minded farmers in cultivation of crops. Her financial assistance to NGO’ advisory council and efforts of Institute of Market Ecology (IMO) certification for product quality successfully boosted up the cultivation of organic castor and the agenda of German firm reached up its peak with co-ordinated assistance from a like minded castor oil entrepreneur, Mr:Nanalal Satra in Gujarat whose dedicated processing facility for organic castor oil production yielded the German raw material of choice ultimately from India.

The face of organic oil cultivation did not wipe off with German initiatives in India but has steadily grown today to a level of 277 tons of castor beans on approximately 1,175 hectares of land with oil yields in excess to supply other prospective companies. The outcomes so far have been fruitful with social and environmental responsibilities and significantly created economic independence for farmers, especially those in Northern arid regions of Kutch who suffered a nightmare in the earthquakes of Gujarat in 2001.

Castor Oil Derivatives for Agrochemicals

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.
