Patent – Dehydrated Castor Oil As An Animal Feed Supplement

This post discusses an invention which uses dehydrated castor oil  (DCO) as a food supplement to animals. Conjugated linoleic acid (CLA), as a free fatty acid, has been studied extensively as a probiotic feed supplement for pigs, chickens, and other animals. However, the cost of CLA, in its free fatty acid form is relatively high. The inventors thereby, proposed the way of using dehydrated castor oil as an alternative to CLA. DCO contains 25-30% conjugated linoleic acid triglyceride ester (CLA-TG) and 65-70% “normal” linoleic acid triglyceride ester (LA-TG) (i.e., not conjugated).

The inventor has discovered that when DCO is administered as an additive to an animal feed, one or more of the quality indices of the animal’s meat are improved. For example, for pigs in the finishing phase, the inventor has surprisingly and unexpectedly discovered that when the pigs receive an animal feed composition containing an amount of dehydrated castor oil, at least one of the quality indices of the pig’s meat, namely, the iodine value of the meat, is improved. In the case of such pigs, the significantly lowered iodine value heralds a significantly improved fat firmness in the meat, which, in turn, leads to improved slicing and processing of the resulting meat.

DuPont’s Performance Plastics Line To Contain More Than 50% Renewable Materials

DuPont, one of the world’s largest chemical companies, says that its performance plastics line will contain more than 50 percent renewable materials within 15 years. The company is exploring new technologies to make chemical monomers for basic plastics like nylon from carbon-based resources that can be rapidly regenerated.

Two of the three renewable materials in DuPont’s current performance plastics portfolio are based on non-food feedstocks. Hytrel comes from plant waste and Zytel RS comes from the castor bean plant.

Radici Chemiefaser Develops Castor Based Polyamide 6.10 For Needle Punched Materials Production

Radici Chemiefaser, formerly Dorix GmbH, has developed a new bio-based staple polyamide fibre suitable for the production of needle punched non – woven carpet tiles and similar products.

Dorix PA 6.10 has been developed using polyamide 6.10 produced at the Radici Chimica SpA chemical plant in Italy from sebacic acid (64% by weight), a derivative of castor oil and hexamethylenediamine, a chemical intermediate produced in the Radici Group.

India – Researchers Develop Polyurethane Foams Using Castor Oil Polyols

Researchers at the Indian Institute of Chemical Technology,Hyderabad has developed the polyurethane–clay nanocomposite foams by replacing part of the synthetic polyol with castor oil derivatives. Hydroxylated castor oil was converted into diethanol amide by transamidation and the resulting polyol was formulated into water-blown foams. Modified montmorillonite clay was used as nanofiller in different amounts viz. 0.5%, 1.0%, 2.0%, and 5.0% by total weight of the foam formulation. Rheological measurements on the polyol–clay mixtures indicated that up to 1% clay loading there is no significant change in the viscosity with shear rate and beyond 2%, shear thinning occurred. X-ray diffraction studies further substantiated these results. The effect of the modified clay on the density, mechanical properties such as compression strength, compression modulus, and microstructure of the foams were investigated. The filler thus added had a reinforcing effect on the foam as observed in the density and compression strength measurements. Differential scanning calorimetric studies on Tg and dynamic mechanical analyses on the modulus clearly indicated that 1% clay loading and above led to exfoliation and plasticizing effect. Exfoliated nanocomposites in compositions containing 1% clay and more yielded a much higher nucleation rate than intercalated ones leading to reduced cell size as observed by optical and scanning electron microscopy. Thus, castor oil, which is readily available, relatively inexpensive, and environmentally benign nonedible oil, has been successfully used to prepare filled semirigid foams which can find application in insulation and packing.

US Based Start-up Working On Non-toxic Castor Plant

Nova Synthetix, an agricultural biotechnology start-up, based at US,is looking to bring to market a castor-oil plant variety that does not contain a toxin. The company is commercializing a non-toxic castor plant that produces a unique fatty acid in its seed oil which will be used as a high-value chemical feedstock. They are contracting with growers and developing downstream markets for their castor product.

Nova Synthetix, has recently received a $50,000 grant from a private, US based non-profit corporation, named North Carolina Biotechnology Center.

G Protein-Coupled Receptor Mediates the Action Of Castor Oil

Castor oil is one of the oldest drugs. When given orally, it has a laxative effect and induces labor in pregnant females. The effects of castor oil are mediated by ricinoleic acid, a hydroxylated fatty acid released from castor oil by intestinal lipases. Despite the wide-spread use of castor oil in conventional and folk medicine, the molecular mechanism by which ricinoleic acid acts remains unknown. Scientists at the Max Planck Institute for Heart and Lung Research, Germany have elucidated that the EP3 prostanoid receptor is specifically activated by ricinoleic acid and it mediates the pharmacological effects of castor oil. In mice lacking EP3 receptors, the laxative effect and the uterus contraction induced via ricinoleic acid are absent. Although a conditional deletion of the EP3 receptor gene in intestinal epithelial cells did not affect castor oil-induced diarrhea, mice lacking EP3 receptors only in smooth-muscle cells were unresponsive to this drug. Thus, the castor oil metabolite ricinoleic acid activates intestinal and uterine smooth-muscle cells via EP3 prostanoid receptors. These findings identify the cellular and molecular mechanism underlying the pharmacological effects of castor oil and indicate a role of the EP3 receptor as a target to induce laxative effects.

During which, the company stated that Evofuel, one of their subsidiaries, whose mission is the development of second generation feedstock for biodiesel, is in the process of completing the third year of field trials for the advanced castor varieties in northeast Brazil. Evofuel’s  efforts to introduce a commercially viable alternative feedstock for biodiesel based on castor seeds in Brazil and Argentina seem to be strong on the track according to the press release.

 

Germany’s Worlee Cosmetics Launches Castor Oil Based Exfoliants

In Germany, Worlee Cosmetics has developed castor oil based WorléeBeads HCO, which can be used as a cosmetic rinse-off product, replacing PE and PP plastic micro particles as an exfoliant. The product is designed for exfoliation in rinse-off products such as facial scrubs, body scrubs and shower gels.

Due to their low particle size, plastic micro particles (100 – 500 μm) used in cosmetic applications can pass through filter plants and finally end up in great quantities in the oceans and from there to marine life and finally into the human food chain. Plastic micro particles finding their way to landfill may still be potentially harmful for decades due to the very slow decomposition of plastics. The concentration of the toxic, carcinogenic and hormonally acting substances caused by these plastic micro particles will only increases over time and the total risk and impact on humans and the environment has yet to be realised.

WorléeBeads HCO hence offers a safe and environmental friendly alternative.
