Preferred plants are rapeseed, soy, corn, sunflower, cotton, cocoa, safflower, oil palm, coconut palm, flax, castor and peanut.

Enzymatic production of hydrolyzed lecithin products (Schmitt, H., and others, Cargill, Inc., Wayzata, Minnesota, USA, WO2005100579A1, October 27, 2005).

Processes for enzymatic modification of lecithin and related materials, and hydrolyzed products obtained by such modification, are disclosed. One particular implementation provides methods for producing a hydrolysed product containing hydrolyzed phospholipids, monoglycerides, and diglycerides. For example, such a method may include the steps of: (a) contacting a starting material, such as a lecithin, which includes a phospholipid component and a triglyceride component, in an aqueous or organic solvent medium, with a first enzyme effective to hydrolyse the phospholipid; and (b) subsequently contacting the product of step (a) with a second enzyme, effective to hydrolyse the triglyceride.

Process for producing fatty acid lower alcohol ester (Fukuda, H., and Nado, H., Kansai Chemical Engineering Co., Ltd., Hyogo, Japan, US6982155B1, January 3, 2006).

The present invention provides a method for producing a fatty acid ester inexpensively and efficiently by reacting a lipase or an intact mircroorganism containing a lipase, an oil and fat, and a linear lower alcohol in a system containing little or no solvent in the presence of water. The intact microorganism has not been treated with a solvent or the like, and is used as such, so that a fatty acid ester can be prepared in a simple manner. An oil and fat, a natural oil and fat such as a vegetable oil and fat, an animal oil and fat, as well as a waste oil thereof can be used. According to the method of the present invention, a reaction proceeds even in the presence of water, so that waste oils containing a large amount of water can be used as a raw material. Therefore, the waste oil to be dumped into the environment can be recycled, and a biodiesel fuel, which hardly pollutes the environment, can be provided at the same time.

Fatty acids, soaps, surfactant systems, and consumer products based thereon (Connor, D., and others, The Procter & Gamble Company, Cincinnati, Ohio, USA, US6992057B2, January 31, 2006).

Novel fatty acids and derivatives thereof such as salts, new surfactant systems comprising one or more of these compounds, consumer products such as laundry products, personal care products, pharmaceutical compositions, industrial cleaners, and the like comprising said compounds or surfactant systems.

Vegetable oil having elevated stearic acid content (Kodali, D., Cargill, Inc., Wayzata, Minnesota, USA, US6994882B2, February 7, 2006).

Vegetable oils having an elevated stearic acid content and a low polyunsaturates content are described. A confectionery product containing oils of the invention is also described.

Synthesis of polyol medium fatty acid polyesters (Howie, J., and others, The Procter & Gamble Company, Cincinnati, Ohio, USA US6995232B2, February 7, 2006).

Processes for the preparation of polyol fatty acid polyesters comprise heating a mixture of polyol, fatty acid ester, emulsifying agent and catalyst. In one embodiment, the fatty acid chains of the fatty acid ester have from about 6 to about 14 total carbon atoms and the emulsifying agent comprises a fatty acid soap having fatty acid chains of from about 16 to about 22 total carbon atoms.

Nail polish remover comprising fatty acid ester and alkyl lactate (Tavares, B., React-NTI, LLC, Lino Lakes, Minnesota, USA, US6998371B2, February 14, 2006).

A nail polish remover is formulated from a combination of solvents derived from naturally occurring materials, which combination consists essentially of a (i) a major proportion by weight ("by wt") of esters of fatty acids having from 16 to 18 carbon atoms wherein the content of linoleic acid ester in the source vegetable oil is less than 60%, and (ii) a minor proportion by weight of a lower (C1-C5) alkyl lactate. The nail polish remover is highly effective yet has good skin conditioning properties, is non-toxic and non- flammable. A visible residue several micrometers thick provides a desirable gloss on the cleaned nails unless it is washed off.
