Compositions of cosmetic, personal care and skin care products derived from lipid feedstocks and methods to produce the same

Abstract

Lipid compositions derived from a solvent-extracted distillers oil of a dry grind ethanol process and lipid compositions included in cosmetic products, personal care products, skin care products, nutraceuticals, bio fuels, bio-lubricants, oleo chemicals, nutritional products, other bio-products, and animal feed compositions. Concentrations of lipid components.

What is claimed is: 
     
         1 . A lipid composition derived from a solvent-extracted distillers oil of a dry grind ethanol process comprising:
 triglycerides content not less than 96% w/w;   free fatty acids content not greater than 4% w/w;   total moisture and insolubles content not greater than 1.5% w/w;   total carotenoid content not greater than 50 ppm w/w;   and at least one component selected from the group consisting of total lutein content not greater than 50 ppm w/w, cis-lutein/zeaxanthin content not greater than 10 ppm w/w, α-cryptoxanthin content not greater than 5 ppm w/w, β-cryptoxanthin content not greater than 5 ppm w/w, α-carotene content not greater than 0.5 ppm w/w, and cis-β-carotene not greater than 0.1 ppm w/w.   
     
     
         2 . The lipid composition of  claim 1 , wherein said free fatty acid content is not greater than 2% w/w and said triglycerides content is not less than 98% w/w. 
     
     
         3 . The lipid composition of  claim 1 , wherein said free fatty acid content is not greater than 1% w/w and said triglycerides content is not less than 98.5% w/w. 
     
     
         4 . The lipid composition of  claim 1 , wherein said total carotenoid content is not greater than 1 ppm w/w. 
     
     
         5 . A composition derived from a solvent-extracted distillers oil of a dry grind ethanol process comprising a concentration of a lipid component wherein the concentration w/w of said lipid component is at least twice a concentration of said lipid component in a lipid feedstock, selected from the group consisting of free fatty acids, α-tocopherol, total tocopherols, total carotenoids, lutein, zeaxanthin, and total sterols. 
     
     
         6 . A composition derived from a solvent-extracted distillers oil of a dry-grind ethanol process comprising a concentration of a lipid component wherein the concentration w/w of said lipid component is one half or less of a concentration of said lipid component in said distillers oil, said lipid component selected from the group consisting of free fatty acids, α-tocopherol, total tocopherols, total carotenoids, lutein, zeaxanthin, and total sterols. 
     
     
         7 . The lipid composition of  claim 1 , wherein said lipid composition is included in a product chosen from the group consisting of nutraceuticals, bio fuels, bio-lubricants, oleo chemicals, nutritional products and other bio-products. 
     
     
         8 . An animal feed composition comprising the lipid composition of  claim 1 . 
     
     
         9 . A cosmetic, personal care, or skin care product comprising the lipid composition of  claim 1 . 
     
     
         10 . The cosmetic, personal care, or skin care product of  claim 9 , chosen from the group consisting of shampoos, hair lotions, skin care products, skin lotions, skin protection products, sunscreen lotion, self tanning products, nail creams, and nail polish. 
     
     
         11 . Nutraceuticals, bio fuels, bio-lubricants, oleo chemicals, nutritional products and other bio-products comprising the lipid composition of  claim 1 . 
     
     
         12 . An animal feed composition comprising the lipid composition of  claim 1 . 
     
     
         13 . A lipid composition comprising:
 free fatty acids of about 5% w/w or less; and   total carotenoids of about 500 ppm w/w or greater.   
     
     
         14 . A lipid composition comprising a phospholipid content greater than that of a feedstock. 
     
     
         15 . A lipid composition derived from solvent-extracted distillers oil of a dry-grind ethanol process comprising a phospholipid content greater than that of said distillers oil from which said composition is derived.
