Abstract
Soap and cosmetic products can be made from oil-bearing microbial biomass via the alkaline hydrolysis of glycerolipids and fatty acid esters to fatty acid salts. The saponified microbial oils/lipids can be combined with a variety of additives to produce compositions for use as soaps and other cosmetic products, which may also contain other constituents of the biomass, including unsaponified oils, glycerol and carotenoids, among others.
Claims42
A soap comprising fatty acid salts of saponified microalgal lipid, the soap comprising at least 10% C18, wherein the microalgal lipid contains no more than 500 ppm color-generating impurities, and further wherein the microalgal lipid is saponified by contacting with an aqueous solution containing a base that saponifies the microalgal lipid.
A soap prepared by saponification of microalgal biomass by contacting with an aqueous solution containing a base that saponifies lipid of the microalgal biomass forming fatty acid salts, wherein the microalgal biomass comprises at least 5% lipid by dry cell weight, said soap further comprising at least 10% C18;
- the biomass contains no more than 500 ppm color-generating impurities and the soap comprises the fatty acid salts.
