Abstract
The subject invention provides materials and methods for producing high-HLB sophorolipid-based compositions and/or for increasing the water solubility of sophorolipid compositions. More specifically, the subject invention provides for the production and post-fermentation alteration of SLP molecules, which can be used for formulating a variety of useful compositions.
Claims27
A method for producing a sophorolipid composition with an HLB of 9 or greater, the method comprising:
- obtaining a yeast fermentation product comprising a mixture of hydrophilic and hydrophobic SLP molecules that is produced by cultivating a SLP-producing microorganism;
- functionalizing all, or a portion of, the hydrophobic SLP molecules by converting them into hydrophilic molecules to produce a SLP fraction comprising predominantly hydrophilic SLP molecules;
- and, optionally,
- mixing the SLP fraction with a liquid carrier, with another SLP fraction and/or molecule, and/or with additional components specific to the desired use for the composition.
