Abstract
Compositions are disclosed that include PEG-modified triglycerides as a surfactant. The mixtures form stable microemulsions with oils and fatty acids which can be the resultant product, such as lubricants, sunscreens, or triglyceride-based products. These emulsions or microemulsions are stable, irreversible, and can be created at low temperature. These can be used in detergents, rinse aids and the like to form microemulsions to remove oils and greasy soils, such as non-trans fats and fatty acids from substrates/surfaces often without the need for linker or other cosurfactants. Methods of making the compositions/microemulsions are included as well as uses thereof.
Claims25
