Household Examples and Practical Uses You do not need industrial equipment to witness the results of a successful mix. The molecules align at the interface between the oil and water, reducing surface tension and preventing the droplets from coalescing, thus creating a stable mixture.
High Shear Mixing Mechanics for Stable Oil and Water Emulsions
Common food-grade examples include lecithin, found in egg yolks, which is responsible for the smooth texture of mayonnaise, and mustard, which contains natural emulsifiers that bind oil and vinegar. The table below outlines common emulsifiers and their typical HLB ranges, providing a clear guide for formulation.
The Science of Immiscibility and Emulsion The fundamental reason oil and water resist mixing lies in their molecular polarity. Water molecules are polar, forming hydrogen bonds with each other, while oil molecules are non-polar and hydrophobic.
High Shear Mixing Mechanics for Stable Oil and Water Emulsions
The pharmaceutical sector relies on oil-in-water emulsions for topical creams and intravenous injections, ensuring the active ingredients are delivered effectively. These agents have a dual nature, containing both a hydrophilic (water-loving) head and a hydrophobic (oil-loving) tail.
