👉 A depending fluid, also known as an emulsifying fluid or stabilizer, is a substance that helps to maintain the stability of mixtures that would otherwise separate due to their immiscibility, such as oil and water. These fluids typically consist of a combination of surfactants, which reduce the surface tension between the immiscible components, and other additives that prevent phase separation. By forming a protective layer around the dispersed droplets or particles, depending fluids ensure that the emulsion remains homogeneous over time. Common examples include lecithin in egg yolks, xanthan gum in salad dressings, and casein in milk. This property makes depending fluids essential in various industries, including food, cosmetics, and pharmaceuticals, where maintaining the stability of mixtures is crucial for product quality and efficacy.
