Phospholipids are good emulsifiers because they have both hydrophilic (water-attracting) and hydrophobic (water-repelling) regions in their structure. This allows them to interact with both water and oil-based substances, helping them to form stable emulsions by breaking down large fat globules into smaller droplets and preventing them from re-aggregating.
