Gravity separates phases based on density. Reduce this by shrinking droplet sizes below 1 micron.
Emulsion stability is a major challenge in cosmetic science. Simple formulations often separate over time. Advanced formulators use precise physical chemistry to prevent this. Understanding the Hydrophilic-Lipophilic Balance (HLB) cosmetic formulations an advanced guide book pdf
Advanced guides further explore the role of . For instance, materials like polymeric surfactants play a critical role in stabilizing nanoemulsions, which are prized for their ability to deliver active ingredients deep into the skin. Gravity separates phases based on density
