How It Works
Arlacel® 165 / Lotionpro™ 165 forms stable oil-in-water emulsions by reducing interfacial tension between the oil and water phases. The combination of glyceryl stearate and PEG-100 stearate creates a balanced emulsifier system that ensures uniform droplet distribution, long-term stability, and a pleasant skin feel.
