What Sorbitan Stearate does

Helps oil and water stay blended
Keeps creams stable over time
Helps lotions feel smooth

Sorbitan Stearate is made by joining sorbitol, a sugar alcohol, with stearic acid, a fatty acid that comes from plant or animal fats. The result is a mostly oil-loving molecule with a small water-friendly part. That split shape is what lets it sit between oil and water and help hold them together.

Formulators use it mainly to help oil and water blend, often alongside a stronger water-loving emulsifier. Its low HLB number, a rating of how much an ingredient prefers oil over water, tells chemists it leans toward oil. It helps creams stay even and smooth over time, and it gives lotions a fuller, smoother body rather than a thin, runny feel.

Good for

Suits people who want stable, smooth creams and lotions, including moisturizers, body lotions, shaving products and sunscreens.

Is Sorbitan Stearate vegan?
