Ingredient Info

Sorbitan Isostearate is an emulsifier made from sorbitol (a natural sugar alcohol) and isostearic acid (a fatty acid). It helps blend oil and water-based ingredients together in skincare products, creating a smooth, stable texture.



Benefits

  • Stabilizes product formulations by helping oil and water mix
  • Creates smooth, pleasant texture in lotions and creams
  • Generally well-tolerated in most skincare products

Potential concerns

  • May cause mild to moderate skin irritation in sensitive individuals
  • Rarely can trigger allergic contact dermatitis (less than 1% of people with contact sensitivity)
  • Animal studies showed moderate irritation potential; use lower concentrations if sensitivity occurs

Science: The Cosmetic Ingredient Review Expert Panel concluded this ingredient is safe for cosmetic use under current practices (typically under 10% concentration). Clinical studies show it is generally a mild irritant and non-sensitizing in most users, though some individuals with sensitive skin may experience irritation.
