Diisostearyl Malate
Ingredient Info
Diisostearyl Malate is an emollient and texture-enhancing ingredient derived from malic acid and isostearyl alcohol. It's used in cosmetics to create a smooth, silky feel and improve product spreadability on skin.
Benefits
- Creates a smooth, silky texture in formulations
- Helps improve product spreadability and application
- Provides emollient properties for skin conditioning
Potential concerns
- Potential for contact dermatitis in sensitive individuals, particularly linked to trace impurities (isostearyl alcohol) rather than the ingredient itself
- May cause lip irritation in lip care products in susceptible people
Science: A 1987 case study documented contact dermatitis from this ingredient in lipstick, though the reaction was traced to specific impurities (isostearyl alcohol) present in the material rather than the pure ingredient itself. Limited additional peer-reviewed safety data is available for this ingredient.
