Octyldodecyl Stearoyl Stearate
Ingredient Info
Octyldodecyl Stearoyl Stearate is a synthetic ester derived from stearic acid that works as an emollient and thickening agent. It helps create a smooth texture in formulations and conditions the skin by forming a protective layer on the surface.
Benefits
- Smooths and softens skin texture
- Improves product consistency and spreadability
- Creates a lightweight conditioning layer without significant penetration
Potential concerns
- May cause mild irritation in sensitive individuals or at high concentrations (7.5–20% range)
- Can cause mild ocular (eye) irritation if direct contact occurs
- Very limited data available; safety conclusions rely partly on related ingredient profiles
Science: Safety panel review found that 95% of applied Octyldodecyl Stearoyl Stearate remains on the skin surface with minimal penetration, reducing systemic exposure concerns. Clinical testing at typical use concentrations (2–15%) showed non- to mild irritation and no sensitization or mutagenic effects.
