Myristyl Alcohol
Ingredient Info
Myristyl alcohol is a fatty alcohol derived from natural sources like coconut oil. In skincare products, it functions as an emollient and thickening agent, helping to soften skin and improve the texture and stability of creams and lotions.
Benefits
- Softens and moisturizes skin
- Improves product texture and consistency
- Helps stabilize emulsions in formulations
Potential concerns
- May cause skin irritation, including increased redness and sensitivity, particularly at concentrations of 5% or higher
- Can increase transepidermal water loss (TEWL), meaning it may temporarily disrupt the skin barrier
- Irritation risk appears higher relative to its skin-penetrating effects compared to other fatty alcohols
Science: Research shows myristyl alcohol caused greater skin irritation than some other fatty alcohols tested, with notable increases in skin blood flow and erythema in animal studies. The study notes that further human volunteer testing at concentrations of 5% or lower is needed to establish safety for topical use.
