ISOCETYL ALCOHOL.

Valuable CAS 36311-34-9 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

Isocetyl Alcohol is a branched-chain fatty alcohol, valued in precision skincare for its emollient and skin conditioning properties. It forms a lightweight, non-greasy barrier that effectively reduces transepidermal water loss, promoting a softer and smoother skin texture. Beyond its direct skin benefits, it acts as a stabilizing agent within formulations.

Science

On the skin, Isocetyl Alcohol functions by creating a fine, non-occlusive film that aids in moisture retention, thereby enhancing epidermal hydration and contributing to a visibly smoother surface. Within cosmetic formulations, it serves as a self-emulsifying agent, crucial for stabilizing oil-in-water systems and optimizing product texture and spreadability.

Stability

Isocetyl Alcohol demonstrates robust stability across a wide pH range, making it suitable for both low and high pH formulations, including those found in sun care and color cosmetics. Its very low water solubility, approximately 0.1727 mg/L at 25 °C, confirms its primary solubility in oils and alcohols.


Safety

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed fatty alcohols, including the structurally similar Isostearyl Alcohol, concluding they are safe for use in cosmetics, a determination reaffirmed in 2005. Isocetyl Alcohol specifically garners low safety concerns from EWG regarding cancer, allergies, and developmental/reproductive toxicity, and is not identified as potentially toxic or harmful by Environment Canada. A clinical study on Isostearyl Alcohol at 25% concentration reported no signs of skin irritation or sensitization in humans.
