What is Octyldodecanol?

Octyldodecanol is a branched-chain, saturated primary fatty alcohol with a 20-carbon chain length, typically produced synthetically from petrochemical feedstocks or derived from natural oils. As a clear, odorless, viscous liquid, it belongs to the emollient category in cosmetics, commonly found in lipsticks, foundations, creams, and anhydrous products. It functions by providing lubricity and slip to formulations, mimicking the skin's lipid barrier to reduce friction and enhance spreadability. Additionally, it serves as a solvent for dissolving lipophilic actives, fragrances, and pigments, while contributing to viscosity control and stabilizing emulsions without greasiness. Its low volatility ensures lasting emolliency on skin surfaces.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Fragrance ingredient

Contributes scent character and/or masks base odors, shaping the overall sensory experience of the formula (subject to allergen and IFRA considerations).

Emollient

Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.

Solvent

Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.

Benefits

Supports skin softening and smoothness through emollient action.

Helps retain moisture by improving barrier function.

Facilitates even application and ingredient delivery as a solvent.
