C13-14 Isoparaffin

What is C13-14 Isoparaffin?

C13-14 Isoparaffin consists of branched-chain hydrocarbons containing 13 to 14 carbon atoms, synthesized from highly purified petroleum distillates through processes like hydrocracking and isomerization. This clear, odorless liquid is a staple in modern cosmetics, appearing in moisturizers, foundations, and hair care items within the emollient and solvent categories. It functions by dissolving lipophilic and some hydrophilic substances, enabling uniform dispersion and stable emulsions while adjusting product thickness and drying speed. In emollient roles, it lubricates the skin's outer layer, promoting a velvety finish and facilitating easy application. Its low molecular weight and volatility allow rapid evaporation post-application, depositing actives without tackiness or heaviness. Valued for chemical inertness, it maintains formula integrity alongside diverse components, including fragrances and preservatives, without promoting microbial growth.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

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

Benefits

Delivers a silky, non-greasy feel to products for comfortable use.

Supports even distribution and absorption of active ingredients.

Enhances skin softening by filling surface irregularities.
