Coconut Alkanes

Coconut alkanes are non-volatile emollient hydrocarbons (used broadly as a silicone-like slip agent, often at several percent to high levels in creams/serums) and are generally well-tolerated with low inherent reactivity in patch testing. The main risk is occasional irritation or follicular issues in highly reactive or eczema-prone skin due to occlusion or formula context rather than the ingredient itself, so it rates as very gentle but not fully inert. Safety Notes: Coconut alkanes are used as lightweight, silicone-like emollients/slip agents and can appear at very low levels (~0.1–1%) in lotions/serums primarily to improve sensory feel and spread. In anhydrous consumer products (face oils, hair oils/serums, balms, makeup primers) they are frequently a primary carrier/emollient and can be used at high levels (20–60%+) and in some “silicone-free” oil blends up to ~70% while remaining OTC and not restricted by specific EU/FDA concentration limits (used per general cosmetic safety obligations). Rinse-off cleansers typically sit in the low-to-mid range (often a few percent to ~20%) since the surfactant system, viscosity, and solubilization/emulsification constraints limit how much can be incorporated.
