Dimethyl Capramide

Dimethyl Capramide is a fatty-acid amide used mainly as a solvent/penetration-enhancing slip agent, typically at low single-digit percentages in leave-on formulas. While not a classic high-risk allergen, amide solvents and penetration enhancers can increase stinging and barrier disruption in reactive or eczematous skin—especially when paired with acids, retinoids, or other actives. Based on its functional role and the way it can amplify cumulative irritation in real-world routines, I rate it as mild rather than “gentle.” Safety Notes: Dimethyl capramide is used in commercial cosmetics primarily as a solubilizer/penetration-enhancing co-solvent and sensory modifier, most often appearing at low levels (~0.1–2%) in leave-on serums, lotions, and sunscreens to aid solubilization of lipophilic actives/UV filters and improve spread. In high-solvent systems (e.g., anhydrous oil-gels, high-load active/UV filter concentrates, makeup/cleansing oils), consumer-available products can use markedly higher levels, with upper-end market observations around 5–10% where it functions as a primary solvent/sensory agent. Very high levels beyond this are uncommon in OTC skincare due to sensory/irritation and formulation balance constraints, and rinse-off products typically sit on the lower end of the range.
