Dimer Dilinoleyl Dimer Dilinoleate

Dimer Dilinoleyl Dimer Dilinoleate is a high–molecular weight dimerized fatty-acid ester used primarily as an emollient/skin-conditioning and texture agent, typically at low-to-moderate percentages in creams and balms. As a non-volatile, non-water-soluble lipid with no exfoliating or reactive functional activity, it has a low likelihood of stinging or barrier disruption, and patch-test/irritation concerns are uncommon compared with fragrances, acids, or reactive preservatives. Rare irritation can still occur in highly reactive eczema patients or in heavily occlusive formulas, so it is best categorized as very gentle rather than fully inert. Safety Notes: Dimer Dilinoleyl Dimer Dilinoleate is an oil-phase emollient/structuring ester commonly used at very low levels (~0.1–1%) to improve slip, reduce tack, and aid sensory feel in lotions/serums, and at moderate levels (2–15%) as part of the main emollient blend in leave-on creams and balms. In high-oil anhydrous consumer products (lip balms, ointment/balm sticks, barrier balms, and some face oils), it can be a major component of the oil phase and is observed up to ~35% while remaining within typical global cosmetic regulatory allowances (no specific EU/FDA concentration cap; usage limited by sensory, viscosity, and compatibility). Rinse-off products generally sit at the low end because oil-phase load is lower and the benefit is primarily sensory rather than functional structuring.
