Polyglyceryl-6 Dicaprate

Polyglyceryl-6 dicaprate is a non-ionic polyglyceryl ester used primarily as a mild emulsifier/solubilizer and emollient, typically included around ~0.5–5% in leave-on products. Available patch-test and clinical use data for polyglyceryl esters suggest low irritation and low sensitization potential, with reactions being uncommon compared with harsher surfactants or ethoxylated solubilizers. In highly compromised skin (eczema flares), any emulsifier can contribute to stinging or barrier disruption in layered routines, so I rate it very gentle but not completely inert. Safety Notes: Polyglyceryl-6 dicaprate is used commercially as a mild, PEG-free nonionic surfactant/solubilizer and emollient, often appearing at low levels (~0.1–1%) in leave-on lotions/serums and micellar-style formulas to aid solubilization and sensorial slip. In rinse-off cleansers and oil-to-milk cleansing products it is commonly used higher (2–10%) as a primary or co-surfactant, and high-strength consumer cleansing oils/balm-to-milk and self-emulsifying oil systems can reach ~15–20% to ensure rapid emulsification upon rinsing. No specific EU/FDA concentration cap is typical for this ingredient in cosmetics; practical limits are driven by phase behavior, viscosity, and irritation potential at very high surfactant loads in leave-on products.
