Ceteareth-6 Olivate

Ceteareth-6 Olivate is a nonionic emulsifier/surfactant (olive-derived fatty acid ester ethoxylate) typically used at low percentages to stabilize creams and improve spreadability. In clinical use it is generally well tolerated, but as an ethoxylated emulsifier it can contribute to barrier disruption or stinging in highly reactive or eczematous skin, especially in leave-on products with multiple surfactants. Given this low-but-real irritation potential in compromised skin, a gentle (not exceptionally gentle) score is most consistent with patient-safety expectations. Safety Notes: Ceteareth-6 Olivate (commonly paired with Sorbitan Olivate as an O/W emulsifier system) is observed at very low levels (~0.1–0.5%) in leave-on lotions/serums where it functions mainly as an emulsion stabilizer or co-emulsifier. Most commercial creams and lotions use it around 1–4% as part of the primary emulsifier blend. High-strength consumer emulsifying-cream bases and rich barrier creams can reach ~6–8% total Ceteareth-6 Olivate to build lamellar structure and stability, with higher levels uncommon due to texture/waxiness and potential for irritation if pushed further in leave-on products.
